  • Patent number: 4238937
    Abstract: A fabric manipulating device for use with a knitting machine of the type having a flat needle bed containing a plurality of equi-spaced knitting needles tricked into the bed includes a carrier that is mounted on the bed for sliding, needle-by-needle movement along the bed to effect loop manipulation. A cam-controlled linking needle is mounted on the carrier in the plane of the knitting needle in opposing relationship thereto for movement to and from the knitting needles to effect the intended knitted loop linking manipulation. A cam-controlled positioning member and loop restricting member, operating in timed relationship with a cam-controlled loop expanding mechanism and stationary loop contacting surfaces, orients and expands a knitted loop retained on the stem of a knitting needle opposing the linking needle to permit the linking needle to enter the expanded loop while a cam-controlled actuator causes the knitting needle to knock-over the loop onto the linking needle.
