Abstract: A dial of a circular hosiery knitting machine of the type with a cylinder and dial with yarn cutting device. The dial comprises a dial body which is substantially disk-shaped. The dial is provided with a cutting device, which comprises a plurality of cutting sectors which are distributed around the axis of the dial body and have cutting edges. The cutting sectors are arranged at sectors of the dial body which are intended to be free from needles. The cutting device comprises a cutter which is adapted to abut against the cutting edges of the cutting sectors to cut at least one yarn engaged by one of the cutting sectors in its rotary motion about the axis of the dial body with respect to the cutter.
Abstract: First and second grippers are moveable in the longitudinal direction along needle beds of the weft knitting machine and in a direction that is closer to and away from a needle bed gap of the needle beds, switchable between a state of not holding a yarn and a state of holding the yarn, and moveable independently of each other. A cutter for cutting the yarn is provided on the first gripper. A control section controls the movements and the switching of the states of the first and second grippers, and the cutter so that in a state where the yarn is held by the first gripper and the second gripper, the held yarn is cut with the cutter. The end yarns generated by cutting the yarn with the cutter are not left in cut state, but treated by the first gripper and the second gripper independently of each other.
Abstract: A thread gripping device, for gripping elastic thin thread, in a circular knitting machines, having a supporting element that supports thread guides proximate to a drop or feed, above the needle cylinder and proximate to the needle work area, and bearing at least one elastic lamina element and a thread locking lever pivoted to the supporting element and to rotate scissor-like to catch the thread with a grip portion between the locking lever and the elastic lamina element. The thread gripping region of the locking lever is made of a material with higher friction coefficient, than the remaining part of the locking lever.
Abstract: A device for gripping thread in circular hosiery knitting machines comprising a supporting element fixable to the structure of the machine supporting the thread guides proximate to a drop or feed, above the needle cylinder and proximate to the needle work area, that bears at least one elastic lamina element and a thread locking lever pivoted to the supporting element and rotatable scissor-like with respect to the elastic lamina element to catch the thread with a grip portion between the locking lever and the elastic lamina element. The thread grip portion of the locking lever has two opposite shoulders that delimit bilaterally movement of the thread toward or away from the axis of the needle cylinder.

Abstract: A reinforced webbing material is disclosed for use in furniture, bedding and the like. The webbing includes a flat knitted fabric comprised of conventional yarns such as polyester. Elastomeric yarns or cords may also be, but are not necessarily, integrally knitted into the fabric structure in a warpwise direction. One or more high-performance polymeric reinforcement yarns are integrally knitted into the fabric structure in a lengthwise direction. The reinforcement yarns may comprise aramid fibers, ultra high molecular weight polyethylene, or other suitable high tensile strength polymeric yarns. The reinforcement yarns and elastomeric cords combine with the knitted fabric to provide a substantially elastic webbing material having a finite amount of stretch that is limited by the high performance yarns.
Abstract: A non-elastic yarn is knitted with a core spun elastomeric yarn in a ratio of ends of non-elastic yarn to ends of core spun elastomeric greater than 2:1 to create a knitted fabric having a ridged surface that permits air to pass between the ridges.
Abstract: The invention relates to a thread carrier for a knitting machine, having at least one controllable thread gripper and an inserter (19) whose end at which the thread (16) emerges is in the form of an open channel (76). To simplify the insertion or removal of threads, the thread gripper (109) and the inserter (19) are disposed so as to be movable relative to one another such that the thread can either be inserted into the channel or removed therefrom by the thread gripper (109) itself.
Abstract: A tubular knit fabric article having a two ply end portion that is confined to a reduced tubular size at the outer end thereof by an auxiliary yarn disposed between the plies in an unknit constricting loop and with the ends of the auxiliary yarn knit in the fabric of the plies. The constricting loop is formed by feeding the auxiliary yarn to the needle circle of a circular knitting machine during the knitting of a welt-like portion using an auxiliary yarn feeding attachment that first feeds the auxiliary yarn for knitting the leading end in the tubular fabric, then feeds the auxiliary yarn under tension in a non-knitting position at which the yarn is drawn by the previously knit leading end around the tubular fabric in a constricting loop or loops, and then cuts the trailing end of the auxiliary yarn, which is disposed in the needle circle for knitting in the tubular fabric.
