Zusammenfassung: | A machine for applying a piece of adhesive bearing strip to a stack of sheets having a compressed thickness within one of several thickness ranges, the width of the adhesive strip to be applied being dependent on the thickness range to which the thickness of the stack of sheets corresponds. The machine includes a frame supporting a pair of movable support plates; and each of the plates supports a different one of a pair of caliper members, a different one of a pair of strip guides, and a different one of a pair of platens. The platens are slidably coupled to the plates such that they face each other and the maximum space between the platens is determined by the space between the plates. Means are provided for moving the plates until the caliper members thereon compress with a predetermined force a stack of sheets to be bound and a releasable clutch prevents any separation of the plates after the stack of sheets has been compressed. Since the resulting separation between the plates is dependent on the thickness of the stack of sheets, means responsive to this separation are provided for moving the strip guides into position for supporting a piece of adhesive strip which has a suitable width for binding an edge of the stack of sheets. Motor driven means cause the stack of sheets to drive between the platens a suitable strip in the guides and drive the platens to a position such that the space between the platens is small enough to wrap the strip about the leading edge of the moving stack. Thereafter, the motor driven means press the strip against the stack and provide heat which fixes the strip to the stack to form a book. |
