A die assembly is described for causing extrudate to bend without substantially changing the cross sectional shape of the extrudate. The assembly includes a die mounted in spaced relation from a feed channel through which extrudate passes from the extruder including a first part which has a flow channel which has at least one pair of sidewalls which converge from the die in the direction of the extruder. A second part of the assembly has a feed opening for directing extrudate into the flow channel. It provides for varying the length of the pathways which extrudate flows through the flow channel to a pair of opposing sides of the die to cause bending of the extrudate in the direction of the longest pathway as the extrudate exits the die.

A die assembly used in connection with an extruder for bending extrudate as it flows from the assembly, comprising: (a) a die and means for mounting said die spaced from a feed opening of the assembly to form a flow channel therebetween, the die having a die opening which is positioned such that extrudate flows from an extruder successively through the feed opening, flow channel and the die opening, and (b) means for angularly moving the die opening with respect to the feed opening of the assembly for varying the length of the flow channel to variably direct the flow of the extrudate along pathways of varying length through the flow channel to bend the extrudate as it exits the die opening.
