A segment pickup apparatus for handling material segments. The apparatus includes a frame and at least one pair of picker assemblies coupled to the frame. Each of the picker assemblies includes a linear array of carding elements, and each of the carding elements is resiliently coupled to one of the picker assemblies and is positionable relative to the frame in a resting position and in a picking position. Each of the carding elements includes a base portion and a linear array of substantially parallel, elongated, resilient needle-like elements extending from the base portion to a distal tip. When a carding elements is positioned in the resting position, the distal tips of that carding element lie above a picking plane, and when a carding elements is positioned in the picking position, the distal tips of that carding element lie substantially in the picking plane. The picker assemblies are disposed such that the carding elements are arranged in pairs, and in each pair the needle-like elements of one carding element slant towards a first direction and the needle-like elements of the other carding element slant towards a second direction. The segment pickup apparatus further includes a carding actuator device for positioning pairs of carding elements in the resting position and in the picking position, and also includes a picker actuator device for displacing the picker assemblies relative to the frame in the first direction and in the second direction.
