APPARATUS FOR PRODUCING SPUNBONDED NONWOVEN FABRIC FROM ENDLESS FILAMENT

摘要

PROBLEM TO BE SOLVED: To provide a production apparatus for a spunbonded nonwoven fabric in which qualities of placed filaments or a produced nonwoven fabric web are adapted to all requirements despite a high filament speed, a small yarn count, and a high production speed.SOLUTION: The production apparatus for a spunbonded nonwoven fabric is provided with a deformable sealing material 2.2 for sealing a clearance 2.1 formed between a spinneret 2 and a monomer suction apparatus 4 and/or is provided with a deformable sealing material 7 for sealing a clearance 5 formed between the monomer suction apparatus 4 and a cooling apparatus 3 and/or is provided with a deformable sealing material 8 for sealing a clearance 6 formed between the cooling apparatus 3 and a drawing apparatus or an intermediate pipe line 11.1. The abutment characteristics of the sealing materials 2.2, 7, and 8, especially, a pressing force and/or a pressing pressure and/or an abutment area are variable or post-adjustable with respect to boundary surfaces of clearances 2.1, 5, and 6, respectively.SELECTED DRAWING: Figure 2
