Abstract

The device serves to control the knitting needles in the needle cylinder which has grooves on its outer cylindrical surface in which the knitting needles (3) are moved axially, provided to move the butt (13, 5). On the elbow (5) of the rectangular shape, the knee (13) is slidably slipped by the notch (6) and is fixedly connected to the double-reversible rocker (12) on the opposite side of the needle (3). The platinum (12) is provided at its opposite end with a surface (11) for pushing the rocker (12) into the groove (2), wherein the butt (13) has a face (7), an upper edge (8) and a bottom edge (9) for contact with the lock system.

Description

Circular knitting machine equipment

Technical field.

Circular knitting machine equipped with a needle cylinder on the outer periphery of which are grooved needle grooves, in which together with the needles are stored other sliding elements, called sinkers. These sinkers are operated by means of a locking system, by means of which they slide the needle in the needle groove and thus perform its working movements.

BACKGROUND OF THE INVENTION.

For example, the structure of the sinker and the manner of its placement can be such that it allows, in addition to the axial displacement, also a rocking movement in the needle groove, whereby the sinker functions as a double-reversible lever. Axial displacement is required to move the needle up and down, while its action of the double-lever lever provides for the extension or retraction of its node into or out of the area of action of the lock assembly. Such 'sinkers' are generally involved in the movement of needles, particularly in one direction. However, such needle and double-reversible sinker arrangements are also known, by means of which the needle of the single-cylinder machine can be moved in the groove of the needle cylinder in both directions. The disadvantage of these solutions, however, is that the swinging sinker is mounted as a double-reversible lever directly on the needle on which it rests at the pivot point. For. such a solution must be made with a special needle which requires a deep needle groove to accommodate the needle and sinker joint. From the point of view of the strength of the sinkers, the disadvantage is the weakening of its body at an exposed location in the space of its swinging bearing on the needle, which leads to a reduction in the service life of these components.

and they form one part. The rocker 12 contacts the bottom of the needle groove 2 with the tip of the tip 10 and is provided at the opposite end than it is firmly connected to the butt 13 with a surface 11 for pushing the rocker 12 into the groove 2. The rocker 13 is further provided with a face 7. an upper edge S and a lower edge 9, which serve for contact with a locking system (not shown).

The device according to the invention operates as follows. When the needle cylinder 1 is rotated, the knee 13 contacts the locking system (not shown). in which either the nipple 13 is pushed into the groove 2, the nipple 5 of the needle 3 being inserted into the notch 6 and the position of the needle 3 does not change, or the nipple 13 contacts the locking system with either the upper edge 8 or the lower edge 9, thereby moving the needle 3 upwardly out of the groove 2 of the needle cylinder 7 or sliding the needle 3 downwardly into the groove 2 of the needle cylinder 1 in the axial direction. When the nipple 13 is inserted into the groove 2, it slides out of the groove 2 by the double-reversible swinging sinker 12 so that the swinging sinker 12 rests on the bottom 14 of the groove 2 by the edge of the tip 10. it reverses and the elbow 13 extends out of the groove 2 and reaches a position in which it can be acted upon by a nicely illustrated locking system. Further, the swing sinker 12 and the needle 3 'move in the axial direction by the action of other non-illustrated means located in the groove 2, below the swing sinker 12.
