Description

Thread cleaning device for winding machines. To this day is used to clean the threads, e.g. B. on winding machines, the most diverse Bodies, most brushes or brush-like cloths z, 2 (Fig. R), over which the thread slides o and so from the impurities adhering to the thread is cleaned '. The ones in front of the brushes: 2, to increase the cleaning effect and slats covered with cloth to achieve the winding tension are used for regulation the thread tension can be moved horizontally. Other devices consist of pans with balls or two plates, one rotatable and the other with channels is provided to follow up the impurities. Finally there are already tips. have been used which are at such a 'distance' from the thread running through stand that only impaled its protruding irregularities from the fiber core and be held.

The cleaning of the thread through. these devices correspond to the In no way because of the short duration of use as a result the brushes and cloths no longer serve their purpose after a great deal of wear and tear. can and the grooves and tips are soon filled and then no longer effective. At all The fluff settles into nests of these institutions, which from time to: time be carried away by the thread and form spots of dirt on it.

The object of this invention consists in the use of needle fittings, through which the thread is pulled without with supple Touching the needle base to avoid damaging the needle base. Btim penetration of the thread into the channels between the mutually offset needles he rubs himself constantly against them and loses through their repeated action its nodules and impurities, especially when the population of needles (number Needles on the unit area) increases from the entrance of the thread to the exit. To fill the spaces between the needles with impurities, these contribute to an increase in the Cleaning effect, because then the thread cleans itself in the tangle of fibers, the remains securely retained in the needles and can never be carried away. Will the retaining mass is so dense that threads tear, so you clean the needles a needle plate. Depending on the thread number, there are plates with different wire thicknesses and population to use, Four embodiments of the subject invention are on the accompanying drawing next to the old one that has so far been most used Plastering device laid down: Fig. I shows the well-known arrangement with a putty plate i and cleaning brush -: 2 represent.

Fig. 2 shows the same machine with the straight, equal density Needle fitting according to the invention.

Fig. 3 shows the application of a simple needle field with from Entrance to the exit of the thread increasing population.

Fig. D. illustrates the application of two needle surfaces with different needles.

The figure 5 shows an easily interchangeable for the different thread numbers Sequence of needle areas 8 to 13 in front.

Figure 6 is a version with a slowly rotating needle roller 1.4, which is constantly cleaned by a high-speed roller brush 15.

So-called needle boards can serve as needle surfaces, in which Spar pad 16 (Fig. 4) the pins are hammered in, or so-called scraper fittings, where the straight (Fig. 3) or angularly bent needles (Fig. 5) stuck in a pad made of leather or a scratch cloth 17, or needle rollers 14 (Fig. 6) with very fine needles. The needle pads are either on the needle mount carrier 18 (Fig. 2, 4.) or the prismatic roller body i9 (Fig. 5) nailed or screwed on, or the needle surface base 17 is with brackets -i (Fig. 3) beforehand attached to a board 2-2, which then by means of a screw 2o and wing nut 23 is screwed onto the GestellStlick 24. This ensures easy interchangeability. The thread o is passed over glass rods 25 or in other thread guides, see above that it does not affect the reason for the fitting. The glass rods are in holders 26 guided, which on the frame 18 (Fig. 2, q.) or i9 (Fig. 5) and 22 (Fig. 3) are attached. The prismatic roller body i9 (Fig. 5) is against an unintentional Rotation secured by a known locking device. The roller 14 (Fig. 6), which is studded with straight or knee needles that are either in the thread direction or opposite to her reported, turns very slowly and will! through .the Cleaning roller 15 (Fig. 6) rotating at high speed is constantly cleaned, see above that always clean needles come into work below. The Fadeno goes over three glass rods 25 to keep it away from the roll shell or only over the two outer ones Glass rods 25, if an enamelled roller is used, should not be scored can.
