Definitions

  • a separable slide fastener includes two rows of fastener elements having at one of their ends a separable coupling device consisting of respective male and female members, said female member being in the form of a housing to receive the male member.
  • a process for the manufacture of such a slide fastener there are provided the steps of manufacturing the housing separately by moulding it from a thermoplastic material, engaging the housing onto an end of a supporting tape for a row of fastener elements, and securing said housing in position on said tape end by driving through a wall of said housing a means serving to force the material of said wall towards the inside of said housing.
  • the present invention relates to slide fasteners of the so-called separable type, i.e. fasteners of which the two rows of fastener elements can be rendered completely independent of each other, contrary to those of the customary type, in which the two rows of fastener elements are permanently attached to each other at their respective ends.
  • fasteners of this type offer the advantage of enabling the two parts of an article to which they are fitted to be completely separated from each other.
  • These coupling devices generally consist of a housing on the corresponding end of one of the rows of elements and a protuberance serving as a hooking device and added to the end-of the other row and serving to engage the housing provided on the first row.
  • certain separable fasteners comprise metal coupling devices added to the ends of their two supporting tapes and secured in position by setting or mounting them.
  • This method involves a number of drawbacks, particularly the risk that the coupling devices will be torn ofie in the course of use.
  • the two coupling devices are provided by moulding them, in a plastic material, directly onto the corresponding ends of the two tapes of the fastener. This method of manufacture enables the coupling devices to be faultlessly secured in position.
  • the construction of the female piece nevertheless entails a certain number of diiculties, owing to the fact that it has to assume the shape of a hollow housing.
  • the object of the presentv invention is therefore to provide a new process for the production of coupling devices Mice for a separable fastener, this process being so designed as to eliminate the various drawbacks of those at present adopted.
  • the present process is characterized by the fact that the housing is manufactured separately, by moulding it from a thermoplastic material, and after it has been afixed to the corresponding end of the supporting tape of the respective row of elements it is fixed in position by driving through one of the walls of this housing one or more devices brought to a suitable temperature or subjected to ultrasonic vibrations, so that they drive the material of this wall towards the inside, thus setting or welding this housing in position.
  • the housing is intimately sealed to this latter. Tihs welding effect is obtained by the partial melting of the material of the housing as a result of the temperature rise which it undergoes in the place where the driving means engaged in it are driven inwards. This renders the said coupling device fully integral with the reinforcement member.
  • the invention also relates to slide fasteners of the separable type which are constructed by means of the present process.
  • FIG. l is a plan view, from above, of the ends of the two rows of fastener elements of a slide fastener, after the construction of a reinforcement plate provided on each row;
  • FIG. 2 is a plan View, from above, of one of the said two ends, after the female housing has been placed thereon and secured thereto;
  • FIG. 3 is a plan view, from above, of the corresponding ends of a separable fastener constructed by the present process
  • FIG. 4 s a view, in perspective, of the female housing provided in accordance with the present process
  • FIG. 5 is a cross sectional view of the said housing, along the line V-V of FIG. 4;
  • FIG. 6 is a sectional diagram, similar to the foregoing, and illustrating the operation of placing the said housing in position
  • FIG. 7 is a partial section, in accordance with a similar plane but on a different scale, and illustrating the method by which the housing is rendered integral with the corresponding reinforcement plate;
  • FIG. 8 is a plan view, from above, of an alternative version of the said housing, after it has been secured in position;
  • FIG. 9 is a sectional view along the line IX-lX of As indicated above, FIG. 1 is a partial plan view, from above, of the two rows of fastener elements of a slide fastener of the separable type, before the completion of its manufacture by the application of the present process.
  • reference numbers 1a and 1b refers to the two rows of fastener elements of the corresponding fastener, while reference numbers 2a and 2b indicate the tapes by which they are supported. This diagram nevertheless only represents the end of these two rows of elements, where it is intended to provide the separable coupling devices.
  • the operation preferably commences by the addition, to the corresponding end of the two parts of the fastener, of two reinforcement plates 3a and 3b, of a thermoplastic material.
  • These can be provided by directly moulding them onto the tapes 2a and 2b, after the corresponding ends of the two rows of fastener elements have been cut off in that position.
  • these reinforcement pieces can also be provided by the welding of a fragment of thermoplastic material under the effect of ultrasonics.
  • These reinforcement pieces can be provided by any other suitable process.
  • a protuberance of which the purpose is to provide the male coupling device of the fastener, is then provided, in a known manner, on one of the said plates, in the present instance on the plate 3a.
  • This protuberance may with advantage consist of a longitudinal tenon 4a, substantially forming a prolongation of the corresponding row of elements. Needless to say, this tenon is then moulded in one piece with the adjacent plate 3a.
