摘要： An installation for producing a polymer melt for a porous film, in particular for a membrane film, comprises a planetary roller extruder. Said extruder is used to produce a flowable polymer melt from thermoplastics. The planetary roller extruder has a filling opening and a discharge side for delivering the polymer melt. A melt pump is further provided. The discharge side of the planetary roller extruder is connected to a downstream inlet side of the melt pump for further conveying the polymer melt. The connection is in the form of a pressure channel shielded from the ambient atmosphere or a pressure line shielded from the ambient atmosphere. The planetary roller extruder and the melt pump are designed and/or can be driven in such a manner that the polymer melt is applied or can be transferred under pressure at the melt pump on the inlet side.

摘要： An improved device for the uniaxial or biaxial stretching of plastics material portions by means of a stretching frame is characterised among other things by the following features: the stretching frame comprises two pairs of mutually perpendicular guide rails with clips for stretching a plastics material portion, which clips are movable away from or towards each other; the device is constructed such that in addition to the starting position at the beginning of a stretching process and the end position after performing a stretching process, the guide rails and thus the clips seated thereon are additionally movable into a loading position, and the loading position is arranged so that it lies asymmetrically within the stretching frame and is thus closer to at least one longitudinal side of the stretching frame than to the opposite side of the stretching frame.

摘要： A biaxially-oriented film for thermoforming is disclosed including at least 75% by weight polyethylene and at least 95% by weight polyolefins, based on the total mass of the film. The polyethylene has an elongation at break of at least 7 in the stress-strain diagram, wherein the stress-strain diagram is measured at a temperature of 10° C. below the melting point of the polyethylene and the melting point is determined by differential scanning calorimetry using a heating rate of 10° C. per minute. A process for producing such films and to the use thereof are disclosed. A process for producing shaped bodies from such films and to the shaped bodies themselves are disclosed.

摘要： A treatment machine for flexible material webs which can be passed through treatment furnaces is disclosed having at least two successive zones in an extraction direction (A) of the material web, a zone separation device in relation to the extraction direction (A) of the flexible material web. The zone separating device includes at least one air partitioning device (AC) having an injection device (AC-E) which extends transversely to the material web and is designed such that a gaseous fluid flow (S) extending up to the flexible material web is generated above it. The injection device (AC-E) is also designed such that the gaseous fluid flow exiting from the injection device (AC-E) impinges obliquely in the direction of the flexible material web and thus on the material web plane (E) formed by the material web at a blowing angle (α).
