Abstract
A regulated draw unit for drawing sliver running therethrough includes a plurality of roll pairs each defining respective nips through which the sliver consecutively passes in a running direction. A pressure bar which is situated between two adjoining roll pairs has a region for contacting the running sliver. The pressure bar is supported in such a manner that the pressure bar region is spaced from an imaginary straight line extending from the nips of the two adjoining roll pairs, whereby the running sliver is deflected. A measuring device is coupled to the pressure bar for emitting signals representing forces applied to the pressure bar by the running, deflected sliver.
Claims18
A regulated draw unit for drawing sliver running therethrough, comprising
- (a) a plurality of roll pairs each defining respective nips through which the sliver consecutively passes in a running direction;
- said plurality of roll pairs including a first roll pair and a second roll pair adjoining said first roll pair downstream thereof as viewed in said running direction;
- (b) a pressure bar situated between said first and second roll pairs and having a region for contacting the running sliver;
- (c) support means for positioning said pressure bar such that the pressure bar region is spaced from an imaginary straight line extending from the nip of said first roll pair to the nip of said second roll pair for deflecting the running sliver;
- and
- (d) a measuring device coupled to said pressure bar for emitting signals representing forces applied by the running, deflected sliver to said pressure bar.
