  • Patent number: 5904418
    Abstract: A sheet-testing apparatus including kneading rolls, a frame feeder, sheet applicator, foreign material detector, a frame with a light transparent window and a cutter for cutting a sheet. A sheet-testing sample-making apparatus has a cluster of kneading rolls, frame feeder, and sheet applicator. A sheet thickness detection apparatus outputs an electric signal to a memory. A kneading apparatus has a pair of heating rolls separated by a gap. The directions and speeds of rotations of the rolls are adjustable. A sensor detects the gap and a bank sensor detects the condition of a bank in the gap. The distance between the rolls, their temperatures, rotations, and speeds are automatically controlled. A pair of blades peel a sheet from the sheet-winding roll. Material dropped through the gap between the heating rolls is returned to a point above the gap. A cutting device has a length of wire sprung onto a rolled sheet to sever the sheet.

  • Patent number: 5433522
    Abstract: A hydraulic control device for a closed type kneader, including a sealing surface pressure applying circuit for applying a sealing surface pressure to a sealing device for sealing a rotor accommodated in a kneading chamber, a drop door driving circuit for controlling an opening and closing operation of a drop door for closing a bottom surface of the kneading chamber, and a power circuit for supplying a pressure oil to the sealing surface pressure applying circuit and the drop door driving circuit. The sealing surface pressure applying circuit is connected to a pressure oil supply line in the drop door driving circuit for a closed condition of the drop door. Accordingly, when the application of the sealing surface pressure is unnecessary, that is, when the drop door is opened, the sealing surface pressure is prevented from being applied to the sealing device, thereby extending the life of the sealing device.

  • Patent number: 4455761
    Abstract: A water-wet polymer is extruded through a die plate. Free water formed by extruding action at the die plate is atomized and/or evaporated into an air stream. The die plate assembly discharges the rubber/moisture into a closely adjacent cone/funnel-receiver openly surrounding the die plate, and connecting to and discharging into a lesser diameter conveying tube. The die plate and surrounding funnel are enclosed by a chamber so that air, input tangentially into the enclosure, provides a swirling vortex air flow at the die plate assisting in severing and stripping rubber particles from the die plate.
