An extrusion apparatus for producing sheet-material in great width dimensions and consisting at least partly, of a thermoplastic material, in which one and the same die channel in a wide-orifice extrusion die is supplied with melted thermoplastic material through direct communications from at least two extruders, at least one of which is supported for movement in the axial direction of the die to compensate for thermal expansion thereof. The sheet-material extruded from the die is conveyed to by means of a roller system which is mounted to be displaceable traversely to the axial direction of the die to provide access for cleaning and adjustment thereof. |
