Abstract: An automatic winding machine for automatically and certainly guiding and sticking not only one flexible tape-like article, but also a plurality of flexible tape-like articles on desired spool peripheral surface. While adhesive portions of one or more double-sided adhesive tapes fed in parallel are cut to every predetermined length, a separated paper is wound for a predetermined length. The severed adhesive portions of the predetermined length are stuck onto the back surfaces of the leading ends of the one or more tape-like articles. Individual leading ends of the tape-like articles on which the adhesive tapes are respectively stuck, are gripped by grippers and moved through the guide member to the winding spool. Thereafter, the leading ends of the tape-like articles are pressed and stuck onto the peripheral surface of the winding spool to wind automatically the tape-like articles for every predetermined length on the winding spools.

Abstract: A runner-strip and articles attached to the runner-strip are molded into a piece in an injection molding unit. The piece is pulled out of the injection molding unit by a pulling-out unit. A back end of the runner-strip is left in the injection molding unit and is continued to a subsequent runner-strip to form a series of the pieces. The articles are separated from the runner-strip by providing a shock to both sides of the articles. Collecting units are provided for collecting the articles and the runner-strip.

Abstract: A row of slide fastener coupling elements of synthetic resin or metal is pressed between a pair of first and second presser rolls having first and second confronting presser surfaces engaging legs of the coupling elements. The first and second presser surfaces have closest confronting portions spaced from each other by a distance equal to the width of each of the coupling elements. The second presser roll is displaceable with respect to the first presser roll to vary the distance. The first presser roll has a spur gear held in mesh with a pin gear on the second presser roll. The first and second presser rolls can be rotated in synchronism by the spur gear and the pin gear even when the second presser roll is displaced relatively to the first presser roll. The first and second presser rolls also have partition ridges for meshing engagement with the legs to keep them spaced apart at equal intervals. One of the first and second presser rolls has a third presser surface for engagement with coupling heads.

Abstract: A coupling-element pairing apparatus includes a substantially Y-shaped guide channel defined in a base and including a joint passage for interengaging disengaged rows of continuous filamentary zigzag coupling elements. The joint passage has a width narrow enough to substantially prevent interengaged rows of coupling elements from moving laterally with respect to one another. A pair of toothed guide wheels disposed one on each side of the joint passage for guidingly advancing the interengaged rows of coupling elements through the guide channel. Each guide wheel has a plurality of peripheral teeth, two adjacent ones of which project into the joint passage for holding therebetween one of the connecting portions of each row of coupling elements at opposite ends thereof without impairing the coupling elements.

Abstract: A clamping unit has a pair of clamping jaws movable toward each other by manually operable threaded rods to clamp a slotted hollow body such as a separable bottom stop member for a separable slide fastener on a beaded edge positioned between the clamping jaws. A central presser presses the slotted hollow body against shoulders of the clamping jaws to shape the slotted hollow body. The clamping jaws and the presser are adjustably limited in their coacting movement so as to handle slotted hollow bodies of various sizes. The clamping jaws and the presser are spring-loaded so that they will be automatically retracted out of an operating position upon release.

A lower jaw is secured to the other end of the first member and has at least two first recesses laterally spaced apart from one another by a predetermined distance equal to the element-to-element pitch of a concealed slide fastener to be repaired, each first recess being receptive of a prospective coupling element. An upper jaw is pivotally connected to the other end of the second member and has at its free end a second recess.

Abstract: A water-tight, air-tight or otherwise sealing slide fastener has a series of discrete coupling elements secured to a support tape, a connecting cord extending longitudinally through and interconnecting the series of individual elements in equally spaced relation and a series of sealing strips each clamping a region of the tape which is folded around the elements. The connecting cord is dimensioned to fill the interspaces between adjacent elements so as to prevent entry of foreign matter.

