Abstract

Method and apparatus for the collection of samples of staple fibers from a quantity (4) of such fibers, without material consideration of the 'condition' of the fibers within the batch, and thereafter physically converting each sample of fibers to a tapered beard geometry (102), employing a rotary carrier (104). Each beard (102) is grasped at one end thereof with the fibers thereof extending unsupported therefrom. The beard (102) is conveyed to a location proximate the entrance to an air flow channel (255) whereupon conditioned air (256) flowing into the channel (255) moves along, over and past the beard (102), causing the free ends (119) of the fibers to enter the flow channel (255) and become aligned generally along the length of the flow channel (255). Continued flow of conditioned air (256) into and through the flow channel (255), hence in a direction generally parallel to the length of the fibers which make up the beard, ultra-rapidly conditions only the fibers in the beard (102). Air flow rates may reach hundreds or even thousands of ft/sec velocity within the flow channel (255) and conditioning of the fibers may be accomplished within a matter of seconds. Withdrawal of the beard (102) from the flow channel (255) is sensed as a part of length testing of the fibers of the beard. Other test modules may be employed.
