摘要： A drive means for feeding a material to be sewn on a sewing machine (1) includes a feed dog (7) to be coupled to a continuous rotary drive (9) via at least one intermediate drive. To achieve optimum drive conditions in a comparatively simple way, the intermediate drive consists of a belt drive (10) with a belt (13) circulating around a drive wheel (11) and a driven wheel (12), where the belt (13) having an excess length is guided over a control roller (14) at the working portion thereof (131) and over a tension roller (15) at the return portion (132) thereof, and the control roller (14) and the tension roller (15) are mounted so as to be periodically reciprocated in the sense of a release or deflection of the belt (13) for decelerating, stopping and accelerating the rotation of the driven wheel, and the driven wheel (12) is in rotary connection with a feed dog (7) designed as circular conveyor, in particular as conveyor belt (20).

摘要： A sewing machine is described with a sewing needle drive (4) and a forward feed drive for the garment, comprising a continuous rotational drive (9), a belt conveyor (7) for the garment and an intermediate drive (10) with two gearwheels disposed between the rotational drive (9) and the belt conveyor (7), of which the gearwheel on the driven side can be twisted relative to the one on the drive side with over-feed or underfeed by means of a control lever (14) driven by an eccentric drive (15) depending on the sewing needle drive (4). In order to provide advantageous construction conditions it is proposed that the two gearwheels are arranged as mutually combing gearwheels (11, 12), of which the one on the driven side is held in a fixed link (13) rotationally held about the axis of the gearwheel (11) on the drive side, on which the control lever (14) acts.

摘要： An automated circular sewing machine system for attaching an elastic band to a tubular body of fabric or simply forming and sewing a hem thereon. The system includes, among other things, a sewing head which is located between a pair of elongated work holding roller assemblies which project outwardly on either side of the sewing head. The roller assemblies include a front or feed side roller assembly and a rear or drive and tensioning roller assembly. The front roller assembly is free wheeling and is fixed in position relative to the sewing head. The drive and tensioning roller assembly includes a movable drive and tensioning roller driven by a motor and consisting of a solid unitary member which is generally cylindrical with a rounded outer nose portion and an inner fabric support surface. The entire drive and tensioning roller assembly is pre-positioned by a laterally movable clamping plate assembly to a fixed position relative to the sewing head depending on the size of the tubular body being sewn. The drive and tensioning roller is thereafter moved, i.e. rotated, away from a generally vertical "home" position a predetermined distance from the sewing head and front roller assembly by a pneumatically activated piston to tension to the member or members being sewn prior to and during a sewing operation. After the sewing operation is completed and prior to an unloading operation, the drive and tensioning roller is returned to its home position also under control of the pneumatic piston.

摘要： A button-sewing machine (1) comprises a needlebar frame (6), which is suspended like a pendulum and connected to a rocking linkage (8). A button-holding clamp (5) is tiltably mounted in a stand (4), which is carried by a base plate (3), which is mounted on the machine base (2) and longitudinally displaceable relative to said machine base and longitudinally reciprocable by an actuating head (9). The latter is operatively connected to the main shaft of the machine.The machine can be used to perform several different working programs without an alteration of the machine. For this purpose the stand (4) is transversely movable relative to the baseplate (3) or the baseplate (3) is adapted to perform relative to the machine base (2) not only a longitudinal displacement but also a transverse angular movement. A coupling element (19) is provided, which is operable to selectively couple the actuating head (9) either to the baseplate (3) or to the rocking linkage (8) of the needlebar frame (6). Separate positioning drives (22, 23, 28) are provided for displacing the stand (4) or for imparting a transverse angular movement to the baseplate (3), for tilting the button-holding clamp (5) and for actuating the coupling element (19). These positioning drives are adapted to be energized and de-energized in response to the number of revolutions of the mainshaft of the machine or the number of stitches. Said numbers can be determined by control programs.

摘要： An attachment (4) for sewing machines (1) for trimming the material to be sewn has a cutting tool comprising a blade (5) and a counter blade (6), which can be driven in dependence on the intermittent feed of the material to be sewn, and whose cutting plane (S) is aligned parallel to the feed. To achieve an inexpensive, space-saving and safe cutting of the material to be sewn, the cutting tool has a rotary blade (5) to be driven around an axis of rotation (D) normal to the cutting plane (S), which forms at least one cutting edge (7) extending only over part of the blade periphery and along its course deviates from a circular arc around the axis of rotation (D), and which rotates with a number of revolutions adapted to the feed of the material to be sewn indirectly proportional to the number of cutting edges.
