ABSTRACT:
The splicing of webs of packaging material delivered via a pair of individual feed zones into a common feed zone is accomplished through the use of a pair of cooperating change-over rollers located at the start of the common feed zone. A clamping device is provided for each web and the change-over rollers are provided with projections which cause the leading end of one web to be pinched against the other web to cause the two webs to be spliced together, the other web being subsequently severed at a point immediately upstream of the splice. The clamping devices, change-over rollers and severing devices may all be caused to operate automatically in the proper sequence.
