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...
