Abstract
Apparatus for winding a web section without using a core, the web section including a plurality of transversely extending perforation lines and wherein a torn web section is removed from a continuously supplied web. The apparatus includes two winding stations that are diametrically opposed on opposite sides of rotatable, circular carrying discs. Each of the winding stations includes a pair of opposed winding heads, and the winding heads each includes a pair of winding pins that extend in the direction of the winding aixs. The pins are rotatably mounted for rotation as a pair about the winding axis and are connected to a rotary drive. The winding pins are also extendable to a winding position and are retractable to a non-winding position. When in the winding position the pins extend outwardly from the winding head and are spaced from each other a distance sufficient to receive a web therebetween, and upon rotation of the winding heads the web is wound into a roll without the need for a core.
