<p>Gluing apparatus for use with a form collator for collating continuous sheets of paper (P;Pa;Pb;Pc). The collator has a framework 1, a plurality of rollers (3) extending transversely of the framework (1), each roller (3) being driven by a main motor and having a pin wheel (2) for advancing a continuous sheet of paper (P,Pa;Pb;Pc) hung over the roller (3). The gluing apparatus is positioned opposite each sheet of paper (P;Pa;Pb;Pc) and comprises a gear pump (7) having an inlet (12) connected to a glue reservoir (15) through a hose (16) and an outlet (11) provided with a nozzle (14) for applying glue to the paper. The gear pump (7) is driven by a motor (20) to skippingly or linearly apply glue according to input data of a programmable computer (22) responsive to pulse signals received from an encoder (5) arranged to sense advancing movement of the paper (P). In another embodiment (Figure 4), mechanical means such as a cam (131) is provided to swing the gear pump (107) towards and away from the paper (P).</p> |
