FIELD OF THE INVENTION a second coupling belt, the apparatus comprising: a feed path along which the chain can be fed; a device in the feed path for folding one slit edge twice at a time; 15 a device in the feed path for attaching a bottom response to rows of clutch members and cutting the chain across a free space of the clutch members to provide a zipper with a split rim; and an ejector roller device for removing the finished zippered zipper 20.

State of the art

Various machines have been proposed for the sequential automatic production of zippers. However, in the past, no machine has been proposed or used to make zippers automatically attached to them with slit edges.

It has been common practice to use zippers with pre-sewn splits to provide greater efficiency when zippers need to be fastened to close the front of men's pants. The slit is sewn longitudinally into the second clutch strip substantially along the central line, the slit being wider than the zipper: When sewing the zipper, the slit is folded twice around the stitch and then sewn into the trousers. In the manufacture of zippers with a split edge, if the split edge were to be attached to a finished zipper, there would be difficulty in sewing the split edge zipper 2 77144 with a sewing machine due to the presence of a slide in the zipper. Therefore, it is more advantageous to sew the slit edges to the continuous zipper in advance and then manufacture the continuous zipper into individual finished zippers. However, since the split edges are already sewn into a continuous zipper, the split edge must be folded before the slider is mounted on the chain, and the folded split edge has an increased thickness on the other side of the chain, which has prevented accurate chain feed forward. A folded slit edge attached to the second clutch strip 10 makes the strips different in stiffness and less secure in threading their edges through the slider. In order to feed the chain accurately, it is possible to convey the chain with a feed roller device which only touches the row of clutch members. However, the slider becomes a resistance to the feed roller device. For the reasons set out above, until recently, only hand-held devices for making zipped zippers have been available.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a machine for making zippers with split edges automatically from a continuous zipper in which such split edges are sewn in advance.

The apparatus according to the invention is characterized in that the apparatus further comprises a device on the feed path for mounting one slider at a time in rows of coupling members; and 30 feed roller devices for feeding the chain along the feed path in optional contact with the rows of coupling members interconnected; wherein the feed roller device is available in synchronism with the discharge roller device. Many other advantages and features of the present invention will become apparent from the following detailed description and the accompanying drawings, which illustrate by way of example a preferred embodiment of the present invention.

15 Detailed description

As shown in Figures 1 and 2, the continuous zipper 10 consists of two continuous clutch strips 11, 11 supporting rows of interconnected discrete clutch members 12 at opposite longitudinal edges 20, the interconnected rows of clutch members 12 having a member-free space or gap 13. Chain 10 the wider slit edge 14 is sewn to the second clutch strip 11 in two rows of sewing threads 15 along the substantially central portion of the slit edge 14. The chain 10 with its sewn-on split edges 14 is progressively processed as follows:

When the chain 10 travels in the direction of arrow 16, halkioreunus 14 is folded in Figure 2, the double-folded around the sewing thread 15, thereby exposing rows in engagement with each other the coupling elements 12. The slider 17 is placed in the free space 13 from the coupling member 30 when the rows of coupling members 12 interconnected are threaded through the slider 17 from its open edges 18, 18. The slider 17 has a pull tab 19 with through holes 20. The bottom stops 21 are then fastened to each other in the coupling members 12. 35 to the ends of the rows and the chain 10 is cut to a predetermined length, whereby the zipper 22 with its split edges 14 is completed.

The continuous zipper 10 with split edges 14 can be handled

II

5,7144 bogies for a zipper 22 with a split rim 14 on a machine, generally indicated at 25 in Figures 3 and 4. The machine 25 comprises essentially a split rim folder 26, a 1-piece fastener 27, a bottom-5 stop fastener and a chain cutter 28, parts of which are fitted in said sequentially on the feed path 29 of the continuous zipper 10 and mounted on the base of the machine, i.e. the frame 30.

The feed path 29 is substantially defined by a guide roller device 31 in the splitter 26 folder 26, a feed roller device 32 located downstream of the slider fastener 27, and an exit roller device 33 located downstream of the bottom stop positioner and chain cutter 28.

As shown in Fig. 5, the guide roller device 31 consists of an upper and a lower guide roller or idler roller 34, 35 for guiding rows of interconnected coupling members 12 therebetween. The upper roller 34 is rotatably mounted on a shaft 36 attached to a vertical support plate 37 mounted on the machine base 30. The lower roller 35 is mounted on a shaft 38 passing through the vertical support plate 37 and supports a brake mechanism 39. This brake mechanism 39 includes a circular disc 40, wedged rotatably, a brake drum 41 with a brake shoe 42 fitted with a compression fit on the brake drum 25 and fixedly mounted on a mounting plate 43 mounted on a vertical support plate 37, and a clutch plate 44 movably axially connected to the brake drum 41 by pins 45. An electromagnet 46 is mounted on the vertical support plate 37 near the disc 40. In response to the magnetization of the electromagnet 46, a switch lamella 44 may be pressed against the disc 40 to stop the rotation of the guide roller device 31, thereby interrupting the passage of the chain 10.

