Abstract
A method of parting a segment from an advancing length of shirred, thin-walled tubing. The method comprises unfolding a portion of the shirred tubing intermediate the ends while the same is advancing by applying a separator to the shirred tubing. After the portion is unfolded, the separator is removed, and the tubing is then parted in its unfolded portion to produce a segment of shirred, thin-walled tubing. This invention also involves an apparatus for parting a segment from a length of shirred, thin-walled tubing. The apparatus includes a support for the tubing and a device for advancing the shirred tubing along the support. A separator is engageable with the shirred tubing to unfold a portion. Parting jaws positioned in advance of the separator are engageable with the tubing for severing the same in its unfolded portion to produce a segment of shirred, thin-walled tubing.
