Abstract: It is an object of the invention is to provide a method and a apparatus for adjusting suction of a cutting machine capable of cutting even an elastic sheet material in an appropriate compression state by suppressing fluctuation in the degree of compression of the sheet material. A set value of a suction pressure is set such that an absolute value of the suction pressure, which is a negative pressure lower than the atmospheric pressure, becomes larger as a numerical value thereof becomes larger. For one-piece cutting as shown in FIG. 1B, the set value of the suction pressure is increased since the cutting distance of an already-cut portion is increased as cutting progresses. For stacked cutting as shown in FIG.

Abstract: A carriage which completes one course of knitting to the knitting end of a fabric is stopped. Knitting in a next course is performed when the carriage reverses its moving direction and re-starts its movement. Since the knitting yarn is not knitted to the fabric until a carrier brought by the carriage reaches a position of a knitting needle holding the stitch of the fabric at the knitting end, the knitting yarn existing in a feeding path between a yarn feeding mechanism and the carrier is excessively increased and a slack is generated. Since a distance between a yarn feeding port formed at a carrier's frontal end and the knitting needle at the fabric-knitting end is also reduced, the knitting yarn is further increased excessively. The further-excessively-increased knitting yarn is taken in by a yarn feeding means by reversing a servomotor, and further pulled in by a rewinding arm.

Abstract: Two blades (14, 14) of a slider of a compound needle move back into blade grooves (8, 8) of a needle body (4) on the left and right side of a partition wall (9). An opening (18) is provided at the front ends of the blades (14, 14), and curved portions (19, 19) are provided on the backside of the front ends of the blades. Further, a thick section is provided at the front end of the partition wall (9), and a thin section is provided on the backside of the thick section. When the blades move forward from the blade grooves, the blades are centered at the thick section so that even if a lateral force is applied from a knitted loop to the blades, deformation of the blades is prevented by the contact of the two blades at the curved portions. In the blade grooves, the curved portions contact the thin section of the partition wall such that the force applied between the blades and the blade grooves does not increase.

Abstract: A weft knitting machine having a movable sinker capable of securing a large space at a needle bed near a knitting fabric knitting area and making a pause in the state of stopping action on the knitting fabric knitting area. A sinker operating cam mechanism (10) installed in a carriage acts on the butt (12c) of a sinker jack (12) to move the sinker jack (12) backward from a mouth part (2) so that the acting part (8c) of the movable sinker (8) can retract from the mouth part (2). The sinker jack (12) is locked to a moved back position by a locking mechanism (16). Since a wire (17) passed through a needle plate (5) is utilized to lock the sinker jack (12) in the locking mechanism (16), the locking mechanism (16) can be reduced in size. To lock the sinker jack (12) to the wire (17), the sinker jack (12) comprises a projection (12f).
