surface of the hollow cylindrical substrate 88 to support the substrate 88 and to maintain
it in a coaxially aligned relationship with tube 14.
Swain also discloses that button 22 may be depressed and twisted either
manually or automatically to lock or unlock shaft 16 from a “load” position. For example,
the loading mandrel 110 may be suitably configured with a screwdriver blade-like
projection located at the end of finger 112 (see Figures 1 and 3).
Swain lacks a mechanism associated with said roll retainer shaft being actuated
by a rotating action of a mechanism associated with said roll loading shaft to move said
rolls along said roll retainer shaft, as called for in claim 1, or engaging means disposed
at an axial center of said roll loading shaft for engaging a ball screw disposed at an axial
center of said roll retainer shaft and rotating means for rotating said engaging means of
said roll loading shaft to thereby rotate said ball screw, wherein one of said rolls held on
said roll retainer shaft is transferred onto said roll loading shaft by a nut which moves
upon rotation of said ball screw, as called for in claim 4. Specifically, although Swain
discloses a mechanism (button 22, shaft 16, cam 87, cam follower 86, rails 42, 44 and
wheels 66, etc.) associated with the mandrel 10 actuated by a mechanism (on finger
112) associated with the loading mandrel 110 to move the rails 42, 44 and wheels
mounted thereon between a load position close to the central longitudinal axis of the
shaft 16 and a substrate supporting position, and vice versa, to facilitate loading and
unloading of the substrates on the mandrel assembly 10, Swain does not disclose a
