Filed June 15, 1932 Patented Mar. 19, 1935 UNITED STATES 1,995,076 METHOD or 'MAKING 'CORN- P As'rEns George H. Perryman, Teaneck, N. .lL,v assignor to The Scholl Mfg. 00., Inc., a corporation of New York Application June 15, 1932, Serial No. 617,304 eolaims. ((1154-2 This invention relates to a method of manufacturing corn plasters and other like articles. The object of'the invention is to provide an improved method by which thesearticles may be 5 rapidly manufactured in quantity; the method employed resulting in an improved product so manufactured that the sanitary characteristics desirable in an article of this kind are fully preserved. 7

Specifically, the inventioncontemplates the feeding of a strip or web of textile materialcoated on one of its faces with an adhesive or sticky substance and provided on its opposite face with a soft cushion material or pad; the

1 perforating of this strip or web, the perforations formed therein comprising the central openings appearing in the eventually-formed corn plas-p ters; the uniting of a strip or web of a thin textile fabric backing with the first strip by adhesively uniting it with the soft back of the first strip, then dieing out the plasters from the composite strip, and adhesively attaching the plasfinishedplasters; Fig. 4 is a view of the opposite face of the plaster; Fig. 5 is a sectional view on the line 5-5 of Fig. 3, looking in the direction of the arrows; Fig. 6 is a plan view of a number of the plasters mounted on the foraminous backing materiahFig. '7 is a'sectional'view through a part of the strip shown in Fig. 2; and Fig. 8 is a sectional view through the dies for stamping the perforations in the strip shown in Fig. 2.

The corn plaster manufactured in accordance with my improved process and shown in its finished state in Figs. 3 to 5, consists primarily of two main portions or layers; one portion consive or sticky face 2 which is placed in contact with the toe and which adhesively holds the plaster in place. The other portion of the plas- 5 ter consists of a backing of a thin cotton fabric manufacture of the in it; Fig.3 is a view of'the front face of one of the stitutes the body of the plaster and consists of a ring shaped pad or annulus 1 having an adhe- 3 which is adhesively attached to the back of the ring shaped portion 1 so that it covers the corn positioned within the central opening 'of the ring 1 when the plaster is Worn. 'These plasters may be made in any shape to suit different re-, "5! I .quirements, theconventionaloval shape being herein shown for convenience." When sold, the plasters are mounted for protective purposes upon a strip or sheetof'an open-mesh textile fabric such as 'crinoline, on'which they are heldby the adhesive material 2: This. backing 2 0 is impregnated .with a suitable substance which permits the plaster tobe easily stripped from it when the'plaster is ready'for applica tion over the corn of 'the user,

' In Carrying-outthe process of the invention, I; utilize a main strip or web 1a, from which the part 1 of the corn plaster is made. i This strip is fed from a roll 11 by any suitable feeding means and passes under a roller 12 and between dies 13, r and 14 which produce the regularlyspaced open ings or holes 15in the strip, these openings or 7 holes constitutingthose formed in the center of the body portion 1 of the finished plaster. The

strip 1a iscomposed of a textile fabric having a 255 soft pad-likeback 17 and its opposite face, shown uppermost in Fig. 1, coated with the adhesive orsticky material 2. As strip or Web 1a is fed between'the dies 13 and 14 which form the holes 15, the disk material '21 punched out of these holes is carried away or otherwise disposed of in any suitable manner, as for instance, by being forced up through the hollow male die 13 by the action of a stud 18 located in the female die.

