Abstract

PURPOSE:To produce a twisted wire at a high speed and to improve productivity by twisting element wires from feed bobbins at a double pitch with a chamber machine, taking up the same on an intermediate bobbin, and subjecting the same again to finish twisting at a double pitch with the chamber machine. CONSTITUTION:Element wires A2 are drawn from feed bobbins 1 and are passed through a feed controller 2 and guide rollers 3, 4 then through capstans 5 and a die 6. The strands past an OT device 7 and capstans 8 are twisted to half the pitch for finish twisting, i.e., a double pitch in a chamber machine 9 and are taken up on an intermediate bobbin 15. The machine 9 is stopped and the strands A2 are cut between the bobbin 15 and the bobbins 1. The end of a false twisted wire A1 is connected to a guide wire A3 conducted from a coiler 21 to a guide roller 16. The coiler 21 and the machine 9 are operated to unwind the wire A1 from the bobbin 15 and while the wire is twisted at the double pitch again in the same way as mentioned above via the chamber machine and the capstans 8, the wire is finished to the finish twist pitch. The twisted wire A is taken up by the coiler 21.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for finishing stranded wire with high twisting speed and high productivity.

In the conventional method, the twisted wire is finished in a puncher machine, and the bobbin in which the finished twisted wire is wound is taken out and replaced. In addition, in order to produce a completed twisted wire within the puncher, devices for processing the straightness, rotation, and wire breakage of the twisted wire must be installed inside the puncher, and as a result, the bobbin has a small diameter. However, in order to make the bobbin larger in diameter, it is possible to increase the size of the guide frame that revolves, but as a result, the guide frame, its support and drive system are The centrifugal force caused severe fatigue, making it unfit for practical use (perhaps it was impossible due to the design), and in the end it was not possible to make the bobbin larger.

The present invention solves all of the problems in the production process at once, by reciprocating the strands between the false twisting device and the intermediate bobbin, and twisting each half-pitch of the MB pitch on the way back to the previous state. , it is characterized in that it is twisted to a predetermined finishing twist level and finished by continuous twisting outside the puncher machine.

That is, the strands (A2) are pulled out from the supply bobbin, passed through the feed controller (2), guide rollers (3) and (4), passed through the capstan (5) to the voice (6), and then subjected to false twisting. A half-pitch twist with a fine pitch is applied by the device (7), and the semi-twisted simulant wire (A,) is passed from the next capstan (8) to the guide roller in the puncher machine (9). 00

The guide frame (b) of fit ('+) also rotates in the same direction and at the same speed.

The roller (17a) of the kink M device a rotates and rotates in the angular direction formed by the roller and its rotation axis to eliminate unstable factors such as kinks in the twisted line.

The twisted wires to which the present invention is applied include wire ropes, steel cords, etc.

Therefore, according to the present invention, there are the following advantages.

Unlike conventional manufacturing methods, the finished MB glands are not produced inside the puncher, so various processing devices can be installed outside the puncher, making use of the available space.
It is possible to increase the diameter of the intermediate bobbin, and it is possible to obtain about 10 times the amount of winding compared to the conventional method.In addition, the false twisting device can twist the half-pitch in the past and the half-pitch in the reversal, making it possible to increase the individual twisting speed. It can be finished by twisting with increased twisting, and its twisting can be produced continuously at high speed compared to conventional methods.
