Abstract: In an apparatus for separating parts arranged for example in at least two adjacent rows and including a transfer device, which is provided with at least two holding elements which pick up the parts in a first position and deposit them in a second position 5b, guide tracks are provided by which the distance at which the holding elements are disposed adjacent one another is changeable during the transport of the parts from the first position to the second position.

Abstract: A drive mechanism for a sewing machine, for example an embroidery unit (10), has a holder for material to be sewn, which is attached to an arm carriage (20) which is displaceable on an arm (19), wherein the arm for its part is displaceable on a support carriage (16) perpendicularly in respect to the arm carriage (20). The bulky size is disadvantageous in connection with known support-arm constructions. To avoid this it is proposed to design the arm to be pivotable around a joint (18) into a position of rest, in which the arm (19) and the support (14) extend essentially parallel with each other.

Abstract: To embroider combination patterns composed of partial patterns on sewing or embroidering machines with a driven embroidery frame, a common sewing stitch each, which is used as a hooking point, is located outside the contour of the pattern, and whose connection threads to the pattern proper are removed after finishing the second partial pattern, is formed at the end of the first partial pattern and at the beginning of the second partial pattern for the exact positioning of the partial patterns.

Abstract: An embroidery frame, comprising a closed inner frame and an outer frame open at a point and a clamping device provided on the outer frame with one laterally projecting projection each at each of the two ends of the outer frame. A stud is provided that can be fixed at one projection and a screwing device is provided that cooperates with the stud and is supported at the other projection. The stud is displaceably guided within one projection at a closely spaced location from the outside of the frame and is supported with a head on a stop face of the projection. The other end of the stud is rigidly connected to a sliding block, which is longitudinally displaceably accommodated within a guide provided in the other projection. A tie rod is led out of the other projection extending obliquely toward the outside of the frame. The tie rod is pivotably arranged at the sliding block.

Abstract: A device is provided for detachably fastening an embroidery frame, slidingly arranged on a support surface, to a drive member of a feed mechanism of a sewing or embroidery machine. The device includes a coupling device acting in a positive-locking manner and nonpositively acting locking device. Two coupling pins, which are located at mutually spaced locations from one another in the horizontal direction and carry a head each, are fastened to the said embroidery frame. A holding element is fastened to the drive member and contains two elongated holes, which extend in parallel to the said support surface of the machine and whose height corresponds to the diameter of the said coupling pins. A free space is provided in the area of the elongated holes for the heads of the said coupling pins.
