Abstract

The invention discloses a weaving method capable of separating main yarn and waste yarn in a flat knitting machine. The used flat knitting machine at least comprises a pair of needle beds which are arranged in the front and at the back, needle beds have a front-to-back needle transferring function, before connection lines of the main yarn and the waste yarn are woven, all front bed coils are turned to the rear bed, all subsequently woven threads and coils of the front bed are turned to the rear bed, and then weaving is conducted on the rear bed only. Connection lines of the main yarn and the waste yarn can be exposed to the outside through needle transferring, the yarn is free from twining through intermittent weaving on the rear bed, and the main yarn and the waste yarn can be separated easily.

Description

The weaving manner that in a kind of horizontal volume machine, main refuse yarn separates

Technical field

The invention belongs to the technical field of horizontal volume machine, especially related to the weaving manner that in a kind of horizontal volume machine, main refuse yarn separates.

Background technology

In braided fabric, the yarn that forms braided fabric integral body is called main yarn, and some need to remove no yarn and be called refuse yarn after the braided fabric moulding.Be illustrated in figure 1 the connected mode of existing master, refuse yarn, it directly completes by lopping, namely between main yarn 3 and refuse yarn 2, connects by yarn 1, because yarn 1 is the yarn of a lopping, and with master, refuse yarn, be connected simultaneously, therefore main yarn 3 is separated with refuse yarn 2, yarn 1 must be detached.And in the process that detaches yarn 1, owing to 1 being the yarn of a lopping, so density is very tight, simultaneously due to master, the equal tangle up of refuse yarn, therefore in the process of tearing open, often need the power that expense is very large, and can damage fabric simultaneously.

Summary of the invention

The purpose of this invention is to provide the weaving manner that in a kind of horizontal volume machine, main refuse yarn separates, thereby solve the problems of the technologies described above.

For this reason, adopt following technical scheme: before and after a pair of needle-bar before and after the weaving manner that in a kind of horizontal volume machine, main refuse yarn separates, the horizontal volume machine of use have at least, needle-bar have, turn over the pin function; It is characterized in that: after the braiding multirow, last column is designated as to N capable, from after this journey, carrying out following steps:

1. after braiding N was capable, the head right lateral, be not with the yarn mouth, and all external crucible coils are turned over to rear bed;

2. in the capable braiding of N+1, the head left lateral, band yarn mouth, what external crucible hung the empty pin of order one pin, hang the order weaving manner, lopping at the empty knitting pin of rear bed simultaneously weaves, and it is staggered to hang order and lopping, namely when the external crucible pin hangs order with it before and after corresponding rear bed pin empty needle, when external crucible pin empty needle with it before and after rear corresponding pin lopping; Afterwards all external crucibles being hung to order turns over to rear bed;

3. in the capable braiding of N+2, the head right lateral, be with the yarn mouth, carries out full bed braiding at rear bed;

4. in the capable braiding of N+3, the head left lateral, be with the yarn mouth, carries out full bed braiding at rear bed.

After braiding N was capable, the head motion of turning right, turned over all external crucible coils to rear bed, so just can guarantee that the line be removed can not be crushed in the coil group of front and back bed.In step N+1, adopt external crucible to hang the purpose mode, can widen coil, to facilitate the disengaging of main yarn and refuse yarn.In step N+2 and N+3, external crucible does not carry out any braid movement, and carries out the lopping braiding at rear bed.After above braid movement, when main yarn is separated with refuse yarn, as long as the coil formed at rear bed in step N+2 and N+3 is extracted out, namely main yarn can be separated with refuse yarn.

The accompanying drawing explanation

Fig. 1 is the main refuse yarn separate mode schematic diagram of prior art.

Fig. 2 is the useless yarn weaving manner schematic diagram separated of master of the present invention.

Fig. 3 is the braid method signal block diagram of the present embodiment.

The specific embodiment

Referring to accompanying drawing.Wherein " F " means external crucible, and " B " means rear bed, and " ← " means that head is toward left movement, " → " means the head motion of turning right, and " V " means to hang the purpose weaving manner, the weaving manner of " zero " expression lopping, " ↑ " means the coil of external crucible is moved to rear bed, and " | " means empty needle.Before and after having, a pair of needle-bar before and after the horizontal volume facility that the present embodiment is used have, needle-bar turn over the pin function.After the braiding multirow, last column is designated as to N capable, from after this journey, weaving with braid method of the present invention; Carry out following steps:

By between main yarn 3 and refuse yarn 2, passing through two yarns 4 and 5, do not form coil, coil 4 both can have been pushed down main yarn 3 not separated with refuse yarn 2 with 5 like this, simultaneously when main yarn 3 is separated with refuse yarn 2, as long as line yarn 4 and 5 is detached.

Before the connecting line at braiding master, refuse yarn, all external crucible coils are turned over to rear bed, and turn over to rear bed at line and the coil of all braidings of follow-up external crucible, then only at rear bed, weave.By turning over pin, the connecting line of master, refuse yarn can be exposed to outside, and by only in the braiding of rear bed unlooped, unlikely yarn is wound around, easily separate main, refuse yarn.

Claims

1. before and after having, a pair of needle-bar before and after the weaving manner that in a horizontal volume machine, main refuse yarn separates, the horizontal volume machine of use have at least, needle-bar turn over the pin function; It is characterized in that: after the braiding multirow, last column is designated as to N capable, from after this journey, carrying out following steps:

1) after braiding N was capable, the head right lateral, be not with the yarn mouth, and all external crucible coils are turned over to rear bed;

2) in the capable braiding of N+1, the head left lateral, band yarn mouth, what external crucible hung the empty pin of order one pin, hang the order weaving manner, lopping at the empty knitting pin of rear bed simultaneously weaves, and it is staggered to hang order and lopping, namely when the external crucible pin hangs order with it before and after corresponding rear bed pin empty needle, when external crucible pin empty needle with it before and after rear corresponding pin lopping; Afterwards all external crucibles being hung to order turns over to rear bed;

3) in the capable braiding of N+2, the head right lateral, band yarn mouth, carry out full bed braiding at rear bed;

4) in the capable braiding of N+3, the head left lateral, band yarn mouth, carry out full bed braiding at rear bed.
