There are provided screw segmentsthat are capable of shearing and kneading feedstock without causing plugs within a cylinderof a screw extruder, and of extruding it from the cylinder. The screw segmentseach comprise a shaft partto be affixed to a screw shaft, and a tooth partthat protrudes radially outward from the shaft part. The tooth partcomprises a tooth surfacethat is formed on the front side relative to the rotation direction of the screw shaft, and that is so sloped as to transition gradually forward relative to the rotation direction as it transitions radially outward from the shaft part

Screw segment

A seal ring is provided which allows the interior of a cylinderof a screw extruder to be maintained at elevated temperature and elevated pressure, thus suppressing a variation in the pressure in the cylinder. In a special seal ringattached to a screw shaftin the cylinder of the screw extruder so as to be rotatable integrally with the screw shaft, thus restraining a material to be treated from being fed from upstream to downstream in the cylinder, a lead grooveextending in an axial direction of the shaftis formed in an outer circumferential surfaceopposing with a predetermined gap to an inner circumferential surfaceof the cylinder. The lead grooveserves to disturb the flow of the material to be treated passing between the outer circumferential surfaceand the inner wall surfaceof the cylinderto complex the flow. This stabilizes feeding resistance to suppress a variation in the pressure in the cylinder

Seal ring

A toothed belt has therein a core wire () including a core thread () made of aramid fiber and a filament thread () made of nylon fiber, and has belt tooth portions () and belt groove portions () alternately formed therealong. The core wire (), the belt tooth portions (), and the belt groove portions () are integrated with one another by a rubber material (). It should be noted herein that the core thread () and the filament thread () are integrally twined around each other so that the filament thread () is formed in the shape of a plurality of loops around the core thread (). The filament thread () in the shape of the loops enters tooth root portions () of the belt tooth portions () to be arranged therein. As a result, the tooth root portions () are strengthened.

A method is provided for producing an integral skin foam article made up of a skin, foam and core member. According to the method, an expanded layer which is of the same material as the skin is formed on the back of the skin prior to forming the article.

The foam slush molding apparatus of this invention comprises a mold and a hot air jacket, and an optional heat retaining hood. The hot air jacket and the optional heat retaining hood are provided along and a certain distance apart from the molding surface on which a resin is heated and fused. The molding surface and the jacket form a first hot air chamber for heating, and the jacket and the optional heat retaining hood form an optional second hot air chamber for heat retention. The apparatus permits uniform heating and foaming at an efficient molding cycle.
