Definitions

  • This invention relates to sliding-clasp fasteners and in particular to the positioning of the end stops thereon, particularly at the opening end of the fastener.
  • a pair of linked or otherwise integralised end stops is formed at the location of the said opening end of the fastener and is bent around for securing to the stringers and, after being mounted in position, is separated into two individual stops. During the operation of forming and separating the stops, the fastener is in the closed condition.
  • the present invention relates to sliding-clasp fasteners and particularly to a method of and apparatus for manufacturing and securing pairs of limit stops to limit the movement of the slider of such fasteners.
  • the movement of the slider of a sliding-clasp fastener must be limited both at the closed end as well as at the open end thereof.
  • the limit stop at the closed end of the fastener is r generally in the form of a common member joining both stringers, but at the open end, naturally each stringer requires its own stop.
  • the operation for dividing the pair of stops is initiated after the bending operation. and terminated during mounting.
  • Initiation of the division can be effected by forming a nick in the pair of stops by pressing a cutting edge into a recess of a bending matrix.
  • the parts adjacent the nick can be bent, during the nicking operation over the bending edges defining the recess.
  • the dividing and securing operation may be carried out after mounting the pair of limit stops in a subsequent operation with the same tool.
  • a matrix is introduced as a counter-support for one cutting edge, into the free slot between the support tapes of the fastener in the central area of the pair of stops.
  • the dividing and securing of the stops may alternatively be carried out after the mounting operation by a second tool, as is effected for the interconnecting elements.
  • the invention relates also to a machine for carrying out the method, comprising a cutting, bending and a pressure stamper as well as a bending and rolling matrix, and wherein a cutting blade is mounted on the pressure stamper for separating the pair of stops.
  • the bending matrix preferably has, in the area in which the cutting blade of 'the pressure stamper extends with respect thereto, a recess having two bending edges and the roller matrix has a recess for receiving said cutting blade. Furthermore, when transferring the cutting blade to the pressure area of the pressure stamper, curves can be made.
  • the advantages achieved with the invention consist more particularly in that the limit stops at the open end of a slidingclasp fastener can be mounted on the completely closed double stringers of the fastener, whereby the above-mentioned difficulties are minimised or removed. Since both the individual stringers of the fastener are in engagement when mounting the stops, it is ensured that the stops at both ends of the fastener will be at exactly the same level so that, on the one hand, the unsightly and disturbing appearance of the stop projecting beyond and to one side of the slider cannot occur when the fastener is closed and, on the other hand, a secure limitation of the slider travel is effected in that both the limit stops abut one another in the slider at. the same level.
  • a further advantage of the invention consists in that for manufacturing both limit stops at the open end of the slidingclasp fastener only one cutting and bending tool is required so that the machine can be essentially more simple and cheaper.
  • a particular advantage of the method according to the invention is to be seen furthermore in that for manufacturing the pair of stops, material of the same type and size can be used as for manufacturing the connecting part at the closed end of the fastener and these can be claw or hooked connecting parts of known design.
  • FIG. I shows a cross-section of a device for manufacturing and securing limit stops in the working position, in which the stops are not yet punched and bent,
  • FIG. 2 shows a plan view of the lower part of the device according to FIG. 1,

  • the contours of a pair of limit stops 2 not yet bent having the claws or hooks 3 are clearly to be seen therein.
  • FIGS. 1 to 6 describe the sequence of operations for making and securing pairs of limit stops against movement of the slider, in detail.
  • the cutting and bending stampers 20 and the bending stamper 21 are moved together upwardly in the direction of the arrow shown in FIG. 3.
  • This action punches out a pair of limit stops 2 from the flat wire and its claws or hooks 3 are bent upwardly by 90 by means of the inserted bending matrix 5.
  • the position of the device after this punching and bending operation is shown in FIG. 3.
  • the cutting and pressure stamper 7 is pressed in the direction of the arrow in FIG. 4 upwardly against the bending matrix 5.
  • the nick 4 shown in FIG. 4 is made in the centre of the pair of stops 2.
  • the pair of stops 2 is simultaneously bent during the nicking operation over the bending edges 9 of the recess 8.
  • the nicking process is shown in FIG. 4 in its central stage.
  • the bending matrix is withdrawn to the side against the direction of the arrow in FIG. 2 out of the path of movement of the cutting and bending stamper 20, the bending stamper 21, and the cutting and pressure stamper 7.
  • Both the cutting and pressure stamper 7 as well as the cutting and bending stamper 20 and the bending stamper 21 can now be moved together upwardly towards the roller matrix 13.
  • the cutting and bending stamper 20 and the bending stamper 21 have become stationary by striking the roller matrix 13 and by pressing the carrier tape 12 of the fastener against the bending matrix 13, the carrier tapes are fixed in position, and the cutting and pressure stamper 7 moves further upwardly.
  • the claws or hooks 3 of the stops 2 are pressed by their apices by means of the carrier tape and begin their rolling movement which is guided by means of the depressions 23 in the rolling matrix 13.
  • the nicked pair of stops is completely separated so that two individual limit stops 11 are produced.
  • the position of the device after separating the pair of stops 2 into two individual stops 11 is shown in FIG. 5.
  • the claws 3 are completely rolled about the tape bulges 10.
