[0003] It has been found that the flat drive belt has many advantages over the toothed synchronous belt transmission that is still commonly used at present, but because of its relatively high elasticity of the flat belt, it will produce an undesirable shrinkage. This kind of elastic force occurs especially in the case of relatively large changes in speed, so that the speed transmission is wrong, and the belt must be adjusted subsequently for the inevitable expansion and the sliding contraction caused by it.
The toothed belt is relatively easy to operate and not easy to shrink, but its disadvantage is that it is noisy after being polluted and dirty. In addition, the toothed belt transmission will produce the so-called polygon effect (Polygon-Effekt), that is There will be an impact when the top of the tooth enters the tooth groove, and its other disadvantage is that it cannot realize stepless speed regulation

Embodiment Construction
[0034] figure 1It is a transmission arrangement diagram of a drawing frame (Strecke) 1 with a drafting device 2 . Each element of the drawing frame 1 is driven by two motors 3, 40, the first motor 3 is used to drive the elements of the head of the drafting device 2 and the two front drafting rollers, while the second motor 40 is used to drive the rear drafting Elements at the rear of the roller and drafting unit. In order to realize the power transmission between the drive / drive shafts according to the invention, a conveyor belt with at least two longitudinal ribs on a running surface is used.
[0035] the following pair figure 1 The entire transmission configuration diagram of 1 further illustrates: the first motor 3 drives the driving wheel 6 through the main shaft 5, and the periphery of the wheel has a rib-rib-groove structure (see figure 2 ). The wedge belt 7 is tensioned by the driving pulley 6 , which drives the driven pulleys 8 , 14 , 16 , 21 in front of the draft...

Abstract
Textile machine, in particular a textile preparation machine, with a drafting device (2), a plurality of drive discs (6, 8, 12, 14, 16, 17, 19, 21, 23, 25, 26, 19, 42, 44, 45, 51, 53; 70, 75a, 75b) and at least one conveyor belt (7, 18, 24 , 27,43,52; 80; 180; 280), characterized in that: the side of the conveyor belt has at least two longitudinal ribs (81), which are accommodated in at least one conveyor pulley (6,8,12,14,16, 17, 19, 21, 23, 25, 26, 19, 42, 44, 45, 51, 53; 70, 75a, 75b) in complementary longitudinal rib grooves (72) extending on the periphery.
Description
technical field [0001] The invention relates to textile machines, in particular textile preparation machines, with a drafting device, a plurality of pulleys for driving mechanical elements, in particular drafting rollers, and at least one belt which is always wound around at least two pulleys. Background technique [0002] Textile machines, in particular textile preparation machines, have a drafting device, a plurality of pulleys for driving mechanical elements, in particular drafting rollers, and at least one belt which is always wound around at least two pulleys. This kind of textile machinery is well known. The RSB-D35 draw frame from FirmaRieter is equipped with three pairs of rollers. It has a drafting inlet and an increasing peripheral speed to the drafting outlet. The drafting device The bottom roller is to produce a drive that does not shrink, which is essential for driving with a flat pulley, while the top roller is pressed against the bottom roller to clamp the tex...
