Abstract: Comb section pair of an articulating expansion comb for processing textile threads or filamentary wires, including a first and a second comb section pivotally joined together at an axis of rotation in the vicinity of an end of each comb section, a group of comb needles disposed on each comb section in a respective alignment plane, each of the comb needles being mutually spaced apart by a given comb needle division, the alignment planes intersecting at the axis of rotation, the axis of rotation extending exclusively through the comb needle group of the first comb section, a last comb needle of the comb needle group on the first comb section being disposed at least one comb needle division beyond the axis of rotation toward the end of the first comb section, a first comb needle disposed closest to the end of the second comb section being at most one comb needle division farther from the axis of rotation than the last comb needle of the first comb section.