When the chain 10 is fed through the guide roller device 31, the slit edge 14 begins to progressively fold under the action of the inclined guide plate 35 before it reaches the guide roller device 31, and folds completely twice after passing through the guide roller device 31, as shown in Fig. 6.

6 77144

As shown in Figures 3, 4 and 6, the feed roller device 32 comprises an upper and a lower roller 48, 49 for feeding rows of coupling members 12 interconnected therebetween. The upper roller 48 is rotatably mounted on a support 5 (Fig. 4) movable vertically by the first medium cylinder 23 to bring the upper roller 48 toward and away from the lower roller 49. The lower roller 49 is rotatably mounted via a shaft 51 to a bearing 52 mounted on a bracket 53. The shaft 51 10 supports a sprocket 54 at its end which is driven by an endless chain 55 via a sprocket 56 mounted on the shaft 57 of an off-roller device 33. As shown in Fig. 6, the upper and lower rollers 48, 49 are serrated or roughened with a circumferential surface 58, respectively. 59, with rows of coupling members 12 15 interconnected for gripping and transporting.

As shown in Fig. 7, a freewheel clutch 60 is disposed between the shaft 51 and the roller 49 to rotate this roller in only one direction, to supply rows of coupling members 12 20 in interconnection.

As shown in Figures 3 and 4, the discharge roller device 33 consists of two laterally spaced upper rollers 61, 61 and a lower roller 62 cooperating with the upper rollers 61, 61 to remove the finished traction chain between them. Both upper rollers 61, 61 are rotatably mounted at one end of a lever 63 which is pivotally connected by a pivot pin 64a to a support 64 mounted on a vertical mounting plate 65. The other end of the lever 63 is pivotally connected to a piston rod 66 of a second fluid cylinder 66 supported by a vertical mounting plate 30 65.

Thus, the levers 63, 63 are pivotally movable to bring the upper rollers 61, 61 into contact with and apart from the lower roller 62 in response to the operation of the second media cylinder 66. The upper rollers 61, 61 are usually forced against the lower roller 62 by means of two tension springs 63a, 63a acting between the respective levers 63, 63 and the vertical mounting plate 65. The levers 63, 63 are loosely connected to the piston rod of the cylinder 66 so that

II

The levers 63, 63 are pivotally movable against the tension of the respective springs 63a, 63a as the chain 10 is conveyed between the upper and lower rollers 61, 62. As shown in Figure 7, the lower roller 62 is supported by a shaft 57 supported on a vertical mounting plate 65 and driven to rotate by a motor 67 of a drive mechanism 68 mounted on a machine base 30. The drive mechanism 68 includes a pulley 69 rotatably mounted at that end of the shaft 57 , which is farther from the sprocket 56 and rotatable by a belt 70 running around a pulley 69 and a pulley (not shown) coupled to the motor 67. The clutch lamella 71 is axially displaceable by a pin 72 on the pulley 69. The clutch plate 73, which supports the electromagnet 74, is wedged on the shaft 57 in an axially opposite position to the clutch lamella 71. The lower roller 62 is axially disposed between the two setting rings 75, 76 and resiliently pressed between them by two springs 24 (only one is shown) acting axially on the setting ring 75. The gear 77 is mounted on the shaft 57 via a rotary clutch 78 and held in gear by the rack. 80, which is vertically movable by a third medium cylinder 81 (Figures 3 and 4).

As shown in Figures 3 and 4, the 1-piece fastener 27 consists of a feed path 28, a chain spreader 85, a slider feed unit 86, and a belt edge locator 87.

