Abstract: A novel construction of an extrusion die is disclosed wherein an integral portion of one of the die segments which defines a flow channel is deformable in such a manner so as to provide dimensional changes in such flow channel along the width thereof. Adjustment means are also provided so that the dimensional alterations may be controlled along the width of the die in such a manner so as to control the flow of thermoplastic material therethrough.
