Abstract
Automatic apparatus for assembling elongated, transversely curved blades in a fixture for holding the blades in a predetermined spaced relationship corresponding to the blade spacing in a centrifugal blower wheel. A first transfer assembly transfers individual blades from a die press to a conveyor and a second transfer assembly transfers individual blades from the conveyor to the fixture. Each blade is held in a fixed position on the first transfer assembly by suction and/or magnetic force, on the conveyor by magnetic force, on the second transfer assembly by magnetic and/or suction force, and in the fixture by a resilient clamping mechanism. A pushing device moves alternate blades axially relative to the remaining blades on the conveyor so that blades are loaded in the fixture with flanges at opposite ends of adjacent blades in a staggered relationship. The fixture includes a pair of coaxial pressure discs cooperating with resilient means on a pair of coaxial holding discs so as to clamp multiple blades in slots within the fixture. Provision is made for different numbers and sizes of blades and different fixture diameters.
