A method and apparatus for removing optic fibers from multiple spools of optic fiber involving one or more rotating trees on which spools of optic fiber are seated, a transport passage and a rotating carousel. The free end of a fiber is pulled through the passage and attached to the rotating carousel such that the rotation of the carousel removes the rest of the fiber from the spool(s). The passage can be equipped with one or more rollers to reduce the friction between the fibers and the passage. The carousel may feature retractable rails to facilitate removing the fibers. The passage may also feature a blower and/or a venturi that provides suction to facilitate the movement of one or more fibers through the passage. A reciprocating tracking unit can be used to spread the fibers onto the carousel.

An apparatus and method for removing sheet or web material from a roll employs an at least partially hollow cutting tube that rotates against a cull roll. The cutting tube has a slot along some of the length of the tube and carries a blade that is extendable from the slot. As the slot positions against the cull roll, the blade is extended and translated along the length of the slot to cut the material away from the roll.

An unlaid slabbing apparatus capable of profiling a roll of tissue material by determining the diameter, circumference, and weight of the roll. The slabbing apparatus calculates the amount of material to be removed based on operator input and predetermined parameters of weight, diameter, and density.

A production method for a separated fiber bundle includes at least: [A] a partial separation step for obtaining a partially separated fiber bundle in which separation-processed parts, each separated into a plurality of bundles, and not-separation-processed parts are alternately formed along the lengthwise direction of a fiber bundle comprising a plurality of single fibers; and [B] a cutting step for cutting the not-separation-processed parts of the partially separated fiber bundle formed in the step [A] along the lengthwise direction of the fiber bundle. A separated fiber bundle produced by the method, a fiber-reinforced resin molding material that uses the separated fiber bundle, and a production method for the fiber-reinforced resin molding material.
