Embodiment Construction

[0047] figure 1 A sectional view of a fleece funnel 1 with an inlet side 2 formed elongately in the x-direction is shown. The fibrous fleece, not shown here, enters the fleece hopper 1 via the inlet side 2 . Spaced apart from the input side 2 in the z-direction is an output side 3 . An outlet opening 4 is formed in the outlet side 3 , through which the fibrous fleece compressed into a fiber strip emerges from the fleece hopper 1 . The outlet opening 4 is preferably configured with a circular cross section. In the present exemplary embodiment, two guide surfaces 5 a , 5 b are arranged between the inlet side 2 and the outlet side 3 , which form the actual funnel function of the nonwoven funnel 1 . The fibrous fleece stretched in the x-direction enters the fleece hopper 1 via the input side 2 . At least the edge region of the fibrous nonwoven hits the guide surfaces 5 a , 5 b and is diverted from there in the direction of the output opening 4 , where it leaves the nonwoven fu...

Abstract

The invention relates to a non-woven funnel for compressing a fiber non-woven, in particular on a draw frame, carding machine, or combining machine, comprising an inlet side (2), which is elongate inthe x direction and at which the spread fiber non-woven formed of individual fibers enters the non-woven funnel (1), an outlet side (3), which is spaced apart from the inlet side (2) in the z direction and at which the fiber non-woven exits the non-woven funnel (1) as a sliver, an outlet opening (4), which is arranged on the outlet side (3), and at least one guiding surface (5a, 5b) for the fibernon-woven arranged between the inlet side (2) and the outlet side (3), in order to guide the fiber non-woven flowing into the non-woven funnel (1) toward the outlet opening (4). According to the invention, at least one guiding element (6, 12) is arranged in a region between the inlet side (2) and the outlet opening (4), which at least one guiding element limits a motion component of the fiber non-woven in the x direction and/or a motion component of the fiber non-woven in the y direction, wherein the guiding element (6, 12) is arranged in such a way that the guiding element prevents the collision of the fibers against each other at least in the x direction after the fiber non-woven has been redirected toward the outlet opening (4) by means of the guiding surfaces (5a, 5b).

Description

technical field [0001] The invention relates to a A nonwoven fabric funnel for compressing a fibrous nonwoven fabric. The fleece funnel has an inlet side that is elongated in the x-direction, at which the stretched fibrous fleece enters the fleece funnel. Spaced apart from the input side in the z-direction is an output side at which the fibrous nonwoven exits the nonwoven funnel as a fiber web. An output opening is arranged at the output side. Between the inlet side and the outlet side at least one guide surface is arranged for the fiber fleece in order to guide the fiber fleece flowing into the fleece funnel in the direction of the outlet opening. Background technique [0002] A nonwoven funnel for a textile machine for forming a belt is known from DE 10 230 433 A1. Nonwoven fabric funnel with back loop opening The fiber strip is discharged from the nonwoven funnel through the decoil opening. Collision and / or guide surfaces are arranged opposite the decoil opening o...
