Patented Sept. 10, 1940 UNITED STATES PATENT OFFICE 2,214,593 PAPER REGISTERING MECHANISM Application August 8, 1939, Serial No. 288,945

8 Claims.

The present invention relates to paper registering mechanism and more particularly to a means for controlling the simultaneous feeding of two webs of wrapping material, one to serve as an inner wrapper and the other as an outer wrapper for an article.

Some of the objects of the present invention are to provide a mechanism wherein a single photo-electric cell assembly operates to maintain selected points respectively of two webs of paper in register with a predetermined point; to provide a paper" feed control wherein a single roll of paper serves as the source of supply for two webs of material which are automatically maintained in registering relation with each other and with a predetermined point; to provide a paper feed control wherein a plurality of webs are fed to an operating point in such a way that the replacement time for an exhausted roll of paper is materially reduced; to provide a feed and control for printed paper. which forms the inner and outer wrappers for an article whereby the cost of handling and printing is less than present costs for the same operation; to provide a novel method and apparatus for supplying two webs of material to an article wrapping machine while maintaining exact registration of design between the aforesaid webs; and to provide other improvements as will hereinafter appear.

In the accompanying drawing Fig. 1 represents a diagrammatic perspective of a paper registering and control mechanism embodying one form of the present invention; and Fig. 2 represents a diagrammatic side elevation of the same on a reduced scale.

Referring to the drawing one form of the present invention is shown operating upon a d controlling a web I. of wrapping paper which is drawn from a roll ll rotatably mounted upon a suitable fixed support l2. This web i0 is subdivided longitudinally by a printed line I! into two strips l4 and I5 extending lengthwise of'the web and each in t transversely subdivided by printing into plurality of fields l6 and I I. Each field is of a size and shape such as will enable it to be wrapped about and enclose an article when cut out and separated from the web. While it is preferred to outline the fields by printed boundary lines, this -is not' essential because each field contains a design, cartoon or advertising material which in itself serves that purpose. The fieldsii of one strip it are transversely registered respectively with the fields ll of the other strip I5 and this relation is maintained up to the will point where one strip field then becomes-an inner wrapper for the article and the other strip field then becomes an outer wrapper.

For control purposes a black index i8 or index of contrasting color to the body of the web is printed between each field of one strip, these indicia being preferably alined along one side edge of the web to pass in succession across a focussed light beam from a light source l9 for inspection by a properly located photo-electric cell 20.

Where the fields are transversely divided by a relative heavy line of printing this may serve as the control index for the cell 29 and a specially printed index omitted. By this construction a single photo-electric cell can be used for maintaining accurate registration of two strips of material and the cost of a second cell with its attendant control parts may be saved.

Forfeeding the web If its free end passes be-' tween a cylinder 2! and a control roller 22, the former being preferably of metal and the latter of resilient material. at this point has been divided into two lengthwise strips with one superposed upon the other in accordance with the invention as will be'explained. The pressure of the roller 22 is automatically controlled by the registering mechanism in response to the action of the photo-electric cell 20, all as fully disclosed in Patents No.

2,119,670 and No. 2,108,767 granted respectively The free end of the web 7 cylinder 2i. The preferred arrangement is to locate the roller 23 abovethe roll II and then lead the web downwardly and substantially vertically into the feeding mechanism on its way to the cutting knife and wrapping machine.

In order to divide the web III so that the strips l4 and i5 become separate entities to serve respectively as the outer and inner wrappers of an article, the web It is guided over .a pair of rollers 25 and 26 supportedin relatively close spaced relation so that the portion of the web i0 between the rollers, and 28 is normally sufficiently taut ting edge at a good severing angle with respect to the web [0. As shown the blade 21 is located substantially on themedianlincofthewebbut this is only by way of example and it may be laterally shifted so that the resulting division is into two strips, one wider than the other.

To cause the strips I4 and I5 to assume a superposed relation, a deflecting roller 30 for the strip I4 is supported in rearwardly spaced relation to the strip I5 and serves to divert the strip I4 laterally and angularly towards the strip I5. A

restoring roller 3I for the strip I4 is positioned at such a distance from the roller 30 as will cause the-strip I4 to aline with the registering control feed rollers 2| and 22. The supporting means for the deflecting roller 30 allows the latter to be angularly adjusted so that the strip I4 can be definitely positioned as to angular deflection, this in the present instance being approximately onehalf the width of the strip I4. Also the angular position of the restoring roller 3| is such that the angular path of the strip is converted into a straight away path to the feed rollers 2I and 22. To carry out this action the strip I4 passes under the angularly disposed deflecting roller 30 and over the restoring roller 3|. The strip I5 simultaneously travels over a deflecting roller 32, which is forwardly spaced from the former path of the web, and then under a restoring roller 33 located in close proximity to the roller 3I. The roller 32 is adjustable as to angularity but as shown is positioned to deflect the strip I5 substantially onehalf its width laterally towards the strip I4. The roller 33 in turn diverts the strip I5 into a path parallel to that of the strip I4, the two strips then being in face to face contact and travelling as one, since both are still under the same feed control as regulatedby the roller 22, and the registration as governed by the photo-electric control remains constant. Creep or lag during feeding is automatically corrected by this control, which actuates the worm wheel 34 to shift the roller 22 towards or away from the web as fully explained in the aforesaid patents. A lever 35 makes it possible to operate this control manually and is more particularly for use in initially bringing a new web into registration.

After leaving the restoring rollers 3| and 33 the two superposed strips are led over a fixed guide plate 36 to maintain the strips in face to face relation to enter the feed rollers 2I and 22. A severing knife 31 is located at the point where registration of the indicia takes place and is operated by any suitable mechanism properly timed for exact cutting oif of the respective printed fields. Each such pair of fields as separated from the web enter the wrapping machine (not shown) which function to wrap one field about the article as an inner wrapper and then the other about the wrapped article as an outer wrapper.

' From the foregoing it will be apparentthat an ingenious and novel control has been devised whereby a single paper web is under control by a photo-electric cell for registration with a transversely operating severing knife so that lengths are cut at predetermined transverse distances so that each length displays a complete design or advertising matter. After inspection by the photo-electric cell the web is divided longitudinally into two strips which are fed through a deflecting and restoring mechanism. in such a manner that one strip takes a position in superposed relation to the other and emerge from such mechanism in face to face relation for delivery to the severing device. Since the single web and its subdivided parts are drawn to the severing device by the same feeding means it will be ev dent that correct registration of the single web will be followed by registration of the subdivided parts or strips and consequently it is possible for respective designs in both strips to remain accurately alined and be cut off as complete designs for delivery to the wrapping machine.

While only a single form is shown in which this invention may be embodied, it is to be understood that the invention is not limited to any specific instruction, but might be applied to various forms without departing from the spirit of the invention or the scope of the appended claims. While reference has been made to paper specifically, this is only by way of illustration and this term is to be considered broadly as a web made of Cellophane, Glassine, Pliofilm or any other suitable wrapping material.
