Patent number: 8997671Abstract: A set of sewing disks for controlling the movement of a piece of fabric over the free arm and under the needle of a sewing or quilting machine. Each disk is flat and has an oval or circular configuration and comprises three registered, stacked adhesively attached layers—a first contact layer made of open cell foam, a semi-rigid intermediate stiffener member, and a second contact layer made of closed cell foam. When each disk is placed over a piece of fabric with the lower contact layer is placed adjacent thereto, the individual's fingers are exposed at all times and placed over the opposite contact layer. The intermediate stiffener layer spreads and evenly dissipates the forces exerted by the fingers to the top contact layer to the lower contact layer. Because the finger tips are not in contact with the fabric, soiling of the fabric by the finger tips is prevented.Type: GrantFiled: September 4, 2012Date of Patent: April 7, 2015Inventor: Ellen Holder

Patent number: 6341570Abstract: A method of sewing the toe of a sock is provided which can automatically take out a sock pattern of knitted fabric from a sock knitting machine and sew up the selvedge at the toe portion of the sock pattern of knitted fabric thus improving both the efficiency of production and the energy saving. When a sock pattern of knitted fabric has been fabricated by the sock knitting machine, the transfer needles mounted on a group of transfer needles equipped movable tables are advanced at their tips close to the hooks of knitting needles. Then, the sock pattern of knitted fabric is lifted up and turned inside out by suction to transfer its loops at the toe portion from the knitting needles to the corresponding transfer needles. As a result, the sock pattern of knitted fabric turned inside out is transferred from the sock knitting machine to the transfer needles equipped movable tables.Type: GrantFiled: April 2, 2001Date of Patent: January 29, 2002Assignee: Maruzen Sangyo Co., Ltd.Inventors: Toshifumi Fujiwara, Takeshi Nakahira, Takahiro Ueda, Yusuke Shibata
