    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 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.

    摘要翻译： 本发明涉及一种用于吹塑薄膜生产线的折叠刀片以及配有吹塑薄膜生产线的吹塑薄膜生产线。 折叠刀片用于横向折叠，运行到起飞夹送辊的薄膜气泡。 如果它们深深地融入到电影泡沫中，则在后侧设置有翅片，并且被称为深折叠片。 本发明提出，折叠刀片的后侧配备有翅片，其具有带有调节装置的可折叠元件。 因此翅片的体积可以变化。 特别地，翅片可以平放在折叠刀片的后侧。

    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.
