LOOP CUTTING APPARATUS FOR CIRCULAR KNITTING MACHINES

摘要

A loop cutting apparatus for a circular knitting machine which has a circular cylinder including a plurality of knitting needles movable independently includes an upper needle dial located on the circular cylinder and a plurality of yarn cutting needle sets radially centered about the axis of the circular cylinder. Each yarn cutting needle set includes a first cutter needle and a second cutter needle movable against the first cutter needle in a first yarn cutting displacement thereof. The first cutter needle has a yarn holding section leaned by a yarn and collaborated with the two abutting knitting needles at two sides to pick up and draw the yarn to form a pile loop and a first cutter section connected to the yarn holding section. The second cutter needle has a second cutter section staggered against the first cutter section in the first yarn cutting displacement to cut the pile loop.
