    摘要： There is disclosed a system for controlling an extrusion line for foamed insulation cables. In this system, a foaming insulation compound composed of a polyolefin resin and a foaming agent is supplied to an extruder (17), and extruded and coated as a foamed insulation onto a continuously fed cable conductor (13) at a temperature higher than a decomposition temperature of the foaming agent to produce a cable that is subsequently passed through a cooler unit (27) for controlling the outside diameter and electrostatic capacity of the foamed insulation. The system is controlled so that a plurality of measured variables including a plurality of controlled variables such as the outside diameter and the electrostatic capacity and condition variables affecting the controlled variables, such as a cylinder temperature of the extruder, a crosshead temperature of the extruder, a resin temperature and a resin pressure in the crosshead, are variable in predetermined correlation with a plurality of manipulated variables as input parameters which vary the controlled variables, such as a line speed of the extrusion line, a voltage applied to a preheater disposed in front of the extruder, an RPM of a screw in the extruder, a voltage applied to a cylinder heater in the extruder, a voltage applied to a crosshead heater, and a distance which the cooler unit is movable. The controlled variables are controlled so as to be adjusted into target values therefor by manipulation variables which are produced by effecting an integrating action on variable factors which are derived from the differences between the target values and the controlled variables.

    摘要： The present invention provides a production method for a microporous polyolefin resin sheet which enables the stable formation of a sheet having uniform crystallinity, even when the speed of the casting cooling device is high, and has excellent thickness uniformity and appearance grade.
    The production device for a microporous polyolefin resin sheet according to the present invention includes a mouthpiece that extrudes a molten resin in a sheet shape; a casting cooling device that cools and solidifies a sheet extruded from the mouthpiece while conveying the sheet; and a decompression chamber that is installed upstream from the mouthpiece in a conveying direction of the casting cooling device and aspirates air between the sheet extruded from the mouthpiece and the casting cooling device; and further includes a rectifier that is installed and blocks a gap between the sheet discharged from the mouthpiece and the cast surface. The decompression chamber of the production device for a microporous polyolefin resin sheet according to the present invention includes: a sealing member provided in at least a peripheral portion of a surface opposing the casting cooling device and in physical contact with the casting cooling device; and a partition plate provided across a sheet width direction in a vicinity of an opening part opposing the mouthpiece.

    摘要： An apparatus (10), such as an extruding machine (10), configured to form a sheath (26), e.g. insulative layer, over an elongate member (14), e.g. a wire cable (14) including an extruder (12) to apply the material forming the sheath (26), a drive mechanism (28) configured to move the elongate member (14) through the extruder (12) at a line speed, a thickness sensor (34) to determine the thickness of the material, and a controller (36). The controller (36) is programmed to determine a deviation between the actual material thickness a desired thickness, determine a correction factor value based on the deviation between the actual thickness and the desired thickness of the material applied, and adjust the line speed, via the drive mechanism (28), based on the line speed, an extruder (12) feeder speed, the correction factor value and a material factor value that is based on rheological properties of the material. A method (100) of operating such an extruding machine (10) is also presented.
