  • Patent number: 6073466
    Abstract: A method and an apparatus, applicable to a knitting machine for the production of collars and the like, for restraining while knitting end portions of cut thread (12, 13) protruding from the edge (5) of said collars into the stitches that compose them. The means for introduction (16) of said thread ends (12, 13) among two next courses of stitches comprises fluid currents (22, 32) that catch the end portions and align them to the stitches while knitting. A combing step of the end portions and stretch them when passing may be provided for. A mobile blowing head (16) and a mobile nozzle (27) are provided for suited to produce said fluid currents (22, 32) while knitting and lower in order not to interfere with thread support means (8, 28). The and portions (12, 13) are restrained among the stitches of the collar without leaving portions or loops protruding from the edge.

  • Patent number: 5613376
    Abstract: The thread cutting and aspiration unit has a vertical cutter supporting post which is shifted towards the axis of a toothed thread trimming disk. A cutting blade associated with each cutter is mounted at the end of a lower L-shaped portion of a corresponding supporting post. The L-shaped portion allows thread to pass beyond the cutter and to be cut by a following blade, so that a considerable length of thread can be aspirated by an aspiration port.

  • Patent number: 5613377
    Abstract: A method and relative equipment, applicable to a knitting machine for the production of collars and similar articles, for restraining, during knitting, the terminal portions of cut thread (12, 13) protruding from the edge (5) of said collars by inserting them inside the courses of stitches which compose them. The means for inserting (16) said thread ends (12, 13) between two successive courses of stitches (2,3 and 3,4) while knitting, comprise at least one nozzle (27, 37) producing a fluid current(22, 32). One of the nozzles (37) may be able to rotate from a first direction (A) of catching the end portion of thread to a second direction (B) aligned with the courses of stitches during the knitting process. Means for inserting can also comprise a first nozzle (27) producing a first jet of fluid (22) for catching the thread end and a second nozzle (37) producing a second jet of fluid (32) for inserting it between two courses of stitches.

  • Patent number: 5555750
    Abstract: At least one pattern thread (8) is bound into the fabric ground in a process for producing a patterned knitted fabric (12). The process uses a warp knitting machine having one needle bar (1), at least one fabric ground laying bar (2,3a), at least one pattern laying bar (9) carrying guides (7) for pattern threads and a knock-over arrangement (9) over which the fabric (12) can be pulled. The pattern thread (8) is grasped, by a grasping device (16), and held between the pattern thread guide and the knock-over arrangement (9). The grasped pattern thread is then severed proximal to the knock-over arrangement, by a cutting device (13). The severed pattern thread is held out of the knitting process for a predetermined time, before being bound again into the fabric ground, no earlier than after a new stitch formation. The excess pattern thread is again severed near the knock-over arrangement (9) and the freed thread cuttings removed.

  • Patent number: 5031422
    Abstract: The invention relates to a circular knitting machine and a method carried out thereon for kniting patterned knitwear with a plurality of yarns. So that it is also possible to make patterns in which any yarns (25) are not worked by a plurality of adjacent needles (12), the floats (26) resulting therefrom are parted from inside the needle circle (10a) and the yarn ends (28) thereby resulting on the side of the associated yarn guide (24) are constantly retained in the capture region of the needles (12) selectable by the selector device for yarn reception. The patterning can thus be effected solely with the aid of the selector devices. Yarn change devices or ring guide bars are not needed (FIG. 2).

  • Patent number: 4887440
    Abstract: A thread cutting device in a circular knitting machine for the production of hosiery goods. The device is arranged on the dial and it consists of a circular cutting saw and a stationary cutting blade cooperating with it. Above the circular cutting saw there is arranged a shaped element so that on a part of the arc in front of the stationary cutting blade with respect to the rotary direction of the circular knitting machine it covers its teeth. Above said part of the arc of the shaped element in the path of the threads drawn by the needles there is arranged a projection for the purpose of lengthening the thread ends between the needle and the circular cutting saw.

  • Patent number: 3949571
    Abstract: A circular knitting machine has a device for cutting and holding elasticized yarns, such as spandex. The device enables the yarn, when detached from the knitting needles, to be cut while holding the free, cut end of the yarn firmly in position so that the yarn later may be easily reattached to the knitting needles when it is desired to reintroduce the spandex yarn into the knit fabric. The device includes a pair of jaws movable in unison, one jaw being effective to grip the yarn and the other jaw thereafter being effective to cut the gripped yarn.
