Abstract: The method for the manufacture of multilayer connecting substrates with multiple functions comprises the design of the connecting substrate taking place in functionally separated manner, in that signal conducting substrate parts (19), power supplying substrate parts (2), mechanical substrate parts (7), as well as the arrangement of components (4) or component-carrying substrate parts is separately planned and optimized as independent functions or modules and finally associated with spatially separated functional areas (inner/outer) of the overall circuit, the design taking place by the connection of the modules to an overall circuit embodying the connecting substrate. The resulting multilayer circuit with conductor network (19, 2), components (4) and mechanical stiffening elements (7) has the following structure.

Abstract: A sewing unit comprises a sewing machine having a guide device for a binding. A controlled positionable guide member of the guide device makes it possible to sew a binding on an endless edge of a workpiece portion by means of a plurality of separately sewing seams.

Abstract: A workpiece guide device on a sewing machine serves for the automatically controlled alignment of a workpiece, with respect to its edge, for the purpose of sewing along the edge of the workpiece at the correct distance from that edge. The circumferential side of a motor-driven guide wheel (36) carries wheels (34) which are likewise motor-driven and which guide the workpiece transversely to the direction prescribed by the guide wheel (36).

Abstract: For the production of circular seams with overlapped ends on a workpiece, a sewing machine driven in a controlled manner and provided with a marker for applying a mark, and a sensor for detecting the mark after marking the workpiece with a mark. The workpiece is sewn until the mark is effectively detected by the sensor which is disposed in a predetermined relationship to the marker, and thus initiates a control operation which initiates the end of the sewing operation in dependence upon a particular number of oversewn stitches. The mark may be applied and detected on the work material in one operating cycle. Thus, for example, circular workpiece openings may be sewn in such a way that the seam end is matched to the start of the seam in spite of different diameters of the work piece opening.

Abstract: In a trimming device for cutting a cover thread (30) on a multiple needle chainstitch sewing machine, a moveable thread catcher (15) picks up the cover thread (30), which runs between the cover thread guide (27) and a hook part (29) on the spreader (28), and presses the cover thread (30) towards a trapping and cutting device (49,51,48,40) of the trimming device which is disposed adjacent to the left-hand sewing needle (23).

Abstract: A feed dog drive having an adjustable feed direction for a sewing machine having, a needle plate, a presser foot, and a feed dog element. The drive has a device for carrying out a feeding and lifting motion of the feed dog element, a holder, and a device for rotatably mounting the feed dog element on the holder such that it can be turned is synchronism with stitch formation of the sewing machine.

Abstract: A drive device for a reciprocating part having a part which is connected to a stepping motor whose direction of rotation can be changed. The stepping motor is reciprocatingly actuated in a single step length between no more than two step positions, such that it is possible to move the reciprocating part backwards and forwards in a predetermined manner in a simple and reliable way.

Abstract: A device for the automatic formation and sewing of a hem at a continuous edge of an opening of variable width in a workpiece, a hem-forming device on a sewing machine which is controlled by a logic device. An actual force acting upon a guide body is compared with at least one desired force preselectably stored in the logic device. In the event of a difference between these forces, an adjusting device actuates the guide body, serving as a cloth tensioner, until an actual force corresponding to the desired force is established on the guide body.

Abstract: A sewing machine for the controlled sewing on of a tape from a tape supply onto a tubular edge region of an elastic workpiece thus forming a band, which is provided with an additional feed dog in front of the usual feed dog in the region of the needle plate. The additional feed dog is driven by a stepping motor transversely with respect to the workpiece feed direction and is used to guide and align the workpiece. Sensors control the alignment movement of the workpiece.

Abstract: A trimming device for trimming a top cover thread from a workpiece on a multiple needle sewing machine having a thread catching device which is movable between a counter-plate and a knife. In operation the top cover thread is picked up by the thread catching device between a workpiece and a top cover thread guide. A top cover thread trap serves as a counter-plate for the thread catching device. The knife is attached to the counter plate with a gap therebetween, with the thread catching device being swingable within said gap.

Abstract: An alignment device for the automatic adjustment of the edge of a tubular workpiece to be sewn on a sewing machine having, a presser foot, a feed dog operating on the presser foot, a sensing device for detecting the edge of the workpiece, and a guide member disposed on a side of the feed dog. The alignment device has a device for rotatably driving the guide member, and a device responsive to the sensing device for controlling the equatorial or peripheral speed of the guide member relative to the sewing speed of the sewing machine.

Abstract: A thread break detector for a thread in a sewing machine comprising, a sensor device having a signal path cross section for scanning, a first thread guide disposed on one side of the sensor device, and a second thread guide disposed on the other side of the sensor device and being movable in synchronism with the stitch formation of the sewing machine, such that the second thread guide deflects the thread in the region of the sensor device a greater amount than the cross section of the sensor device signal path.

Abstract: A workpiece controlling device for a sewing machine comprising, a workpiece feed mechanism which feeds material in a substantially straight line, an alignment device disposed immediately in advance of the point of stitch formation in the region of a needle plate, a device for moving the alignment device transversely relative to the direction of material feed in the sewing machine, with the alignment device acting on the workpiece in synchronism with the stitch formation, and a device for controlling the transverse motion of the alignment device.

Abstract: This invention relates to a stacker mechanism for removing flexible work pieces from the working area of a machine. The stacker mechanism of the present invention includes a frame, an arm, and a support member having first and second pivotal connections. The first pivotal connection serves to rotatably secure the support member to the frame and allows the arm carried thereby to be vertically rotated. The second pivotal connection allows pivotal movement of the arm in a horizontal direction. The end of the arm opposite the second pivotal connection carries a wiper mechanism for engaging and moving the work piece. A driver is employed for pivotally moving the arm. A motion retarding assembly is provided at the second pivotal connection for applying frictional restraint to the horizontal turning movement of the arm whereby a higher coefficient of friction is maintained at the second pivotal connection relative the first pivotal connection.
