Patent number: 6634066Abstract: In a upper stopper device for a slide fastener having a cross section of a substantially U shape, which is adapted to be attached continuously to a fastener element row of a stringer capable of being engaged with or separated from each other, an end portion of the upper stopper device opposite to the fastener element row is formed with a widened portion, which abuts against wing plates at a shoulder opening of a slider into which the stringer is inserted so that the slider can stop. Further, a caulking portion is formed in a range between the widened portion and at an end portion side toward the fastener element row. The slider abuts against the widened portion of the upper stopper device attached to the stringer so that it reliably stops.Type: GrantFiled: February 26, 2002Date of Patent: October 21, 2003Assignee: YKK CorporationInventors: Yozo Okada, Futoshi Kozato, Yusuke Meiwa

Patent number: 5197686Abstract: A rack for storing a plurality of spools with elongated strips wound therearound comprises a box-like frame including a pair of parallel spaced plates; a plurality of partitions, each of which has on one of its surfaces a support axle for rotatably and releasably holding the spool; and means for releasably fastening the partitions in a parallel spaced relation to each other between the plates.The rack further includes elongated lock plates which have slots and notches formed in and arranged at uniform intervals longitudinally of the elongated lock plates. The lock plates are attached to the rack by pins protruding through the slots for slidably holding the lock plate to a front surface of the rack.Type: GrantFiled: July 30, 1990Date of Patent: March 30, 1993Assignee: Yoshida Kogyo K.K.Inventors: Yozo Okada, Akiyoshi Kando, Kazuki Kuse

Patent number: 5138763Abstract: A method of and apparatus for manufacturing slide fasteners of selected product lengths from an elongate continuous stringer chain, the method comprising selecting predetermined fastener component parts from among a plurality of such respective component parts which differ in type, form, material and color, feeding and applying the selected parts one at a time to the stringer chain. The apparatus reducing the method to practice comprises operating units arranged to selectively feed and apply the component parts under computer program control.Type: GrantFiled: August 13, 1991Date of Patent: August 18, 1992Assignee: Yoshida Kogyo K.K.Inventors: Hiroshi Mizuno, Kazuki Kuse, Shunji Akashi, Hiroshi Yoshida, Yozo Okada, Tatsuo Ito

Patent number: 4770566Abstract: A slide fastener overturning conveyer includes an elongate hollow rectangular guide member having a guide channel for the passage of a slide fastener, and air nozzles disposed adjacent to an inlet of the guide channel and directed toward an outlet of the guide channel. The guide member is rotatably movable about its longitudinal central axis through an angle of 180 degrees for overturning the slide fastener while the latter is received in the guide member. The air nozzles eject a compressed air to convey the overturned slide fastener. The angular movement of the guide member and the compressed-air ejection are controlled by a sensor provided for detecting leading and trailing ends of the slide fastener. The overturning conveyer thus constructed is relatively small and simple in construction and is effectively operative even when a slide fastener is relatively long.Type: GrantFiled: April 15, 1987Date of Patent: September 13, 1988Assignee: Yoshida Kogyo K. K.Inventors: Yozo Okada, Akiyoshi Kando

Patent number: 4624369Abstract: Slide fasteners are fed longitudinally one at a time along a path by at least one stream of air flowing along the path, and are then introduced into a clearance or gate which is narrow enough to prevent the passage of sliders so that when the slide fasteners have respective sliders, they are stopped at the gate, while when the slide fasteners have no sliders, they are allowed to pass through the gate and be further advanced by the stream of air. Thus the slide fasteners are automatically sorted or separated into two groups according to the presence of the sliders. Thereafter, the stream of air is interrupted whereupon the slide fasteners stopped at the gate are allowed to fall from the path into a container disposed below the gate. The slide fasteners thus fallen are disposed in the container in juxtaposition.Type: GrantFiled: August 14, 1984Date of Patent: November 25, 1986Assignee: Yoshida Kogyo K. K.Inventor: Yozo Okada

Patent number: 4570422Abstract: A number of elongate articles such as slide fasteners are discharged from a discharging mechanism and placed on a length of a band web which has been supplied from a reel on a bundle tray by means of a feed mechanism. The length of the band web has a free end and an opposite end gripped by a gripper mechanism. End portions of the length of the band web are ultrasonically fused to each other by a fusing mechanism constituted by an ultrasonic horn and an anvil. The opposite end of the length as it is gripped by the gripper mechanism is cut off by a cutter mechanism to form a band bundling the elongate articles, which are then discharged by the bundle tray.Type: GrantFiled: August 10, 1984Date of Patent: February 18, 1986Assignee: Yoshida Kogyo K.K.Inventors: Kozo Watanabe, Masashi Kawada, Yozo Okada