The chain spreader 85 is mounted on a vertical mounting plate 65 and inclined along a feed path 29 advancing 30 downward in the direction in which the chain 10 is fed. As shown in detail in Figures 8 and 9, the chain spreader 85 includes a chain guide 88 through which the feed path 29 passes and an arm 89 pivotally mounted by a pin 90 on a mounting plate 65 above the chain guide 88. At the front end of the arm 89, two levers 91, 91 are pivotally mounted laterally by means of pivot pins 92, 92 (Fig. 10). The levers 91, 91 have two downwardly directed pins 93, 93 which normally contact the upper surface of the rows of coupling members β 77144 12 between the arm 89 of the chain and the chain guide 88 under the force of elastic force 94. Thus, when any gap 13 free of the coupling members between successive lengths of the coupling members 12 reaches the pins 93, 93, these move downwards from the coupling members free space 13 under the influence of the force of the spring 94. The rods 93, 93 are then lifted out of the gap 13 by means of a fourth cylinder 95 which presses down the rear end of the arm 89 against the resilience of the spring 94. Typically, the fire of the tension spring 93a engages the pins 93, 93 facing each other, which spring is connected to opposite ends of the respective levers 91, 91, as shown in Fig. 10. The second lever 96 is mounted vertically pivotally by a pivot pin 97 on a bracket 65a mounted on the mounting plate 65. -15 tu above arm 89. Lever 96 has a front wedge 98 directed downwardly between the pins 93, 93. The lever 96 is effectively connected by a pin 100 to a bracket 65b attached to the piston rod of the fifth media cylinder 99, which causes the wedge 98 to move to a lower position 20 between the pins 93, 93 or to an upper position above the pins 93, 93.

When the pins 93, 93 come to one of the spacings 13 free of the coupling members, they protrude downwards therein. At present, the passage of the chain 10 is stopped in response to such a downward movement of the pins 93, 25 93, as observed by the arrangement shown in Fig. 9. More specifically, the detector plate 101 is positioned laterally at the rear end of the arm 89 for substantially horizontal movement around the pin 102, the detector plate 101 being normally forced by the spring 103 to move toward the arm 89. The detector plate 101 has a protrusion or shoulder 104 that extends upwardly and is positioned adjacent the arm 89 and an inclined cam surface 105 that progressively extends laterally above the lever 96. The detector rod 106 protrudes from the detector plate 101 away from the cam surface 105, and its end is usually in contact with the sensor 107. As the pins 93, 93 are moved downwardly into the gap 13, the rear end of the arm 89 is therefore raised until it is released from the shoulder 104, after which the indicator plate

II

9 77144 101 is turned to the right (Fig. 9). Now, the detector rod 106 disengages from the sensor 107, which produces an electrical signal indicating that the pins 93, 93 are depressed between 13. The wedge 98 is then lowered to spread the pins 93, 93 against the tension of the tension spring 93a (Fig. 11). to separate into separate rows from the front end of the gap 13.

When the movement of the chain 10 is interrupted, the brake mechanism 39 of the guide roller device 31 is caused to lock the chain 10, which is now held taut between the guide roller device 31 and the output roller device 33, so that the slider can be easily placed on the rows of clutch members 12.

The slider feed unit 86 is located below the rear end of the chain spreader 85 and is movably supported at an angle 15 by a horizontal shaft 108 mounted on a column 109 vertically positioned on the machine base 30. As shown in Fig. 8, the slider holder 110 is fixedly located above the shaft 108 and t a holder 111 is rotatably mounted on the shaft 108 to hold the pull tab 19 of the slider 20 against the slider holder 110, the holder 111 having a through hole 112. The lever 114 mounted pivotally mounted on the pin 115 on the slider holder 110 has a locking tip 113 on the pull tab 19 for gripping the hole 20 through the hole 112 in the holder 111. The locking tip 113 is forced into the hole 20 in the traction strip 19 by means of a sixth medium cylinder 116, the piston rod 117 of which acts on the lever 114 via a steel ball 118. Usually, the locking tip 113 is forced to move in the direction out of the hole 20 of the tension strip 30 under the resilience of the tension spring 119, which tension spring acts between the slider holder 110 and the lever 114.

The sliders 17 are sequentially fed from the chute 82 (Fig. 3) to the slider holder 110. The shaft 108 moves back and forth 35 at an angle of about 90 ° to move the slider holder 110 between substantially horizontal and vertical positions, providing angular movement of the shaft 108 via a gear (not shown). attached 10,771 44 to a shaft 108 and engaging a rack (not shown) driven by a fluid cylinder (not shown). The slider holder 110 receives one Liu piece 17 from the chute 82 at a time, with the edges 18 of the slider 17 facing upward, as shown in Figure 10, when the slider holder 110 is in a horizontal position (Figure 8). When the slider holder is turned to a vertical position, in order to place the slider 17 in the space 13 free of the coupling members, applied as shown in Fig. 11 by pins 93, the edges 18 of the slider 17 are directed towards the front end of the next interconnected rows of coupling members 12. positioned parallel to the chain 10.

