  • Patent number: 3957186
    Abstract: A web of fibers is continuously fed between a rotating tearing apparatus where the web is torn into sections without causing compression of the fibers at the tear line. The tearing apparatus is comprised of two opposed rotating pairs of web holding means or jaws which receive and engage the web. To tear the web, the leading jaw of each pair is angularly displaced away from the corresponding trailing jaw and then returned to a juxtaposed position relative to the trailing jaw. Preferably the jaws are provided with arcuate working surfaces which may be tipped with a resilient material to increase jaw life and to improve the holding characteristics thereof for webs of contoured cross section.
