摘要： Sequin strip (60), let out from a reel and then placed on the upper surface of a supporting plate (8), is fed at a predetermined pitch corresponding to a size of a sequin (S') of the strip. After a sewing needle (31) fits into a hole (61) of a leading sequin (S') as a needle bar (31) descends in accordance with sewing operation, a movable cutter blade cuts off the leading sequin (S') by being driven downward by abutment against the needle bar (31) or a member (32) movable with the needle bar (31). Sequin-cutting portion (27a) of the movable cutter blade (27) has a thickness smaller than a thickness of an abutting portion (27b) that abuts against the needle bar (31) or the member (32) movable with the needle bar (31), to secure an appropriate strength. For example, the movable cutter blade (27) is shaped such that the thickness of a particular region, corresponding to a needle drop position, of the movable cutter blade (27) is reduced, and that, when the movable cutter blade (27) is in a posture before abutting against the needle bar (31) or the member (32) movable with the needle bar, an upper region (u) of the thickness-reduced sequin-cutting portion (27a) is located below an uppermost region (T) of the abutting portion (27b) not reduced in thickness.

摘要： A needle bar drive apparatus for a sewing machine includes a dedicated drive source (16) for driving a needle bar (3) of the sewing machine to move up and down. When a sewing operation is to be performed, a control section (160) controls the drive source to cause the needle bar to move up and down within a predetermined stroke range, but, when no sewing operation is to be performed, the control section controls the drive source to cause the needle bar to retreat to a predetermined evacuation position set above a top dead center in the predetermined stroke range. The control section is also capable of varying a timewise pattern of the upward and downward movement of the needle bar within the predetermined stroke range. Thus, it is possible to secure an increased space between the lower end of the needle bar and the upper surface of a sewing machine table (6) during a non-sewing period while limiting the stroke of the needle bar to a necessary minimum during a sewing period. Also, timing for driving the needle bar can be varied freely.

摘要： An embroidery sewing machine with such a structure that at least one of driving mechanisms required for embroidery sewing is provided with a driving source independant of the other driving mechanisms and a control device is provided so as to control said one driving source and those of the other driving mechanisms for synchronous operation thereof. With this structure, the driving mechanism having the independent driving source can structurally be simplified thanks to the reduced number of interlocking mechanisms and thus vibration and noise can be reduced. Further, a timing at which to operate the driving mechanism having the independant driving source can freely be set by a signal from said control device according to an embroidery pattern.

摘要： Chain-stitch sewing machine includes: a looper provided under a needle plate and having a thread lead-in port and thread lead-out port, the looper being rotationally driven in synchronism with a sewing operation; a plurality of thread feed ports connecting to different thread supply sources; and a connecting member having a thread passage, the connecting member selectively connecting any one of the plurality of thread feed ports to the thread insertion port of the looper via the thread passage. Threading mechanism passes the sewing thread, fed via the thread feed port connected by the connecting member to the thread insertion port of the looper, into the thread insertion port and causes the sewing thread to be taken out via the inserted thread lead-out port of the looper.
