Abstract
A fiber sliver guidance system is provided for 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. The guidance system is disposed between the delivery rollers and the calendar device and includes a plurality of nozzle inserts which define a fiber sliver channel between the delivery rollers and the calendar device. The fiber sliver channel has an axis defined by two axial segments which can be angled relative to each other. At least one of the nozzle inserts can be articulated relative to the other nozzle inserts about a swivel axis. The articulatable nozzle swivels automatically from an operating position to a closed position upon a back-up of fiber fleece in the fiber sliver channel.
