Problems solved by technology

[0011] However, for JP-UM-B-56-16088, JP-A-8-56713 and JP-B-54-21781, when knitting the core thread to the joint part of the zipper tape, due to the The space is narrow, the needles form two wales of the same joint part, the core wire and the needles are easy to interfere with each other except that the core wire becomes thicker, and it is difficult for the core wire to pass smoothly between the needles, resulting in the core wire contacts and often damages the needle

Embodiment Construction

[0021] Preferred embodiments of the present invention will be described with reference to the corresponding drawings.

[0022] figure 1 and 2 are a perspective view and a side view showing the fastener element row formed by the production machine of the warp-knitted fastener tape T and its knitting action according to the first embodiment of the present invention. In this embodiment, the body of the production machine may be a single raschel machine of the normal vertical needle bed type, a crochet machine, or a tricot machine. Accordingly, their detailed parts are omitted from the drawings.

[0023] In these figures, reference numeral 1 designates a needle bed (referred to herein as needles) for slidably accommodating a plurality of knitting needles 2 arranged in parallel along respective sliding grooves, also called needle grooves 1a. Reference 3 refers to the knitting yarn used for the ground weave. Reference 4 indicates a knitting yarn guide for guiding the respective ...

Abstract

The machine for producing the warp knitted belt of zip fastener knits the warp knitted belt while knitting the core thread continuously along one side of the belt. The machine includes one single needle bed with sliding flutes for knitting needles to slide in parallel, one knitting yarn carrier capable of swinging and shifting transversely, one first core thread guiding finger for guiding the corethread, and one second core thread guiding finger set in the knitting path of the core thread at the knitting fell of the needle bed to guide the core thread.

Description

technical field [0001] The present invention relates to a production machine for warp-knitted fastener tapes for slide fasteners, which knits a tape and at the same time knits a core thread along one side longitudinal end portion of the fastener tape forming a warp-knitted weave. Background technique [0002] A kind of warp-knitted zipper tape for zipper, wherein when knitting the zipper of warp-knitted tissue, a core thread is knitted at the same time, and this zipper tape is disclosed in for example JP-UM-B-56-16088 and JP-UM-B-56-16088 and JP- A-8-56713. [0003] JP-UM-B-56-16088 discloses a first embodiment in which the tape main body is knitted into a double-knit by multiple rows of needles. The element connecting part connected to the connecting part is knitted by multiple rows of needles in a double-sided tricot weave, and forms an expansion part as a way of wrapping around the core material. The second embodiment disclosed in JP-UM-B-56-16088 includes the front sid...
