Claims12
A fiber sample conditioning system, comprising:
- a comb for engaging and retaining fibers to form a beard, and
- at least two rotating brushes for brushing the fibers simultaneously from opposite sides of the beard in a direction along the fibers away from the comb.
A fiber sample testing system, comprising:
- a drum for presenting fiber tufts protruding through a peripheral wall of the drum,
- a first translator for moving a comb toward the drum,
- the comb for engaging and retaining fibers from the fiber tufts to form a beard,
- the first translator for moving the comb away from the drum,
- a second translator for simultaneously moving at least two rotating brushes toward the beard from opposite sides of the beard,
- the brushes for brushing the beard in a direction along the fibers away from the comb,
- the first translator for moving the beard out from between the brushes,
- a third translator for moving the comb to a testing station,
- the first translator for moving the beard into the testing station, and
- the testing station for testing the fibers in the beard.
7 more elements
A method of conditioning fibers, the method comprising the steps of:
- forming a beard of the fibers within a test plane,
- bringing at least two opposing and rotating brushes into the test plane from opposite sides of the test plane and against the beard, and
- brushing the beard along the test plane between the at least two opposing brushes to substantially singulate and linearize the fibers of the beard.
