Definitions
- the invention relates to a double apron drafting system for spinning machines, with one Delivery nip line having delivery rollers, with an upstream one, a fiber structure in leading the area of the delivery clamping line and forming a gusset pair of straps and with devices for keeping away from those rotating with the pair of delivery rollers Air currents from the area of the delivery clamp line.
- DE 30 39 149 C2 proposed that Exit area of the strappy pair opposite the delivery nip line of the delivery roller pair in to move a direction transverse to the path of the fiber structure. The idea was that by moving the fiber run can avoid the air flows mentioned in order then in an area near the surface of the closest roller of the pair of delivery rollers to reach the delivery clamp line.
- this measure was a failure prejudiced, because of course it could not be prevented that with the pair of delivery rollers circulating air flows at the delivery terminal line are interrupted and on everyone Lead to air turbulence.
- JP (B2) 62-15649 attempts have been made to pair the delivery rollers in the area of the gusset to be encased between the pair of straps and the delivery clamping line.
- thin Metal plates provided that had a contour adapted to the delivery rollers and in the area of the delivery clamping line on the rollers. These plates had a slight one Distance through which the fiber structure was passed.
- the disadvantage of this measure was only that these shields are in the gusset area between the strappy pair and the Delivery clamp line were so that the strappy pair at a clear distance in front of the Delivery clamp line had to end, resulting in an increased unguided length of the fibers of the Fiber association led.
- the invention is based on the object in a double apron drafting system at the beginning mentioned type the undesirable air flows as effectively as possible from the delivery terminal line keep away without bringing the strappy pair as close as possible to the To hinder the pair of delivery rollers.
- the object is achieved in that the devices for keeping away from the Supply roller pair of circulating air flows outside of the delivery nip line with the Strappy pair formed gusset, but in the immediate vicinity of the delivery roller pair and Strappy pair are arranged.
- the means relative to the scope of the assigned Roll have a preferably adjustable distance.
- These funds can, for example contain a covering with a sealing gap, which if possible down to about 0.1 mm should be downsized. With increasing reduction of the radial sealing gap decrease the unwanted air currents.
- the means cover the scope of the touch the assigned roller.
- this gives the greatest effect because it means that Boundary layer of air currents is destroyed with certainty.
- This can be advantageous a lip touching the associated roller or spring-loaded bar.
- Such Agents can optionally also contain a slowly rotating role, which on their Perimeter is provided with pockets, for example, with which any waste fibers are collected become. Due to the slow rotation of the roll, the bags can be opened from time to time empty or, if necessary, vacuum continuously.
- the funds can be one Included brush, which is attached to the associated roller. Such a touching fine brush is Especially favorable for the top roller of the pair of delivery rollers.
- the boundary layer of the unwanted airflow can be most effectively interrupted, however, just this measure, in turn, has the disadvantage that it may not also encircle fibers be clamped as desired.
- the said means contain suction.
- Suction which may already be used to destroy the boundary layer of the rotating Air flows could be used can be advantageous in all of the variants mentioned be used.
- the connection of the peripheral surfaces of the pair of delivery rollers touching device with an associated suction has proven to be particularly effective proved. If necessary, it can be provided that the suction is closed by a suction roller realize.
- the double apron drafting system for spinning machines shown in FIG. 1 is a three-cylinder drafting system formed and contains a pair of feed rollers 1,2, a pair of apron rollers 3.4 and a pair of delivery rollers 5.6.
- the rollers 1, 3 and 5 are driven lower rollers, in the case of rollers 2, 4 and 6 around the associated resilient ones Printing rollers.
- the strappy roller pair 3.4 is wrapped by a pair of straps 7.8, whereby the strap 7 is a bottom strap and the strap 8 is a top strap.
- At 9 is one Deflection guide for the bottom strap 7, with 10 a deflection guide for the top strap 8 designated.
- the delivery roller pair 5,6 defines a delivery nip line 11 on which the delay of the Dotted line, to be drawn fiber structure 12 is finished.
- the fiber structure 12 is fed to the double apron drafting system in accordance with the feed direction A and after the delivery clamping line 11 in delivery direction B forwarded to a swirl member, not shown.
- FIG. 3 is a non-contact device to prevent the Air flows are provided at least on the lower roller 5, these devices being one adjustable lip 23 included, which in turn is connected to a suitable suction 24.
- the distance between the lip 23 and the circumference 21 can be adjusted such that the gap is significantly smaller than 0.2 mm.
- FIG. 5 is a slow counter to the direction of movement of the bottom strap 7 and Lower roller 5 revolving roller 28 is provided, which is provided with pockets 29 on its circumference, with which waste fibers can be removed if necessary.
- the roll 28, the circumference 21 touches the lower roller 5, can be connected to a suction in a manner not shown his.
