    摘要: A process for the manufacture of a thermoplastic blown film is disclosed. The process includes the step of extruding a blown film tube of a thermoplastic material. The outside surface of the film tube is treated with a cooling gas to solidify the film tube. This cooling gas is directed to the tube from an annular ring around the tube and the cooling gas is directed at the tube in a flow direction parallel to a wall of the film tube. The cooling gas is drawn off the tube by means of a suction ring positioned around the tube prior to flattening the tube to form a film.

    摘要: A process and apparatus for separation of solvents from an air stream laden with solvent vapors by adsorption using active carbon followed by regeneration of the carbon by desorption by steam using a plurality of active carbon chambers. The sequence of charging and regeneration of the active carbon is controlled automatically in dependence upon the concentration of solvent vapors in the air stream. During the change over from charging to regeneration the active carbon is first subjected to desorption by steaming with a large volume of steam and then, when steam breaks through on the outlet side of the carbon the volume of steam is reduced for the purpose of drying the carbon. The change over is effected by a measuring device arranged on the outlet side of the carbon chamber responsive to a pre-determined threshold concentration of solvent vapors in the outgoing stream.

    摘要: A take-off apparatus for plastic blown sheet that is collapsed has a deflecting roller rotatably mounted for transporting the blown sheet and an air turning bar for receiving the blown sheet from the deflecting bar along a transport plane defined therebetween. The blown sheet passes around a peripheral portion of the air turning bar thereby defining a support arc region of the at least one air turning bar about which the blown sheet is supported. The air turning bar has air outlet openings disposed in the support arc region through which compressed air is ejected to support the blown sheet. The air turning bar has an arc-shaped axis defining a plane of curvature which is oriented such that the peripheral portion presents a concave surface in which the air outlet openings are disposed and which opposes the blown sheet.
