Abstract
The cyclic application of glue to one face of strip elements continuously delivered edge-to-edge into a reciprocating kicker breech to be collimated into a row forming sheet assembly having thickness equal to the width of individual sheets is controlled by a cascaded series of relays whereby the remotely operated glue guns are not actuated by the final triggering event in the cycle unless a trigger safety device is released by a measurable addition to the cumulative sheet product within the preceding kicker cycle. Additionally, growth of the sheet accumulation is continuously monitored with an actual length comparison to a desired, set-point length. When the desired length is reached, glue gun operation is restrained for one cycle to provide an unbonded interface between the final strip of a preceding sheet and the first strip of a successive sheet.
