Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.

Abstract: Embodiments of the invention are used to provide ways of tire tread molding and retreading with a double tread rubber body having a unitary structure that comprises two treads in order to remove the need for buffing an oxide layer typically associated with tread molding and curing.
