Definitions
- the invention relates to a drafting system for a spinning machine, with a pneumatic compression device, which a means of transport Perforations and a suction device connected to it via a suction opening has, which on the side facing away from a fiber structure Transport means between at least one output roller and a delivery device extends, in the effective area of the suction opening, the suction device opposite, a shielding element is arranged.
- Such a construction already belongs to the prior art (DE 198 15 325 A1), in which between a drafting system and a rotation and winding device arranged a perforated compression element is over which there is a screen.
- a perforated compression element is over which there is a screen.
- the output bottom roller which is designed as a perforated suction roller, contains the compression element.
- the aforementioned screen has redirecting functions and should influence the air flow in such a way that it flows from both sides to the Fiber association acts and thereby improves the yarn quality.
- These umbrellas require separate holding elements that the insertion of a sliver in hinder the fiber bundling zone.
- the present invention is based on the object pneumatic compression drafting system of the type mentioned To facilitate insertion of the fiber bands in the fiber bundling zone.
- the shielding element is immediately attached the suction device is arranged, the shielding element one after limited open area, into which a fiber structure can be inserted from the outside is.
- the shielding element is designed as a resilient tongue and is provided at the end with an end profile that the open Covering the outside area.
- the shielding elements can be pressed back and the Fiber dressing introduced into the open area or an old strap removed and a new one can be used.
- the spring force of the shielding elements can be dimensioned so that it is solely due to the spinning existing thread tension opened and then as a result of the spring action to be closed automatically.
- Figure 1 is a drafting system 1 for a spinning machine for bundling a the drafting to be warped fiber structure 2 shown.
- the drafting system 1 has three pairs of rollers 5, 6 and 10. In the area between second roller pair 6 and the output roller pair 10 finds the main delay of the fiber structure 2 instead.
- a pneumatic compaction device connects to the output roller pair 10 30 of a delivery device 35 in the form of another Subordinate pair of rollers.
- the area between the pair of exit rollers 10 and the delivery device 35 represents a so-called fiber bundling zone.
- the one leaving the output roller pair 10 of the drafting system 1 becomes Fiber dressing 2 over the corresponding length one transverse to the direction of transport directional suction air flow exposed. This can be done with a Perforation track 45 provided means of transport 15, for example a strap, Find application.
- the compression device 30 further comprises a suction opening 22 and an associated suction device 25, which is on the fiber structure 2 facing away from the transport means 15 between the pair of output rollers 10 and the delivery device 35 extends.
- This suction device 25 has a suction shoe 26, via which the means of transport, namely the perforated strap 15 is guided.
- the suction shoe 26 stands with a suction line 27 in connection to a vacuum source, not shown connected.
- Fig. 5 shows the shielding element 40 in the closed position, i. H. the fiber structure 2 is located in an outwardly openable area 42 of the shielding element 40.
- the shielding element 40 consists of a resilient Tongue 47, which has an end profile 48 at the end, which is the open one Area 42 covers the outside.
- the suction air flow becomes more advantageous Optimized way, while at the same time the energy requirement for generation of the required negative pressure drops.
- the Operating the drafting system especially threading when piecing, when changing straps and performing cleaning work not disabled.
- the effort for setting and Adjustment of the shielding elements prevented.
