Abstract

A spun-bond web production apparatus comprises a spinneret for producing descending thermoplastic synthetic resin filaments; receiving device for receiving filaments; continuously movable collecting foraminous belt; and at least two mutually independently controllable suction zones beneath the belt for drawing air and including a primary suction zone at which a greater part of the filaments are drawn onto the belt. A spun-bond web production apparatus comprises a spinneret (1) for producing descending thermoplastic synthetic resin filaments; receiving device below the spinneret and receiving filaments for aerodynamically stretching the filaments; continuously movable collecting foraminous belt (7) displaceable longitudinally in a web-producing direction below the receiving device to produce a spun-bond web; and at least two mutually independently controllable suction zones (11) beneath the belt for drawing air through and in succession in the web-producing direction, and including a primary suction zone at which a greater part of the filaments are drawn onto the belt and at least one other suction zone.

Description

technical field

[0001] The present invention relates to an apparatus for the continuous production of spunbonded nonwoven webs from aerodynamically stretched thermoplastic monofilaments. Background technique

[0002] The spinneret has many spinning orifices through which thermoplastic monofilaments can be extruded. Within the scope of the invention, the monofilaments first pass through a cooling chamber into which process air for cooling the monofilaments can be fed from an air supply chamber. The monofilament then expediently reaches a stretching unit with a down-draw channel, to which a lay-up unit is connected, which preferably consists of at least one diffuser. A stacking device for stacking monofilaments into a spunbonded nonwoven web is arranged below the laying unit, wherein the above-mentioned continuously movable stacking mesh belt is an integral part of the stacking device. Monofilaments are laminated on this laminated belt to form a spunbonded nonwoven fabric. ...
