摘要： An apparatus for continuously making a spunbond web of filaments comprises a spinneret, a cooling chamber into which process air for can be introduced for the purpose of cooling the filaments, a monomer suction device between a spinneret and cooling chamber, a stretcher and a deposition device for depositing the filaments of the spunbond web. The cooling chamber is divided into two cooling compartments, and process air can be suctioned out from a first upper cooling compartment at a volumetric flow rate (VM) to a monomer suction device. Process air exits from the first upper cooling compartment at a volumetric flow rate (V1) into a second lower cooling compartment and from the first upper cooling compartment at a volumetric flow rate (V1) into a second lower cooling compartment. A ratio (VM/V1) is 0.1 to 0.35.

摘要： A web or fleece of synthetic resin strand collected on a sieve belt is discharged from the sieve belt into further processing equipment over a rerouting roller at the discharge end of the sieve belt. The rerouting roller is perforated and air or another fluid medium is passed through the belt at the rerouting roller to reduce adhesion forces between the belt and the web and lift the web from the belt without damage to the belt.

摘要： A fleece-making apparatus has a vertically extending and horizontally elongated process shaft having upper and lower ends, a nozzle head at the upper shaft end for emitting a multiplicity of continuous thermoplastic strands that descend in the shaft as a curtain, and a foraminous conveyor belt at the lower shaft end for receiving and conveying away the filaments. A main stream of air flows downward in the shaft from the upper shaft end to the lower shaft end and through the belt for cooling and stretching the filaments and depositing the filaments on the belt. A pair of horizontally elongated and downwardly open second inlet slots flank the curtain of filaments below the upper shaft end, a pair of horizontally elongated third inlet slots flank the curtain of filaments below the second slots, and a pair of horizontally elongated third outlet slots flank the curtain of filaments below the third inlet slots and above the lower end. A controller including at least one blower connected to the slots directs second streams of air downward into the shaft from the second inlet slots, introduces third streams of air into the shaft through the third slots, and withdraws air from the passage through the third outlet slots for looping the cooled and stretched filaments prior to deposition on the belt.

摘要： A spunbonded nonwovens is made by first spinning thermoplastic continuous filaments and emitting them from a spinneret in a direction and then passing the filaments in the direction through a cooling chamber. Meanwhile cooling air is fed from respective manifolds flanking the chamber into the chamber to cool the filaments and the cooling air is guided into the manifolds through respective manifolds and through respective planar homogenizing elements each having a plurality of openings forming a free open surface area constituting 1 to 40% of the total surface area of the respective planar homogenizing element. The cooling air passes from the planar homogenizing element into the cooling chamber through a flow straightener.

摘要： An apparatus for making spunbonded nonwovens has a spinneret for emitting continuous thermoplastic filaments in a filament-travel direction, a cooling chamber downstream in the direction from the spinneret for cooling the spun filaments with cooling air, two manifolds on opposite sides of the cooling chamber opening transversely of the direction into the cooling chamber, and a respective conduit having a conduit cross-sectional area and connected to each manifold for feeding cooling air thereto. The conduit cross-sectional area increases toward the manifold to a manifold cross-sectional area, and manifold cross-sectional area is at least twice as large as the conduit cross-sectional area. At least one flow straightener is provided upstream from the cooling chamber in each manifold for orienting air flow in an air-flow direction, and at least one perforated planar homogenizing element is provided in each manifold for homogenizing the cooling air flow.
