Abstract
Abstract The present invention is directed toward the production of a roller or rollers which impart to plastic material in strip form and of indeterminate length a surface resembling a sueded material. The produced surface is seamless and continuous. Heretofore plastic material to reproduce sueded finish was not and could not be produced with an embossing roller since an embossing roller did not reproduce the genuine suede look or feel. Hand engraved rollers, etched rollers and the like have failed to give a genuine suede look to plastic material and sheeting. Small area sections may be reproduced by hand engraved flat plates then abrading of sheet or roll material which is expensive and wasteful has also been accomplished. Embossing rolls have been used for producing special surfaces such as skin reproductions for example, lizzard, alligator, etc. The use of a grit to produce a reverse master which is then electro-reproduced with the resulting sleeve mounted on a roller produces the desired embossing surface and the sueded reproduction. Grit surface material from AR 3 to 3 M 50 has and may be employed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
289 words
A method of forming an embossing roller having an outer surface contoured to produce in and on one face of a strip of plastic sheeting a grit or suede finished surface without further finishing of said embossed surface, the method steps including: (a) providing a support roller of metal and of a given length and of regular diameter; (b) forming and securing an outer surface on the support roller of a selected grit surface made from externally furnished grit material, said grit surface formed of hard metal and with a substantially true representation of the externally furnished grit, said grit surface formed on the embossing roller by; (c) applying a wet adhesive to an outer surface of a support roller; (d) drying or curing this wet adhesive after a given depth of grit is applied to and is impressed into the wet adhesive on the support roller; (e) covering this grit surface by a flexible covering and then curing or drying the flexible covering; (f) removing the cured flexible covering to provide a reverse master in which is reproduced the grit projections; (g) plating the inner surface of the reverse master to produce a plating deposition on said inner surface; (h) securing this plating sleeve on an embossing roller to provide the desired grit formation and reproduction; (i) mounting this roller on a shaft means and carrying this roller on said shaft for a given axial rotation; (j) rotating said roller in a given direction and speed, and (k) feeding said sheet material to and through opposed pair and inwardly turning rollers with the embossing roller one of the opposed pair whereby said embossing roller imparts to the sheet material a grit surface of desired depth, appearance and feel.
Claim 2
Independent Claim
289 words
A method of forming an embossing roller having an outer surface contoured to produce in and on one face of a strip of plastic sheeting a grit or suede finished surface without further finishing of said embossed surface, the method steps including: (a) providing a support roller of metal and of a given length and of regular diameter; (b) forming and securing an outer surface on the support roller of a selected grit surface made from externally furnished grit material, said grit surface formed of hard metal and with a substantially true representation of the externally furnished grit, said grit surface formed on the embossing roller by; (c) applying a wet adhesive to an outer surface of a support roller; (d) drying or curing this wet adhesive after a given depth of grit is applied to and is impressed into the wet adhesive on the support roller; (e) covering this grit surface by a flexible covering and then curing or drying the flexible covering; (f) removing the cured flexible covering to provide a reverse master in which is reproduced the grit projections; (g) plating the inner surface of the reverse master to produce a plating deposition on said inner surface; (h) securing this plating sleeve on an embossing roller to provide the desired grit formation and reproduction; (i) mounting this roller on a shaft means and carrying this roller on said shaft for a given axial rotation; (j) rotating said roller in a given direction and speed, and (k) feeding said sheet material to and through opposed pair and inwardly turning rollers with the embossing roller one of the opposed pair whereby said embossing roller imparts to the sheet material a grit surface of desired depth, appearance and feel.
Claim 3
Dependent Claim
18 words
A method of forming an embossing roller as in claim 1 in which the flexible covering is plastisol.
Claim 4
Dependent Claim
20 words
A method of forming an embossing roller as in claim 1 in which the step of plating is by electroforming.
Claim 5
Dependent Claim
86 words
A method of forming an embossing roller as in claim 1 which further includes forming the grit surface on the embossing roller by applying a wet adhesive to an outer surface of a support roller; drying or curing this wet adhesive after a given depth of grit is applied to and is impressed into the wet adhesive on the support roller; covering this grit surface by a flexible covering made from a plastic sheeting which is heated and urged into formation contact with the grit surface.
Claim 6
Dependent Claim
23 words
A method of forming an embossing roller as in claim 4 in which the step of plating the reverse master is by electroforming.
Claim 7
Dependent Claim
208 words
An embossing roller having an outer surface contoured to produce in and on one face of a strip of plastic sheeting a grit or suede finished surface without further finishing of said embossed surface, this embossing roller including: (a) a support roller of metal of a given length and of a regular diameter to provide a base roller; (b) an outer surface formed and secured to the support roller and having a metallic reproduction of a selected grit surface made from externally furnished grit material, said grit surface formed of hard metal and with a substantially true representation of externally furnished grit, said grit surface formed on a sleeve mounted on said support roller, the grit surface produced by plating a reverse master to provide the metallic reproduction of the grit surface on said sleeve; (c) a shaft means by which the roller is carried for a given axial rotation; (d) means for rotating said roller in a given direction and speed, and (e) means for feeding said strip of sheet material to and through opposed pair and inwardly turning rollers with the embossing roller one of the opposed pair whereby said embossing roller imparts to the sheet material a grit surface of desired depth, appearance and feel.
Claim 8
Dependent Claim
208 words
An embossing roller having an outer surface contoured to produce in and on one face of a strip of plastic sheeting a grit or suede finished surface without further finishing of said embossed surface, this embossing roller including: (a) a support roller of metal of a given length and of a regular diameter to provide a base roller; (b) an outer surface formed and secured to the support roller and having a metallic reproduction of a selected grit surface made from externally furnished grit material, said grit surface formed of hard metal and with a substantially true representation of externally furnished grit, said grit surface formed on a sleeve mounted on said support roller, the grit surface produced by plating a reverse master to provide the metallic reproduction of the grit surface on said sleeve; (c) a shaft means by which the roller is carried for a given axial rotation; (d) means for rotating said roller in a given direction and speed, and (e) means for feeding said strip of sheet material to and through opposed pair and inwardly turning rollers with the embossing roller one of the opposed pair whereby said embossing roller imparts to the sheet material a grit surface of desired depth, appearance and feel.
Claim 9
Dependent Claim
19 words
An embossing roller as in claim 6 in which the plating deposition in the reverse master is by electroforming.
