Abstract

A glue dot binding system in which a rotatable heated arm transfers adhesive from a rod of solid hot melt adhesive to the corner of a sheet and a pressure pad secures the sheet to the previous one. Successive operations enable a corner bound book to be formed.

SHEET TO SHEET BOOKBINDING ADHESIVE APPLICATOR (Cont'd)

A glue dot binding system in which a rotatable heated arm transfers adhesive from a rod of solid hot melt adhesive to the corner of a sheet and a pressure pad secures the sheet to the previous one. Successive operations enable a corner bound book to be formed.

On sensing upstream that a sheet (1) is on its way to a stacking tray (2) (1st sheet is excluded), a first solenoid (3) is energised so that a small heated wiper arm (4) moves from its rest position in contact with an adhesive wire (5) (hot melt), the heater activating the adhesive and coating the underside of the wiper arm (4). The wiper arm then rotates to the glue position over the top of the bind corner
(6). Once in this position, the sensed sheet (I) can arrive in the tray and register over the top of the wiper arm as illustrated. By activating a second solenoid (7) the wiper arm drops against a spring so that it contacts the top of the sheets already in the tray and transfers glue by contact. The mechanism is self- compensating for stack height. The first solenoid (3) is then de-activated and, as the wiper is withdrawn from the book, a glue deposit is left behind. The wiper arm returns to i...
