Abstract
Bottom wrap/three-quarter wrap apparatus having an automatic web feeder for safely advancing a web fed from a supply roll to a main web feeder. The main feed rollers advance one length of the web and a cutter cuts the advanced length, completing one cycle of operation, after which the bottom wrap/three-quarter wrap apparatus is placed under control of a bundle feeder. The main feed roller pair are displaced from one another when the web passes between creasing rollers. When a predetermined length of web has been advanced to the creasing rollers a cutter cylinder moves a blade mounting plate in the cutting direction. A resilient clamping assembly arranged on the mounting plate momentarily clamps the web between the mounting plate and a web guide just prior to severing of the web by the blade, maintaining the web taut during cutting. The cutting blade is rapidly moved back to a position displaced from the web in preparation for a subsequent cutting operation.
