摘要： A nonwoven web is made by first depositing fibers as a nonwoven web in a deposition area, then conveying the web away from the deposition area in a web-travel direction, preconsolidating the web in the path, and passing the preconsolidated web between a pair of rollers that compress and final consolidate the preconsolidated web, One of the rollers is separated from the web such that final consolidation of the web at a starting level is stopped and at the same time or immediately beforehand upstream preconsolidation of the web increased. After separating the one roller from the web, another roller is engaged with the web at the consolidation station and then final consolidation is recommenced, whereupon upstream preconsolidation of the web is reduced back to the starting level.

摘要： In blown film installations, it is known to provide longitudinal stretching of the produced double layer film strip downstream of the draw-off, more precisely downstream of the reversing unit and upstream of the winder. It is also known to stretch the down-drawn film, wherein the film must then be preheated owing to the long cooling path from the draw-off. According to a first feature, the present invention specifies warming the film above the draw-off and then treating it mechanically. The film can thereby be brought with only little energy from a first level of warmth to a temperature level at which it can easily be worked. According to a second feature, the invention specifies providing a tractive force breakdown brake.

摘要： The invention relates to a device for producing a spun-bonded web from filaments, comprising spinnerets, a cooling chamber into which process air can be introduced in order to cool the filaments, a monomer suction device arranged between the spinnerets and the cooling chamber, a stretching unit, and a placing device for placing the filaments so as to form the spun-bonded web. The cooling chamber is divided into two cooling chamber portions. Process air can be suctioned out of a first upper cooling chamber portion to the monomer suction device with a volumetric flow rate Vm, and process air exits the first upper cooling chamber portion into a second lower cooling chamber portion with a volumetric flow rate V1. The volumetric flow rate ratio VM/V1 is 0.1 to 0.3.

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： A method of making a spun-bond nonwoven fabric of thermoplastic filaments has the steps of first spinning the thermoplastic filaments, then cooling the spun filaments, and then conducting the cooled and spun filaments in a travel direction through a stretcher with primary air such that the primary air exits a downstream end of the stretcher with the filaments at a predetermined primary air volume/flow VP. The filaments and substantially all of the primary air are passed together as a flow from the downstream end of the stretcher into a diffuser. Secondary air is introduced into the flow at a secondary air volume/flow VS such that a ratio VP/VS of the primary rate VP to the secondary rate is equal to at least 4.5 and the primary and secondary air flow with the filaments in the travel direction through the diffuser.

摘要： The invention relates to a folding blade for a blown film line, as well as to a blown film line equipped therewith.Folding blades are used for laterally folding in a film bubble running to the take-off pinch rolls. If they engage deeply into the film bubble, they are provided with a fin on the rear side, and referred to as deep folding blades.The invention proposes that the rear side of a folding blade be equipped with a fin, which exhibits a collapsible element with an adjustment device. The volume of the fin can thereby be varied. In particular, the fin can be laid flat against the rear side of the folding blade.

摘要： An apparatus for making a spunbond web has a deposition surface, a spinneret above the surface for producing filaments that move downward along a path toward the surface, and a cooling chamber below the spinneret. Cool process air is supplied to the chamber to cool the filaments as they pass downward through the chamber. A laterally closed stretching unit downstream of the cooling chamber has laterally closed side walls that have portions that diverges downward. A connecting region between the stretching unit and the cooling chamber substantially excludes access of air from outside to the filaments as they pass from the cooling chamber to the stretching unit so that the filaments drop from the stretching unit onto the deposition surface.

摘要： A laminate has first and second spunbonded nonwoven layers at least one of which comprises or consists essentially of crimped continuous filaments that are bicomponent filaments having a first component based on polypropylene and a second component based on polypropylene. A specific density ρ (g/cm3) of the spunbonded nonwoven laminate depending on the surface density of the spunbonded nonwoven laminate lies below a density limit ρG defined by the following equation:

ρG=9 cm−1×surface density g/cm2+0.0393 g/cm3.

摘要： A nozzle has a body having a face extending in a longitudinal direction and transversely thereto in a transverse direction. The nozzle plate is provided with an array of melt openings and compressed-air openings on the face in a plurality of longitudinally extending rows and a plurality of transversely extending rows. A polymer melt to the nozzle openings to extrude the polymer melt downstream from the melt openings as polymer filaments and compressed air to the compressed-air openings to form air jets issuing downstream from the compressed-air openings between the polymer filaments. Only the polymer melt and no air is supplied to the melt openings such that only the polymer melt issues from the melt openings. Only compressed air and no polymer melt is supplied to the compressed-air openings such that only the compressed air issues from the compressed-air openings.
