Abstract
Abstract A device for drying and setting of backing adhesive material applied to backs of books comprising a feeder adjacent a book binding machine including a conveyor belt on which the back of the books are disposed and a gripper for holding the books in a feeding and clamping range. A plurality of HF-electrodes are positioned opposite to the backs of the book blocks and laterally with respect to a longitudinal axis relative to the conveyor belt, the electrodes being mounted in the feeding and clamping range for the gripper adjacent to the book binding machine. An exhaust is provided which removes evaporation leaving said backing adhesive material.

Claim 1
Independent Claim
211 words
A device for drying and setting of adhesive on backs of book blocks, in particular of backing adhesive material applied to backs of books, comprising: a book binding machine including adjacent thereto a feeding means including a conveyor belt on which said backs of said books are disposed and a gripper means for holding said books in a feeding and clamping range; a plurality of HF-electrodes positioned opposite to said backs of the book blocks and laterally with respect to a longitudinal axis relative to and under said conveyor belt, said electrodes being mounted in said feeding and clamping range for said gripper means of said feeding means adjacent to said book binding machine, said HF-electrodes being spaced apart at different distances with respect to each other, the distance of the electrodes with respect to each other is substantially close together at a starting range of said conveyor belt, said HF-electrodes being spaced farther apart at a center range of said conveyor belt, and said HF-electrodes being spaced close with respect to each other in a spacing which substantially corresponds to their distance spacing at said starting range of said conveyor belt at an end of the conveyor belt; and an exhaust means for removing evaporation leaving said backing adhesive material.

211 words
A device for drying and setting of adhesive on backs of book blocks, in particular of backing adhesive material applied to backs of books, comprising: a book binding machine including adjacent thereto a feeding means including a conveyor belt on which said backs of said books are disposed and a gripper means for holding said books in a feeding and clamping range; a plurality of HF-electrodes positioned opposite to said backs of the book blocks and laterally with respect to a longitudinal axis relative to and under said conveyor belt, said electrodes being mounted in said feeding and clamping range for said gripper means of said feeding means adjacent to said book binding machine, said HF-electrodes being spaced apart at different distances with respect to each other, the distance of the electrodes with respect to each other is substantially close together at a starting range of said conveyor belt, said HF-electrodes being spaced farther apart at a center range of said conveyor belt, and said HF-electrodes being spaced close with respect to each other in a spacing which substantially corresponds to their distance spacing at said starting range of said conveyor belt at an end of the conveyor belt; and an exhaust means for removing evaporation leaving said backing adhesive material.
Claim 3
Dependent Claim
12 words
The device according to claim 1 wherein said HF-electrodes are spring mounted.
Claim 4
Dependent Claim
38 words
The device according to claim 1 further comprising: pressure levers including associated pressure roller means thereon for exerting pressure in a range of said backs of said book blocks; and springs operatively connected to and biasing said levers.
Claim 5
Dependent Claim
24 words
The device according to claim 1 wherein said exhaust means comprises a blower positioned beneath said HF-electrodes; and an exhaust positioned above said HF-electrodes.
Claim 6
Dependent Claim
18 words
The device according to claim 1 wherein said HF-electrodes are positioned obliquely with respect to said gripper means.
Claim 7
Dependent Claim
20 words
The device according to claim 1 further comprising: a stationary insulating layer disposed between said conveyor belt and said HF-electrodes.
Claim 8
Dependent Claim
22 words
The device according to claim 6 wherein said insulating layer comprises a material having a low friction coefficient with said conveyor belt.
Claim 9
Dependent Claim
21 words
The device according to claim 1 wherein the speed of said conveyor belt corresponds to the speed of said gripper means.
Claim 10
Dependent Claim
50 words
The device according to claim 1 further comprising: a substantially closed frame having an upper base plate with a plurality of apertures; insulators are mounted on said upper base plate; and electrode support means disposed in said insulators for mounting said HF-electrodes on an upper side of said base plate.
