摘要： PURPOSE:To provide a warp guiding device in a multi-spindle weaving machine, making same the contact angles between warp and a compensator cam respectively at its major axis and minor axis. CONSTITUTION:A compensator cam 32 is arranged at a height position of just 1/2 difference H between a height position of a ring-shape 23 and a height position CL1 of a horizontal movement locus of a yarn guide 31a. the compensator cam 32 guides each warp (a) pulled out from each beam 21 and conducted to a three-spindle weaving mechanism 25 not to change its length. The ring- shaped guide 23 is set in such a way that its radius R is half the sum of a radius of major axis (1/2 length in the weaving width direction) of a warp movement locus which is drawn by the yarn guide 31a through a circulating moving chain and a radius of minor axis (1/2 length in the direction intersecting perpendicularly to the weaving width).

摘要： PURPOSE:To provide a method and apparatus for the treatment of weft-insertion miss in multi-spindle loom capable of automatically inserting a weft in the case of weft-insertion miss even at an increased weaving speed. CONSTITUTION:In a loom capable of correcting weft-insertion miss, the working position of a frame stopped by weft-insertion miss is detected by an encoder 48 (working position detection means). When the stop position is within a range to enable reverse rotation to return to the normal stop range enabling the single operation of a weft-insertion mechanism 7, the whole frame is automatically rotated in reverse direction to the normal stop range and, thereafter, the weft-insertion mechanism 7 is separated from the other mechanisms 11 and singly operated to perform the weft-insertion at the position before the insertion miss.

摘要： PURPOSE:To improve the efficiency in manufacturing by aligning numerous rings fore and aft and right and left, intermittently moving to the front part as well and linking the mutual adjoining the right and left, before and behind of the ring respectively by a wire simultaneously. CONSTITUTION:A nearly triangular vibration table 12 is arranged to a ring feeding device 6 and a ball feeder 18 is set up on a frame 11. The ring 2 inputted into a ball 19 is aligned with ascending a feeding path 20 by vibration and fed onto a ring moving path 16. A transfer device 17 performs an intermittent transfer by aligning the ring 2 by one pitch and two pitch transfer devices 25, 26. At the ring 2 stopping time a horizontal linking device 8 bends the horizontal direction of the ring 2 by linking by a short wire 3 all at once at pitch P2 and a fore and aft linking device 9, 10 performs the simultaneous linking of a wire 3 at pitch P1 in the front and back direction. The manufacture of a product is thus automatized and the production efficiency is improved.

摘要： PROBLEM TO BE SOLVED: To improve a processing speed relating to an exposure device which subjects a circuit board to be exposed which is a body to be exposed to exposure processing in the state of putting the circuit board in a perpendicular posture state. SOLUTION: This exposure device has a receiving side attraction arm for changing the posture of the printed circuit boards 11 to be supplied in a horizontal posture so as to put the circuit boards to the perpendicular posture and a transporting mechanism 20A which successively transports the printed circuit boards 11 form a posture change position (P1) where the printed circuit boards 11 is subjected to the posture change to exposure positions (P2 and P4) where the printed circuit boards are subjected to the exposure processing, and an ejection position (P5) where the printed circuit boards 11 subjected to the exposure processing is ejected. Exposure lamps 31A and 31B are so arranged that the optical axes (LL1 and LL2) of the exposure lamps 31A and 31B intersect orthogonally with the transporting direction (a direction X1) of the printed circuit boards 11 and the exposure device is so constituted that the printed circuit boards 11 are transported while the exposure processed surfaces of the printed circuit boards 11 maintains the state perpendicular to the optical axes (LL1 and LL2) in the transporting process of the printed circuit boards 11.

摘要： PROBLEM TO BE SOLVED: To completely suck and remove chips generated in a tool insertion hole of a presser member on the lower side of a pressure foot. SOLUTION: When a presser member 24 is pressed against the top surface W1 of a work with a printed circuit board laminated and an air flow by a suction acts the inner space of a pressure foot 20, the outside air flows into a tool insertion hole 30 from air in-flow channels 50, 51. The outlets of the air in-flow channels 50, 51 are disposed in the circumferential direction without clearance, therefore an inflowing air flow evenly-acts the whole periphery of the inner-periphery surface lower edge part of the tool insertion hole 30 evenly, so that no airdrift of the in-flow air is generated. It is thus possible to prevent chips generated by a tool from remaining at the inner surface of the tool insertion hole 30.

摘要： PURPOSE:To smooth the movement of warp yarn moving in pressure contact with the outer periphery of a compensator cam of a loom for triaxial woven fabrics, etc., in the weaving width direction during the weaving. CONSTITUTION:A compensator cam 32 between a triaxial weaving mechanism 25 for interweaving many warp yarns (a) while moving the warp yarns relatively to weft yarns and a warp yarn feeding part 2 horizontally rotating synchronously with the movement of the warp yarns in the triaxial weaving mechanism 25 is equipped with a vibrator 40 and the warp yarns (a) are slid and guided with the compensator cam 32. The compensator cam 32 is attached through a vibration-proof member 29 to a support 28 hung from a traverse frame 27 so as not transmit the vibration of the compensator cam 32 to the support 28. Vibration is applied to the compensator cam 32 itself with the vibrator 40 installed in the compensator cam 32. Thereby, the warp yarns (a) are smoothly moved in the weaving width direction.
