DD202317A5 - FADENFUEHRERNUESSCHEN - Google Patents

Abstract

The invention relates to a structurally improved Fadenfuehrernuesschen, especially for flat knitting machines. In addition to the simple structure and the cost-effective production, a Nachfedern of the Nüsschenkopfes during a replacement movement is safely avoided by the proposed solution. According to the invention, the thread guide has a Nosschen head 1 and a Nosschenschaft 2, which is attached to a moving over the needle beds of a flat knitting machine Fadenfuehrerbuegel. In order to achieve a simple structure, stable and easily replaceable Fadenfuehrernues, the Nosschenkopf 1 and the Nuesschenschaft 2 are integrally made of elastic plastic, such as polyformaldehyde, prepared, and in the Nüsschenkopf 1 a little pipe 8 of hardened steel or ceramic injected or glued.

Fadenführernüßchen

Field of application of the invention;

The invention relates to a Fadenführernüßchen with a Nüßchenkopf and a Nüsschenschaft, which moved to a on the needle beds of a flat knitting machine

Thread guide bracket is attached

Characteristic of the known technical solutions.

Such Fadenführernüßchen must be designed resilient in their shaft to move in their movement over the needle beds of the flat knitting machine when passing on outside the working width of the machine parked and closely staggered Fadenführernüßchen and when passing, for example, on Wareribreithalter resiliently.

A known Fadenführernüßchen is shown in Figure 1 and has a Nüßchenkopf 1 and a Nüsschenschaft 2, The Nüßchenkopf 1 is drop-shaped or wedge-shaped and has a bore 3, through which the thread slides during knitting. The Nüsschenkopf 1 is made of hardened steel, and the surface of the hole outlet is highly polished. _v The nutshell 2, which is connected to the nut head 1, consists for example of spring band steel, so that the thread

Leader nurses when Muteinvorbebeberleiten can dodge each other.

Figure 2 shows a known Nüßchenkopf 1, which has a base plate 4 and a cover plate 5. Between base plate 4 and cover plate 5, a tube 6 made of hardened steel or ceramic is clamped by screwing, which serves as a thread passage. This Nüßchenkopf 1 has the disadvantage that the tube 6 is very bad to clamp and the Nüßchenkopf 1 is very expensive and therefore expensive.

Finally, FIG. 3 shows a further known yarn guide cup, in which the nut head 1 is formed integrally with a shank part 7. The shaft portion 7 is in turn articulated and resiliently mounted in the actual Nüsschenschaft 2, wherein the basic position of the Fadenführernüßchens is always held by spring pressure. This articulated storage the Fadenführernüßchens is very complicated and expensive.

The known Fadenführernüßchen are either consuming and expensive or have the disadvantage that they swing too much when dodging and thus the thread insert is endangered in the needles.

Goal of Brfindimg;

The invention has for its object to provide a Fadenführernüßchen, which is simple in construction and ^: inexpensive to manufacture and with which a Nachschwingen the Nüßchenkopfes ^ after a-evasive movement safely avoided 'is.

Explanation of the nature of the invention:

This object is achieved with a Fadenführernüßchen of the type described above according to the invention that the Nüßchenkopf and Nüsschenschaft are made in one piece from elastic plastic, and that in the Nüßchenkopf a tube of hardened steel or ceramic injected or glued. The elasticity of the plastic and the

H

Structure of Nüsschenschaftes are chosen such that the Fadenführemüßchen can easily dodge, but does not resonate.

The Nüsschenschaft is expedient in the direction of movement of the Fadenführernüßchens from Nüßchenkopf from conically widening. As a result, an additional lateral stability of the Fadenführernüßchens is achieved.

The body of the Fadenführernüßchens is advantageously made of polyformaldehyde (for example, Hostaform C 2520).

The tube in the Nüßchenkopf expediently has tulip-shaped ends bent up at the thread inlet and at the thread outlet. Hereby is achieved that the tube during the injection in the Nüßchenkopf is fixed in a simple manner such that it / or can slide downwards neither upward. Next, the tulip-shaped end bent up at the thread spout has the advantage that the thread, which is pulled almost at right angles over the edge of the tube at this end, runs over a larger radius and is thus spared.

At the end facing away from Nüßchenkopf Nüsschenschafts screw nuts are advantageously injected, whose thread is used to screw the Fadenführernüßchens on the thread guide bracket.

The known Fadenführernüßchen shown in Figures 1-3 have already been described in the introduction.

The Fadenführernüßchen invention shown in Figures 4-6 consists of an integrally made of elastic plastic, e.g. Polyformaldehyde (Hostaform C 2520) sprayed Nüsschenkopf 1 and Nüsschenschaft 2. In the Nüsschenkopf 1 a tube 8 made of hardened steel or ceramic is injected. The tube 8 has tulip-shaped ends 9 and 10, both at the thread inlet and at the thread outlet. By these tulip-shaped bent-up ends 9, 10, the tube 8 is fixed during injection in a simple way in Nüßchenkopf 1, so it can not slide up or down. Next is optimally protected by the tulip-shaped ends 9, 10 of the thread.

The Nüsschenschaft 2 is formed such that it widens conically from Nüßchenkopf 1 from. In the upper part of the nutshell shaft 2, two screw nuts 11 are injected, the thread of these screw nuts 11 being used to screw the thread guide loop onto the thread guide bar just change.
