Swiveling fleece funnel for fiber sliver guidance without guiding channel and process for the operation of same

A swivelling fleece nozzle for insertion into a fiber sliver guidance system having two axial segments for a textile machine drafting equipment wherein a fiber sliver is drafted by pairs of drafting rollers and conveyed by a pair of delivery rollers to a calendar device, said fleece nozzle 15 adapted to be movable in said sliver guidance system relative to one axial segment from an operating position wherein fiber fleece is received from said drafting and delivery rollers and conveyed through a fiber sliver channel to a closed position wherein said fiber fleece is deflected from said fiber sliver channel, said fleece nozzle further comprising a funnel section for receiving and rolling said fiber fleece in said operating position and a ramp section for deflecting said fiber fleece from an operating conveying path in said closed position.

A process for guiding fiber fleece from drafting and delivery rollers of textile drafting equipment through a fiber sliver channel to a calendar device wherein the fiber fleece is automatically deflected from the drafting equipment upon a back up of the fiber fleece in the fiber sliver channel, said process comprising conveying the fiber fleece through a fiber sliver channel formed of at least two axial air tight interconnected segments wherein, upon a back up of fiber fleece in said fiber sliver channel, at least one of the axial segments automatically swivels from an operating position wherein fiber fleece is conveyed through said fiber sliver channel to a closed position wherein the fiber fleece is deflected away from the drafting equipment.
