- FIG. 1 shows a front view of an upper roller twin with a belt guiding device according to the invention
- FIG. 2 shows a side view cut along the sectional surface H-II of FIG.
- a drafting 1 for warping a staple fiber strand 2 is shown schematically.
- the drafting system 1 consists - as can be seen in Figure 2 - of a plurality of roller pairs 3, 4 and 5, 6, which transport the staple fiber strand 2 in the transport direction A and forgiven to the desired fineness.
- the lower rollers 3 and 5 are driven.
- the upper rollers 4 and 6 are held in a load carrier 7 and are pressed against the lower rollers 3 and 5.
- the pair of rollers 3, 4 are in a conventional manner attackssriemchen 8 and 9 for guiding the staple fiber strand in the drafting zone between the nip 10 of the pair of rollers 3, 4 and the nip 1 1 of the pair of rollers 5, 6 are arranged.
- the top roller 6 is provided with an elastic cover 12 made of a rubber-like material. To protect the elastic cover 12 against excessive wear by the staple fiber strand 2 of the top roller 6 is associated with a strap 13 which wraps around the elastic cover 12. To guide the strap 13 a Riemchen arrangements worn 14 is provided.
- the Riemchen Operations prepared 14 includes a receptacle 15 for the axis 16 of the drafting top roller 6 and a tread 17 for the strap 13.
- the Riemchen Operationss prepared 14 is disposed on the output top roller 6 of the drafting 1, so that the strap 13 forms the nip line 1 1, at the the delay of the fiber structure 2 is completed.
- the wear of the upper roller 6 is particularly strong, since there the Circumferential speed of the rollers 5, 6 is highest.
- drafting units 1 are arranged side by side, as is the case for example with drafting units 1 for ring spinning machines.
- the lower rollers 3 and 5 designed as a machine longitudinal direction continuous sub-cylinder, as shown in Figure 1 can be seen.
- the two drafting top rollers 6 of the adjacent drafting units 1 are arranged freely rotatably on a common axis 16.
- the axle 16 is fixedly received in a holder 18 which is fixed to the load carrier 17 and through which the drafting top rollers 6 are pressed against the lower roller 5.
- the two top rollers 6 and the axle 16 form a so-called top roller twin.
- the elastic covers 12 of the two upper rollers 6 of the Oberwalzenzwillings 19 are each wrapped by a strap 13.
- the receptacle 15 surrounds the holder 18 fork-shaped and is clipped onto the axis 16.
- the Riemchen Installations worn 14 is designed in two parts and a base body 20 and a guide member 21 for each strap 13 contains.
- the main body contains the receptacle 15 for the axis 16 of the Oberwalzenzwillings 19 and is made of a stable material that can absorb the loading forces occurring during operation.
- the main body 20 is preferably made of a fiber-reinforced plastic.
- the guide member 21 includes the tread 17 and two side guides 22, all of which together are referred to as guide surfaces for the strap 13.
- the guide member consists of a sliding plastic, so that the strap 13 on the guide surfaces 17 and 22 finds little resistance.
- Each guide member 21 is attached via receptacles 23 and 24 on the main body 20.
- the guide component 21 can be pushed onto the base body 20 parallel to the axial direction of the drafting unit upper roller 6.
- positioning means 25 in the form of a pin 26 on the guide member 21 and a plurality of grooves 27 on the base body 20 to ensure positioning of the two guide members 21 at predetermined distances from one another.
- Oberwalzenzwillinge 19 different division B are used.
- the pitch B corresponds to the distance of the distorted in adjacent drafting 1 staple fiber assemblies 2.
- the covers 12 of the Oberwalzenzwillings 19 also have a pitch corresponding to the pitch.
- the side guides 22 of the Riemchen operations worn 14 must be coordinated with the division of Oberwalzenzwillings 19 so that the straps 13 run exactly on the covers 12. Due to the adjustability of the guide members 21 and the positioning means 25, the Riemchen Entrys worn 14 invention Oberwalzenzwillingen 19 different pitch B are used without a large adjustment effort is necessary.
- the number and the position of the grooves 27 in the base body 20 is matched to the divisions used in practice B of Oberwalzenzwillinge 19.
- the replacement of a single strap 13 can be simplified.
- the guide member 21 can be pushed down with the strap 13 in the axial direction of the top rollers 6 from the base body 20.
- the strap does not need to be pulled over the side guide 22. It is thus possible to provide relatively high side guides 22, which still ensure a good guidance of the strap 13, when the elastic cover 12 must be reground and thereby reduces its diameter.
- the increased side guides 22 ensure a safe Riemchen Installation even with reduced diameter of the drafting top roller 6 without an additional clamping element must be present.
- a wiping edge 28 for cleaning the apron 13.
- the wiping edge 28 is arranged on the inside of the strap 13 obliquely to Riemchenlaufraum C.
- the wiper edge 28 preferably touches the strap 13 very easily. Due to the inclination of the wiping edge in relation to the Riemchenlaufraum C is possibly stripped on the inside of the strap 13 adhering dirt and conveyed out laterally.
- the strap 13, which wraps around the elastic cover 12 of the drafting top roller 6, can be designed differently.
- the strap 13 may, for example, be designed like a guide strap 8 and have at least on its outer surface a layer of a rubber-like material.
- the strap 13 may also be designed as a so-called Siebriemchen, which consists of an air-permeable fabric. Such Siebriemchen are usually used in the drafting 1 downstream compression equipment for compacting the finished warped staple fiber.
- the scope of the Strap 13 is preferably selected according to the staple length of the fibers present in staple fiber strand 2 and should preferably be greater than the staple length. Such a sized circumference of the strap 13 effectively prevents the formation of unwanted coils on the strap 13, even if the diameter of the drafting top roller 6 is chosen to be relatively small.
- a straight line laid through the center of the axis 16 and the center of the running surface 17 has an angle of approximately 90 ° to the stretching field plane.
- the drafting system 1 is usually angeorndnet in the ring spinning machine so that the stretching field plane is not horizontal.
- the stretching field plane can, for example, extend at an angle of 45 ° to the floor. It may be advantageous that the angle between the stretching field plane and the straight line defined by the center of the axis 16 and the center of the running surface 17 corresponds approximately to the angle between the stretching field plane and the floor.
- the Riemchen extractions worn 14 is approximately horizontal.
- the angle between the stretching field plane and the straight line passing through the center of the axis 16 and the center of the running surface 17 may preferably be about 45 °.
