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.

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.

A bobbin stripping unit for removing yarn residues from a bobbin, the bobbin being substantially cylindrical with a longitudinal axis. The bobbin stripping unit includes a holding device which holds the bobbin in a substantially vertical or horizontal position with respect to its longitudinal axis, at least one suction nozzle extending over substantially the entire length of the bobbin for sucking in yarn residues, and a casing which can be transferred between a stripping configuration and a release configuration. In the stripping configuration, the casing substantially surrounds the bobbin, at least partially. In the release position, the casing exposes the bobbin for insertion and removal.

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.
