Reißverschluß mit textilen Tragbändern, die zumindest längs des verschlußgliederseitigen Randes einen Randwulst aufweisen, mit angespritzten Verschlußgliedern aus thermoplastischem Kunststoff, die von einem die Tragbänder mit Bandschlitz umfassenden Reißverschlußschieber kuppelbar und entkuppelbar sind sowie mit einer Teilbarkeitseinrichtung aus thermoplastischem Kunststoff, die im Bereich von auf die Tragbänder aufgeschweißten Verstärkungsstreifen angespritzte Bauteile aufweist. Die Verstärkungsstreifen sind bis an die Randwülste geführt und mit Durchflußlöchern ausgerüstet. Die angespritzten Bauteile der Teilbarkeitseinrichtung sind oberseitig und unterseitig mit angeformten Zentrierflügeln versehen, die durch in die Durchflußlöcher eingetretenen thermoplastischen Kunststoff miteinander stoffschlüssig und mit den Tragbändern sowie den Verstärkungsstreifen formschlüssig verbunden sind. Die Zentrierflügel mit dem jeweils zugeordneten Tragband und den Verstärkungsstreifen weisen eine dem Bandschlitz des Reißverschlußschiebers angepaßte Dicke auf.
摘要:
A stabilizer link in which weight reduction can be achieved and the circumferential position and the distance between both housings can be adjusted, and a method for manufacturing same, are provided. A solid bar made of a light weight metal or a fiber reinforced plastic is used for a support bar 60. An end portion 61 of the support bar is inserted into a mold as a core, and a housing 50 is formed at the end portion 61 of the support bar 60 by injection molding. In this case, the resin is mold-shrunk, whereby a boss portion 52 of the housing 50 covers and adheres to the whole circumference of the end portion 61 of the support bar 60 thereof. Therefore, the boss portion 52 is rigidly fixed to the end portion 61.

Die Erfindung betrifft einen Schrumpfschlauch als Schutzvorrichtung für Kabel und Kabelbäume oder längliche Gegenstände. An den Längskanten (3, 4) der Schrumpffolie (2) eines aufgeschnittenen Schrumpfschlauches oder an den Seitenkanten einer streifenförmig zugeschnittenen umbiegbaren Schrumpffolie sind ineinandergreifende Hakenelemente (5, 6), bestehend aus dem gleichen oder einem anderen, mit dem Folienkunststoff verbindbaren Kunststoffmaterial (2) durch Anspritzen vorgesehen. Ferner sind ein Verfahren und ein Werkzeug zur Herstellung eines solchen Schrumpfschlauches angegeben.
摘要:
A description is given of a sealing slide fastener (10), comprising two tapes (1, 2) of elastic material with their edges (1b, 2b) facing each other, which are pressed against each other by the coupling of two sets of aligned teeth (3, 4) caused by the passage of a closing slider (8), in which at least the outer layers (1e, 2e) of the said two tapes (1, 2) and the said teeth (3, 4) are made from materials which can be welded together chemically.
摘要:
A color slide fastener and a method and apparatus for fabricating the same are disclosed, The method includes the steps of a tape arranging step for arranging a support tape of a slide fastener on a mold having a capacity having a plurality of unit fastening element molding material grooves for molding a plurality of unit fastening elements, a molding material heating and discharge step for separating a molding material of more than two colors from a source material supply unit by the colors by a molding material injection means and then heating and discharging the same, a moving step for grouping external molding material flow paths from the molding material supply unit to an injection port of the mold into more than two groups and then moving different colors molding material by the colors, an injection step for injecting the molding material into the unit fastening element molding material groove through a plurality of injection ports formed in the mold, and a cooling and extracting step for cooling and extracting the unit fastening element engaged with the support tape, for thereby easily injection-molding a unit fastening element (tooth of fastener) of a slide fastener in more than two colors for thereby diverging the design of various clothes and portable things and enlarging a design choice.
摘要:
Continuous injection molding apparatus for slide fastener chains. According to a preferred embodiment, this apparatus comprises single stationary mold (1) and two movable molds (2, 3). The stationary mold (1) is provided with a sprue (15) contacted with a nozzle (18) of an injection cylinder (9). These three molds are disposed so that the opposed parting planes (32-35) of the three molds are parallel each other. Then, the sprue (15) is communicated with each row of cavities (4), through each runner (14) or through each runner and each path. The fastener tapes (5) are transported intermittently in spaces formed between the molds respectively in a longitudinal direction. The molten material is shot from the injection cylinder to the sprue (15) and is injected into the rows of cavities (4) between two molds of these three molds through the runner (14) or through the runner and the path respectively. Then, the pairs of rows of fastener elements (6) are molded from the molten material in the rows of cavities (4) and attached simultaneously to the beaded edges. As a result, the plural number of slide fastener chains can be produced by one-shot injection with this apparatus having a normal area of longitudinal cross section.
摘要:
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.
