摘要

A method and apparatus for chopping long unwound items like fiber, fiber strands, yarn, etc. having an idler roll (20) for pressing the item(s) against a backup roll (4) for pulling the item(s) into the chopper uses an improved mount (22) for the idler roll (20) that maintains the outer peripheral surface of the idler roll into more consistent contact with more consistent force with the item(s) being chopped. The idler roll mount assembly (22) comprises a yoke (23), a connector (26) and a means (31) for applying a force to the connector (26) attached to the yoke (23) for biasing the idler roll (20) against the material to be chopped.
