摘要： An overlock sewing machine (1) including a main shaft (10) rotationally driven by a sewing machine motor (13) ; a vertically moving sewing needle (6) and an overlooper (22) and an underlooper (34) respectively driven by the rotation of the main shaft (10) ; a single looper drive shaft (15) forming overlock stitches in cooperation with the overlooper(22), the underlooper (34) and the sewing needle (6) and rotationally driven by the rotation of the main shaft (10), shaft line thereof being arranged perpendicularly to the main shaft (10); and a swing generating member (18) having first and second swing generating portions (19) and (18a) fixed to the looper drive shaft (15) for swinging the overlooper (22) and underlooper (34) respectively; a first and second swing link mechanisms (25) and (35), both of which extending perpendicularly to the looper drive shaft (15), swinging the overlooper (22) and the underloopers(34) by conveying the drive force generated by the first and second sewing generating portions (19) and (18a).

摘要： A looper and knife driving mechanism of sawing machine, wherein an upper looper (30) and a lower looper (40) are provided under a needle plate (8), knife tips (31, 41) are disposed in the same direction so as to pass through the front side side-face of a needle (8) as viewed in the sawing direction, and the upper looper (30) and lower looper (40) are driven so that the routes thereof move on those surfaces substantially in parallel with each other in order to provide both the lock stitch and over-edge chain stitch functions and, in addition, form the sawing at once by a single sawing machine, the rotating motion of the upper shaft (S1) of the sawing machine is converted into a vertical motion through a motion converting mechanism (71) interlocked with the rotating motion so as to cut off a cloth edge (5c) by the vertical motion using an upper knife (72) and a lower knife (73) moving in association with the upper knife (72), the upper knife (72) being guided slidably by a female driving part (74) (710) pivotally supported by a machine frame FR and the motion converting mechanism (71) being connected to the upper knife (72) through a clutch (75)(750), whereby the clutch (75)(750) transmits a power to the upper knife (72) when the knife of the knife driving part (74)(710) is operated and drives the female driving part (74)(710) to an escape position when the knife is not operated so as to cut off a power to the upper knife (72).

摘要： In a looper and cutter drive mechanism for sewing machine, an upper looper and a lower looper are respectively disposed below a throat plate, respective loop-taker points of these loopers are arranged in the same direction such that the loop-taker points pass a front side of the needle as seen in the stitching direction. The upper looper and the lower looper are driven such that the upper looper and the lower looper perform movements having traces on planes substantially parallel to each other. Due to such a constitution, the looper drive mechanism has both of the lockstitching function and the over-edge stitching function and can perform both functions by a single sewing machine. Further, the rotational movement of an upper shaft of the sewing machine is transferred to the upward and downward movement by way of a motion transfer mechanism which is operated in an interlocking manner with the rotational movement and a fabric edge is cut by an upper cutter which is operated corresponding to the upward and downward movement and a lower cutter which is cooperatively operated with the upper cutter. Here, the upper cutter is slidably guided by a cutter drive portion which is pivotally mounted on a frame. The motion transfer mechanism is connected to the upper cutter by way of a clutch. The clutch transfers power to the upper cutter at the time of performing the cutters of the cutter drive portion and pivotally moves the cutter drive portion to a shunting position and interrupts the transmission of power to the upper cutter at the time of not performing the cutters.
