A method for forming a composite extrusion is disclosed, wherein a continuous length is formed having a leading length and a trailing length, the leading length including the primary extrudate and a first appendage extrudate and the trailing length including the primary extrudate and a second appendage extrudate, wherein the first appendage extrudate and the second appendage extrudate are formed form corresponding interchangeable first and second insert dies. The continuous length of the composite extrusion includes (i) the leading length having the primary extrudate and the first appendage extrudate; (ii) a change over length having the primary extrudate; and (iii) the trailing length having the primary extrudate and the second appendage extrudate, wherein a plurality of individual weatherseals can be cut from the leading length, and a plurality of weatherseals can be cut from the trailing length.

A method of forming a composite extrusion, comprising:(a) extruding a primary extrudate through a primary die block; (b) extruding, during extrusion of the primary extrudate, a first appendage extrudate through a first die orifice of a first insert die coupled to the primary die block to contact

1. A method of forming a composite extrusion, comprising:(a) extruding a primary extrudate through a primary die block; (b) extruding, during extrusion of the primary extrudate, a first appendage extrudate through a first die orifice of a first insert die coupled to the primary die block to contact the first appendage extrudate with the primary extrudate to form a leading length of the composite extrusion; (c) replacing, during extrusion of the primary extrudate, the first insert die with a second insert die; and (d) extruding, during extrusion of the primary extrudate, a second appendage extrudate through a second die orifice of the second insert die to contact the second appendage extrudate with the primary extrudate to form a tailing length of the composite extrusion.
