Abstract

In binding the edges of a stack of pages or leaves together, it is known to use an adhesive-backed tape to bind the spine of the book. Such a system is shown in the accompanying drawing, in which the incipient book 2 is engaged between a pair of jaws 4 which are forced together in the direction indicated by the arrows so as to present a planar spine surface 6. Aligned with the spine is a central rib 8 of thick, hot melt, adhesive secured to the central portion of a flexible tape backing 10. The borders of the tape are provided with thihner strips of adhesive 12, which may be of either the hot melt or pressure-sensitive type, the respective portions of the tape 10 being used to flap the book and seal the covers.

ADHESIVE TAPE TRANSPORT SYSTEM (Cont'd)

Handling the tape after the adhesive has been heated or otherwise sensitized is simplified by enclosing the tape borders in longitudinally-extending chambers 14, each housing a movable rubber drive band 16. The bottorn part of each housing 14 as viewed is also provided with means for sucking air from it, so that the overlying portions of the tape 10 are sucked into contact with the drive bands 16. Alternatively, if the clearance between the housing 14 and the tape can be controlled closely en...
