Abstract:
1. An apparatus for extruding an outer material onto an extruded product with one or more longitudinal stripes incorporated onto the surface of the extruded product comprising: a body having a substantially tubular shape, an upstream end and a downstream end; a primary feed conduit extending through the body for conveying a primary extrusion material; a secondary feed conduit mounted downstream of the primary feed conduit for conveying a secondary extrusion material; a primary extrusion head mounted in the body; a secondary extrusion head mounted in the body downstream from the primary extrusion head; a die retainer mounted to the downstream end of the body; a striping die with an upstream side and a downstream side, wherein the striping die is mounted in the die retainer downstream of said secondary extrusion head; a striping die adapter removably connectable to the downstream side of said striping die; and a striping feed conduit extending through the striping die adapter for conveying striping extrusion material; wherein the upstream end of the striping die comprises one or more striping extrusion outlets for delivering striping extrusion material onto the extruded product; the downstream end of the striping die comprises a flow channel in fluid communication with the one or more striping extrusion outlets; and the flow channel is wishbone-shaped.
