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 web free end is inserted between a pair of rollers, one being driven by a motor and the other being free-wheelingly mounted. The free-wheeling roller swings about a pivot shaft. A cylinder normally maintains the free-wheeling roller displaced from the drive roller. The insertion of the web past the nip formed by the initial feed rollers is detected by a proximity sensor to pull the free-wheeling roller toward the motor-driven roller pinching the web therebetween. A small motor drives the driven roller, moving the web upwardly and into a nip formed by a main feed roller pair. The small motor is then turned off and 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.
