ABSTRACT:
A machine for assembling blower rotors comprises a fixture with a cylindrical interior surface in which there are shallow, axially spaced, radially inwardly opening circumferential grooves. The grooves receive marginal portions of flat sheet metal discs that have blade slots opening to their peripheries, thus holding the discs in spaced, coaxial relationship and allowing them to be indexingly rotated, ratchet-fashion, by pawls that engage circumferentially facing edges on the discs. Indexing rotation brings a slot in each disc into alignment with a blade guiding surface on the fixture, and a pusher moving along that surface forces individual blades edgewise along it and into the discs.
