  • Patent number: 5427294
    Abstract: A method for breaking film perforations between a plurality of adjacent films employs an in-feed device, an out-feed device, and a festooner positioned between the in-feed device and the out-feed device. The in-feed device and the out-feed device move the plurality of adjacent films downstream through the festooner, which includes a plurality of rollers extending from a rotatable hub shaft. To perform the method, the hub shaft is first rotated to a home position. Next, a first film is fed through the festooner and into the out-feed device using the in-feed device. The out-feed device moves film downstream at a slower speed than the in-feed device. The hub shaft is then rotated at a high boost speed so that the rollers take up slack in the first film generated by the slower speed of the out-feed device relative to the in-feed device.
