  • Patent number: 9561532
    Abstract: A first roll (20) and a second roll (40) of a roll forming device are provided with a plurality of stacked cutting blades (22, 122) and retainers (21, 121). The retainers (21, 121) pass through the stacked cutting blades (22, 122) and receive a first rotating shaft (16) and a second rotating shaft (18). Projections (21a, 121a) are formed on end portions of the retainers (21, 121). When the cutting blades (22, 122) are stacked, the projections (21a, 121a) control positioning operation of the cutting blades (22, 122). With this constitution, when the cutting blades (22, 122) are joined in a stacked state to the retainers (21, 121), the cutting blades (22, 122) in the stacking direction is controlled with the retainers (21, 121).

  • Publication number: 20100192823
    Abstract: The Color Pin Counting System allows needle workers who stitch by hand, and are working on a large design (with 32 to 40 threads per inch) to start and maintain a method of keeping track of threads. The method utilizes 10 pins with jeweled or colored tops. Each pin represents ten linen or canvas threads. After outlining the design area with basting stitches or a marking pen or pencil, one can easily count the threads in the design to find a starting point for stitching. The Color Pin Counting System solves the dilemma of losing place. The primary advantage of the invention is to allow a needle worker to complete a large design while keeping track of the many threads.

  • Publication number: 20100107947
    Abstract: The present invention relates to a system of manual sewing comprising using solid or hollow shapes, that is planar surfaces, to stabilize and display the area being worked on and using both hands to accomplish the sewing tasks. The area to be worked on is spread out and stabilized on a planar surface, and the planar surface itself is stabilized in space with a holding device or by the surroundings. Both hands are then free to do the actual sewing. Pincers and needle holders designed to assist the use in proper use are employed to optimize visualization and to facilitate the actual sewing. The use of eyeless needles with pre-attached thread, preferably swaged-on threads, eliminates the need for threading. Use of curved needles with needle holders facilitates sewing in small spaces. Kits are also contemplated that comprise a variety of sewing crafts of the present invention.

    Abstract: Sewing machines use a foot control pedal for power and speed. When using a machine quilting frame, one balances on one foot while controlling the speed and power of the sewing machine and moving the sewing machine from side to side and to and fro on a carrier. This invention solves these control problems in one hand guided device, permitting a more comfortable two-footed balance. The Machine Quilting Hand Control handle is angled and contoured for ease of use. A governor sets a maximum speed of sewing. A variable speed trigger switch controls the speed. Hook and loop tape attaches the Hand Control to the sewing machine. The cord plugs into the foot control outlet of the sewing machine. The adapter has several input plugs for use with different sewing machines. An inline fuse shuts off the circuit if there is an electrical short or power surge.
