Patent ID: 7574875

Claim:
A method for the chemical deposition of synthetic material on an elongated substrate member having a longitudinal axis, comprising the steps: a) securing one end of said elongated member in a gripping member; b) imparting rotation about said longitudinal axis to said elongated member through said gripping member; and c) depositing synthetic material on said elongated member, and further comprising the step of radially constraining at least one end of said elongated member with respect to said longitudinal axis at two positions spaced apart along said longitudinal axis by contacting a first radial constraint member to the elongated member at a first of the two positions and contacting a second radial constraint member to the elongated member at a second of the two positions, the first and second radial constraint members each having a proximal end and a distal end with respect to the at least one end of said elongated member, the distal end of the first radial constraint member being adjacent to the proximal end of the second radial constraint member.
