The invention concerns a cleaning lip for a rotating roll of a textile machine in a rolling mill (1) for processing fibrous materials wherein the cleaning lip (9) is comprised of a combined carrying device and a lip, the length (1) of the lip (11, 23) being limited by a wiping edge (AK, AK.sub.1), and the lip is composed of plastic. On the lip (11, 23) and in proximity to the carrying device, a groove (12, 24) is placed which runs parallel to said wiping edge (AK, AK.sub.1) of the lip. Alternatively, the cleaning lip can be installed for the clearing of wrapping, in that, upon the roll (14) reversing its direction from an original direction, then the wiping edge (AK, AK.sub.1) of the lip (11, 23) swings itself out of its original roll surface contact position. Upon a subsequent change of roll rotation back to the original direction, the wiping edge (AK, AK.sub.1) also swings itself back to its original wiping contact position.

Cleaning lip device for a rotating roll of a textile machine

A fleece guidance system is provided to convey a fiber fleece to the nip of a pair of calendar rollers. The system includes a funnel having a fiber sliver channel defined therethrough which tapers towards an opening adjacent the nip of the calendar rollers. The channel has a longitudinal axis therethrough which is angled relative to a plane through the axes of rotation of the calendar rollers. Oppositely facing guiding segments are configured on the funnel on opposite sides of the opening. The segments have a forward edge which extends into the nip and define lateral guiding surfaces for the fiber sliver exiting from the opening. A plane through the forward edge of the guiding segments and the opening is essentially perpendicular to a plane through the axis of rotation of the calendar rollers.

Fleece guidance system with lateral guidance in the intake area

A process and device are provided to introduce a fiber fleece through the nip of a pair of calendar rollers. Pressurized air is directed to a cylindrical segment of a sliver guiding system down stream from a tapered conical section so that the pressurized air draws the fiber fleece through the sliver guiding system without requiring lateral venting or expansion of the pressurized air. The pressurized air vents from the front end of the cylindrical section adjacent the nip of the pair of calendar rollers.

Air-assisted introduction of fiber sliver before the nip of calendar

A fleece funnel is provided for use in textile drafting equipment to receive a fiber fleece conveyed by a pair of delivery rollers. The fleece funnel includes a long side disposed adjacent to the delivery rollers. A funnel area is defined in the long side for receiving the fiber fleece. The funnel area defines a planar guiding surface in a planar substantially concave impact surface. A funnel opening is defined in the impact surface and a funnel channel is in communication with the funnel opening. A ramp surface is defined on the long side outside of the funnel area. The ramp surface meets the impact surface and defines a common contour line with the impact surface so that air forced out of the fiber fleece balloon formed as the fiber fleece is conveyed into the funnel opening is drawn away from the funnel area towards the ramp surface unimpeded by planar components of the fleece funnel.

Textile machine fleece funnel

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.

Swiveling fleece funnel for fiber sliver guidance without guiding

A fiber sliver guidance system for a textile machine drafting equipment is provided and includes a first nozzle section disposed relative to the delivery rollers to receive a fiber fleece therefrom and form the fiber fleece into a fiber sliver. A second nozzle section is connected to the first nozzle section to receive the fiber sliver therefrom. The second nozzle section includes an essentially cylindrical sliver channel disposed to guide the sliver to the nip of the calender rollers. The sliver channel of the second nozzle section includes a guiding section defined by spaced apart end segments which extend on opposite sides of an alongside the calender rollers past the nip. The side signals cooperate with the calender rollers to define a limited air loss channel for the fiber sliver directly to the nip.
