摘要： PURPOSE:To obtain a sheet having a woodgrain pattern, checkered pattern or the like by rotatably placing specified rotor blocks in the passages communicating between a plurality of manifolds and a die lip and varying the quality and color of molding materials in the width direction of a sheet. CONSTITUTION:A small mover block 7 is mavably placed in the small passage 6 penetrating through a rotor element 5. A rotor block 9 formed by coupling a plurality of such rotor elements 5 so that their small passages 6 are not aligned with each other is rotatably placed in one 4a of communicating passages 4 between manifolds 2 and a die lip 3, each small mover block 7 being capable of movement by the pressure of a molding material 8. The second rotor block 12, which is provided with a mover block 10 in the passage 11 so that the block 10 can be moved by the pressure of a molding material 13, is rotatably placed in the remaining communicating passage 4b. Changing the coupling positions of the rotor elements 5 so that the positions of the small passages 6 vary from each other permits sheets having various kinds of patterns to be formed.

摘要： PURPOSE:To measure a volume flow distribution by a method wherein revolutions of a plurality of rolls provided outside a lip of a die to mold sheet through extrusion and also widthwise of the sheet are detected on a light source and a light receiver, and a vertical oscillation of the rolls is detected on a thickness detector. CONSTITUTION:A fused molding material 16 is extruded continuously as a sheet 1 through a lip 3 of a die 2. The sheet 1 is fed between an upper roll 4 and a lower roll 5, and the light of a light source 8 provided on a mounting frame 7 is detected on a light receiver 9 through a hole 6 according to rotations of the upper roll 4. Such a detecting unit 22 is arranged in a plural piece widthwise of the sheet, therefore an extrusion rate distribution of the sheet 1 can be measured. Then, a vetical oscillation of the roll 4 according to fluctuation in thickness of the sheet 1 is detected on a thickness detector 10. Thus a volume flow distribution of the sheet 1 is measured to obtain the sheet uniformly.

摘要： PURPOSE:To obtain a piece uniformly and tightly coated with a plastic, by coating a primary plastic layer on a substrate by a pressure method and coating a secondary plastic layer on the primary one by a sheath method. CONSTITUTION:When a substrate 4 is conveyed in the direction of an arrow, primary molten plastic 7 squeezed by a lip 8 and flows down is thrusted by a roll 9 and coated on the substrate 4 in a pressure coating process. Secondary molten plastic 11 flowing down from another lip 12 is coated on a primary plastic layer 22 by a gap adjusting plate 15 in a sheath coating process. This results in providing a plastic-coated piece 20. EFFECT:The advantages of both a pressure method and a sheath method are utilized to enable uniform and tight coating and facilitate coating on the joint of a substrate. Any additional process for a perforated substrate is not needed.
