    摘要： This invention relates to a method of tearing sections from a continuous web of fibers without causing compression of the fibers at the severance line by grasping the web at spaced portions adjacent to the tearing area, and moving one portion relative to the other portion to stress and tear the web. An apparatus for accomplishing the tearing includes two juxtaposed pairs of jaws, or the like, which receive and engage an intermittently advanced web. One pair of jaws is then displaced from the juxtaposed position to stress and tear the web. The stressing and tearing action substantially eliminates any densified layer or thickened portions between the ends of the section and the engagement line while the engagement of the web creates a transverse densified line near the ends of the sections.

    摘要： In a double woven fabric with an upper layer and a lower layer, provision is made that, in the area of a desired predetermined separation line, a thread system with warp threads and weft threads alternates out of the upper layer into the lower layer and a thread system alternates out of the lower into the upper layer. At both sides of the desired predetermined separation line, the threads alternating between the upper layer and the lower layer and vice versa are separated in the lower layer. Created thereby is a flat textile structure with a predetermined separation line invisible from the viewing side of the surface of the double woven fabric.

    摘要： Equipment for severing a segment from a length of fabric in a thread-adjusted manner has a bench with spaced first and second sides. A clamping system is mounted to the first side for releaseably clamping a first edge of the fabric. A carriage is displaceably mounted to the bench and is adapted for being displaced from the first to the second side. First and second adjacently disposed rotatable rollers are mounted to the carriage for engaging and ripping the fabric. A cylinder and piston system for displacing the carriage is mounted to the bench.

    摘要： 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.
