Abstract

Abstract Method and apparatus for the multiple, simultaneous embossment of flexible materials using complementary, character-forming inner and outer bands for each character to be embossed. There is one pair of bands per stage, including an outer, control band and a relatively flexible inner, follower band. Within each stage, the bands are brought into registration with each other in advance of an embossing position but are permitted to move in unregistered contact towards the registration position as the bands are advanced. Beyond the registration position, the bands are separated to accomodate the material to be embossed. In one embodiment, the bands are formed by blocks with respective raised and recessed characters for the inner and outer bands. The blocks are linked together and are hinged in the case of the inner bands.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 201 words
An embossing device having at least one stage and comprising, per stage: an elongated outer control member and an inner follower member, disposed to move over a linear region of travel from a curvilinear region of travel with said control member presenting a smooth inner face to said follower member and said follower member being constituted by blocks which are displaceable relative to one another, whereby the control and follower members are able to slide in contact and relative to one another into registration, one member having raised embossing characters and the other having complementary recessed characters; means in said curvilinear region of travel for permitting the outer and inner members to move in unregistered contact with each other towards registration; registering means at the position of registration for forcing at least two raised characters of one member into corresponding recessed characters of the other member during the movement of said outer control member to an embossing position; means in said linear region between said registration position and said embossing position for separating the registered members to accommodate embossable material therebetween at said embossing position; and means at said embossing position for controllably forcing the separated members against the embossable material.
Claim 2
Dependent Claim 201 words
An embossing device having at least one stage and comprising, per stage: an elongated outer control member and an inner follower member, disposed to move over a linear region of travel from a curvilinear region of travel with said control member presenting a smooth inner face to said follower member and said follower member being constituted by blocks which are displaceable relative to one another, whereby the control and follower members are able to slide in contact and relative to one another into registration, one member having raised embossing characters and the other having complementary recessed characters; means in said curvilinear region of travel for permitting the outer and inner members to move in unregistered contact with each other towards registration; registering means at the position of registration for forcing at least two raised characters of one member into corresponding recessed characters of the other member during the movement of said outer control member to an embossing position; means in said linear region between said registration position and said embossing position for separating the registered members to accommodate embossable material therebetween at said embossing position; and means at said embossing position for controllably forcing the separated members against the embossable material.
Claim 3
Dependent Claim 94 words
An embossing device as defined in claim 1 wherein said stage includes a backing plate that is able to serve as a cover for a succeeding stage and the forcing means at said embossing position comprises an anvil mounted on said backing plate on one side of said control and follower members, a hammer slidably mounted on said backing plate on an opposite side of said control and follower members and means pivotally mounted on said backing plate to act against said hammer for pressing said members, with said material therebetween, against said anvil.
Claim 4
Dependent Claim 16 words
An embossing device as defined in claim 1 wherein the pressing means comprises a toggle linkage.
Claim 5
Dependent Claim 19 words
An embossing device as defined in claim 3 wherein said toggle linkage is pivotally mounted in a flexible bushing.
Claim 6
Dependent Claim 52 words
An embossing device as defined in claim 1 wherein said control and follower members are disposed to move over a linear region of travel between two curvilinear regions of travel, said control member forms a first closed loop, and said follower member forms a second closed loop nested within said first loop.
Claim 7
Dependent Claim 38 words
An embossing device as defined in claim 5 wherein said first closed loop is elliptical and said second closed loop is in contact with said first loop over a major portion of the curvilinear regions of travel thereof.
Claim 8
Dependent Claim 36 words
An embossing device as defined in claim 5 wherein the closed loop of said follower member is of a length which produces a region of slack with respect to the closed loop of said control member.
Claim 9
Dependent Claim 36 words
An embossing device as defined in claim 7 wherein said control and follower members are positioned to cause the region of slack of said follower member to shift position during the movement of said control member.
Claim 10
Dependent Claim 50 words
An embossing device as defined in claim 1 wherein the control member is formed by blocks, including one block for each embossing character, joined together by a continuous band which faces the blocks of said follower member, with the outer surface of the control member blocks bearing character indicating indicia.
Claim 11
Dependent Claim 36 words
An embossing device as defined in claim 9 further including a manually rotatable indexing wheel which engages the blocks of said control member for moving a desired raised and recessed character set to said embossing position.
Claim 12
Dependent Claim 21 words
An embossing device as defined in claim 1 wherein the blocks of said follower member are joined together by flexible hinges.
Claim 13
Dependent Claim 26 words
An embossing device as defined in claim 11 wherein said hinges are V-shaped members, each extending between the surfaces of adjoining blocks of the follower member.
Claim 14
Dependent Claim 34 words
An embossing device as defined in claim 1 wherein said registering means comprises at least one pair of plates between which said members are sandwiched over a two block interval of said follower member.
Claim 15
Dependent Claim 28 words
An embossing device as defined in claim 1 wherein the separating means comprises means positioned between said members and located between the registering means and said embossing position.
Claim 16
Dependent Claim 40 words
An embossing device as defined in claim 14 wherein the registering means is in two parts on opposite sides of said embossing position, and said separating means comprises respective wedges between said members on opposite sides of said embossing location.
Claim 17
Dependent Claim 47 words
An embossing device as defined in claim 1 wherein said registering means comprises a first pair of plates for registering said members during travel in one direction Of motion and a second pair of plates for registering said members during travel in the opposite direction of motion.
Claim 18
Dependent Claim 45 words
An embossing device as defined in claim 1 for the multiple simultaneous embossment of flexible material which comprises a plurality of successive modular stages, each in accordance with claim 21, connected in tandem and means for operating the forcing means of the individual stages simultaneously.