  • a projecting protuberance is also provided on the second reinforcement plate 3b. Furthermore, this protuberance may likewise take the form of a longitudinal tenon 4b, substantially forming an extension of the corresponding row of elements.
  • this tenon does not entail any diiiiculty of a technical nature.
  • the fact is that, just like the tenon 4a serving as a male coupling device, it can be provided with a mould of a very simple shape moving perpendicularly to the plane of the corresponding tape.
  • female coupling devices intended to -be added to the reinforcement plates 3b provided on one of the two parts of the slide fastener in course of manufacture, are produced independently.
  • Each of these two devices consists of a housing 5, moulded from thermoplastic.
  • the inside of this housing is provided with two parallel channels 6a and 6b which lead onto two opposite walls of the housing via two slits 7a and 7b.
  • these two channels also lead to one of the ends of the housing, of which the other end is closed.
  • the shape and dimensions of the two channels 6a and 6b are such that the first can serve to accommodate the tenon 4 constituting the male coupling device of this fastener, while the second, 6b, can accommodate the tenon 4b provided on the reinforcement plate 3b.
  • the said housing is placed on the reinforcement plate 3b of one of the two parts of the fastener, in the course of manufacture, by causing the housing to engage the plate by inserting the projecting tenon 4b of the latter into the channel 6b.
  • This is an easy operation to perform, as it suffices to place the open end of the housing opposite the reinforcement plate 3b in such a way that the tenon 4b of the latter can enter the channel 6b,
  • driving devices may consist, with advantage, of two metal rods 9, to which ultrasonic vibrations are imparted, and which for this purpose are integral with a generator for such vibrations.
  • these rods are then driven through the upper wall 8 of the housing 5, in that part of the said wall which is situated above the channel 6a containing the tenon 4b borne by the reinforcement plate 3b.
  • this ring-shaped projection is somewhat similar to the phenomenon which may be observed in certain cases when a hole is punched into a comparatively thick metal plate.
  • this annular projection forms on the surface situated opposite to the tenon 4b borne by the reinforcement plate 3b. Under these circumstances, the said annular projection sets or mounts the housing 5 on the said reinforcement plate. This enables the housing to be firmly held in place.
  • annular junction zones 11 are formed between these two elements, as may be seen, moreover, from FIG. 7.
  • the housing 5 is thus rendered fully integral with the reinforcement plate 3b, so that there is no danger that it will become detached during use.
  • this same operation can be performed by driving in metal rods brought to a suitable temperature.
  • the corresponding operation can be carried out with an extremely simple device, comprising, on the one hand, a die of which the purpose is to accommodate, temporarily, the reinforcement plate 3b with housing 5, and on the other hand, two movable metal rods 9, capable of being moved downwards in order to be driven through the upper wall of the housing.
  • 'I'hese rods are borne by an ultrasonic generator or by a support comprising suitable heating devices, such as electrical heating elements, as the case may be.
  • the insertion points 10 for these rods may occupy various positions. In the example shown in FIGS. 1-7, these insertion points are situated above the longitudinal tenon 4b of the reinforcement plate 3b. They may nevertheless be positioned beyond this longitudinal tenon, but in the immediate vicinity thereof, as is the case in the variant shown in FIGS. 8 and 9.
  • the two holes 10a made in the upper wall of the corresponding housing 5a, are situated opposite the reinforcement plate 3b, but in the immediate vicinity of the longitudinal tenon 4b. This enables the housing to be secured in position in a fully satisfactory manner.
  • a different number of insertion points can be provided inside the upper wall of the housing. Possibly one single such point might suflice to enable the latter to be secured in position.
  • the devices used for the production of these insertion points may have cross-sections of any desired shape. Furthermore, it is obvious that these insertion points could be made through the lower wall of the housing 5 or 5a, instead of in its upper wall.
  • the end of the tape 2b need by no means be provided in advance with a reinforcement plate 3b. If this tape contains fibres of a thermoplastic material, the housing will then be directly welded to it at the points where the rods 9 are driven into it. At all events, however, this housing is secured in position by the setting or mounting effect obtained by driving material forming part of its wall, by means of the rods 9 driven through it.
  • the housing 5 or 5a When the housing 5 or 5a has been secured in position, it may serve as a female coupling device for the corresponding ends of the two rows of fastener elements of the fastener.
  • the channel 6a provided in this box can then accommodate the longitudinal tenon 4b which is provided on the reinforcement plate 3b and which constitutes the corresponding male coupling device.
  • the present process makes it possible to manufacture, under extremely advantageous conditions, slide fasteners of the separable type, from lengths cut olf a continuous run of mutually complementary parts, each consisting of a row of fastener elements aixed to a supporting tape.
  • the invention also covers other slide fasteners which can be produced by this process.
  • the fastener elements of these fasteners may be of any type.
