Abstract: Web splicing apparatus employs a pair of driven nip rolls which controllably feed web from a running roll into a festoon as web is drawn out of the festoon at a constant rate by a downstream web consuming machine. The nip rolls are driven by a DC motor connected in a closed loop servo system which compares the speed of the web entering the festoon with the web line speed to develop a command signal for the motor. During normal operation, the command signal includes a web velocity trim signal developed by monitoring the position of the festoon dancer relative to a selected reference position so as to minimize tension upsets and to maintain the dancer within its control range. During a splice sequence, the command signal comprises a deceleration ramp having a selected slope to provide controlled deceleration of the web to minimize tension upsets and to permit actuation of the splicing nips prior to actual web stop.

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.
