Abstract: The invention relates to a device for electrically conductive connecting, by means of ultrasonic welding, of first electric conductors (140, 142) and second electric conductors (144, 146) in a compression space the cross section of which can be changed and which comprises at least one lateral slide, a sonotrode and a counter electrode, wherein firstly, blank ends of the first electric conductors (140, 142) are introduced into the compression space and are welded by means of ultrasonic action to form a first connection (148) and then after the first connection has been removed from the compression space, blank ends of the second electric conductors (144, 146) are introduced into same and are welded by means of ultrasonic action to form a second connection, wherein the first connection is fed to a retaining device (182, 184) before the second connection is welded.

Abstract: A device (40) and a method is described for handling fragments (10) of a broken needle (11), for example in the context of a needle exchange of a broken needle (11) for a new needle (17). The fragments (10) of the broken needle (11) are arranged in a container (16) in a predetermined position. An image (32) of the fragments (10) of the broken needle (11) is then recorded with the aid of a camera (23). The recorded image (32) is stored for documentation (32) at at least one storage location and/or analysed as to whether all the fragments (10) of the broken needle (11) are present. After recording the image (32), the container (16) is closed in order to avoid the fragments (10) of the needle (11) being lost away from the sewing workstation.

Abstract: Quality assurance in sewing a textile sewn sequentially in a plurality of workstations (11) can be provided using a carriage 14 that can be moved between the workstations (11). Should a needle (12) break off in a workstation (11), the carriage (14) is moved to this workstation (11). The fragments (13) of the needle (12) are arranged in the container (20) and once it has been established that all the fragments (13) have been removed from the workstation (11) a replacement needle is provided for this workstation. The container (20) has an accommodation space (21) delimited by a main body (22) and a lid (23). A retaining magnet (34) is arranged in the region of a base (32) of the main body (22) extending along one axis (A) to retain magnetizable fragments (13) of a needle (12).
