ABSTRACT:
A continuous web splicing machine has supports for rotatably mounting two rolls of sheet material in tandem, guides for guiding the sheets along upper and lower paths to a splicing station, and an output loopholder for holding a loop length so that the web is supplied continuously even during the spicing operation. The splicing station has upper and lower upstream holders, upper and lower downstream holders, and upper and lower cutters at the splicing station. The cutters and holders are selectively operable in automatic sequences so that fresh sheets can be spliced to the spent sheets alternatingly from the two roll supports. The cutter is formed with knife parts having serrated edges with hooked teeth for improved cutting action. The holder assemblies may be oriented vertically or in other suitable orientations.