The belt edge positioner 87 is positioned above the feed path 29 between the chain spreader 85 and the feed roller device 32, as shown in Figure 3. The belt edge positioner 87 comprises a substantially horizontal rod 121 attached to the piston rod 20 of the seventh medium cylinder 120 (Figure 12). which cylinder is mounted on the mounting plate 65. The horizontal bar 121 extends substantially perpendicular to the feed path 29 and is movable downwardly by the seventh media cylinder 120 to press it into contact with the chain 10 (Fig. 13).

As shown in Fig. 16, the bottom stop fastener and chain breaker 28 essentially comprises a frame 122 mounted on the mounting plate 65, a punch 123, and a cutter 124 disposed vertically on the frame 122 and operable by an eighth medium cylinder 30 mounted on the mounting plate 85. The punch 123 is located a second cutter 126 having cutting blades 127, one of which cuts the bottom stop blank wire 147 when pressed down, which is fed horizontally under the punch 123, as shown in Fig. 17. A cut piece of the blank cut with the cutter blade 127 is formed into a bottom stop 21 by a descending punch. 123 and the wire bender 128 positioned below it, as shown in Fig. 18. The base stop 21 formed thereafter is passed through the coupling members 12.

II

11 77144 to the front end of the interconnected rows by a punch 123 which is continuously depressed while the chain 10 is cut transversely across the gap 13 free of the clutch members adjacent the front end 5 of the interconnected rows 12.

As shown in Figs. 3, 4, 19, and 20, the vertical stop bar 130 is angularly mounted at the end of the lever 131 mounted on the mounting plate 65 by the pin 132. The counter bar 130 has an upper end that is normally held Liu-10 as shown by the interconnected members 12. against the lower surface of the rows, and the lower end of the stop bar is usually in contact with the sensor 133. When the gap 13 free of the coupling members of the chain 10 reaches the upper end of the counter rod 130, this counter rod 130 moves upwards under the action of a spring 144, which spring acts to push the lever 131 into the gap 13. The upper end of the stop rod 130 moves slightly in the direction of travel of the chain 10 due to the movement of the chain 10, whereby the lower end of the stop rod 130 is released from the sensor 133, which provides a signal to stop the motor 67. Mounted on the mounting plate 65 is a ninth media cylinder 145 which acts on the lever 131 to lower the counter bar 130 from the gap 13 as the chain 10 is fed forward. Lever 131 has an adjustment bolt 146 for adjusting the distance at which the stop bar 130 is vertically displaceable.

25 As shown in Figs. The corn branches 137, 135 have guide grooves 143, 134, respectively, which open downwards and are aligned with the feed path 29. The clutch member guide 138 is usually forced to rotate clockwise (Figures 19 and 21) about the shaft 136 under the tension of a spring 139 which acts on the rear end of the clutch member guide 138. The bracket 50, in which the upper feed roller 48 is rotatably mounted, has a vertical bolt 140 vertically aligned with the rear guide arm 135 for depressing this rear guide arm 12 771 44 when the upper feed roller 48 is lowered. When the upper feed roller 48 is raised via the first fluid cylinder 23 (Fig. 3), the clutch member guide 138 rotates clockwise under the action of a spring 139, causing the rear guide branch 135 to rise and the front guide branch 137 to lower. The bracket 53, in which the lower feed roller 49 is rotatably mounted, has an upper guide base 142 for the clutch members with an upwardly open guide groove 141 aligned with the feed path 29. When the front guide arm 137 of the switch member guide 138 138 is lowered, the guide groove 143 herein and the guide groove 141 in the switch member base 142 together define a guide slot (Fig. 21) to guide the interconnected rows of switch members 12 therethrough.

As shown in Fig. 23, the lower discharge roller 62 has two axially spaced roller portions 62a, 62b of equal diameter and aligned with the upper rollers 61, 61, respectively. Since the levers 63, 63 are articulated and loosely connected to the piston rod of the cylinder 66, the upper rollers 61, 61 are vertically movable away from the respective roller portions 62a, 62b of the lower roller 62 to define a gap 83 between the second upper roller 61 and the lower roller portion 62b. greater than the gap 84 between the second upper roller 61 25 and the lower roller portion 62a. The wider gap 83 allows the folded slit edge 14 of the zipper 22 to run smoothly between the upper roller 61 and the lower roller portion 62b.

The machine thus constructed operates as follows: Continuous drawing of the chain 10 with its split edges 14 is fed 30 along the feed path 29 first to the split edge folder 26, where the split edge 14 is folded twice by a guide plate 47, while the chain 10 is guided by a guide roller device 31. through a spreader 85 by a feed roller device 32, wherein the pins 35 93, 93 contact the upper surface of the rows of coupling members 12 interconnected, as shown in Figure 10. During this time, the slider 17 is mounted on the 1-piece holder 110, positioned

II

13 771 44 18 are located upwards. The slider 17 is securely held in place by a locking tip 113 which engages a hole 20 in the drawbar box. When the gap 13 free of the coupling members reaches the pins 93, 93, they protrude downwards into the gap 13.

