摘要： PROBLEM TO BE SOLVED: To provide a cylindrical film manufacturing apparatus capable of manufacturing a cylindrical film having stable quality.
SOLUTION: A multilayered film formed into a cylindrical shape by a mold part 20 is successively folded in a folding part 40 while passed through the gap between guide members 41 and 41 to reach rollers 42 and 42 so that the cylindrical cross section thereof becomes a flat cross section. At this time, the distance H from the lower end part of a reticulated body 35, where the cylindrical cross section of the multilayered film is kept, to the rollers 42 and 42, where the multilayered film is perfectly folded into the flat cross section, is set to H/W≥1.8 with respect to the holding width W of the multilayered film in a folded state to prevent the occurrence of wrinkles when the multilayered film is folded.

摘要： PROBLEM TO BE SOLVED: To provide an extrusion molding machine capable of preventing the lowering of product quality by performing the stable supply of a raw material while preventing shearing force from acting on a raw material resin, and a screw member.
SOLUTION: The quantitative supply of the raw material resin is enabled by more reducing the volume V between a cylinder 21 and a shaft 31A per one pitch of a flight 32A at the part just under a hopper 22 than that of another part. By this constitution, the quantitative supply of the raw material resin becomes possible without using a quantitative feeder and the stable supply of the raw material corresponding to the rotational speed of a screw 30A in a real time can be also performed.

摘要： PROBLEM TO BE SOLVED: To provide an extrusion molding die eliminating the involution of air even at a time of high speed molding to enhance the close adhesiveness of a molten resin molding a sheet good in surface smoothness without generating cooling irregularity. SOLUTION: A passage of a molten resin 9 is formed between fixed blocks 1, 2 and a variable block 6 is provided to the leading end part of the fixed block 2 so as to be made displaceable in the direction shown by an arrow by a variable block adjusting bolt 4. A resin passage is formed between the variable block 6 and the surface of a cooling roll 8 and the pressure loss in the resin passage is measured by a pressure gauge 7. On the basis of the pressure loss measured by this pressure gauge, the gap of the die lip (g) to the cooling roll 8 is controlled so as to apply pressing force capable of excluding involved air when the measured value is in the vicinity of zero.
