An apparatus is provided for manufacturing a fiber reinforced elastic sheet by extruding and processing an elastomer containing staples by 25 volume % or less. The apparatus includes a flow adjustment portion provided in a flow path direction of the elastomer for insuring a uniform flow of the elastomer in a sheet width direction. A weir portion is provided on the downstream side of the flow adjustment portion. A clearance Wo of an outlet in the vertical direction of the sheet, a clearance Wi formed by the weir portion in the vertical direction of the sheet and a distance l between the weir portion and the outlet have the relationship of

Apparatus for manufacturing fiber reinforced elastic sheet

A method for manufacturing a fiber reinforced elastic sheet by extruding and processing an elastomer containing staples by 25 volume % or less. The elastomer, which uniformly flows in a sheet width direction, passes through a slight clearance of a molding die in the vertical direction of the sheet, and then the elastomer flow is enlarged in the vertical direction of the sheet. A flow adjustment portion is provided in a passage of the elastomer to flow uniformly in the sheet width direction, and a weir portion is provided on the downstream side of the flow adjustment portion. A clearance Wo of an outlet in the vertical direction of the sheet, a clearance Wi formed by the weir portion in the vertical direction of the sheet and a distance l between the weir portion and the outlet have the relationship of

A roller for running a flat belt is formed at its surface by an elastic body. Short fibers are mixed with the elastic body. The short fibers are averagely oriented in a direction radially or peripherally inclined to the roller with a small angle and protrude at their tip portions from the roller surface. Owing to a grip force of the protruding short fibers, the flat belt is running, while decreasing a friction coefficient and obtaining a stability to a variation of temperature and humidity. The short fibers may be oriented in a direction axially, peripherally inclined thereto with a specific angle. When a belt guide member is provided to the roller or flat belt, accurate running of the belt is performed.
