B65l1 1/04; B26f 3/ 00 U.S. Cl. 221-48 21 Claims ABSTRACT OF THE DISCLOSURE A continuous unitary tissue strip folded as described and having its length dimension greater than its Width dimension wherein the strip has perforations essentially across its width dimension; contains transverse folds essentially across its Width dimension in sequential alternate directions and uniformly separated from one another; and contains longitudinal folds substantially along its length dimension.
This invention relates to paper tissues and methods for making them. More particularly the invention relates to continuous strips of folded paper tissue containing perforations therein as more particularly hereinafter described.
So-called pop-up tissues are Widely used today in both the home and in commercial establishments. Such tissues are generally packaged in cardboard storage boxes which also are conveniently adapted to be used as the dispenser of the tissues. The acceptability of pop-up tissues is to a great extent due to the ease with which it is removed from the storage box, i.e. by pulling one tissue segment from the box, about one-half of the next tissue is also pulled out of the box. This half of tissue segment is popped-out of the box and may readily be pulled out of the box thereby bringing about one-half of the next tissue segment with it. In making pop-up tissues it has been common practice to interleave separate tissue segments in alternate sequence in order to provide the popup result. This is an expensive and cumbersome operation. The machinery for making such interleaved tissue segments is comprised essentially of a plurality of Wound tissue rolls which are fed into known interleaving devices whereupon the tissue is cut to size with cutting blades. A parent roll of tissue paper-initially about 2-5 feet in diameter-is required for each tissue segment in the storage box. Therefore, for example, in a storage box containing 200 double ply tissue segments, at least 200 rolls of .double ply tissue paper are required. These rolls are carried on backstands which can be 150 feet long or more. The web from each roll is unwound and folded once along its length. The folds are made on alternate sides of the machine from roll to roll. Each web is then interleaved with the two adjoining webs and the whole is laid with previous webs similarly interleaved to form a rope which is carried upon a feeder belt. At its discharge end the belt has 200 separate webs of tissue paper upon it. The rope is then passed into the cutter section of the machine Where one or more oscillating rotating disc knives cut the rope into segments, each segment being the length of a single tissue. The piles of tissue segments are then packaged into folding storage boxes and put into commerce. The significant problems associated with the size of the plant are apparent.
Accordingly, the present invention provides an efficient and economic pop-up tissue product. The tissue is produced and packaged on relatively simple equipment thereby eliminating the cumbersome equipment of the prior art. The tissue is easily dispensed iirom the storage box and separated into tissue segments. As each segment is separated from the tissue strip, the next tissue segment of the tissue strip is in the pop-up orientation and is ready for removal from the storage box.
Briefly, the present invention comprises a continuous unitary tissue strip which is folded across its Width dimension, each such fold being in the alternate direction thereby providing a zig-zag configuration. These folds are hereinafter referred to as transverse folds. The tissue strip also contains perforations across its Width dimension. These perforations are hereinafter referred to as transverse perforations. As an impotant feature of this invention, the tissue strip is also continuously folded along its longitudinal dimension. These folds are hereinafter referred to as longitudinal folds and it is understood that the longitudinal folds may be folded over or under the tissue strip in a C-fold configuration, or alternatively, the longitudinal folds may be over and under the tissue strip, respectively in a Z-fold configuration. Generally, the longitudinal folds may be described as C-folds or Z-folds in the longitudinal direction when taken in transverse section. In the preferred embodiment of this invention, the longitudinal folds are made so that the longitudinal edges of the tissue strip terminate at a point intermediate the Width of the tissue strip. In other words, the flaps which are longitudinally folded over onto the tissue mid-portion extend to about the center of the tissue mid-portion. This configuration of folds and perforations provides a continuous tissue strip which may be removed and separated as tissue segments from a storage box. Removal and separation of the tissue strip into tissue segments is accomplished =by pulling the tissue strip out of the storage box through an opening therein. When the tissue strip is pulled out of the storage box up to the transverse perforation in the tissue strip, tissue segments are separated from the tissue strip at that transverse perforation by tearing it thereacross. As will be hereinafter more clearly described in connection with the drawings, an important feature of this invention is that at least one free corner of the tissue strip is available through the opening of the storage box, By means of the free corner, the tissue strip may be held and pulled from the storage box and the tissue segment detached therefrom.
In order to more fully describe the invention, reference is now made to the accompanying drawings which describe certain exemplary embodiments thereof.