Abstract: A method and apparatus for attaching a reinforcing tape to an intermittent fastener chain. A fastener chain having alternate element-containing and element-free sections is advanced intermittently in the longitudinal direction thereof. When the fastener chain is stopped, a strip of reinforcing tape is moved transversely across an element-free section from the side edge thereof and is folded over the side edge, after which pressure is applied to the side edge from the top and bottom sides of the chain to adhere the strip of reinforcing tape to the side edge. The attachment of the tape is divided into a first attaching step of applying pressure solely to the vicinity of the side edge from both sides of the fastener chain, and a second attaching step of applying pressure to the entire portion of the element-free section having the strip of reinforcing tape folded thereon, from both sides of the fastener chain.

Abstract: Slide fastener coupling elements are continuously manufactured from a molded strip of coupling element blanks at a speed which is substantially the same as the speed at which the molded strip is produced on a die wheel. The strip of coupling element blanks, as it is withdrawn from the die wheel, is folded about its longitudinal axis into a U-shape while the strip is being heated, and then is heated by hot air before it is shaped into slide fastener coupling elements of a finalized shape as they are heat-set. Then, the coupling elements thus formed are cooled and discharged at a speed equal to the peripheral speed of the die wheel.

Abstract: An apparatus for manufacturing a fastener chain having solid sections by repeating the steps of providing a tape having perforated sections which include holes punched in a longitudinal edge of the tape, and solid sections, which are free of holes, alternating with the perforated sections, supplying the tape so that the perforated section thereof is placed between a stationary mold and movable mold, applying tension to the tape to stretch it, and then injection-molding fastener elements onto the tape at the holes. Stretching of the tape is accomplished by a sprocket wheel provided adjacent a freely rotatable drum. Teeth on the circumferential surface of the sprocket wheel are caused to recede below the circumferential surface of the freely rotatable drum when a solid section of the tape passes over the drum.

Abstract: A method of manufacturing a continuous slide fastener stringer, comprising the steps of: providing a continuous stringer tape having a plurality of openings along a longitudinal edge thereof at regular intervals of a first distance d; then placing a part of the tape between a pair of mold members defining a number of mold cavities spaced at regular intervals of a second distance D slightly greater than the first distance d; then stretching the part of the tape until the openings in that part are aligned with the mold cavities; then injecting melted synthetic resin material into mold cavities, while the mold members are closed, to form on the part of the tape of number of the injection-molded coupling elements one at each of the openings; and repeating the preceding steps, except the first-mentioned step, for a succeeding part of the tape.

Abstract: An apparatus for attaching a pair of U-shaped end stops each having a pair of opposed clinching legs to the respective longitudinal marginal edge portions of a pair of slide fastener stringer tapes comprises a guide block provided with a pair of elongate slots in which are slideably mounted a pair of punches. The U-shaped end stops are slideably positioned in respective ones of the slots and are orientated such that the two legs are in slideable engagement with the slot walls and the ends of the legs face toward the pair of stringer tapes. The slots are provided with shoulders configured to engage with one of the legs of the end stops to effect turning of the end stops about the shoulders in response to movement of the end stops by the punches to thereby position the two legs of the U-shaped end stops on opposite sides of the stringer tape. Further movement of the punches effects clinching of the legs of the end stops to the stringer tapes.

Abstract: An apparatus for producing a woven slide fastener stringer includes a loom for weaving a stringer tape and a rotor assembly for coiling an element-forming monofilament around a mandrel to form a coiled coupling element, which is then woven into the stringer tape along a longitudinal edge thereof. The rotor assembly comprises a rotor rotatably mounted eccentrically on a stationary shaft, and having a guide hole for passage therethrough of the monofilament and a pin angularly spaced 180 degrees from the guide hole and slidably received in a radial slot in a radial arm to which there is drivingly connected a drive gear rotatably mounted on the stationary shaft. When the drive gear rotates, the guide hole rotates at a reduced angular velocity as it approaches the loom, thereby allowing harnesses for warp threads which bind the coupling element to be moved across the orbital path for the monofilament without interference.
