ABSTRACT:
The present invention relates to a device for displacing the color-change carriage on multiple-head embroidery machines having a plurality of embroidery needles per head which can be coupled alternatively with the needle bar drive for change in color or thread, the needle bar carriers of all embroidery heads being laterally displaceable jointly by a displacement bar which is connected with the color-change carriage. In order to create a dependably operating as well as easily mounted displacement device with the use of only a few individual parts, a control bar (10) which is provided in rack-like manner with incisions (10a) is arranged on the color-change carriage (6), a crank pin (11) driven by a servomotor engaging in said incisions (10a) and upon its engagement in an incision (10a) swinging a locking lever (12) on which there is arranged a locking member (14) which cooperates with the incisions (10a) and, via the control bar (10) positions the color-change carriage (6) in its corresponding position. The incisions (10a) for the crank pin ( 11) and for the locking member (14) can be of identical development and be provided with funnel-shaped bevels (10b).