In accordance with the invention, continuous tissue ;trips similar to that best shown in FIGURES 3, 9, 11 1nd 14 are made on paper folding machines which are Nell known in the art. For example, tissue stripping ma- :erial which is about 8 inches wide on a roll, is continu- )usly unwound and longitudinally folded along its lengthzvise dimensi-on by well known means, such as for exam- Jle by means of a guide plate. The longitudinally folded ,issue strip is then passed through a perforator device, vhere the tissue strip is transversely perforated at preletermined length. Perforating is well known in the art. Fhe longitudinally folded and perforated tissue strips are .hen passed through machinery which transversely folds he tissue strip in alternating opposite directions. The tisiue strip now resembles a continuous and stacked series )f layers of material folded in a zig-zag configuration, or example, as shown in FIGURES 2, 8 and 13 (without he storage box). Such transverse folding machinery is vell known in the art, and may comprise, for example, a )air of rotatably movable plates which alternatively transfersely fold the tissue strip as it is moved through it. The ransverse folds are at substantially uniform distances `rom each other thereby providing a continuous tissue trip product similar to that shown in the figures referred o. In a preferred system, the tissue strip is two-ply in )rder to provide additional strength and absorbency when lsed.
The invention relates particularly to the longitudinal 'olds and transverse folds in combination with the locaion of the transverse perforation in the tissue strips and t will be described in connection therewith. Referring row to the drawings, one embodiment of the tissue of this nvention is shown in FIGURES l-6 and can be seen to tdvantage in FIGURE 3. Although all of the drawings `how a one-ply tissue strip, it is understood that the tissue trip may likewise comprise two or multiple-ply tissue trips. In this embodiment tissue strip 2 is shown as a tontinuous length of tissue paper in a longitudinal Z-fold :onfiguration as described. Longitudinal folds 8 in tissue trip 2 divide the tissue strip into tissue mid-portion 21 .nd upper flap 10A and lower flap 10B. Transverse folds i in tissue strip 2 are in alternative directions thereby )roviding a tissue strip having a zig-zag configuration hown in the drawings. Perforations 7 are shown at about nid-way between transverse folds 6 and extend through he entire tissue strip layer. Longitudinal edges of upper .nd lower flaps A and 10B of tissue strip 2 extend t0 tbout mid-way between longitudinal :folds 8. Perforated `dge 3 is formed by tearing a tissue segment 22 from issue strip 2. Free corner 9 of upper and lower flaps 10A ynd 10B are shown in about the center of tissue strip 2 n tissue mid-portion 21.
FIGURE 1 shows tissue strip 2 of the embodiment of iIGURE 3 in storage box 1 having an opening 4. Through opening 4 tissue strip 2 is seen to comprise upper .nd lower flaps 10A and 10B, tissue mid-portion 21, free Iorner 9, longitudinal edges 5 and perforated edge 3. Tissue strip 2 is conveniently removed from storage box by pulling on free corner 9 formed by longitudinal edge i and transverse perforation edge 3. In order to provide a issue segment (such as tissue segment 22) tissue strip 2 s pulled out of storage box 1 until perforation 7 is eached. At that point, tissue segment 22 is detached rom tissue strip 2 along perforations 7.
FIGURE 6 shows tissue segment 22 detached from issue strip 2 and comprises upper and lower fiaps 10A and 10B, tissue mid-portion 21, longitudinal folds 8, transverse fold 6, perforated edges 3 and free corner 9.
In FIGURE 4 tissue strip 2 is shown in a sectional side view wherein the zig-zag configuration created by transverse folds 6 in sequential alternate direction are clearly shown.
The Z-fold configuration created by tissue mid-portion 21, and upper and lower flaps 10A and 10B having longitudinal `folds 8 and longitudinal edges 5 is clearly seen in FIGURE 5.
FIGURE 2 shows the embodiment of FIGURE 3 in storage box 1. In this view there are shown perforations 7, transverse folds 6, transverse perforated edge 3, and enumerated only for illustration but not by way of limitation, tissue mid-portion 21 and lower flap 10B.
Ano-ther embodiment of this invention is shown in FIGURES 7-9 and can advantageously be seen in FIG- URE 9. In this embodiment tissue strip 12 is a continuous length of tissue palxer in a longitudinal Z-fold configuration. The embodiment is similar to that as shown in FIGURE 3, however, perforations 17 are in alternate layers of the folded tissue stripping. In this embodiment a storage box 11 is advantageously used wherein the lengthwise dimension B of storage box 11 shown in FIG- URES 7 and 8 is substantially reduced in relation to the lengthwise dimension A of storage box 1 shown in FIG- URES 1 and 2. By controlling the transverse folding operation in conjunction with the transverse perforating operation, the configuration shown in this embodiment iS obtained. Of course, the longitudinal length between transverse folds 16 (substantially the B dimension) is reduced relative to corresponding length shown for the ernbodiment of FIGURES 1-6 (substantially the A dimension). In this embodiment, tissue strip 12 is removed from storage box 11 by pulling on free corner 19 which is formed by longitudinal edge 15 and transverse perforation edge 13. In order to provide a tissue segment, tissue strip 12 is pulled out of storage box 11 until perforation 17 is reached. At that point, a tissue segment is detached from tissue strip 12 by tearing the segment from the strip along perforation 17. It is noted that tissue strip 12 comprises two transverse folds 16. The alternating layers of tissue which contain transverse perforation 17 are shown in FIGURE 8.
