Definitions
- the present invention relates to a spinning machine, in particular
- each unit a drafting system for warping a
- False-twisting device consisting of substantially transverse to the thread and these contacting friction surfaces, which is mounted on a spinning machine to obtain a generic spinning machine.
- a spinning machine in which a false twisting device is arranged between a drafting device, on which the sliver is warped and a coil, on which the sliver is wound up.
- the false twist device is according to an embodiment of the local disclosure of a single belt, which is driven by a drive device. Upper and lower run of a belt are driven in opposite directions. The yarn contacts the two Riementrums punctiform (Figure 4), when the belts are arranged directly next to each other.
- the straps are spaced apart and extend substantially vertically one above the other in the opposite direction. The thread wraps in this embodiment, the belt with an angle of about 90 °.
- the false twisting device is formed from a single belt.
- the two Beltrums have the same amount of speed, but they are in the opposite direction. While in these embodiments, the influence of the false twist device by different shapes, speeds or arrangements of the two belt spins of the single belt is very limited, is in the further embodiment of Figure 8 or in the
- Embodiment according to Figure 9 a false twisting device provided with two straps.
- the belts are arranged in a circle, wherein the thread is located between the two belts.
- the object of the present invention is to provide a spinning machine and a false twist device with which a plurality of spinning units of a spinning machine can be operated.
- the false twisting device for the spinning machine should be easy to retrofit to an existing
- the quality of the spun yarn should be very good and interruptions due to a thread break should be only a few.
- the object is also that a yarn with high tensile strength and very low rotation per meter can be spun.
- the object is achieved with a spinning machine according to claim 1 and with a false twist device, which can be arranged on such a spinning machine with the features of the corresponding
- the spinning machine according to the invention has a plurality of juxtaposed spinning units.
- a suitable spinning machine is for example, a ring spinning machine.
- Each spinning unit includes a drafting device for warping a sliver and a spinning device for twisting the warped sliver into a yarn. Between the drafting and the spinning device a false twist device is arranged. In particular, the false twist device is arranged between the nip line on the drafting system exit and the spinning device.
- the false twist device has at least one driven belt, which runs essentially transversely to the thread.
- the thread wraps around two opposite Riementrums z particular, or else s-shaped.
- the two opposing beltrums can come from either a single belt or two separate belts. It is essential that they are driven in the opposite direction and thus can bring a twist in the thread.
- the velocity vectors of the belts, which are friction surfaces for the yarn, are substantially opposed to each other and extend approximately transverse to the longitudinal axis in FIG.
- the belt (s) are preferably made of plastic material. They can have different cross sections.
- the belt rums are in particular z- or s-shaped looped around by the thread, so that the two rotate the thread against each other against oppositely directed components of movement of the belt rums. Due to the fact that the two friction surfaces act on both sides of the thread through the Z or S-shaped loop, the twisting of the thread or of its thread is prevented
- the belt speed is about the same in a preferred embodiment of the invention
- the belt core first contacted by the yarn has a distance of between 20 and 130 mm from the nip line. As it turns out, this distance is important to ensure efficient
- the yarn can In this way with high tensile strength at very low rotation per meter, ie with a very low coefficient of rotation, spun.
- the vertical distance of the underside of the first contacted strand from the bottom of the lower output element of the drafting system is between 0 and 80 mm.
- the wrap angle can be more than 90 °.
- this measure also ensures that the false twisting device and the spinning unit are sufficiently accessible, for example, for maintenance work.
- the horizontal distance of the first contacted Riementrums of the lower output element of the drafting system is between 0 and 80 mm. Again, this range of dimensions is chosen such that the accessibility and the wrap of the belt are obtained in an advantageous manner.
- a distance between 0 and 80 mm has been found to be advantageous, while at a
- the dimensions of the vertical and horizontal distance of the first strand contacted by the lower output element of the drafting system refer in each case to conventional components of the drafting and commercially available lower output elements. It when the two Riementrums are arranged substantially in a horizontal plane is particularly advantageous. As a result, it is achieved in particular in connection with the previously mentioned dimensions that the looping of the belt through the thread is more than 90 ° per belt. The false-twist effect which can thereby be introduced into the thread is thus largely constant. A deviation from the horizontal plane by less than or equal to +/- 10 ° has proved to be advantageous.
- the lower output element of the drafting system is preferably a lower cylinder extending over several drafting systems.
- a relatively inexpensive spinning machine can be built.
- the spinning machine on a drafting with a compacting device is arranged on the pair of output rollers of the drafting system or following the pair of delivery rollers of the drafting system.
- the compacting device has an evacuated sieve strap. Above the sieve strap is arranged a pressure roller which clamps the compacted sliver between the pressure roller and the sieve strap.
- the compacting device may also have an evacuated screen roller. On the screen roller in turn press rollers, which clamp the fiber ribbon and thus form a nip, from which the distance to the first belt rim is measured.
- the mechanical compressor cooperates with the pair of delivery rollers of the drafting system without the need for suction.
- the pair of output rollers forms the said nip line in this case.
- Each of these embodiments of the compacting device has a pressure roller for generating a nip line. This last nip line before leaving the drafting system serves as a measure of the distance to the first belt of the false twisting device.
- the two belts are arranged substantially in a horizontal plane.
- the false-twist effect, which can thereby be introduced into the thread, is thus largely constant.
- a deviation from the horizontal plane by less than or equal to +/- 10 ° has proved to be advantageous.
- the stretching field plane is the plane, which runs through the contact lines of the drafting rollers. With a slope of the stretching field plane at 45 ° to the horizontal, the plane passing through the belts is horizontal, ie horizontal, if the corresponding angle between the belt plane and
- Stretch field level is 45 °.
- the thread is guided in such a way and the false twist device is arranged such that it wraps around at least one of the two belts by more than 90 °, preferably by more than 110 °.
- the second belt lies substantially in the same horizontal plane as the first belt and the yarn is then further withdrawn obliquely downwards from the false twist device. Due to the high wrap around the false twist effect is particularly well introduced into the thread.
- the two belts between the drafting arrangement and the spinning device are arranged such that the first contacted belt is wrapped by the thread more than the subsequently contacted belt, the result is a particularly advantageous and stable spinning process with the generation of a very good thread.
- the belt first contacted by the thread is looped by the thread at an angle between 100 ° and 200 °, preferably between 140 ° and 180 °, and / or the belt subsequently contacted by the thread is at an angle to the thread between 90 ° and 180 °, preferably between 1 10 ° and 140 °
- the invention also relates to a false twisting device with belt and a drive device with the aforementioned features, which is adapted to be grown on a spinning machine to a Spinning machine according to one or more of the preceding claims to create.
