  • Patent number: 6000245
    Abstract: The invention relates to a yarn changer for knitting machines, with swinging yarn fingers (22c, 22d), which comprise finger bodies and guide bodies (66c, 66d) having cutting and clamping elements (69, 71) slidable on the finger bodies, and with an opener (121) and closer (122) both associated with all yarn fingers in common. In order to reduce the number of moving parts and the noise occurring in operation of the yarn changer, the opener (121) and closer (122) are in such operative connection through a reverse-coupling mechanism (114-120) that they can be actuated in common by an associated cam track (102) acting on a control member (114). The control member (114) is preferably only in the working range of the cam track (102) when a yarn change is to be effected. The invention moreover concerns a knitting machine equipped with the yarn changer, especially a rib circular knitting machine, in which a yarn catcher cooperating with the yarn changer is built into the dial.

  • Patent number: 5237841
    Abstract: The thread feed unit has a supporting block which can be associated with a knitting machine laterally to the needle cylinder or cylinders and is provided with at least one thread guide which has a body provided with an elongated configuration associated with a supporting element and slidable along a direction substantially parallel to its longitudinal extension. The supporting element is associated with the supporting block for oscillation about an oscillation axis transverse to the sliding direction of the thread guide body. A first thread guide actuator is provided and controllably acts on the supporting element to oscillate the thread guide about the oscillation axis, and a second actuator controlling the thread guide body to slide it longitudinally with respect to the supporting element. The first actuator and the second actuator are associated with the supporting block and can be actuated independently of one another.

  • Patent number: 5218845
    Abstract: A circular knitting machine striper control system for controlling the operation of the stripers of a circular knitting machine in changing yarns for patterns automatically. The control system includes a controller carried on a rotary table, having a plurality of swinging plates respectively controlled by solenoids to drive striping fingers of either fixed striper in moving respective striping feeders to change yarns for patterns. A striping finger is not triggered by the respective swinging plate during the rotary motion of the rotary table as the respective solenoid does no work, when yarn changing operation is not needed.

  • Patent number: 4656842
    Abstract: An individual yarn clamping and cutting device is provided for each yarn guide and is moved to an open position in response to movement of the yarn guide from active to inactive position. The yarn clamping and cutting devices are moved to a closed position by cam means carried by the rotating needle cylinder. A yarn guide shifting cam is provided for imparting a slight amount of downward movement to the yarn guides to shift the same from a first upper active position to a second slightly lower active yarn feeding position during introduction of the yarn to reduce the tension in the yarn as the needles begin to knit and to aid in preventing yarn breakage. The yarn guides are mounted to facilitate individual threading of the yarn guides and are mounted for outward tilting movement of their upper ends to a readily accessible threading position while the remaining yarn guides remain in the normal operating position.

  • Patent number: 4404821
    Abstract: A yarn feeder and changer unit for a knitting machine comprises a number of adjacent yarn feeders any one of which can be moved from a yarn trapping position to a yarn feeding position while the others retain severed ends of their respective yarns at the trapping positions. The movement of each feeder to its feeding position comprises an upward component of movement from below the needle level by pivotal movement about a horizontal axis, and forward movement over the needles by a sliding component of movement. The creation of two distinct components of movement for each feeder (pivotal and sliding) enables the feeder path to pass close to but out of the path of the needles, and enables accurate yarn placement to be achieved.

    Abstract: A control device for striper units in a circular knitting machine having a plurality of cam disks, the profil whereof is followed by a respective lever operating a respective thread finger by means of a Bowden cable. Each cam disk is secured to a respective toothed wheel meshing with a further toothed wheel which may be coupled with and uncoupled from, a drive shaft constantly rotating with a predetermined rotational speed. Coupling and uncoupling of the further toothed wheel is controlled by the main chain of the machine so as to selectively cause a rotation of substantially 180.degree. of a respective selected cam disk to bring the corresponding thread finger in operation and another rotation of substantially 180.degree. to bring the corresponding thread finger out of operation. Other cam disks are provided to control in the same manner corresponding thread cutting and gripping means each time an associated thread finger is controlled.
