Abstract
A fiber opening device comprising a feed section opening into the fiber opening section. The opening section includes a cabinet with an inner chamber, a waste removal chamber and a fiber web removal unit. The inner chamber includes a doffing roll and a contaminant collecting area located above first and second opening rolls. A main roll is located beneath and between the opening rolls and a waste removal section and a fiber web removal section are located beneath the main roll. In operation, fibers delivered into the inner chamber are first acted on by primarily one of the opening rolls which creates a tumbling action in which contaminants are dislodged and deposited into the contaminant receiving area while other fibers are picked up by the second opening roll carried to and doffed onto the main roll forming a fiber web for delivery to the fiber web removal section.
