ABSTRACT:
An unwinding machine for wound rolls, e.g. of paper, has holders which can be swung alternately into the unwinding and the splicing positions. A new roll in the splicing position has its leading end engaged by a groove roller which draws the new web between itself and the old web during continued unwinding thereof and a blade roller is pressed against the groove roller to cut through both webs and attach an adhesive strip across the trailing end of the old web and the leading edge of the new web. The residue of the old web continues to be wound up on the blade roller while a small residue of the new web is picked up by the groove roller and carried away.
