摘要： A shuttle embroidery machine having a shuttle guide has, for each embroidery position, a rear-side driver nail (11, 11') and a front-side driver nail (9, 9') for guiding a shuttle (5). The embroidery machine comprises, at each embroidery position, a shuttle race (3) and the shuttle (5) comprises a shuttle thread for embroidering. At the rear end (16) of the shuttle (5), a magnet (37) is fitted in a region on which the rear-side driver nail (11) acts. The rear-side driver nail (11) contains a magnet (35) or a ferromagnetic material, wherein the magnet (37) and the rear-side driver nail (11) have the same polarity, such that the shuttle (5) is repelled by the rear-side driver nail (11).

摘要： The invention relates to the device for reducing vibrations of sewing machines induced by dynamic forces of the crank mechanism of needle bar (16) and the thread feeder (14) mechanism. At the same time the crank mechanism of needle bar (16) is coupled with the balancing eccentric mechanism (19), whose exit member (193) has a lift several times lower than the lift of needle bar (16), and its weight is several times higher than the weight of moving parts of the crank mechanism of the needle bar (16) and of the thread feeder (14) mechanism. The vertical component of speed vector of exit member (193) of the balancing eccentric mechanism (19) has an opposite sense with respect to the speed vector of needle bar (16).

摘要： The invention relates to a sewing machine which comprises a stationary sleeve (41) enclosing an oscillating shaft (38) in order to dampen the torsional oscillations of the latter. Between the shaft (38) and the sleeve (41) a gap (43) is configured. Said gap (43) is filled with a viscous substance (24) and is closed by sealing elements (44). When the shaft (38) is moved relative the sleeve (41) a viscous friction occurs in the viscous substance and brings about a damping effect.

摘要： A bottom and top feed sewing machine includes a feed dog and a top feed foot which contact a workpiece on a throat plate from below and above respectively to perform a feeding operation, a bottom side back-and-forth feed mechanism which drives the feed dog back and forth, a bottom side up-and-down feed mechanism which drives the feed dog up and down, a top side back-and-forth feed mechanism which drives the top feed foot back and forth, and a top side up-and-down feed mechanism which drives the top feed foot in an up and down direction. The top side up-and-down feed mechanism includes a cam mechanism which takes out a reciprocating movement from a rotational movement of a rotary shaft which performs a rotational drive. The cam mechanism includes a triangular cam having an outer circumference, a shape of which is obtained by connecting two kinds of circular arcs, each of three vertices of an equilateral triangle being a center of small and large circular arcs, and a cam follower having receiving surfaces which hold the triangular cam therebetween. The triangular cam is fixed and supported on the rotary shaft so as to rotate around a position, which is on a perpendicular line drawn down to a base from one of the vertices and is closer to the base than the center of the equilateral triangle is, and such that, when a needle bar which performs stitching by an up-and-down movement is located at the upper dead point of the up-and-down movement, the top feed foot is located at the upper dead point of the reciprocating movement along the up-and-down direction.
