Patent number: 7810357Abstract: A knitting machine in accordance with the invention includes a thread guide that is associated with a runner. The runner is disposed to hold open the latches of driven out needles of a first group while the needles of a second group are being driven out. Due to the time-staggered driving-out of the latch-type needles and of a first group and a second group, and due to the alternating arrangement of the needles of the first group and the second group, a rising of the knit fabric while the needles are being driven out is prevented without the assistance of holding-down/knock-over sinkers. Inasmuch as a runner that is separate from the thread guide is used for holding open the latches, the position of said runner can be optimally adjusted independent of the position of the thread guide.Type: GrantFiled: December 2, 2009Date of Patent: October 12, 2010Assignee: Groz-Beckert KGInventors: Uwe Stingel, Frank Weihing

Patent number: 6101849Abstract: A yarn carrier designed to minimize needle wear yet which is relatively easy to thread is described. The yarn carrier includes a yarn guide having an aperture for receiving a yarn and directing it to the needles of a knitting machine, and a flexible, nonmetallic guard plate secured to the guide such that at least a portion of the guard plate overlies at least a portion of the aperture in the guide plate, to reduce the tendency for the hooks of the knitting needles to enter the aperture. The guard plate is desirably made from a polymeric material such as polyurethane, and preferably has a Shore A hardness of about 50-70. The guard plate is desirably deformable so that an operator can readily bend it outwardly from the yarn guide while threading a yarn through the yarn guide aperture, yet when the bending force is released, the guard plate readily resumes its initial undeformed configuration.Type: GrantFiled: November 20, 1998Date of Patent: August 15, 2000Assignee: Monarch Knitting Machinery CorporationInventor: Bruce M.

Patent number: 4916925Abstract: The needle latch cushioning member is formed of resilient material and includes an elongate body portion with a free end portion. The elongate body portion is supported in a groove on a yarn feed finger so that the free end portion is positioned to be engaged by and interrupt the swinging movement of the latches of the needles to the closed position as the needles are lowered to stitch loop forming position. The engagement of the latches of the needles with the free end portion of the resilient cushioning member serves to reduce the impact force of the latches against the hooks of the needles and thereby increases the wear life of the needles, without interfering with the feeding of the yarn into the hooks of the needles. When properly positioned, the free end of the resilient cushioning member can be used to guide the yarn into the hooks of the needles.Type: GrantFiled: October 31, 1988Date of Patent: April 17, 1990Assignee: Monarch Knitting Machinery CorporationInventor: Bruce M.

Patent number: 4212174Abstract: The invention relates to circular weft knitting and according to the method described, those stitches which are formed between a cylinder needle and a dial needle are formed around a guide member which lies in the angle between the verges of the cylinder and the dial, these stitches sliding off one end of the guide member. The guide member lies in at least that region of the machine where the needles begin to lift, and preferably extends beyond the position at which the needles slip the loops so that the stitches formed between the cylinder needles and the dial needles are completely formed over the guide member.The invention is particularly useful for controlling the insertion of a lay-in effect yarn, since the guide member provides a containing effect which restricts movement of the lay-in yarn out of the mouth between the stitches already formed on the cylinder needles, and those about to be formed on the dial needles. It is possible to use lay-in yarns of large diameter.Type: GrantFiled: August 12, 1977Date of Patent: July 15, 1980Inventor: Michael W. Shepherd
