摘要： An off-drawing apparatus for tubular webs of plastic film produced by an extruder with a fixedly disposed blow head includes a lay-flat apparatus for the tubular web delivered with an expanded round cross section, and a stationary conveyor for carrying off the flattened tubular web to a likewise stationary winding apparatus. Between the lay-flat apparatus and the conveyor there is disposed at least one pulley roll and one overturning bar for turning the tubular web 180.degree. with simultaneous change of direction, which, like the lay-flat apparatus, are supported in an apparatus frame for pivoting reversingly in a horizontal plane about the axis of the delivered tubular web. The lay-flat apparatus, the pulley roll and the overturning bar are held for their reversing pivoting movement on swivel rings disposed one over the other and supported directly on one another through interposed rolling bodies which form together a swivel ring stack rotatably mounted in the apparatus frame and compressively stressed, whose inside diameter is at least equal to the maximum working width of the apparatus.

摘要： A composite sheet material especially suited as a roofing material is disclosed. The sheet is a composite of extruded top and bottom layers. The top layer is formed by extrusion of a mixture of cured rubber particles dispersed in a matrix of polypropylene. The bottom layer is formed by coextrusion with the top layer of a mixture of calcium carbonate and cured rubber particles dispersed in a matrix of polypropylene. The method of fabricating the composite sheet material includes trimming longitudinal edges of the material with powered circular blades as it moves between chill rollers and a pull roller assembly. The material is spooled with minimum winding tension so as to prevent tension forces from being set in the material.

摘要： A device for making a spun fleece has a spinning nozzle or spinneret system, a cooling shaft, a stretching gap, a diffuser shaft, a continuously moving fleece receiving conveyor and a device for feeding process air and for pulling or removing outflowing air through the fleece receiving conveyor. The cooling shaft has a shaft wall provided with a plurality of air orifices. Because of that process air required for the cooling is fed into the cooling shaft. The air flow at least partially is pulled through the fleece receiving conveyor and the spun fleece formed by the deposited endless filament loops. The deposited length of the endless filament loops is measured over the spun fleece width in the finished fleece. The measured value is compared with a predetermined set value. On deviation of the measured value from the set value the setting angles of the air control flaps pivotable about a horizontal axis which are located at the entrance of the stretching gap are changed. On a positive deviation of the measured value of the thickness from the set value the setting angles are decreased (deposited length larger than the set value).

摘要： The thickness of a cut length of a continuously extruded elastomer is controlled by sampling the weight of a section of the continuous extrusion at a running-weigh-scale each second; computing and storing one-minute averages of the running-weigh-scale samples; sampling the weight of a cut length of the extrusion at a check-weigh-scale; comparing the check-weigh-scale value to the oldest stored running-weigh-scale one-minute average to obtain a targeted average; comparing the targeted running-weigh-scale average to the newest stored running-weigh-scale one-minute average to obtain a deviation from the targeted value if one exists; and converting the deviation from the targeted running-weigh-scale value to a control signal for increasing or decreasing the speed of a take-away belt positioned at the extruder exit orifice to vary the thickness of the extrusion in accordance with the deviation control signal and the speed of the belt.

摘要： The technique uses an extruder for delivering a supply of softened thermoplastic resin material containing a foaming or expanding agent, the resin material being under pressure and therefore unexpanded in the extruder, but being delivered into a unconfined zone of lower pressure for partial expansion. The partially expanded resin material is drawn by a puller mechanism through a chilled shaping or sizing die of a cross sectional dimension smaller than that of the material in the unconfined zone. The material drawn into the sizing die continues its expansion in the interior of the profile with resultant development of porosity in the core of the profile while the surface layer is cooled and hardens as a substantially unexpanded structural shell.
