摘要:
A cooling apparatus includes a conveying means which conveys a resin composition formed into a sheet shape along a direction parallel to a surface of the sheet-shaped resin composition and a cooling means which cools the resin composition being conveyed by the conveying means. A temperature of the resin composition just before being cooled by the cooling means is in the range of 40 to 60° C. and the cooling means has a cooling ability to cool the resin composition such that a cooling rate of the resin composition is in the range of 0.2 to 5° C./min. Further, the cooling means includes a fan section having at least one outlet port which discharges cooling air of which temperature is in the range of −40 to 0° C. to the resin composition.

A pulverizing apparatus for pulverizing a hard resin composition has a pulverizing mechanism having a pair of rollers arranged parallel to one another, these rollers pulverizing the hard resin composition by pressuring the hard resin composition between the rollers and a cooling device for cooling the hard resin composition during the hard resin composition being pulverized. Each of the rollers has a cylindrical shape with a hollow portion and the cooling device is configured to supply a coolant into the hollow portion of each of the rollers. The coolant flows in the hollow portion of each of the rollers in a longitudinal direction of each of the rollers. The cooling device has facilitating members respectively inserted into the hollow portions of the rollers.

A degassing apparatus 1 includes a housing 2 having a degassing chamber 22, a rotor 3 rotatably provided in the housing 2 and a decompressing mechanism 4 for decompressing the degassing chamber 22 of the housing 2. The housing 2 further includes a conduit line 21 and a cylindrical portion 23. The degassing chamber 22 is provided in a middle part of the conduit line 21. An upper end of the conduit line 21 constitutes an inlet port 24 and a lower end of the conduit line 21 constitutes an outlet port 25. The rotor 3 is rotatably provided inside the cylindrical portion 23 so that a passage between the outlet portion 25 and the degassing chamber 22 can be hermetically separated by the rotor 3. The rotor 3 has four partitioning plates 31 which partition the inside of the cylindrical portion into four spaces 231-234.
