Means for mechanically isolating and for manipulating fibers so as to place them in condition for the purpose for which they are to be utilized. Includes the bringing together of the fibers into laps, slivers, and the like, but not twisting or interlacing into permanent form.
(1) Note. Patents directed to the feeding of material to a named fiber treating machine, combined with fiber treatment, are classified in the appropriate subclasses in this class.