As the chain 10 travels continuously, the pins 93, 93 rest against the front end of the successive lengths of the clutch members 12, after which the clutch plate 73 is detached from the clutch plate 71, the chain 10 is stopped and the brake mechanism 39 is actuated in response to a signal 10 from the sensor 107. under. The fifth cylinder 99 is then actuated to retract its piston rod, after which the wedge 98 is lowered to extend the pins 93, 93 apart to open the gap 13 and to extend the front end of the rows of clutch members 12, as shown in Figure 11. The slider feed unit 86 is turned counterclockwise to position the slider 17 in between 13. Retraction of the piston rod of the cylinder 99 causes the lever 96 to contact the cam surface 105 and force the detector plate 101 to rotate against the tension of the spring 103 until the detector rod 106 contacts the sensor 107, as shown in Figure 9. The fourth cylinder 95 is then actuated. to extend the piston rod, after which the arm 89 is rotated counterclockwise (Fig. 8) around the pin 90 against the tension of the spring 94, thereby moving the pins 25 93, 93 upwards away from the free space 13 of the coupling members. Now opposite inner edges of the coupling strips 11, 11 17 through the slots therein. To ensure that the edges of the clutch strips are positioned within the slider 17, the rod 121 of the edge positioner 87 is lowered to press the chain 10 so that the edges of the strip that may have touched the top surface of the slider will enter the slider 17, as shown in Figures 12 and 13. Simultaneously, the upper feed roller 48 is lowered, to bring the chain 10 35 between the upper and lower feed rollers 48, 49 and to bring the chain 10 between the upper and lower output rollers 61, 62. Since the rear guide arm 135 of the switch member guide 138 is lowered, the guide groove 134 evenly guides the rows of switch members 12, as shown in Fig. 19.

The rack 80 (Fig. 7) is then acted upon by a third cylinder 81 to rotate the lower output roller 62 at certain angular intervals against the braking force provided by the brake mechanism 39. The lower feed roller 49 is also rotated via a chain 55 in synchronism with the lower output roller 62. The chain 10 is moved slightly to cause the rows of clutch members 12 to pass inside the slider 17 between the open edges 18, 18, after which the slider 17 is placed on top of the rows of clutch members 12.

The brake mechanism 39 is then stopped and the sixth cylinder 116 is deactivated, to move the locking tip 113 away from the slider holder 110, to release the slider 15 17, as shown in Fig. 15. The upper feed roller 48 is raised by the first cylinder 23 and the clutch plate 73 is contacted as a result, the motor 32 will drive the lower output roller 62 via the drive mechanism 68 20 (Fig. 7) to feed the chain 10 with the slider 17 mounted thereon. When the front end of the rows of clutch members 12 contacts the stop bar 130, the lower removal roller 62 stops. At the same time, the slider 17 in the chain 10 has moved past the raised rear guide arm 25 135. Since the front guide branch 137 is lowered, the rows of clutch members 12 are guided evenly by the guide grooves 143, 141. The bottom stop is then secured and the chain 10 is severed by the bottom stop fastener and the chain cutter 28 in response to operation of the eighth media cylinder 30 125. The upper feed and discharge rollers 48 are now lowered. 61. The severed zipper is then removed by the discharge roller device 33. The chain 10 is also fed by the feed roller device 32, during which time the front guide leg 137 is in the upper position, allowing the slider 17 to move towards the discharge roller device 33.

When the machine is operating, the feed roller device 32 grips and conveys the rows of clutch members 12 so that the chain 10 can be fed safely forward despite the fact that

II

is 7714 4 the split edge 14 is sewn to the second clutch strip 11. Since the chain 10 is held under tension by the brake mechanism 39 when mounting the slider 17, the edges of the strips, when held taut, are pressed down by the rod 121 5 and securely inserted into the slider 17. The clutch member guide 138 can precisely control the rows of clutch members 12 at all times, alternatively with the control arms 135, 137, while allowing the slider 17 to pass through them. The removal roller device 33 can remove the finished zipper 22 securely, 10 without any adhesion, because the slit edge 14 can pass smoothly through the larger gap 83 between the upper roller 61 and the lower roller portion 62b.

Although various minor modifications may be proposed by those skilled in the art, it will be apparent that all such embodiments are within the scope of the invention within the scope of the following claims.
