SHEEI 1 BF 2 FIG.1 T Es E METHOD AND APPARATUS FOR REMOVING INTERLOCKING ELEMENTS FROM SLIDE FASTENER CHAIN BACKGROUND OF THE INVENTION This invention relates to the provision ofa slide fastener stringer which has end portions devoid of interlocking fastener elements, more particularly to a method and apparatus for removing fastener elements at predetermined intervals from a slide fastener chain of substantially endless length thereby providing herein alternate element-containing and element-free sections.
To simpify and facilitate the assembling and finishing of slide fasteners, it is nowadays the common practice of the slide fastener manufacturers to work on a continuous chain of slide fastener stringers carrying thereon uninterrupted interengaged rows of interlocking elements rather than on separated individual fastener stringers. It has been the usual practice to provide element-free or space sections in the fasteners chain at predetermined intervals thereon for mounting sliders and end stops and thereafter to cut the chain into individual product length.
There have been proposed various methods and apparatus to this end for removing a length of interlocking elements from a slide fastener chain, but none of them have been found completely satisfactory in removing the elements alone from their carrier tapes to which they are firmly secured. Difficulties have been experienced in cutting the elements off exactly at the coupling heads thereof, and failing this would often cause damage to the woven or sewn threads or even the tape web. This was more critical in the case ofa fastener chain carrying rows of continuous fastener elements in a coil or meandering form having a reinforcing cord inserted between the arm portions'of the elements, where the cord is susceptible to damage in contact with the cutter blades. If the elements were not cut off completely or at desired position, it would render the subsequent removal of element debris so much difficult.
SUMMARY OF THE INVENTION With a view to eliminating the above difficulties encountered with the conventional methods and apparatus, the present invention has for its object to provide a novel method for removing a desired length of interlocking fastener elements from a continuous slide fastener chain without any damage to adjacent woven or sewn threads, reinforcing cords or tape web and an apparatus for effectively carrying this method into practlce.
It is a more specific object of the invention to provide a novel method and apparatus for removal of a length of fastener elements which ensures that the elements to be removed are held in correct position relative to the path of a cutting or severing means so as to cut them off exactly in their coupling head portions and further that the removal of the remaining portions or debris of the elements is effected with utmost ease, resulting in the provision of clean element-free or space sections as desired on the fastener chain.
These and other objects and features of the invention will appear clear from the following detailed description taken in conjunction with the accompnaying drawings which illustrate by way of example a preferred embodiment and in which like reference characters refer to like parts through the several views.
BRIEF DESCRIPTION OF THE DRAWINGS DESCRIPTION OF THE PREFERRED EMBODIMENT In accordance with the invention, there is provided a method for removing fastener elements from a slide fastener chain consisting of a pair of stringer tapes carrying thereon uninterrupted rows of continuous fastener elements in interlocked relation each of which elements having a coupling head and a base portion merging into adjoining element, which method comprises the steps of positioning a length of interlocked elements with their coupling heads registered with the path of a cutting means; gripping the base portions of said elements in each row to restrict free movement thereof; severing the interengaged coupling heads; and pulling said base portions while being gripped, outwardly apart from their respective stringer tapes to remove the remaining debris of elements thereby leaving thereat an element-free section.
Referring now to the drawings and FIG. 1 in particular, there is shown a segment of a slide fastener chain F which consists of a pair of opposed stringer tapes T carrying along their respective inner edges a row of interlocking fastener elements E. More specifically, the fastener chain F is provided with a predetermined length L of an element-free or space sections alternating with an element-containing section Es. This element-free section is utilized for the assembling of a slider and end stops (top and bottom stops) on the fastener chain F in the known manner.
The provision of the element-free or space section S is effected by the apparatus which is shown by way of example only in the drawings and which is tailored to arry the bove described method into practice. The element removal apparatus generally designated 10 comprises a stationary anvil 11 having a die groove 12 and a vertically reciprocating punch head 13 having a downwardly projecting punch 14 which constitutes with the die grove 12 a coacting die cutter for severing the coupling heads Ea of the fastener elements E. The anvil 11 has seats lla on opposite sides of the die groove 12 for resting thereon the arm portions Ec of the elements as shown. The apparatus 10 further comprises first or male gripper means 15 and second or female gripper means 16 on opposite sides of the anvil 11.
The male grippers 15 have gripping jaws 15a formed longitudinally of their respective inner edges and further have downwardly inclined surfaces 15b merging into the jaws 15a. The inclined surfaces 15b are utilized to lift the stringer tapes T thereon away from the rows of elements E so as to permit the gripping jaws 15a to reach and grip the base or connecting portions Eb of the elements E. The female grippers 16 are each provided in the longitudinal edge therof with an elongate recess 16a for receiving the base portions Eb and retaining the same in position during the gripping action of the male gripper means 15.
The method for providing the space sections in the fastener chain F according to the invention will now be described more fully in conjunction with the operation of the foregoing apparatus 10. The fastener chain F is positioned on the apparatus with its rows of elements E seated on the anvil l1 and with its stringer tapes T lifted upwardly away from the elementsE as shown in FIG. 2. This is the first operating phase of the apparatus 10 wherein the elements E as interengaged are laid flat on the anvil 11, more specifically with their arm portions Ec borne against the seats 11a, with their coupling heads Ea exposed in the opening of the die groove 12 and with their base portions Eh projecting beyond the seats 11a and received in the recesses 16a of the female grippers 16. This is followed by the second operating phase, as shown in FIG. 3, wherein the male grippers 15 have descended and gripped the elements E at their base portions Eb in cooperation with the female grippers 16. With the rows of elements E thus firmly gripped and stably retained in position, the punch 14 begins to descend and 'cuts the coupling heads Ea alone as it thrusts through the die groove 12 as shown in FIG. 4, which constitutes the third operating phase. After the coupling heads Eahave been thus cut off, the remaining debris including arm and base portions of the elements E are now removed from the fastener chain F in the fourth or final operating phase wherein the male and female grippers 15, 16 still gripping the base portions Eb begin to retract sidewise away from the anvil 11 taking with them the residual element debris apart from the reinforcing cord 18 and weaving threads 19 which have secured the elements E to the tapes T. The punch 14 will then ascent, leaving a space section such as shown in FIG. 1, which section presents a clean, undamagedelement-free tape portion suitable for smooth assembling of the various fastener parts.
While the invention has been described as to a preferred embodiment, it will-be understood that various changes, substitutions or modifications may be made in the specific form and construction herein advanced, without departing from the scope of the appended slide fastener chain having a pair of stringer tapes car-' an anvil having a die groove operatively associated with I claims.
