摘要： An apparatus for making spunbonded nonwoven has a spinneret for emitting the continuous filaments in a filament-travel direction, a cooling chamber downstream in the direction from the spinneret and receiving the filaments, and two air-supply manifolds flanking the chamber for feeding cooling air thereinto transverse to the direction. A flow straightener for equalizing flow of the cooling air on the filaments is provided in at least one of the air-supply manifolds and has passage walls forming a plurality of flow passages that extend transversely to a filament-travel direction. A flow cross section of the flow straightener is greater than 85% (preferably more than 90%) of a cross-sectional size of the straightener, a ratio of a length L of the flow passages to an inner diameter Di of the flow passages L/Di is 1 to 15.

摘要： An apparatus for making a spunbond nonwoven from endless filaments of a thermoplastic synthetic resin has a spinneret for spinning the filaments in a filament-travel direction into a spinning zone and a monomer aspirator downstream of the spinneret and having two vacuum intake ports flanking the spinning zone zone, horizontally confronting each other, and each extending transversely to the direction opposite one another. Suction means connected to the two ports withdraws gas through both the vacuum intake ports. The suction and/or the ports are set up to vary the flow through the vacuum intake ports such that substantially more gas flows through one of the ports than through the other.

摘要： An apparatus for making a spunbond nonwoven from monofilaments of thermoplastic synthetics has a spinneret for spinning and emitting the filaments in a travel direction, a cooler downstream of the spinneret for cooling the spun filaments, and a stretcher downstream of the cooler for stretching the filaments. An intermediate passage extending in the travel direction between the cooler and the stretcher has upstream and downstream converging passage sections. The upstream passage section in the travel direction of the filaments having a shorter length than the downstream passage section in the travel direction of the filaments. A ratio BE/BA of an inlet width BE to an outlet width BA of the upstream passage section is 1.5 to 5.5. A ratio of an inlet width bE, to an outlet width bA, of the downstream passage section is 1 to 4.

摘要： The invention relates to a device for producing spunbonds from endless filaments, comprising at least one spinneret, at least one cooling device, at least one stretching device and comprising at least one depositing device for depositing the filaments. At least one diffusor is arranged between the stretching device and the depositing device so that filaments and primary air from the stretching device enter into the diffusor. In the region of the at least one diffusor at least two secondary air inlet gaps arranged on opposite sides of the diffusor are provided. At least one secondary air inlet gap is formed with the proviso that the secondary air flows in at an angle a with respect to the filament flow direction FS, wherein the inflow angle a is less than 100°. An extraction device for extracting air through the depositing device. An extraction region arranged underneath the diffusor outlet has a width b in the machine direction which is greater than the width B of the diffusor outlet.