FIGURES 10 and 11 represent still another embodiment of this invention which differ from the embodiment of FIGURES 7-9 by providing a tissue strip 20 wherein flaps 23A and 23B are folded in the same upward (shown) and downward (shown in a break-away view in FIGURE l1 as it is beneath the tissue strip) direction. This forms the C-fold configuration wherein both longitudinal tissue edges 15 are on the same side of tissue midportion 24. Free corners 19 are substantially adjacent to one another and are available for use in removal of the tissue strip from storage box 11 Shown in FIGURE 10 by means discussed above.
Still another embodiment of this invention is described in FIGURES 12-15. In this embodiment a double set of tissue strips 31A and 31B are transversely interfolded as shown in FIGURE 14. This embodiment provides the advantage of being able to alternate the color or quality of tissue in the same storage box 11. Transverse perforations 17 are shown as coextensive with transverse folds 16 and being in alternate folded layers of tissue strips 31A and 31B. In other words, as shown in FIGURE 13, all of the transverse perforations 17 of tissue strip 31A are coextensive with transverse folds 16 and are on the left hand side of the figure, and all of the transverse perforations 17 of tissue strip 31B are coextensive with transverse folds 16 and are on the right hand side of the figure. Referring specifically to FIGURES 13 and 14 it is noted that perforations 17 are located so as to provide a tissue segment 25 upon detaching that segment from tissue strip 31A or 31B, and also provides, through opening 14 of storage box 11, approximately one-half of a tissue segment from the other tissue strip. The one-half tissue segment is shown generally as numeral 26 in FIGURE 12.
It is noted that in all of the embodiments of this invention which are shown in drawings, the tissue strips contain longitudinal folds which are coextensive with the lengthwise dimension of the tissue strip. These longitudinal folds may be in the same upward or downward direction or may be in alternate upward and downward direction along either side of the tissue strip in the longitudinal direction. In either case, however, it is important that the tissue segment of the tissue strip next in line provide a free corner within the open area of the storage box by which the tissue strip may be removed from the storage box. The tissue segment is detached from the tissue strip by tearing along the transverse perforations as those perforations appear and it is preferable that the perforations appear in the storage box opening. It is understood that the various forms shown in the embodiment may be substituted for one another and that combinations not inconsistent with the present invention are intended to be claimed. For example, the tissue strip of FIGURE 14 may also be a C-fold configuration noting especially that a free corner 19 by which the tissue may be removed from the storage box is always available.
As to the tissue material itself, it is preferably a soft, pulpy non-Woven paper material which is absorbent to moisture. Such papers are well known in the art and may comprise thin layers of cellulose wadding paper. Generally the tissue paper is rolled onto a reel and fed therefrom directly to the folding and perforation apparatus. Rolls of tissue may be thousands of feet long and in several plies. These tissue rolls are well known in the prior art and do not form any part of the present invention.
The storage box is a conventional box, preferably of cardboard construction and containing a suitable openings or openable area, generally, in its top surface. Ordinarily, the tissue strip, for example, the tissue strip shown in FIGURE 9 which has been folded flat, is laid on a flat cardboard cut-out of the storage box. The thickness of the tissue strip stack is dependent upon the height of the box in its constructed condition. However, a tissue strip sufficient to provide about 10G-300 double ply tissue segments is advantageously packaged into a storage box. The upright storage box is then constructed about the tissue strip.
The opening in the storage box may be advantageously made considerably smaller than the usual storage box opening. This is due to unique configuration and construction of the tissue strip which permits removal from the storage box by merely pulling on one free corner rather than the method of the prior art wherein ones entire hand was required to be inserted into the storage box to obtain a tissue segment. The smaller opening also reduces the extent to which the tissue is exposed to the environmental surroundings, thereby contributing to the overall cleanliness of the product.
It will be understood that it is intended to cover all changes and modifications of the drawings of the invention herein chosen for the purpose of illustration which do not constitute departures from the spirit and scope of the invention.
