Embodiment Construction

[0029] figure 1 , 2 Only the region of a device 1 for bundling a drawn but untwisted fiber sliver 2 of a spinning machine, in particular a ring spinning machine, is shown. The device 1 is immediately downstream of the drafting mechanism 3, only the output roller pair 4 of the drafting mechanism is shown, a pair of aprons with a lower apron 6 and an upper apron 7 arranged upstream of the output roller 4 Rolla. The output roller pair 4 comprises a driven output bottom roller 8 and an output pressure roller 9 elastically pressed there. The delivery roller pair 4 defines a nip line 10 forming the end of the drafting zone of the drafting mechanism 3 .

[0030] In the drafting unit 3 a fiber strand or roving 11 is drawn in the conveying direction A to the desired fineness in a known manner. The drawing process ends at the output nip line 10, and from this point on there is a drawn but still untwisted fiber sliver 2. In order to reduce the known unfavorable spinning triangle, th...

Abstract

The transport belt is made of an air permeable cloth material containing synthetic filament in the fiber strand (2) guidance portion and a static reduction substance.

Description

[0001] This application is a divisional application of the invention patent application whose original application number is 200410047519.1, the title of the invention is "conveyor belt for conveying fiber sliver", and the application date is May 21, 2004. technical field [0002] The invention relates to a conveyor belt in the form of an air-permeable monofilament fabric for conveying a fiber sliver away from a drafting mechanism through a bundling zone, in which said conveyor belt slides through a suction slot, and Air flow is drawn through the conveyor belt. Background technique [0003] When the drawn fiber sliver is spun and twisted in the spinning machine just behind the pair of delivery rollers of the drafting mechanism, the so-called spinning triangle appears on the nip line of the pair of delivery rollers. This is because a drawn fiber sliver of a certain width leaves the drafting mechanism and is twisted into a thinner thread. The spinning triangle includes edge f...
