Abstract: The present invention relates to a striping apparatus of a circular knitting machine, comprising: a selector, a controller, a yarn-feed unit, and a drive unit. The yarn-feed unit has two portions; the first portion includes a yarn-changing plate, which feeds a yarn into a yarn-entering position, and the second portion includes a movable blade, which clips the tail of the yarn when standby and cuts off an old yarn so that the old yarn can depart from fabric when changing yarns and the operation can back to the standby state. In the preferred embodiments of the present invention, different cams respectively drive the yarn-changing plate and the movable blade, and even though a new yarn and an old yarn are farther spaced, the timings of the cams can be adjusted to release the tail of new the yarn from the movable blade before it is torn off.

Abstract: 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.

Abstract translation: 描述了一种设计用于最小化针头磨损但是相对容易螺纹的纱线架。 纱线托架包括具有用于接收纱线并将其引导到针织机的针的孔的纱线引导器，以及固定到引导件的柔性非金属保护板，使得防护板的至少一部分覆盖至少一个 导向板中的孔的一部分，以减少织针的钩进入孔的趋势。 防护板理想地由诸如聚氨酯的聚合物材料制成，并且优选地具有约50-70的肖氏A硬度。 护板优选是可变形的，使得操作者可以在将纱线穿过纱线导引孔的过程中从纱线导向器向外弯曲，但是当弯曲力被释放时，防护板容易恢复其初始未变形的构型。

Abstract: Double-cylinder circular knitting machine for hosiery or the like. The machine comprises a lower needle cylinder having a substantially vertical axis and an upper needle cylinder that is arranged above and coaxially with respect to the lower needle cylinder. A plurality of axial grooves is formed in the skirt of the needle cylinders and each groove accommodates a double-beak needle that can move axially along the corresponding groove. In each one of the grooves there is a lower pusher, which is arranged below the needle and faces the lower head of the needle with its upper end, and an upper pusher, which is arranged above the needle and faces the upper head of the needle with its lower end. Cams are provided for the actuation of the lower pushers and of the upper pushers to make them slide upwards or downwards in their respective grooves to push up or down the interposed needles located in the lower or in the upper needle cylinder or to transfer the needles from the lower to the upper needle cylinder or vice versa.

Abstract: An impact protection device for a rod for positioning thread guides in a circular knitting machine. The thread guide has an approach and spacing unit formed of a rod and crank system. The end of the rod carries the thread guide and an intermediate region of the rod has a longitudinal slot which is slidably guided on a stud that is rigidly coupled to a fixed arm. The device has a compression spring mounted on the stud which presses the rod against the arm. Elastic elements mounted on a rod articulation pivot pus the rod against the crank. The spring and elastic elements allow small movements of the rod from the plane of arrangement of the path of the rod in case of impact with, or scraping against, another rod.

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.

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: This invention relates to an apparatus for selective positive feeding of a plurality of yarns (Fa-Fd) to striping knitting machines, comprising a plurality of yarn feeding units (1), each having a number of yarn feeding devices. The invention proposes to use a single electromagnet (9) in each yarn feeding unit to move the yarn control elements (7'a-7'd) of all yarn feeding devices from their feeding to their non-feeding positions by means of a uni-directional coupling between the electromagnet (9) and the control elements (7'a-7'd) and to move the control elements in the reverse direction by means of an increase in yarn tension when the yarn (Fa-Fd) is being knitted into the fabric.
