Description

[Detailed description of the invention]

The present invention essentially consists of one revolution C2 (61 twists) which allows continuous application of paraffin to both yarns during normal yarn twisting before the double strand is unwound. In the known technology, the device for supplying paraffin to a twisting machine (Guburu Twister) in which the twisting machine is
It is known that the application of paraffin to the laid threads can be carried out after the twisting process and that extra winding operations are carried out for this purpose. The prior art also describes the use of a paraffin applicator which is mounted directly on the twisting machine and consists of a head holding a paraffin disk and a head in an opposite position, these rads cooperating with each other. It is known as described in DE 2316452, CH 378 750 and US Pat. No. 3,358,641. This paraffin disk can be placed axially and against a suitable device for pressing the thread, in particular the aforementioned Swiss Patent No. 378,750 and US Pat.
No. 8,641, the above-mentioned known apparatus for applying wax paraffin, which is pressed by the holding head against a suitable opposing surface device constructed at one of the above-mentioned opposing positions, is expensive. The handling of paraffin disks is not easy because of the structural complexity and the specific motion exerted on the disk by these devices t#'i, said heads and said heads in opposing positions. The object of the present invention is to provide an improvement for applying paraffin in a Dubhachi twister, which makes it possible to effectively work on the double strand yarn before it is wound onto the spool. It is in the implementation of the device. Another object of the invention is to enable simple and fast operations when installing and removing paraffin discs and when inserting double strands in the device in question for applying paraffin. Yet another object of the invention is to make it possible to adjust the fine directional positioning of said paraffin discs using an adjustable suppression device so that the application of paraffin to the double strand is constant. . Furthermore, the suppression device locks very close to the device and can be easily removed laterally, thereby effectively reducing the overall dimensions of the paraffin application device. Allows you to do a little. The paraffin applicator according to the invention also makes it possible to easily stop processing the thread. Historically, the equipment in question for applying paraffin has been constructed in such a way that it does not allow I4 formation of impurities inside or outside itself. In particular, said paraffin application device constitutes a fixed support structure which is locked to a support bar creating a locking surface 55 for other devices applying paraffin which are also included in the same twisting machine. . Said structure rotatably holds a spindle and a drum having a seat 61 for supporting a paraffin disk, such that the spindle and drum rotate and the disks rest on their seats 61 on the drum. The paraffin disk is reciprocally engaged with a paraffin disk rotated by a spindle which is pressed against the structure so that the papermaking drum also finely adjusts the position of the paraffin disk. can be slid concentrically on the part. Said rotating spindles are rotated by means of a belt and a device representing a bree or gearing and obtain their movement in a known manner from a common drive shaft arranged longitudinally along the twisting machine. Thus, the six-strand device configured for applying paraffin is arranged substantially upstream from the winding device configured in the twisting head with which said device cooperates and processes the already twisted yarn. The invention is therefore implemented in a paraffin device located upstream from a winding device for the head of a double twister, supporting paraffin disks, all supported by a fixed support structure. a support device for;
This support device includes a device for abutting against the end of the paraffin disk, a spring device for pressing the support device against the abutment device, and a shaft device for rotating the paraffin disk. dub l including
