Definitions
- DE 43 23 472 C2 discloses a method for bundling or compacting (compacting) of a finished in a Doppelriemchen drafting distorted fiber structure, which is summarized following the delay in a fiber bundling zone and twisted together to form a thread.
- the fiber structure is supported on one side during the summary by means of a suction air flow by a transport in the form of an endless, flexible, perforated belt.
- the device for carrying out this method has an adjustable support, by means of which the position of the perforated belt is adjustable to Nipp of the output roller pair of the drafting system.
- the effect is achieved that the distorted and compacted, but not yet solidified by twisting fiber structure does not fall off the perforated belt and causes a yarn breakage, when the induced draft breaks through the strap. This would be the case when stopping the machine or in case of errors in the maintenance of the induced draft. Such yarn breaks must be corrected by hand. In particular, if they were to occur frequently, this would pose an unacceptable workload for the operator.
- Another advantageous effect of the support is that it throttles the access of air by covering the perforation track and thus reduces the energy consumption in the transport zone. Since it has been shown that the compression effect takes place substantially only in a compression zone immediately after the exit of the fiber structure from the delivery roller pair and before it enters between perforated belt and cover, the compression effect is not affected by the cover or even disturbed.
- the perforated strap In order to ensure a secure concern of the perforated strap to the suction shoe, it has proved to be useful, the perforated strap not straight, but light arched lead. It makes sense to adapt the contour of the support device to this leadership of the strap.
- the object of the invention was to provide a purposeful, easily adaptable and advantageous in many respects embodiment. It solves this problem by the features mentioned in the main claim.
- Abstützklipse In order not to disturb or adversely affect the compaction process, the support effect of Abstitzklipse can be limited to the perforated strap on the viewed in the direction of passage rear portion of the upper surfaces of the Abstützklipse or laterally of the perforation track arranged skids.
- Fig. 1 illustrates the cross section through the compression region of a drafting system
- Fig. 2 and 3 show the top view of rails with two different
- the area between the output roller pair 1/2 and the roller pair 3/4 of the compression unit consists of a compression zone 18 between the discharge line of the fiber structure of the output lower roller 1 and the belt 5 before it reaches the upper surface 15 of a Abstützklipses 13. Only in this compression zone is a compression of the fiber structure.
- This compression zone 18 is followed by a transport zone 19, in which the compacted fiber structure is fed to the roller pair 3/4 of the compacting unit.
- This pair of rollers constitutes a rotation stop for the propagation of the rotation imparted to the fiber structure by the downstream spindle into the transport zone 19.
- the course of the fiber structure is indicated by a dot-dash line 20.
- a rectangular cross-section rail 12 is arranged, which extends between two punches of the drafting system. Your height position for drafting plane can be changed by not reproduced here adjustment means such as screws or insertable spacers. On this rail support braces 13 can be pushed and detected from below by means of set screws 14. It is assigned to each workstation of the drafting a Abstützklips.
- the support clips 13 are made of plastic or metal, in particular aluminum.
- the upper surfaces 15 of the Abstützklipse 13 may be flat. Since the strap 5 under the arched suction shoe 9 is usually not straight out, also the upper surfaces 15 of the support ellipse 13 are correspondingly bulge. This curvature is advantageously adapted in each case the guide surface of the strap 5 under the suction shoe. However, other shapes for the upper surfaces 15 of the Abstützklipse 13 advantageous be. For example, a shape can be recommended, in which the support of the
- Riemchens 5 is concentrated on the rear region in the fiber bundling zone.
- the suction shoe 9 can laterally of the perforated belt 5 support skids 16, with which it is supported on the upper surface 15 of its associated Abstützklipses 13. These skids also serve for lateral guidance of the strap. This will be the light one
- the support skids 16 have the effect of preventing the lateral, axial access of air to the perforation track. This further reduces the air consumption of the device and advantageously concentrates the admission of air on the radial or tangential flow in the direction of the fiber run through the zone following the compression zone. It is understood that such skids can be arranged instead of the suction shoe 9 on the upper surface 15 of a Abstützklipses 13.
- the strap 5 is supported on these skids 17. Also by such skids the access of air to the perforation track is prevented in the axial direction.
- the area between the pair of output rollers 1/2 and the pair of rollers 3/4 of the compression unit consists of a compression zone 18 between the discharge line of the fiber structure of the output lower roller 1 and the
- This compression zone 18 Only in this compression zone is a compression of the fiber structure.
- This compression zone 18 is followed by a transport zone 19, in which the compacted fiber structure is fed to the roller pair 3/4 of the compacting unit.
- Roller pair represents a rotation stop for the propagation of the fiber strand through the subordinate spindle issued rotation in the transport zone 19.
