The thrid part (3) is provided with a through-hole and a shoulder towards the second part (2).

Description

TECHNICAL FIELD

[0001] The technics solution concerns heald and cord tying-up conecting device applicable for all tying-up types.

BACKGROUND ART

[0002] For heald and cord tying-up connection there is used so far a coupling with polyolefin injection which enables only an unidirectional connection securing. There has been checked in effect that this securing is unprofitable as a disconnection in case of a return motion or buffing of adjoining couplings during weaving car occur. The used material of this connection does not guarantee the required frictional resistance.

DISCLOSURE OF INVENTION

[0003] The above-mentioned deficiences have been removed by the heald and cord tying-up connecting device in accordance with this technical solution, the substance of which consists of three parts. The first part is provided with a groove which enables its putting on the heald and consequently a motion along the heald. One end of the first part is provided with an entering end, another with a cam for connection with the second part. The second part is formed by a hollow body with a bilaterally congruent cam. The third part coincides in form with the first part and has, in addition, a through-hole for the cord tying device and a shoulder towards the second part for a fixed bilateral closing of the complete connection.

[0004] The device in accordance with this technical solution is universal and can be used in practice for all types of tying-up. Its most important advantage is that all parts are takable independently which has not been known so far with any device for the given purpose. A bilateral securing connection between heald and cord tying device has not been solved anywhere to date as well. All parts being made of a high-resistant rub-proof plastic, the new product has a long service life even with a high speed of the weaving machine. A further substantial advantage of this device is saving of two operations which increases productiveness and reduces laboriousness.

BRIEF DESCRIPTION OF DRAWINGS

[0005] The technical solution is further more detailed explained by means of a drawing where FIG. 1 illustrates a device when all three parts are connected and both the heald and cord tying-up device are fixed, FIG. 2 illustrates the first part provided with a groove, FIG. 3 is a hollow body with a bilaterally congruent cam and FIG. 4 illustrates the third part with a through-hole.

MODE FOR CARRYING OUT THE INVENTION

[0006] The device in accordance with the figure consists of three parts. The first part is provided with a groove which enables to put it on the heald 5. One end of the first part 1 is provided with an entering end and another with a cam. The second part 2 is formed by a hollow body with a bilaterally congruent cam. The third part 3 coincides in form with the first part 1 and has, in addition, a through-hole for the cord tying-up 4 and a shoulder towards the second part 2.

[0007] The device according to the technical solution is operated in such a way that the first part 1 having been put on the heald 5 is connected with the cap second part 2 yet before levelling in phase of preparation. In this way a sliding motion along the heald 5 is enabled. During the assembly the third part 3 is slided on the cord tying-up device 4. The cord tying-up device 4 having been passed through the heald's 5 eye and alignement into the right levelling position, the cord's remnant is cut off. Owing to the semi-assemblys slliping from parts 1 and 2 upwards, the heald 5 and the cord tying-up device 4 in the second part 2 are firmly clamped which prevents from picking-up or slippage of the cord tying-up device 4 in the heald 5. A motion of the third part 3 towards the second part 2 causes a perfect camming of the whole connection with a bilateral counter-motion locking.

Claims

1. Heald (5) and cord tying-up connecting device (4) designated so that it consists of the first part (1) provided with a groove, one end of the first part (1) being provided with an entering end of the first part (1) with a cam, by means of which it is interconnected with the second part (2) formed by a hollow body provided with a bilaterally coincident cam, meanwhile the third part (3) is provided with a through-hole and a shoulder towards the second part (2).
