Abstract
An adjustable feedblock configured for adjusting the thicknesses of each layer of the juxtaposed extrudates forming a laminate. The feedblock includes at least one pair of opposing combining planes and at least one pair of opposing extrudate distribution blocks that are removably disposed within the housing of the feedblock. As such, the combining planes and the extrudate distribution blocks partially define portions of the flow paths for the extrudates that form the laminate within the housing of the feedblock. A method for forming a laminate having juxtaposed layers of extrudates of adjustable thicknesses is also disclosed.
