Patent number: 4947659Abstract: The fabric is withdrawn from the needle cylinder of the knitting machine and is flattened so that the present fabric severing device can periodically sever a predetermined length of the fabric in a transverse direction while the fabric is being produced by the knitting machine. The fabirc severing device includes a hot wire positioned below fabric tensioning rolls of the knitting machine. The hot wire is normally maintained out of the path of travel of the flattened fabric and horizontal movement is applied to the hot wire to move the hot wire against and through the flattened fabric and thereby transversely sever a length of the fabric. A pneumatic transport system is provided for removing the severed length of fabric from a position beneath the hot wire cutting device and transporting the severed length of fabric to a location spaced from the knitting machine.Type: GrantFiled: April 10, 1989Date of Patent: August 14, 1990Assignee: Adele KnitsInventor: Thomas W.

Patent number: 4945734Abstract: A knitwork tensioning device has a fabric locking mechanism normally disposed in the lower needle cylinder of a double cylinder circular knitting machine. The fabric locking mechanism has a set of locking fingers capable of fluid pressure actuation for locking the fabric being knitted against the bottom end of an inner movable tube within the upper needle cylinder. The fabric locking mechanism is itself capable of fluid pressure actuation for movement into the upper needle cylinder. Locked against the inner movable tube by the locking fingers, the fabric is stretched as the fabric locking mechanism travels with the inner movable tube up into the upper needle cylinder under fluid pressure. The upper needle cylinder has also mounted therein an outer movable tube slidably fitted over the inner movable tube.Type: GrantFiled: September 22, 1989Date of Patent: August 7, 1990Assignee: Nagata Seiki Kabushiki KaishaInventor: Kakuji Maruyama

Patent number: 4842661Abstract: A knitted, woven or non woven article such as a glove for example, having a wrist cuff includes an edge binding which is activatable by the application of heat thereto to prevent unraveling of the cuff edge. The bound edge is defined by first and second yarn ends which are knitted or woven together, wherein the first yarn includes a heat activatable, thermoplastic outer covering and the second yarn is defined by a nonthermoplastic, elastic material. The first and second yarns are knitted or woven in a manner to form crossover points therebetween.
