Definitions

  • the strip prior to the operation of the present machine, has previously been provided with gaps atspaced intervals where the head portions of a plurality of the engaged coilYconvolutions have been cut away leaving a length of chain between such gaps which ⁇ will correspond to the length of zipper that is desired.
  • This first operation leaves substantial scrap parts still attached to the tapes. These are called; the heel'v portions of the coils as distinguished from the head portions. ⁇ It will be understood that the strip is cut across the gaps making up individual zippers and if these heel portions are left in place, they will obviously be objectionablednk ⁇ the-.finished zipper. It is especially important that they be removedin fasteners which are to be equipped with separating bottom stops.
  • the machine removes these scrap portions of the coils by a single direct movementof ⁇ a ycarriage along the strip while the strip is held Iin a definitejpOSitiQnwith'a blade extending into ⁇ the gap which has been previously cut. j I Other objects and advantages of the invention will hereinaftermore fully appear.

  • the zipper strip as best seen in FIGS. 1 and ll, has a pair of tapes T ⁇ with fastener, elements C o-f the coil lfilament type attached thereto. ⁇
  • the coils are interengaged by their head portions, except for. ⁇ gaps 11 at spaced intervals.

  • This bed may be mounted for lengthwise adjustment upon arail 14 and the bed may be clamped to the rail in 'any adjusted position by hand-operated screws 15.
  • the rail ice 14 may be carriedv by suitable support brackets 16 at either end
  • the carriage, which includes the block 17, is mounted over the bed-for longitudinal sliding movement and for pivotal movementso that it can be lifted away from the bed to arrange the zipper strip.
  • the carriage block 17 is securely fastened to a guide rod 18 as by means of a stud 19 which is seen in dotted lines in-FIG. 2.
  • the guide rod can freely slide and rotate in a bearing block 20 which is rigidly secured to the bed by suitable bolts 21.
  • This bearing block 20 also acts as a stop to limit movement of the carriage toward the left. Movement of the carriage in the other direction is limited by a stop block 22 which is rigidly held to the bed -13 bya screw 23. This screw extends through an elongated slot 24 shown in dotted lines in FIG. 2, so that the stop can be adjusted lengthwise of the bed. A recess shown in dotted lines in FIG. 2 is for the purpose of accommodating the stud head 19. While the back portion of the carriage 17 is supported by the guide rod 18 in a cantilever fashion, the front portion rests uponA a narrow bearing surface 25 which is at a slightly higher level than the main portion of the bed 13 to provide a slot 26 for the tapes T of the zipper strip.
  • each of the mounting blocks 35 and 36 are the turrets 42' which are of like construction; one of them is shown in detail in FIGS. 8 and 9.
  • Each turret 42 is a cylindrical shell fitting in a cylindrical recess 43 in the top face of the turret mounting block 35, angularly adjustable about a vertical axis and is held in an)7 desired adjusted position by a set screw 44.
  • Each turret carries a tool holder in the form of a cylindrical post 45 which is adjusted vertically by a screw 46 having threaded engagement with the post 45, but not with the turret 42.
  • the end of the screw 46 abuts against the bottom ⁇ of the recess 47 in the turret to determine the vertical position of the post whereupon it can be locked in such position by the locking screw 43 which'has threaded engagement with the turret, but not with the post and it will abut the bottom of a recess 49 in the post so as to lock it in the desired adjusted position.
  • This particular detail is a known formv of tool adjustment and need not be further described.
  • the posts 45 carry the stripping lingers 50 and 51 which extend into drilled holes in the posts and may be adjusted inwardly and outwardly of the post and held by set screws, one of which is seen in FIG. 6 to 52.
  • These fingers are mounted at an acute angle to the center line of the zipper strip; in other words, they project forwardly anddownwardly into the line of the heel portions 14. In this position, when they are moved by the carriage, they will hook into the heel portions 12 and pull them away from the tapes as represented in FIG. ll.
  • a suitable handle 53 For the purpose of lifting the carriage when the latch 27 is released, and also for pulling the carriage along the bed, there is provided a suitable handle 53.
  • the undersurfaceV of the carriage block 1'7 has a groove 54 with sloping side surfaces for snugly receiving the interengagin g coils C of the zipper strip.
  • a groove S5 which, when the carriage is moved forward, can accommodate the positioning blade 56.
  • This blade has a comparatively thicker and longer base portion 57 with a curved bottom edge which is secured in a suitable recess of the bed 13 by means of a screw 58, as seen in FIGS. 3 and l0.
  • the upper portion 59 of the positioning blade 56 is made to a predetermined length equal to the length of the gap where the head portions of the coils have been cut away.
  • the blade 56 may be easily removed and replaced to accommodate gaps of different lengths.
  • the thickness of the upper portion 59 of the positioning blade 56 is at least as much as the normal spacing between the bottom legs 60 of the scrap portions i4, so as to position these scrap portions in a definite alignment.
  • the cutting blade will have left a somewhat wider gap between the upper portions of the scrap parts 14 and will have left the edges of the tapes T intact.
  • the zipper strip is placed over the positioning blade 56, there might be a tendency for the tape edges to crowd between the portions 60 of the scrap parts and the blade 56. This would interfere l with the accurate lateral positioning of the scrap parts preparatory to stripping.
  • the bed 13 is slightly undercut or grooved on opposite sides of the blade 56 as indicated by the numeral 61.
  • the zipper strip may come from any suitable continuous source, such as a roll, or it may come directly from the machine which has cut away the head portions of the coils. ln any case, some means should be provided to create tension on the strip as it moves to the machine.
  • the latch 27 is released from groove 33, the carriage swung upwardly while supported by the guide rod 18. This enables the operator to pass the projecting portion 59 of the positioning blade through a gap in the strip. Then the operator, making certain that the carriage block 17 is abutted against the stop 22, will swing the carriage down so that it bears on the surface and the latch Z7 will automatically snap into the groove 33. This will bring the pointed ends of the stripping fingers 5f) and 51 into stripping position where they will hook into the heel portions i4 which'constitute the scrap to be removed. Then the operator, grasping the handle 53, moves the carriage along the bed with the guide rod 18 sliding in the bearing 20, and the latch 27 sliding in the groove 33. This is a straight line action parallel to the direction of the strip so that the stripping fingers will pull the scrap portions 14 away from the stitches S where they may fall away or be removed by an air blast.
  • the stripping operation can be successfully performed only if the strippingfingers are accurateely positioned in various ways. It will be notedthat there is provided independent lengthwise adjustments by means of screws 40 between the mounting blocks 35- and 36 and the carriage block 1'7. Vertical adjustment of the tool holders in the mounting ⁇ blocks is provided by the screws 46 and 4S. Angular adjustment ofthe toolholders isper'- mitted by the cylindrical turret 42 and the cylindrical red cess 43 in each 'of the mounting blocks. Finally, endwise adjustment of each stripping finger 5t) relative to the tool holder, is accomplished by positioningit in the hole of the tool holder and anchoring the same by the screw 52.
  • said mounting means being movable relative to said bed and biade in a direction lengthwise of the zipper strip to remove the scrap parts along said gaps l" 2.
