Abstract

PROBLEM TO BE SOLVED: To facilitate the manufacture of yarn guide member, and to make the quick adaptation of the yarn guide member to a different kind of yarn at a different thickness possible by forming the yarn guide member into the annular shape, and inserting the yarn guide member into at least one receiver, which is provided on a yarn stopper plate, freely to be changed. SOLUTION: A yarn stopper plate 10 is provided with an opening, which leads a ring 16 into a notch of a receiver 14, under each arm of the receiver 14. The ring 16 is provided with a center opening to be fitted in the notch 14 for insertion of yarn, and fixed to the notch by two engaging projections provided in the notch. The engaging projections are formed with each engaging connection part, which is to be engaged with a recessed part formed at a right angle against the circumferential direction of the ring 16 and which can be easily removed, and the ring 16 can be inserted into the receiver 14 by the engaging projections so that it can be easily changed. Outer diameter of a center opening of the ring 16 is widened to both sides for rise, and a projecting range of the notch is engaged with this range so as to prevent the removal of the ring 16 from the notch in the axial direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn guide arm having a yarn guide member provided on a yarn stopper plate without forming a crack.

[0002]

2. Description of the Related Art A thread arm of this type is known from the applicant's German patent DE 3732879.
The thread restraint plate prevents the thread loop from wrapping around the thread guide member.

[0003]

The problem underlying the present invention is that the manufacture of the thread guide member is simplified and the thread guide member can be quickly adapted to different types and thicknesses of thread. , To improve the known thread guide arm.

[0004]

In order to solve this problem, according to the invention, the thread guide member is constructed as a ring and is replaceably inserted into at least one receiving body provided on the thread stop plate. There is.

[0005]

With such a construction, the receiving body and the thread restraint plate can be manufactured from an integral casting, and the receiving body does not serve as the sliding surface for the thread, but the ring insertable into this receiving body serves. Therefore, it is possible to omit the deburring, which takes time and labor for the opening of the receiving body. These rings can be produced very simply and without flash. The interchangeable provision of the ring offers the advantage that another ring of different material and different diameter can be substituted if required for the type and thickness of the thread.

The fact that the annulus is engageable with the receiving body provides a quick connection between the annulus and the receiving body. Thus, the ring can be inserted into the receiving body through the opening in the thread stop plate, the opening being at least partially covered by the thread guide arm after the thread stop plate is attached to the thread guide arm. The introduction of the ring from the rear side of the thread restraint plate into the receiving body enables the automatic mounting of the ring on the member. The thread stop plate can then be screwed onto the thread path arm, for example. By partially covering the opening with the thread arm,
The ring can be prevented from coming off the acceptor by itself.

The ring can be made from a different material than the receiver or the thread restraint plate. In order to adapt the thread arm to threads of different types and thicknesses, it is only necessary to use rings of different materials, all other elements of the thread arm being conventional. Ceramic, plastic or metal is used as the material of the ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of a thread guide member for a thread guide arm will be described below with reference to the drawings. FIG. 1 shows a thread stop plate 10 having a substantially circular edge. On this thread stopper plate 10, the ring 1
Thread guide members 11, 1 formed by a star-shaped receiving body 14 having six receiving notches 15 (FIG. 3) in each arm.
2 and 13 are provided. The receiving body 14 has a central hole 17 into which it is screwed to connect it to the thread guide arm.

As can be seen in FIG. 2, the thread restraint plate 10 has a ring 16 under each arm of the receiver 14.
It has an opening 18 for introducing into the notch 15 of 4. The shape of the opening 18 is matched with the shape of the ring 16.
FIG. 3 shows a cross section of the thread guide member 11. As can be seen, the ring 16 fits into the notch 15 in the receiving body 14. The annulus 16 has a central opening 19 for threading. The ring 16 is fixed in the notch 15 by two engaging protrusions 20 provided in the notch 15.
These engagement projections 20 engage into recesses 21 (FIG. 4) formed at right angles to the circumferential direction of the ring 16 to form an engagement connection which is easily re-engaged, whereby the ring 16 is released. Are provided on the receiving body 14 so that they can be easily replaced. The central opening 19 of the annulus 16 has a cross section that extends outwards from the inside on both sides. This makes it possible to avoid sharp ridges that would result in large yarn wear. The outer diameter also extends outward on both sides, ending in ridges 22 and 23. A small diameter area 24 is provided in between, and a protruding area in the notch 15 of the receiving body 14 engages with this area 24, preventing the ring 16 from axially disengaging from the notch 15. Accordingly, after the thread stopper plate 10 is screwed onto the thread guide arm that covers at least a part of the opening 18 of the thread stopper plate 10 from the rear side, the ring 16 cannot unintentionally drop from the receiving body 14 by itself. impossible. When replacing the ring 16 with another ring or a ring made of a different material or with a different diameter, the thread stop plate 1
0 is simply removed again from the thread arm and the ring 16 is disengaged by a tool that fits into the central opening 19 and is removed from the receiving body 14 through the opening 18 and subsequently a new ring is received. The notch 15 is engaged.
