摘要： The present invention is concerned with a method and apparatus which blend components of a thermoplastic resin composition in an extruder having a cylindrical body, a screw, and a heating means, wherein the cylindrical body has a large bore part, a tapered part, and a small bore part, and the screw has a large diameter flight, a tapered flight, and a small diameter flight which is fitted within the cylindrical body. The tapered flight has free pass recesses, if desirable, and the roughness of the inner surface of the cylindrical body and/or roughness of the outer surface of the flight of screw are decreased as one proceeds in the direction from the small bore part to the outlet.

摘要： Disclosed is a compact and convenient apparatus for producing corrugated cardboard, which solves or at least lightens the problem that the plant is too long. In this apparatus a component (I) for completing a single facer corrugated cardboard is disposed on the first floor (G); a component (II) for preparing incomplete corrugated card board on the second floor deck (U); a component (III) for obtaining the complete corrugated cardboard on the slope which goes down gradually and linearly from the second floor deck to the first floor; and a component (IV) for drawing the product corrugated cardboard and delivering to the next processing steps on the first floor.

摘要： Disclosed is an improved method of producing corrugated cardboards, in which water suspension of raw starch is used as an adhesive. The raw starch is, after application thereof, heated to form gell or paste with dry steam prepared by reheating low-pressure steam with high-pressure steam. Also, disclosed is an apparatus for practicing the improved method.
