摘要： PROBLEM TO BE SOLVED: To mold a polyester film free from a die line by subjecting only the lip on an anti-taking-over side among a pair of die lips to R processing or corner cut processing. SOLUTION: A die and die lips are formed so as to have a structure such that an R processing part 3 of 0.1-5.0mm, pref., 0.5-2mm or corner cut processing part is provided to the leading end of the die lip only on an anti-gaking-over side 32 among the die lips. R processing is an abridgment of round processing and the leading end of each die lip usually finished at a right angle is rounded to be formed into a circular arc shape. By this constitution, an extruded resin film is pulled rearwardly along the lip 32 on the anti-taking-over side to go away from the lip 31 on a taking-over side and, therefore, deteriorated matter becomes hard to adhere and the adhesion and growth of discharges are suppressed and no die line is generated.

摘要： PURPOSE:To prevent unevenness of a color and reduction of a strength from occurring in a molded article by ununiformity of a plasticized resin by a method wherein in a kneader of an injection molding machine formed by providing a screw having a prevention valve part for preventing a counterflow of a resin, a kneading action can be applied to the resin by the counterflow preventive valve part. CONSTITUTION:A kneader of an injection molding machine is provided with a screw 1a having a counterflow prevention valve part for preventing a counterflow of a resin. A fin is peripherally formed by a fin groove 5 inside a check valve 2a of a counterflow prevention valve part. In addition, a fin is formed by fin grooves 4, 6 in a screw of the counterflow prevention valve part. The both ends of the fin in a flow direction in the counterflow prevention valve are so tapered that the depth of the fin groove is gradually reduced for eliminating stagnation of a resin. The fin formed in the screw has an outer diameter slightly smaller the inner diameter of the check valve 2a and is formed by peripherally engraving a screw shaft. Furthermore, the both ends of the fin in an axial direction are so tapered that the depth of the fin groove is gradually reduced.

摘要： PROBLEM TO BE SOLVED: To provide a foamed sheet which is free from the generation of a trouble such as a curtain wall phenomenon and does not show a low magnification trend due to the dissipation of a foaming gas as well as a film molding device. SOLUTION: An extrusion die flow path A is formed inside an extrusion die 11 and the tip of the extrusion die flow path A is opened to the outside, and further, the extrusion die 11 is arranged in such a way that the tip of the extrusion die flow path A is set in close proximity to the outer peripheral face 13a of a cooling roll 13, leaving a gap between the tip and the outer peripheral face 13a. At the same time, a flow path between the die 11 and the roll 13 following the extrusion die flow path A is formed between the end part 24a (24b) of the extrusion die 11 and the cooling roll 13. Further the surface of a foam 16 discharged from the flow path between the die 11 and the roll 13 is cooled to form a skin layer 52a.