14, as shown in Fig. 8. Any other means for re- 5 moving this waste material 21 may be used'. I When the perforated web 1a leaves the dies '13 r and 14, it is .moved betweenrollers 22 and 23 in company with a web 3a fed'from a roll135' and of the thin textile fabric which forms the back-l ing 3 of the completed plaster. The web-.3d'has a sticky or adhesive face 24 which may be medicated if desired, and which,when brought in contact with the soft back 17 of the web 1a by the pressure of the'rollers 22 and 23, causes the two strips 1a and 3a, to be adhesively united. The composite strip, consisting of the two layers j 1a and 3a is now fed between dies 25 and 26 which operate on the dotted lines in Fig. 2 to 5 punch out the plasters. The male die 25 forces the plasters shown at 27 in Fig. 1 out of the strip, its upward movement bringing the plasters against the face of a strip 20 of open-mesh fabric or other foraminous material, fed from a roll 28,

As the strip 20 moves away from the dies 26' and 27, hearing. the plasters on its under face,

the plasters so carried are brought across the face of a heated plate 31, which softensthe adhesive located between the face 24 of the fabric backing 3 and the back 17 of the strip 10 so that a very secure adhesion between'the fabric back ing 3 and the body portion 1 of each .of the plasters results. The plate 31 is maintained at such a temperature as not to materially affect the adhesive face 2 of the plasters sothat no difficulty is had by the user of the plasters in stripping'them bodily from their backing strip 20 when he desires to use them.

Thestrip 20 carryingthe plasters 2'7v is neXt carried between knife members 32, which sever the strip into lengths, eachlength carrying the required number of plasters, these lengths being then ready for packing.

While the heating plate 31 is shown as positioned between the dies 25and 26 and the cutters without departing from the spirit of this vention." l p What I claim'is: v I i l. The" process of making corn plasters and the like, consisting in feeding a composite web of fabric, one of the layers of the web being pr'o vided with spaced perforations and-having an exposed sticky surface, in stamping corn plasters from the composite web with 'a -die and forcing them out of the web by the die and'pressing them against a web of open-mesh'textile fabric by the die to adhesively attach them thereto, in moving the plasters over a heated surface while carried on the web of open-mesh textile fabric and in cutting the fabric into sections I 2. The process of making corn plasters and the like consisting in feeding a web composed of a pad-like material provided with a stick surface, perforating the web and forcing waste-material 'out of the perforations'simultaneously with the perforating operation, adhesively uniting a textile fabric backing to the back of the perforated web to thus form a composite web, punching out plasters from the composite web and forcing said plasters away from the web by the punching operation, feeding a web of foraminous fabric adjacent to the composite web so that the punchedout plasters are directed against said foraminous fabric when said plastersare punched out of the composite web, carryingthe backs of the plasters against a heated member while said plasters are attached to the foraminous fabric, and severing the foraminous fabric into lengths.

3. The process of making corn plasters consisting in feeding several fabric webs, at least one of -which is provided with a sticky face, perforating the sticky-faced web and adhesively uniting it with at least a second web, punching corn plasters from the webs thus united and. simultaneously forcing the corn plasters out of the united webs and into contact with a fabric backing to adhesivelyattach them theret and bring: ing the fabric backing plasters adhering thereto over a heated element to intimately bond the plasters to the backing. g

'4. In the process of making corn plastersthe steps of stamping out plasters from a fabric web and forcing the plasters out of and away from the web by the stamping operation and bringing them into contact with a fabric backing to stick them thereon, and in bringing the plasters and fabric backing into contact with a heated element to bond the'plasters to the backing.

5. The process of making corn plasters consisting. in feeding several fabric webs, at least one of which is'ip'rovided with a stickyface, perforating the sticky faced webandadhesively uniting itlwith at least a second web, punching corn plasters from the webs thus united and simul tan'eously forcing the corn plasters out of the united webs and into contact with the fabric backing to adhesively attach them thereto, and bringing the fabric backing and plasters adhering thereto across a heated element'with the fabricbacking remotely disposed from the element to thereby bond the :plasterwebs.

6. The process of making corn plasters'consisting in feeding several" fabric webs, at, least one of which is provided witha, sticky face, perforating the'sticky faced web and adhesivelyuniting it with at least a second web, punching corn plasters from the webs thus united and simultaneously forcing the corn plasters out of the united 'webs and into contact with the fabric backing to adhesively attach them thereto, and bringing the fabric backing and plasters adhering thereto across a heatedelement; the element being located to applya more intensive heat to the contacting facesof' the plaster webs'than. the contacting faces of the fabric-backing and the touching pl etenweb.
