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.
Abstract: Sheet material carrying ink, lacquer, adhesive or some other substance requiring to be dried, is advanced in a path in which its major surfaces are exposed. A drying arrangement, including a source of UV radiation and of incidental IR radiation, is located adjacent this path and directs the UV radiation against the substance to be dried, so as to effect such drying. A cooling arrangement is provided which at least partially surrounds the source of UV radiation in order to counteract the heat of the incidental IR radiation and prevent damage to the sheet material and/or the equipment.
