Abstract
Point needles in a collecting cylinder are driven in a two stage extension process to initially needle or pierce the leading edge of a product web being cut. Once the cut has been made, the needle tips are moved further radially outwardly from the cylinder to secure the cut edge. As the signatures are transferred to a folding cylinder, the needle points are retracted along a single stage retraction curve which is different from the path traveled during the two stage extension process.
