Abstract

A series of documents 3 are sequentially stacked vertically with the lower edges abutting a stop surface 4. Confronting one side of the lower margin of document stack 3 is a thermal bonding head assembly 5, including an integral heating element 6, selectively reciprocated in the direction of arrow X. At the opposite side of the document stack is a spring-loaded backup plate assembly 7 which resists the terminal motion of the bonding head 5. Each document of stack 3 has a coating of adhesive carried by the surface confronting backup plate assembly 7. After delivery of the second document to stack 3 and following the delivery of each document thereafter, a bond cycle occurs, during which bonding head 5 is reciprocated into engagement with stack 3 to bond the most recently received document to the next preceding document.

Platen to Avoid Adhesive Sticking

A series of documents 3 are sequentially stacked vertically with the lower edges abutting a stop surface 4. Confronting one side of the lower margin of document stack 3 is a thermal bonding head assembly 5, including an integral heating element 6, selectively reciprocated in the direction of arrow X. At the opposite side of the document stack is a spring-loaded backup plate assembly 7 which resists the terminal motion of the bonding head 5. Each document of stack 3 has a coating of adhesive carried by the surface confronting backup plate assembly 7. After delivery of the second document to stack 3 and following the delivery of each document thereafter, a bond cycle occurs, during which bonding head 5 is reciprocated into engagement with stack 3 to bond the most recently received document to the next preceding document.

Backup plate assembly 7 includes a rigid block 8, a resilient rubber pad 9 and a stainless steel screen 10. Imposition of screen 10 between pad 9 and the first adhesive covered surface of document stack 3 prevents adhesion between the stack and backup plate assembly 7 during bonding cycles following delivery of the second and succeeding documents.
