<p>An apparatus and method for cross-cutting a traveling web (W) of material, such as paper, while winding the traveling web into successive rolls of a specified diameter includes a laser (48), a pair of spaced adhesive applicators (40, 40') and energy means (44) for activating the adhesive (46) to change it from an essentially inert to a web adhesive state. A pair of horizontally arrayed drums (12, 14) support a core (26) on which the traveling web (W) is wound. Upstream of the core (26), over the lower periphery of one of the drums (12, 14), the on-coming web has its drum-supported surface exposed to a transversely moveable laser (48) which cuts the web transversely to its direction of travel. Upstream of the transversely actuated laser (48) are a pair of adhesive applicator nozzles (40, 40') which are spaced in the web travelling direction and movable transversely with the laser (48). An energy means (44) is mounted between the adhesive nozzles (40, 40') and laser (48) to activate the adhesive sprayed by the nozzles. The travelling web can, thus, be severed by the laser (48) and have its trailing edge glued to the web roll being wound while the leading edge of the severed web can be glued to a new core inserted in the winder between the drums (12, 14).</p> |
