Embodiment Construction

[0022] FIG. 1 schematically shows a combing head KD of a combing machine 1 with a lap roller (WW) on which a filler lap (W) for unwinding is arranged. The fiber raw material is provided to the nipper Z in the form of filler WT, and when the nipper is in the rear closed position, the end of the filler is provided to the circular comb rotatably installed under the nipper for combing.

[0023] In the front position shown in Figure 1, with the nipper Z open, the combed filler ends (also called fiber strands) are supplied to a subsequent pair of detaching rollers 2 for joining to the previously formed web . In the illustrated embodiment, two consecutive teams of separating drafting rollers 2 are shown, in particular the pair of separating rollers directly behind the nipper Z is responsible for the separating and joining operations.

[0024] The former pair of separation rollers 2 are followed by a cotton web guide plate 3, a pair of delivery rollers 4, a funnel 5, calendering roll...

Abstract

The invention relates to a metallic guide device for guiding fibrous material between the lap arbours (WW) and a sliver lay (BA) of a comber (1). To improve the guide characteristics of the fibrous product, at least one of the guide devices (3) is provided with a nanoparticulate surface coating that reduces the adhesion of the fibres.
