According to a second aspect of this invention, in removing cut legs remaining on fastener tapes, there is provided an other method for forming element-free space sections of a slide fastener chain comprising the steps of, gripping only the cut legs at both side ends of space sections by grippers to draw-out and remove the cut of both side ends in the direction orthogonal to thefastener tape faces, and scraping off the remaining cut legs by means of a rotary cutter and a rotary tumbler for leading the space sections toward the rotary cutter to remove the cut legs from the fastener tapes.
According to this invention, the heads and the cul legs of the coupling elements are respectively removed in the different processes. Then, the heads and the cut legs of the coupling elements are respectively drawn-out in the .
direction reverse to the direction of permeating a molten coupling element into the fastener tapes. Therefore, in this melhod, the heads and the cut legs of the coupling elements can be easily removed by the small force without damaging the fastener tapes and without causing the chain crack to form the element-free space sections efficiently.

DETAIL DESCRIPTION OF THE P~ KREU EMBODIMENT
An embodiment of this invention will be described with reference lo the drawing figures.
Referring now to FIG. 1 ,there is shown an apparatus for carrying out a space section forming method of this invenlion comprising a coupling element punching means 10 ,a first coupling element leg removing means 20 ,and a second coupling element leg removing means 30.
Right and left fastener stringers are supplied at the interengaged state to remove heads 3 of interengaged coupling elements 2 in the coupling element punching means 10 as shown in FIG. 2.
Referring to FIG. 2 to FIG. 4 showing the orders for removing heads 3 of coupling elements 2 from fastener tapes 8 ,a slide fastener chain 1 is guided bya pair of right and left chain guides 14. When space sections of the slide fastener chain 1 reaches to the coupling element punching means 10, the transferof the fastener chain is stopped and pressure pads 15, 1~ are ascended from apertures of the chain guides 14. Then, space sections 9 of fastener tapes 8 are held between the chain guides 14. The heads 3 of the coupling elements 2 are pressed by means of a descending punch 11 and a pair of ascending cutters 12, 12 to cut lower forked legs 7 of the coupling elemenls 2 as shown in FIG. 3.Nextly, the cut head 6 of the individual coupling element 2 is held between the punch 11 and a knock-out rod 13 and ascended lo remove the heads 3 and lhe upper 2~7922 .
legs of the coupling elements. 1'he knock-out rod 13 has thesame lenglh as a space section 9 and disposed belween the cutters 12. 1`he knock-oul rod 13 together with the cutters 12 is ascended to remove and discharge the heads 6 toward the outside as shown in FIG. 4. The slide fastenerchain 1 is transferredinto the first coupling element leg removing means 20 of the following process at the state that the cut legs are remained in stringer cores 8 as shown in FIG. 8.
FIG. 5 and FIG. 6 show the state for removing the cut legs 5 disposed in the both side ends of the space section 9 in the first coupling element leg removing means 20. When the slide fastener chain 1 transferred from the coupling element punching means 10 being guided by a chain guide 16 reaches to the first coupling element leg removing means 20, it is stopped and a space section determining member 21 descends from the upward position to carry out thepositioning of the slide fastener chain 1, as shown in FIG. 5. The chain guide 16 is disposed contacting the back face of the slide fastener chain 1 and is provided with a pair of apertures 24, 24 al the position corresponding to the both ends of the space section. A center guide 22 is set under lhe chain guide 16 and is ascended through working apertures 24 as shown in FIG. 5 and FIG. 6.
The projected both ends of the center guide 22 are passed through the punched gaps of the heads 3 of the coupling elements in a slide fastener chain 1 and engaged in a positioning groove 25 which is formed in the back face of the spacesection determining member 21, so as to carry out the positioning. Right and left grippers 23, 23 are disposed on the both sides of the center guide 22 and ascended as shown by arrows in FIG. 6. After the grippers are contacted to the back faces of the fastener tape 8, they are moved toward each other to hold cut legs 5 at both side ends of space section 9 between the sides of the center guide 22 and the grippers 23, 23. The cut legs 5 are drawn-out downwardly in the direction orthogonal to the surfaces of the slide fastener tapes 8 as shown 20~922 .
in FIG. 9, while holding the cul legs 5 between lhe center guide 22 and the grippers 23. In the first coupling leg element removing means 20, all cul legs 4, 5 adhered to the fastener tapes 8 are removed at one time to form the space section 9. Then, the all cut legs 4, 5 are held between a flat plate of center guide 22 and grippers having the approximate same length as the space section 9 and thereby are drawn-out downwardly. The working aperatures 24 of the chain guides 16 are required to be punched al the approximate same length as the spacesection 9.
The slide fastener chain 1 in which the cul legs 5 are removed at the both side ends of the space sections 9, is transferred to the second coupling leg element removing means 30 by guide rollers. The second removing means 30 servesto scrape off and remove all of remaining cut legs 4 by means of a rotary cutler31 and a rotary tumbler 33 as shown in FIG. 1 and FIG. 7.
The rotary tumbler 33 has the same elliptic shape as the conventional construction and are provided with a circular deteclor 36 for space section terminal which is always urged outwardly by a spring 34. The slide fastener chain 1 which is processed in the first coupling element removing means 20, is always moved and guided along the space section terminal detector 36. ~len the head-removed portion of the space section 9 reaches to the detector, lhe space section terminal detector 36 is projected to the space section by the spring 34 as shown in FIG. 7, so that a tip stopper 35 is contacted with the heads of the coupling elements. Then, a notch (not shown) for preventing the rotation of therotary tumbler 33 by a pulling force of the slide fastener chain 1 is released to rotate the rotary tumbler 34, so that the slide fastener chain 1 approaches to the rotary cutter 31. The remaining cut legs 4 are scraped off and removed by the blades 32 of the rotary cutter 31 as shown in FIG. 10. Since the cut legs 5 at the both side ends of the space section 9 are pre-removed from lhe slide fastener chain 1, the cut legs 4 are easily removed without requirement of 2~7922 fine adjustment and without damaging the coupling elements 2 arranged adjacent to the space section.
As described, according to this invention, the heads and the cut legs of the coupling elements are respectively removed in the different processes, so that the coupling elements can be efficiently and naturally removed from the fastener tapes without damaging the fastener tapes.
The conventional one method of forming element-free space sections in a slide fastener chain provided with synthetic resin coupling elements is disclosed for example, in JP, U no.55-109410 (Japanese unexamined utility Model Publication). With this citation, there is known the method of forming space sections free of coupling elements in a slide fastener chain comprising the step of, putting the slide fastener chain on a die provided with a through hole of the element width at the center posilion, descending a punch provided with two steps on side faces from an upward position toward heads of coupling elements to punch the heads, and still more descending the punch to catch and remove legs remained in the fastener tape by the punch step.
