One end of the first part is provided with an entering end the second part (2) is provided with a cam for connection with the second part (2) is provided with a cam for connection with the second part (2) formed by a hollow body provided with a bilaterally coincident cam. The thrid part (3) is provided with a through-hole and a shoulder towards the second part (2).

Description: G DEVICE FOR CORDS Technical Field The technics solution concerns heald and cord tying-up conecting device applicable for all tying-up types. Background Art For heald and cord tying-up connection there is used so far a coupling with polyolefϊn 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 fhctional resistance. Disclosure of invention 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. 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 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 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. The device according lυ tile lec nicai solution is operated in such a way that the iiist part i 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: C L A I M S 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).
