Abstract
Abstract A process and apparatus for image reproduction using a discrete laminated sensitized element comprising a substrate, a resist layer and a receptor sheet, in which a continuous web is adhered to the receptor sheet and then taken up to delaminate the receptor sheet from the sensitized element leaving the hardened or unhardened portion of the resist layer adhering to the substrate as a positive or negative reproduction of the image and the complementary unhardened or hardened image adhering to the receptor sheet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
AN APPARATUS FOR DELAMINATING A RECEPTOR SHEET FROM A DISCRETE SHEET STRUCTURE COMPRISING IN COMBINATION: A. A SUPPLY ROLL FOR A CONTINUOUS WEB, SAID CONTINUOUS WEB HAVING AN ADHESIVE SURFACE, B. AN ELEMENT FOR FEEDING THE SHEET STRUCTURE TO SAID CONTINUOUS WEB, SAID ELEMENT INCLUDING A TRACK TO MOVE THE SHEET STRUCTURE INTO POSITION WHERE IT CAN BE FED TO SAID CONTINUOUS WEB, C. AN ELEMENT FOR ADHERING THE ADHESIVE SURFACE OF SAID CONTINUOUS WEB TO AT LEAST THE LEADING EDGE OF THE RECEPTOR SHEET BY PRESSING THE CONTINUOUS WEB AGAINST THE RECEPTOR SHEET, D. A HEATING ELEMENT COMPRISING AT LEAST ONE HEATING PLATEN FOR HEATING SAID SHEET STRUCTURE BEFORE IT IS CONTACTED BY SAID CONTINUOUS WEB, AND E. A TAKE-UP ROLL FOR SAID CONTINUOUS WEB AND THE RECEPTOR SHEET, SAID TAKE-UP ROLL BEING DISPOSED RELATIVE TO SAID ELEMENT FOR ADHERING SAID CONTINUOUS WEB TO THE RECEPTOR SHEET SO THAT UPON TAKE-UP OF SAID CONTINUOUS WEB, THE RECEPTOR SHEET IS DELAMINATED FROM THE SHEET STRUCTURE.

Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said element for adhering comprises a pair of nip rolls disposed relative to said continuous web so that said continuous web is pressed against the sheet structure.
Claim 4
Dependent Claim
36 words
The apparatus of claim 1 wherein said element for adhering includes heating means for heating said continuous web so that said continuous web and the receptor sheet are adhered to one another by a thermal adhesive.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1 wherein said heating element comprises a pair of heating platens and a means to clamp the sheet structure between said platens.
Claim 6
Dependent Claim
34 words
The apparatus of claim 1 wherein said element for feeding comprises means for inserting the sheet structure between said platens and means for moving the sheet structure from said platens to the nip rolls.
Claim 7
Dependent Claim
46 words
The apparatus of claim 1 comprising a pair of supply rolls and a pair of take-up rolls and in which said element for adhering comprises a pair of nip rolls for compressing each continuous web against the receptor sheet on either side of the sheet structure.
