Definitions
- the invention relates to a roller for apron drafting systems from Spinning machines with a recessed towards the edge areas Middle zone.
- Such rollers for apron drafting systems are so-called channel rollers, in different Embodiments known.
- the edge areas transmit the high pressure on the upper and lower straps to their safe transport and precise running. May in the central zone only very little pressure on the straps on the fibers be exercised so that fiber transport is guaranteed on the one hand, on the other hand, fiber distortion is not hindered becomes.
- a distinction is made between duct rollers with an in a rubber cover with a certain depth, Duct rollers with elastic duct lining and duct rollers with inelastic edges and therefore unchangeable channel depth.
- the invention has for its object a roller for apron drafting systems to improve that on the one hand non-slip and exact belt run is guaranteed and that the very low contact pressure in the middle area automatically adapts to the respective yarn count.
- the invention solves this problem by a roller for Strappy drafting systems of spinning machines with one opposite the marginal areas deepened central zone, in the area of A radially movable sleeve is arranged in the central zone.
- Now can yarn of different fineness without any change with high quality in the drawing process.
- the radially movable sleeve provides for light pressure of the straps on the inserted fibers. This ensures thread transport without being easy To hamper stretching. Because the sleeve from the strappy is wrapped at an angle of more than 180 °, the Upper apron center of the upper apron of the lifting movement towards the sleeve.
- the thickness of the fiber bundle affects thus the pretension of the strappy.
- a too high pressure of the Fiber bundle is avoided by making the sleeve radial is movable and through the straps in the channel area Follow the apron pretension by the apron leader is pulled into the partial gap of the strappy at the front. Thereby the straps lay down with less, but for transport sufficient force on the fiber bundle.
- the elasticity of the Strappy is therefore used to apply a light pressure to generate, which the sleeve passes on the fiber bundle.
- the Contact pressure causes fiber transport without Thread breaks are guaranteed and on the other hand in the fiber bundle only such distortion forces arise that the yarn stretch does not to reduce.
- the outer diameter of the sleeve can be the same as that Diameter of the two edge areas or slightly different be of it.
- the sleeve can be between have an axial play in the two edge regions.
- the roller can be mirrored by two Parts consisting of an edge area and an axis extension, be formed, the axial processes touching and limit the radial deflection of the sleeve.
- the sleeve can be made of a high density material or be made with a thicker wall.
- Fig. 1 shows an upper roller with two channel rollers 10, wherein each roller 10 of two mirror-image identical parts 11 and 12 is formed.
- the two mirror-inverted parts 11 and 12 consist of an edge area 13 and 14 and an axis extension 15 and 16.
- the two axis extensions 15 and 16 collide in the middle of the roller 10 and form the channel of the roller 10.
- the two axis extensions 15 and 16 are surrounded by a sleeve 17.
- the sleeve 17 has one optimal contact pressure of a drive belt shown in FIG. 2 20 a radial clearance 18.
- the fiber 17 also has an axial sleeve Game 19 on.
- Fig. 2 shows the roller 10, which among other things, the axis extension 15 has.
- the axis extension 15 is from the sleeve 17th surround.
- a strap 20 wraps around the roller 10 together with the sleeve 17 and is also guided by a strap guide 21.
- the Due to the strappy tension, sleeve 17 attaches strappy 20 very little pressure on the fiber bundle, taking it by a radial play 18 with respect to the axis extensions 15 and 16 automatically adjust to the thickness of the fiber bundle can by making an evasive movement to the strap guide 21 there. In this position, the sleeve 17 runs with the Straps 20 and parts 11 and 12 wear-free.
