Abstract

Abstract A packet-type laminating machine for laminating a card-like member, such as an identification photograph, into a pre-cut pouch or between a pair of protective sheets comprises rotatable feeding rollers and a pair of heated platens adjacent to and rearwardly oriented from the rotatable feeding rollers. The heated platens are adapted to receive the elements to be laminated carried in the packet and heat as well as apply pressure thereto. The forward portions of the heated platens are biased so as to squeeze air from between the elements prior to lamination to prevent entrapment of air between the laminated elements. A pair of expeller rollers are mounted adjacent the rear of the heated platens for drawing the packet containing the laminated elements from between the heated platens, and cooling means are provided adjacent the expeller rollers for cooling the laminated elements. A feeding roller and an expeller roller are mounted rotatably in a common link member in such manner that the feeding rollers will be separated from one another when the carrier or packet containing the laminated elements enters between the expeller rollers.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 118 words
A packet-type laminating machine comprising housing means, rotatable feeding rollers in the housing means, a pair of cooperating heated platens in the housing means adjacent the rotatable feeding rollers, the heated platens to receive the elements to be laminated, which are fed to the heated platens from the feeding rollers, while applying pressure thereto, biasing means for continuously urging forward portions of the heated platens toward one another under pressure to squeeze the air from between the elements prior to lamination in the platens at a lower pressure to prevent entrapment of air between the laminated elements, and rotatable expeller rollers adjacent the rear of the heated platens for drawing the laminated elements from between the heated platens.
Claim 2
Dependent Claim 118 words
A packet-type laminating machine comprising housing means, rotatable feeding rollers in the housing means, a pair of cooperating heated platens in the housing means adjacent the rotatable feeding rollers, the heated platens to receive the elements to be laminated, which are fed to the heated platens from the feeding rollers, while applying pressure thereto, biasing means for continuously urging forward portions of the heated platens toward one another under pressure to squeeze the air from between the elements prior to lamination in the platens at a lower pressure to prevent entrapment of air between the laminated elements, and rotatable expeller rollers adjacent the rear of the heated platens for drawing the laminated elements from between the heated platens.
Claim 3
Dependent Claim 28 words
A packet-type laminating machine as in claim 1 wherein the biasing means comprise springs for urging the forward portion of one heated plaTen toward the adjacent heated platen.
Claim 4
Dependent Claim 53 words
A packet-type laminating machine as in claim 1 wherein a feeding roller and an expeller roller are mounted rotatably in a link member, said link member being supported on the frame means in such manner that the feeding rollers are moved away from one another when the laminated elements enter the expeller rollers.
Claim 5
Dependent Claim 36 words
A packet-type laminating machine as in claim 3 wherein the housing means includes a frame supporting and each link member is pivoted on the frame support rearwardly of the axis of the expeller roller mounted thereon.
Claim 6
Dependent Claim 40 words
A packet-type laminating machine as in claim 3 including cooling means adjacent the expeller rollers for cooling the laminated elements, said cooling means comprising a pair of plates movable relative to one another to contactingly receive the laminated elements therebetween.
Claim 7
Dependent Claim 17 words
A packet-type laminating machine as in claim 5 wherein one plate is biased toward the other plate.
Claim 8
Dependent Claim 26 words
A packet-type laminating machine as in claim 6 wherein a cooling fan is provided in the housing means to cool at least one of said plates.
Claim 9
Dependent Claim 69 words
A packet-type laminating machine as in claim 1 wherein the elements to be laminated comprise a card-like member to be protected and protective film to be secured on opposite sides of the card-like member, the elements being adapted to be inserted into a carrier, whereby in use the carrier is inserted into the feeding rollers and passes between the heated platens in contact therewith to laminate the elements together.
Claim 10
Dependent Claim 151 words
A packet-type laminating machine comprising housing means; rotatable feeding rollers in the housing means; a pair of heated platens in the housing means adjacent the rotatable feeding rollers, the heated platens adapted to receive the elements to be laiminated, which are fed to the heated platens from the feeding rollers, while applying pressure thereto; means for biasing the forward portion of the heated platens toward one another to squeeze the air from between the elements prior to lamination to prevent entrapment of air between the laminated elements; and, rotatable expeller rollers adjacent the rear of the heated platens for drawing the laminated elements from between the heated platens, a feeding roller and an expeller roller mounted rotatably in a link member, said link member being supported on the frame means in such manner that the feeding rollers are moved away from one another when the laminated elements enter the expeller rollers.
