Claims

[Claims for Utility Model Registration] 1. A hollow needle bar is provided with a carrying means and a holding means, and this hollow needle bar is formed as a pressurized medium cylinder capable of being loaded in both directions, and furthermore, a multi-needle type - selective activation of the needle bar in such a way that the sewing machine is driven by a positioning drive and in this multi-needle type - a positioning member rigidly connected to the arm of the sewing machine determines the rotational speed and positioning of the needle bar in a predetermined position; In the switching device for a multi-needle sewing machine and for stop switching, the switching device includes a carrier 2, which is rigidly connected to the arm 1, and a carrier 2, which is rigidly connected to this carrier but whose position can be changed. It consists of two electromagnets 3, 4 and two lever transmissions 6, 7 of almost identical construction which are pivotably supported on a shaft 5 present in the carrier 2, in this case the electromagnets 3, Lever transmission mechanism 6 driven by 4
, 7 against the action of the spring 8 can be limited by an adjustable abutment material 9 in each case, and in this state the respective lever transmission 6 .
7 is configured such that it can be occasionally locked by a switching pawl 11 supported by an abutting portion 10 fixed to the machine frame. 2 An adjustable angle member 12 on the carrier 2 that buffers the end positions of the electromagnets 3 and 4 with two rubber pads 13.
The device according to claim 1 of the utility model registration claim, wherein: is fixed. 3. Each lever transmission mechanism 6, 7 consists of a swinging lever 14, 15 and a two-armed lever 16, 17, each of which is supported in parallel on the shaft 5, and the swinging lever 14 and lever 16 are The device according to claim 1, wherein the swinging lever 15 and the lever 17 are integrally connected to each other via a spring 18 via a spring 19. 4 Rotatable roller 2 on each swing lever 14, 15
0 as well as a strapping surface 21 and another strapping surface 22. 5. One arm of the lever 16.17 receives a pivotably mounted switching pawl 11, and the pivot lever 14.
15 is configured to abut against the switching pawl 11 under the action of a spring 23, and the lever 16.
17, the other arm of which accommodates a switching rod 24 articulated in a height-adjustable manner. The device described in.
