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 nonwoven funnel for compressing fibrous nonwovens, in particular at a drawframe, card or comber, with: an inlet side (2) configured elongately in the x direction, at which A fibrous nonwoven fabric stretched at one side and constructed of individual fibers enters the nonwoven fabric funnel (1); and an output side (3) spaced apart from the input side (2) in the z direction, at the The fibrous nonwoven fabric at the output side is discharged from the nonwoven fabric funnel (1) as a fiber strip; an output opening (4), which is arranged at the output side (3); and at least one Guide surfaces (5a, 5b) for the fiber nonwoven arranged between the input side (2) and the output side (3) in order to guide the fibers flowing into the nonwoven funnel (1) The fleece is guided in the direction of the delivery opening (4). According to the invention, at least one guide element (6, 12) is arranged in the region between the inlet side (2) and the outlet opening (4), said at least one guide element delimiting the fiber nonwoven Partial movement in the x-direction and / or in the y-direction, wherein the guide element (6, 12) is arranged in such a way that it passes through the guide surface (5a, 5b) towards the output opening ( 4) prevents the fibers from colliding at least in the x-direction after the fiber nonwoven is reversed.

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...
