[Problems to be solved by the device]

 When performing argyle knitting with this conventional carriage, only the knitting needles corresponding to the borders (outlines) of the pattern remain at the rear knitting position B, and the other knitting needles are moved to the front knitting position C. After that, the color arrangement yarn is laid over the knitting needle group at the front knitting position C. At that time, the knitting needle at the rear knitting position B was largely pulled out by hand to the front knitting position C or further to the front so that no breakage holes (longitudinal cracks) were formed at the boundaries of the pattern knitted with the color arrangement yarn. After that, it was necessary to hang the color-arranged yarns on the drawn knitting needles so that the yarns intersect each other.

However, since the knitting needle at the rear knitting position B is sandwiched between the knitting needles at the front knitting position C on both left and right sides of the knitting needle, the knitting needle is greatly retracted, so that the knitting needle is caught between the knitting needles. It is troublesome to pull out a single knitting needle that is retracted, but it has to be done at each boundary of the patterns on each stage, and also at each stage, which is very troublesome for the user. It was a troublesome task.

An object of the present invention is to eliminate the troublesome work of manually pulling out the knitting needle retracted to the rear knitting position to the front when performing the argyle knitting or the intarsia knitting. An object of the present invention is to provide a carriage that can perform intarsia knitting quickly and efficiently and can be used not only for hand knitting machines but also for industrial knitting machines.

[0006]

[Means for Solving the Problems]

 In the carriage according to the present invention, the left and right electromagnetic needle selection parts that attract the knitting needle butt by the magnetic force of the electromagnet and bias it back and forth, and the knitting needle bat that is biased forward and backward by the electromagnetic needle selection part in the front guide passage and the rear guide passage. In addition to the left and right main knitting cams, which can be distributed separately to the first front knitting position C and the rear knitting position B, which are located forward of the position where the bellows are pulled out, the following cams are further provided.

That is, an inactive position for guiding the knitting needle butt from the rear knitting path to the rear knitting position B as it is, and an action for guiding the knitting needle butt from the rear knitting path to the first front knitting position C. An intarsia cam that is switchable to a position and displaceable is provided, and a front derivation auxiliary cam that guides the knitting needle butt from the front knitting passage to a second front knitting position C ′ slightly ahead of the first front knitting position C. It is a thing.

This front lead-out auxiliary cam has a first position where the knitting needle butt from the front knitting passage can be guided and led out to the second front knitting position C ′, and a knitting needle butt from the front knitting passage is proposed. The second front knitting position C'can be switched to the second position which can be led to the third front knitting position D further forward.

[0009]

[Action]

 When the intarsia cam is set to the inoperative position and the front lead-out auxiliary cam is set to the first position, the knitting needle butt that has passed through the rear knitting passage is led out to the rear knitting position B as it is, and passes through the front knitting passage. The knitting needle is guided to the second front knitting position C ′ by the front drawing auxiliary cam. That is, the knitting needle is roughly divided into the rear knitting position B and the second front knitting position C '.

When the intarsia cam is set to the operating position and the front lead-out auxiliary cam is set to the first position, the knitting needle butt that has passed through the rear knitting passage is guided by the intarsia cam and is set to the first front knitting position C. The knitting needle guided to the front knitting path is guided to the second front knitting position C ′ by the front drawing auxiliary cam. That is, the knitting needle is divided into a first front knitting position C and a second front knitting position C ', which are close to each other as shown in FIG. Therefore, when performing argyle knitting or intarsia knitting, if the knitting needles of the second front knitting position C'correspond to the boundaries of the pattern and the color arrangement yarns are laid over the knitting needle group of the first front knitting position C. Even if the knitting needle at the second front knitting position C ′ is not moved, the color-arranged yarn is hung on the knitting needle at the second front knitting position C ′ so that the yarns are twisted and crossed at the adjacent positions to form a pattern. Vertical cracks can be prevented.

When the intarsia cam is set to the operating position and the front lead-out auxiliary cam is set to the second position, the knitting needle butt that has passed through the rear knitting passage is guided by the intarsia cam and is set to the first front knitting position C. The knitting needle guided to the front knitting path is guided to the third front knitting position D by the front drawing auxiliary cam. That is, the knitting needle is divided into a first front knitting position C and a third front knitting position D, as shown in FIG. Therefore, assuming that the knitting needle at the third front knitting position D corresponds to the boundary of the pattern, the color arrangement yarn is laid over the knitting needle group at the first front knitting position C, and further to the knitting needle at the third front knitting position D. When the knitting needles at the third front knitting position D are returned to the first front knitting position C after being also hung, the argyle knitting or the interlace knitting in which the colored yarns are tacked without the need for twisting and intersecting can be performed.

[Effect of device]

 According to the carriage of the present invention, the knitting needle bat from the rear knitting passage can be selected and led out to either the rear knitting position B or the first front knitting position C, and the knitting needle butt from the front knitting passage. Since a front lead-out assisting cam for leading out the first front knitting position C to a second front knitting position C'is provided, in the case of argyle knitting or intarsia knitting, the second front knitting position C is used. If the knitting needles of the second front knitting position C'are not moved even if the knitting needles of the second front knitting position C'are not moved even if the knitting needles of the first front knitting position C are laid over the knitting needle group of the first front knitting position C. Color knitting yarns can be applied to the knitting needles at the front knitting position C ′ by twisting the yarns at adjacent positions so as to intersect with each other to prevent vertical cracking of the pattern. Therefore, as compared with the conventional method in which the knitting needle at the rear knitting position, which is in a state of being largely retracted so as to be sandwiched between the knitting needles at the front knitting position C, is largely pulled out and threaded on the knitting needle, Knitting or intarsia knitting can be performed quickly and efficiently, and can be used not only for hand knitting machines but also for industrial knitting machines.

According to the second aspect, the front lead-out auxiliary cam can be switched, that is, the first position where the knitting needle butt from the front knitting passage can be guided to be guided to the second front knitting position C ′, and the front knitting Since it is possible to switch the knitting needle butt from the passage to the second position where it can be guided to the third front knitting position D further forward from the second front knitting position C ′, the knitting needle butt can be moved to the first front knitting position. The knitting position C and the third front knitting position D can be separately derived. Therefore, with the knitting needle at the third front knitting position D corresponding to the boundary of the pattern, the color arrangement yarn is laid over the knitting needle group at the first front knitting position C, and also to the knitting needle at the third front knitting position D 1. After being hung, if the knitting needle at the third front knitting position D is returned to the first front knitting position C, argyle knitting or intarsia knitting in which tacking is possible without twisting the color arrangement threads Or, there will be more types of knitting methods for intarsia knitting.
