摘要:
A device for mechanically producing folded hems on the end edges of a piece of cloth detached from a length of fabric, and comprising(a) means for folding the forward end edge of the fabric, corresponding to the folded-in part of the hem to be, over the edge of a delivery member,(b) a gripper arranged on a coiler plate, which is advanced to the delivery edge to grip the fold of the fabric thus that the folded-in part is pressed to contact against the fabric,(c) means for rotating the coiler plate and the fabric fixed therto substantially half a turn, thus that at least a part of the width of the hem to be, is located on a second conveyor track for feeding the piece of cloth to a sewing machine,(d) a holding device pressing the hem against the second conveyor track, while the coiler plate is pulled out of the hem, and(e) an arresting device pressing an inner portion of the fabric against a first track and the delivery member a piece of cloth is detached, each one of the end edges of said piece of cloth which are located on the conveyor tracks being fed towards a sewing machine each. By making the gripper displaceable within the coiler plate's plane the width of one of the hems can easily by adjusted.

A fabric workpiece is laid right side up on a flat table adjacent and transverse to the bed of a dart-forming sewing machine. A predetermined location on the workpiece is positioned over an aparture in the table in line with the bed and a folding element comprising a row of needles projecting from a reciprocal bar is pushed against the workpiece at the aperture and through this aperture to form a fold in the workpiece and displace this fold to the stitching location of the sewing machine. The table extends at an angle of approximately 75* to the bed of the sewing machine and is provided to each side of the aperture slot with an elastic lip formed by a coil spring that serves to guide and hold the fold.

A take-up rail assembly including a fixed idler rail and a longitudinally movable take-up rail. The fixed idler rail is attached to a quilting frame or other sewing frame and the position of the fixed idler rail may be longitudinally and vertically adjustable with respect to the sewing frame. The take-up rail is movably attached to the sewing frame and a take-up rail control mechanism moves the take up rail longitudinally forward and rearward with respect to the fixed idler rail as the sewing machine moves with respect to the sewing frame, thus providing full utilization of the throat length of the sewing machine.
摘要:
A sewing device (1) is provided with a programmable electronic control system (4) for sewing folds and tucks. Such that format-dependent parts (guide tongue, pressure pad) can be eliminated at the time of a change of the seam program the use of a guide tongue is eliminated that depends on the form of the seam and of a format-dependent pressure pad. The feed of the fabric is performed only with a folding tool (5) with straight folding edge and the holding and guiding of the fabric during the sewing operation using a straight pressure pad (7). The electronic control system (4) can be programmed such that the desired seam course is obtained exclusively by the superimposition of longitudinal and transverse movements of the pressure pad (7). Parameters (1′-7IV) that determine the seam course are preferably entered in a graphics-supported manner.
摘要:
An automatic sewing machine comprises a folding device and a guiding and feeding device for a folded workpiece and a main workpiece on which to sew the folded workpiece. The folding device comprises an outer frame with creasing modules which have folding bars. The creasing modules are mounted on the outer frame in a manner adjustable in their direction of extraction and approximately crosswise thereto.

A folding device is provided for an automatic sewing machine for folding over at least two edge strips of a first fabric part. The edge strips extend at an angle to one another and the first fabric part will be sewn on a second fabric part. The device includes a support plate for the second fabric part, a folding plate movable in relation to the support plate for the first fabric part, and a carrier plate. The carrier plate is movable in relation to the support plate and the folding plate for a pressing plate that can be placed on the first fabric part. At least two folding slides are provided which are arranged at an angle in relation to one another and which are connected to a drive means each. The folding plate and the pressing plate have at least one edge strip each, whose angle is adjustable, and the angle of at least one of the folding slides is adjustable.
