Problems solved by technology

For this reason, the fiber slivers fed by the terry straightener can largely be prevented from entering the impurity collection tank when the casing swings, but when the casing swings, the distance from the terry straightener to the fiber sliver collector The spacing changes automatically, resulting in a loose state of the fiber strip

Embodiment Construction

[0013] FIG. 1 only shows the air spinning box 1 in the region of a feed device for feeding a fiber sliver 2 to a feed roller 3 . The components of the device are shown enlarged in the figure 2 middle.

[0014] The air spinning box 1 comprises a fixedly mounted part 4 and a casing 5 which can be swung away from the part 4, the swivel position of which is indicated by dashed lines and marked with the reference numeral 5'. Here, the pivot axis 6 belongs to the fixedly arranged component.

[0015] In addition, the fixed part 4 contains a rotor housing 7 under vacuum, a rotor 8 rotating in the housing, and a rotatably mounted driven rotor shaft 9 as well as a rotor shaft 6 mounted on the swivel axis. Impurity collection tank 10 below and parallel thereto. In a known manner, the groove is used to collect the impurities separated in the region of an opening roller not shown in the figure during the spinning process, and these impurities must then be removed continuously or periodi...

Abstract

A feeding device for feeding a fiber strip to a feeding roller of airflow spinning box comprises a fixed cover member and a swinging cover capable of swinging around a swinging axis. Said swinging cover supports a feeding roller and a fabric strip condenser adjacent to upstream of the feeding roller, a loop straightening mechanism is mounted and a fabric strip support saddle is connected to the side of the condenser. A fixedly installed impurity collecting vat locates below the swinging axis, and then parallel to each other. Therefore, the fiber strip still keeps its tensile force even when the cover swings and will not enter into the impurity collecting vat, the fiber strip condenser and loop straightening mechanism keep the relative movement all the time, with a mutual distance therebetween. For example, the loop straightening mechanism can swing surrounding the articulations of the fiber strip condenser.

Description

technical field [0001] The invention relates to a feeding device for feeding a sliver to a feed roller of an air spinning box, which is equipped with a sliver collector arranged immediately upstream of the feed roller, upstream of the collector A terry straightener and subsequently connected sliver support are placed, and a pivotable casing supporting the feed roller, sliver collector, sliver support and terry straightener is provided and an impurity collection tank located below the swing shaft and fixedly arranged in parallel. Background technique [0002] The prior art of such a device was reported in the December 2000 "Süssen Technical Information" publication SKT.0007 ND. A diagram of the device is shown on page 2 of this publication at right. This known device combines a loop straightener, a sliver holder and a sliver collector into a compact one-piece assembly. This can lead to the disadvantage of certain fiber sliver materials, that is, the fiber sliver enters the...
