To (6 1071mm it may concern: 1
Be it known that I, FREDERICK WV. Moons, a citizen of the United States,residing in Lynn, y in the county of Essex and State of Massachusetts, have invented an Improvement in Apparatus for Forming Designs on Opposite Surfaces of a Sheet of Fibrous Material, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to an apparatus by means of which a flexible sheet or layer of fibrous material may have the same design formed on its opposite surfaces. For this purpose I employ a belt-knife splitting-machine of any usual or suitable construction and adjust the gage-roll with relation to the ring-roll of said machine so as to allow of the passage between them of the flexible sheet or layer and a pattern provided with solid portions and with spaces or openings between said solid portions which cooperate with said machine to form the design on both surfaces of the said sheet or layer.
Other features of this invention will be pointed out in the claims at the end of this specification.
igure 1 represents a suflicient portion of a skin provided with a design which is formed thereon by an apparatus embodying this invention; Fig. 2, a sectional view of a sufficient portion of an apparatus embodying this invention; Figs. 3, 4:, 5, and 6, details in section to be referred to, and Figs. 7 and 8 modifications to be referred to.
Referring to Fig. 2, I have represented the essential elements of a belt-knife splittingmachine, which may be of any suitable or usual construction and which is employed to form a design a on the upper and lower surfaces of a skin or other flexible sheet or layer 1) of fibrous material.
The essential elements of the belt-knife splitting-machine herein shown consist of the bedroll a, the ring-roll (Z, the gage-roll 0, the presser roll f, and the belt or band knife g. The mechanism for imparting movement to the knife g and the rolls of the splitting-machine is not shown, as such mechanism is well known. The gage-rolle and ring-roll (Z have cooperating with them a pattern 5, which is fed between said rolls while bearing on the upper surface of the skin I), which preferably rests upon a yielding backing a, of paper or other like material.
l l l The pattern 1? consists of a strip or sheet of suitable material, such as celluloid or metal, which is provided, as shown in Figs. 2 and 5), with solid portions in the form of projections j and with spaces or openings k, into which portions of the skin are forced to form a design, which is in relief with relation to the portions of the skin compressed by the solid portions j of the pattern. The presser-roll f and gage-roll e are adjusted with relation to the ring-roll (Z so as to afford sufficient space for the passage of the pattern "i, the skin I), and preferably also the sheet a of paper or like yielding material, as will be described. The apparatus may be provided with the usual rigid table I.
In operation with the apparatus herein represented the skin 5 and the yielding backing n are subjected to compression as they are fed between the rolls (6 together with the pattern '1', the projections j of which engage the upper surface of the skin. The projec tions j force certain portions of the skin below other portions of the upper surface of the skin, which other portions enter the spaces or openings in the pattern and are substantially uncompressed, and simultaneously the projections j force certain portions of the lower surface below or beyond the plane of the lower surface and into the path or plane of the movable knife and those portions of the skin which project below or beyond the lower surface of the skin are removed or cut off by the knife 9, thereby forming on the lower surface of the skin the same design which is formed by compression on the upper surface of the skin, so that when the compression is removed, which occurs when the skin has passed through the machine, the skin is provided with the same design on both surfaces.
The operation of the machine may be clearly understood by reference to Figs. 3 to 6. In Fig. 3 the pattern 1', the skin I), and the backing 'n are represented in the normal or uncompressed position before passing through the rolls.
In Fig. at the parts represented in Fig. 3 are shown in the position they occupy while passing between the gage-roll 0 and the ring-roll (Z, and when in this position the projections j on the pattern i are forced into the upper surface of the skin I), and corresponding portions 0 of the skin are forced beyond the level of the lower surface of the skin and into the yielding backing.
In Fig. 5 the projecting portions 0 of the lower surface are represented as being cut by the knife g, and in Fig. 6 is represented the skin after it has passed through the machine.
he skin on its passage between the rolls 6 (Z is subjected to pressure over its entire surface; but the portions which are engaged by the projections j on the pattern are subjected togreater pressure than the portions of the In Fig. 6, 10 represents the uncompressed portions of the upper surface of the skin, and athe compressed portions. The portions which are removed from the lower surface 9 of the skin are represented by r.
It will be observed that the uncompressed portions 12, which enter the spaces or openings k in the pattern, form on the upper surface of the skin a design which is in relief with relation to the compressed portions a and that the portions 9 of the lower surface also form a design in relief with relation to the removed or cut portions 0 of said lower surface, and this deslgn is the same as that formed by the uncompressed portions 0.
The pattern 2' may be made in the form of a sheet or strip, which is laid upon the skin pressed portions of the skin, as represented in Fig. 7 In this case the parts of the skin which are engaged by the solid portions of the pattern are forced below the level of the knife and are out to form the design on the lower surface of the skin.
In the pattern shown in Fig. 7 the solid portions 71 correspond'to the projections 7' of the pattern shown in Fig. 2, while the openings .9 correspond to the spaces Z4.
- In the machine herein shown the gage-roll e and the ring-roll a form compression rolls or devices which hold the skin firmly under compression while beingcut by the knife, and
while I prefer to make the pattern separate from the gage-roll I do not desire to limit my ormed on the invention in this respect, as the pattern may the gage-roll e as represented portions, said solid portions of the pattern being acted upon by the gage-roll to compress portions of a sheet or layer of fibrous material below the cutting edge of said knife to cause said knife to remove portions of said fibrous sheet or layer and form on one surface thereof a design composed of a plurality of component parts corresponding to the design other surface by the solid porpattern, substantially as det1ons of said scribed.
2. In a machine of the character described, compression-rolls between which the sheet or layer of fibrous material is fed, a pattern provided with solid portions and with spaces or openings between said solid portions movable with one of said rolls and engaging one surface of said sheet, and a knife cooperating with said compression-rolls to act on said sheet and remove a portion thereof while firmly held under compression bysaid rolls, substantially as described.
3. In a machine of the character described, in combination, compression devices between which a sheet or layer of fibrous material is fed, a pattern provided with solid portions and with spaces or openings between said solid portions movable with one of said devices and engaging one surface of said sheet to form a design thereon composed of a plurality of component parts, and to simultaneously form proopposite surface of said sheet,
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
