Is inserted, so that the size of the draw false twisting machine can be reduced, and the workability such as threading can be improved.

Furthermore, when two drawn and false twisted yarns 3 are to be combined, they are guided by a pair of guide grooves 27 a of a yarn guide 27 disposed in one heating space 26. Since the two yarns 3 can be combined, the yarn is not excessively bent, and therefore, the quality of the combined yarn is improved.

In the embodiment described above, the heating space 26
An example is shown in which a pair of, ie, two, guide grooves 27a are formed in the yarn guide 27 disposed therein. However, three or more guide grooves 27a are formed, and one heating space 26 is formed.
It can be configured to insert three or more yarns 3. In such a case, the number of the guide grooves 28f 'arranged in parallel with the yarn guide block 28f is also three or more corresponding to the above-described guide grooves 27a.

[0030]

Since the present invention is configured as described above, the following effects can be obtained.

Since a plurality of yarns can be inserted into one heating space, the processing efficiency of the yarns in the heating space is improved.

Since the cross section perpendicular to the length direction of the heating space is tapered toward the yarn insertion port of the heating space, the yarn insertion port is formed narrow. Heat radiation from the yarn insertion port can be effectively suppressed.

Since a plurality of yarns are inserted into one heating space, the size of the drawing false twisting machine can be reduced, and the workability of threading and the like can be improved.

When a plurality of drawn and false-twisted yarns are to be combined, a plurality of yarns guided by a plurality of guide grooves of a yarn guide disposed in one heating space are combined. So that the yarn is not excessively bent, thus improving the quality of the plied yarn.

A thread guide member having a thread guide block having a plurality of guide grooves is provided on the thread introduction / lead-out side so as to correspond to the thread guide having a plurality of guide grooves disposed in the heating space. Therefore, it becomes easy to hook the yarn on the yarn guide disposed in the heating space.
