Abstract

The method is intended for controlling the width of the outlet (2) gap (5) of a die (1) for extruding material in the form of a layer, this gap being defined by parallel lips (6,7) and its width being controlled via transversely spaced units (8) each comprising at least one rod (9) expanded and contracted by heating (15) and cooling (23,24) and acting on at least one lip (7). For each unit (8), heating is individually controlled in response to the corresponding measured thickness of the extruded material whilst cooling is common to some or all units and is effected by passing a coolant transversely along their rods whereby the supply temperature of the coolant may be controlled.
