Claims (3)

1 2 is a bridge over which one of the patent claims has a significant effect: influencing the vibration behavior of the spindles by the vibrations of the pressure rollers and 1. Two-for-one twisting machine. returns occurs in which the spindle whorl on one side of the spindle 5 by US-PS 3946 545 is already one bank protruding freely and known by a parallel to the twisting machine, in which the spindle bank under Machine longitudinal axis extending through the interposition of damping material ais of pressure rollers against the spindle whorl of the longitudinal beams of the machine frame independent construction Tangential belts can be driven, part of which is attached to the machine frame This printing however, there are no references to the arrangement of the devices for vibration-related io writing Decoupling of the pressure rollers and the spindles of the pressure rollers and decoupling measures between are provided, can be seen from the spindles and the pressure rollers. and with the spindle bank in the machine length. Axis vertical machine stands is attached. Preferred developments of the invention result characterized in that the device is defined in the subclaims. device for the vibration-related decoupling of the following are exemplary embodiments of the invention Pressure rollers (33) and the spindles (6) are described using the drawing. It shows the supporting structure extending parallel to the spindle bench (2) ken (26) is provided on which the pressure rollers Fig. 1 is a perspective partial view of an inven- are attached and the two-for-one twisting machine with horizontal independent component on machine frames (1) zontal alignment of the spindle axes; Fig. 2 is a perspective partial view of an invented 2. Two-for-one twisting machine according to claim 1, the two-for-one twisting machine according to the invention with vertikada through characterized in that the support beam (26) at ler alignment of the spindle axes; the machine stands (1) in vibration dampers- 25 F i g. 3 a cross section through a spindle bench, is suspended from the elements According to FIG. 1 is between the machine stands 1 3. Two-for-one twisting machine according to claim 1 of a Feldts of the two-for-one twisting machine in each case or 2, characterized in that mounted on a single spindle bench 2 The spindle bench 2 assigns on the support beam (26) the several tangential straps on both sides of the side flanks 3. Each spindle bank 2 mentrumen assigned pressure rollers (33) is 30 - as Fig.3 shows in detail - from two im are arranged. Cross-section of U-shaped folded plates 2.1 and 2.2 manufactured which are screwed together with the flanks 25. In the middle plane of the spindle bench 2 a middle partition 4.5 is mounted on the spindle 35 bank 2, the bearing housing 8 for the spindles 6 are stationary stored The spindles 6 consist in particular of spindle whorl 7, balloon limiter 9, protective pot 10, The invention relates to a two-for-one twisted machine bobbin 11 and spindle top part 12. The spindle layers according to the preamble of claim! .. tion is constructed so that the spindle whorl 7 on the In known two-for-one twisting machines this 40 is on one side of the spindle bank and the spindles themselves Art is protruding from the other side of the spindle bank 2 as a device for vibration control. Of the coupling of the pressure rollers and the spindles an ela drive of the spindle whorl 7 of each spindle bank 2 Tical fastening of the spindle and roller bearings is done in advance by a tangential belt 23, 24, which see, which is sometimes also designed in such a way that it rests tangentially against the spindle whorls 7. Everyone occurring vibrations are dampened. With all 45 tangential belts, guide and tensioning elements Devices of the type mentioned, the storage elements are guided and tensioned and by pressure rollers Pressed against the spindle whorl 7 relatively close to one another on the same counter 33. For storage Adjusting elements, usually the spindle bench, attached. the pressure rollers 33 is used by the support beam 26. The Because the decoupling facilities - damping girder 26 is also between the two, one or non-damping elastic elements - their 50 machine frames delimiting the machine field 1 to decouple only imperfectly and not superimposed, regardless of the spindle bank 2 with meet the entire frequency range to the same extent, by means of an independent connector in the form of the However, the vibration behavior of the spindles of the fastening angle iron 32 is reduced. due to the vibrations of the pressure rollers, bank 2 and spindle bearings on the one hand as well as the belt and vice versa. 55 on the other hand, vibration and noise It has been shown that a considerable amount of noise is isolated from each other, source lies. For each machine side of the two-for-one twisting machine The object of the invention is to provide a double machine with horizontally aligned spindles peld wire twisting machine of the type mentioned so a spindle bank with two rows of spindles, the to train that the noise is reduced. 60 are horizontally aligned. The spindles This task will be carried out in the characteristic of each side of the machine by one in each case Part of claim 1 specified measures solved. Tangentailriemcn 23, 24 driven. The spindle banks Through the support beam, one of the spindle bench are arranged so that they are together with the cover is an independent component, the Andrückrollcn with blades 29 and 30 form a box-shaped housing, in their bearings from the spindles with their bearings b5 which the spindle whorl 7 protrude and in which gen mechanically separated, it has been shown that the tangential belts 23, 24 are guided. In the box mechanical connection between the support beams are also the support beams 26, which and the spindle bench on the machine stands none for holding the pressure rollers for the tangential
