Abstract

According to the invention, the reinforcement of disc separators (1) in ring spinners against wear of the edges (3, 5) thereof hit by the ends of broken threads may be simplified, whereby said edges are protected by metal deflector bars (8) which may be clipped or otherwise easily fitted to the disc separators, or which may be exchanged upon wearing out or being damaged.

Description

The demarcation strip that is made of plastics of ring spinner

The present invention relates to a kind of demarcation strip that is made of plastics that is used for ring spinner, have the wear-resisting protection department of its preceding arris at least.

Most of ring spinners are provided with demarcation strip, and they are arranged on the height of the cop on the ring rail between the spindle.Their task is: stop the ballooning of yarn of heaving sometimes of adjacent yarning position to contact and the broken yarn end is thrown in the adjacent ballooning of yarn.This can cause the broken yarn on the ballooning of yarn of this adjacency, and they may develop into serial broken yarn.

At present big multistage being made of plastics of demarcation strip.After broken yarn takes place, often the yarn end on the cop is thrown on the front of demarcation strip or the back and when cop rotates, strained by arris.This yarn that synthetic material is especially made is cut in the plastics arris of demarcation strip and goes and make it to damage.Such damage is tended to catch the loose thread that flies hair or incision and itself may be become the reason of further broken yarn.

In order to stop this situation, open (Japanese publication number 10204732A) makes the front of this demarcation strip that is made of plastics and back arris be provided with metal system protection sleeve.Arris becomes the convex thickening for this purpose.Pushed to the metal sleeve of trough of belt on projection, they are fixed on the projection owing to flexible.

This arrangement requirement has little tolerance and elastic metallic sleeve between projection and metal sleeve.They are precondition with the straight flange rib also, and sleeve can be pulled on this arris, and have therefore limited the possibility of the moulding best of demarcation strip.

Thereby task of the present invention is that suggestion proposes a kind of more simply and freely solution.It has comprised in the characteristics described in the characteristic of main claim.Because the deflection bow is arranged in the arris front of demarcation strip, arris is moulding at random, and is especially crooked.Deflection bow can be fixed on the replacing that makes on the demarcation strip when wearing and tearing or damage mounting board, and it is easier.The different designs scheme and the flexible program that makes it to be fixed on the demarcation strip of deflection bow have been described in the dependent claims.

Embodiments of the invention have simply been represented in the accompanying drawings.Be depicted as:

Fig. 1: the stereogram of first kind of form of implementation;

Fig. 2: the view that is similar to Fig. 1 of second kind of form of implementation;

The view that is similar to Fig. 1 and Fig. 2 of Fig. 3 and 4: two kinds of other forms of implementation;

Fig. 5: the partial view of pressing a kind of flexible program of form of implementation shown in Figure 4;

Fig. 6: the sectional view in Fig. 4 A-A plane.

Accompanying drawing has been represented a kind of demarcation strip 1, and its face 2 is at its preceding arris 3, its bottom edge 4 and strengthen by projection 6 on the part of arris 5 thereafter.Demarcation strip is extended with the bearing 7 of an eyelet-like in its rear face position, and it can be clamped on a fixed bar of not expressing by means of this bearing.

Demarcation strip 1 is furnished with deflection bow 8 on the part of its preceding arris 3 in the form of implementation shown in Fig. 1 and 2, it by two be parallel to each other by metal wire rod, especially the branch 9,10 of being made by steel wire forms.Two branches 9,10 of wire rod bow interconnect by an eyelet 11, and this eyelet mounting board is on a hitching post 12 on the base 4 of demarcation strip 1.Play two branches therefrom and extend upward along the preceding arris 3 of demarcation strip, there they two form eyelet 13 again, they enclose with eyelet and block hitching post 14, hitching post is stretched from mutual opposed the both sides on the surface 2 of demarcation strip.

Hitching post 12 is used as the supporting of demarcation strip 1 on ring rail simultaneously and therefore fixes the tram of demarcation strip.

To hitching post 12, to hitching post 14, go the bow of deflection afterwards 8 just to be fixed on the demarcation strip at eyelet 11 mounting boards with eyelet 13 mounting boards.Hitching post can be provided with flat end projection, and they are with eyelet 11 or 13 fixed bits.The deflection bow can easily unload and change with another from hitching post 12 and 14 again.

The shape of design deflection bow 8 makes it be positioned at the front of the preceding arris 3 of demarcation strip 1 with a little distance in embodiment illustrated in fig. 2.

As seen from Figure 3, deflection bow 8 ' also can be made up of the wire rod bow of a list, and it can be inserted in the preceding arris 3 of demarcation strip 1 or/and 15,16 li in the hole of 6 li of the projectioies of bottom edge 4.The deflection bow of this pattern has only a branch, but can alternatively have eyelet, and it can be clamped on the hitching post of demarcation strip 1 by this eyelet.

Fig. 4 has represented a kind of form of implementation, and wherein deflection bow 8 " to form by the lath of a respective curved, unlimited or blind bore eye stretches out this lath with one in its lower end, can clamp on hitching post 12 by the eyelet lath.Lath has one and rolls 17 in the top, and it can be inserted into from the limit 18 li of vacancies of 6 li of the projectioies of the preceding arris 3 of demarcation strip 1.

The deflection shown in Figure 4 bow of in the enforcement flexible program shown in Fig. 5 and 6, making 8 by plate " in its lower end with all have geometrical clamp 19 at an upper portion thereof, it can be clamped on the projection 6 of demarcation strip 1 by means of geometrical clamp.

Self-evident,

deflection bow

8,8 ', 8 ", if it has the wire rod bow of two branches or be made up of a lath by the wire rod of list or by one, can also be fixed on the demarcation strip 1 in other very different mode.It for example also can be with screw threads for fastening on demarcation strip so, also can will be described make up and is favourable in some cases in the fixedly pattern of lower end that deflection is bent and upper end.

As shown in detail like that, the back arris 5 of demarcation strip 1 also can be provided with a deflection bow.
