Machining portions such as a cutter portion, a slider inserting portion and an upper stopper attaching portion are provided around the vertical axis of a fixed table portion in order of machining. A fastener chain cut to have a predetermined length is held by the fixed table portion and a gripper of a rotator provided around the same vertical axis. The fastener chain is rotated and transferred to each of the machining portions based on the intermittent rotation and control of the rotator in the holding state in the gripper. Every time a predetermined machining is completed in each of the machining portions for the fastener chain rotated and transferred intermittently, it is possible to rotate and transfer the fastener chain simultaneously and intermittently to the next machining portion, thereby carrying out the necessary machining continuously.

Slide fastener manufacturing apparatus

A separable bottom end stop for a slide fastener comprising a box, a box pin, and an insert pin. Protruding guide portions which protrude onto respective fastener tapes are integrally molded with respective side faces at tape-sides of the box pin and the insert pin via thin guide portions. The separable bottom end stop is formed of polyacetal resin, and a distance d between each outer side face of the box and each of the protruding guide portions and a protrusion height h of each of the protruding guide portions from a surface of each of the thin guide portions when the box pin and the insert pin are mounted into the box satisfy the equation (I): tan (d/h) &gE;33&deg;, where d&ne;0. The separable bottom end stop becomes hard to be broken with having excellent durability, despite using polyacetal resin which allows various coloring achieved easily, but is easy to be broken.

In an automatic heat-fusible tape pieces attaching apparatus, a plurality of tape cassettes, each including a reel support part rotatably supporting a tape reel and a tape guide part defining a tape guide path extending from the reel support part in a direction of drawing a thermoplactic tape, the tape guide part having pressure rollers sectioning a part of the tape guide path, and a window through which part of the pressure rollers is exposed to the outside from the tape guide part, are detachably supported at predetermined distances on a tape cassette support base situated alongside of a traveling path of the strip and movable along the traveling path for positioning. The support base is moved to position and hold a desired cassette in an extension line of the attaching portion, and the tape is cut off as the tape piece is left on the attaching portion, whereupon the tape is attached to the front surface of the strip by a thermoplastic tape piece fusing means.

A method of continuous changing dye-color in spray dyeing for a long tape, which is fed by guides continuously. According to a preferred embodiment, one dye-solution is sprayed for the tape from at least one dyeing-nozzle connected to one feeding line, which is either of a pair of feeding lines and which feeds selectively the one dye-solution or one cleaning-solution. When the tape is fed with a predetermined length, the spraying of the one dye-solution is stopped. Then, the one dyeing-nozzle is exchanged with at least one other dyeing-nozzle by turning the one dyeing-nozzle away from the tape and turning the other dyeing-nozzle to the tape for spraying another dye-solution. While the other dye-solution is sprayed, the one dyeing-nozzle, which was used for spraying for a proceeding sprayed portion of the tape, and the one feeding line, to which the one dyeing-nozzle is connected, are cleaned with the one cleaning-solution to prepare for spraying a new dye-solution. Further, at just one time when an undyed portion, which is produced by the exchanging of the dyeing-nozzles, passes through each guide, the dye-solution attached to each guide is removed so as not to mix into a following sprayed portion of the tape.

A method which enables a dye to be weighted and taken out quickly at a high accuracy regardless of the required quantity of the dye by taking out the greater part of the required quantity of the dye in a powdery state and the remaining quantity of the dye in the state of a diluted solution, upon taking out the required quantity of the powdered dye, and an apparatus suitable for carrying out the above-mentioned method.

A dyeing apparatus for dyeing or otherwise treating an elongate fabric material includes a cylindrical vessel and a beam mounted concentrically therein and removable therefrom the beam having a plurality of chambers isolated one from another and a dye frame unit rotatably mounted on a driven shaft extending axially through the beam, a first motor rotating the driven shaft and a second motor operatively associated with a mechanism for moving the driven shaft axially toward and away from the first motor, and away from the driven shaft to adjust the overall diameter of the dye frame unit on which the fabric material is wound.

Apparatus for dyeing or otherwise treating an elongate fabric material

A box holder swingably mounted on a frame is angularly movable between a box receiving position and a box attaching position. The box holder has a casing, an anvil slidably disposed in the casing, and a pair of gripping jaws angularly movably disposed in the casing for gripping the box therebetween against an end of the anvil. A first fluid cylinder is disposed on the frame for pressing the anvil in the box attaching position. An ultrasonic horn mounted for movement toward and away from the box holder is pressed by a second fluid cylinder toward the anvil holder in the box attaching position to grip the box between the end of the anvil and the ultrasonic horn. While the box is gripped between the anvil and the ultrasonic horn, the ultrasonic horn is energized to apply ultrasonic vibrations to weld the box to the box pin inserted therein.

Apparatus for attaching boxes to slide fasteners with separable box and

Disclosed herein is an apparatus for producing a slide fastener having a separable end stop through the steps of attaching a pin, box pin, a slider and a box to a pair of stringers while the stringers are being fed in a parallel state by grippers, in which the stringers have a space portion devoid of fastener elements and upper stoppers affixed adjacent to the space portion. A slider attaching unit of this apparatus has a transfer holder for carrying the slider into the path of travel of the stringers from a slider supply device and a retaining device for retaining the slider between itself and the holder. The retaining device includes a stopper block and an engaging block which are driven so as to assume positions where both blocks cooperate with the transfer holder to retain the slider when the stringers are passed through the slider, after which the stopper block is driven so as to separate from the slider, whereby the slider is freed from between the transfer holder and engaging block automatically when the upper stoppers of the stringers engage the slider.
