Abstract

PURPOSE: To facilitate manufacture of vanes different in performance and characteristic by forming a runner for multiple vane blower with louvered vanes arranged longer in length than a pitch between vanes en bloc through drawing one sheet of material.
CONSTITUTION: A waveform cylinder 4 with a constant pitch P1 on the circumference, a side well surface 6 of the waveform cylinder having a bearing boss fitting hole 5 on one end and a reverse U-shaped end 7 facing outside on the other end are formed en bloc through drawing a proper diameter of metallic sheet on a special drawing machine; then a vane 8 is formed by louvering a portion of the waveform cylinder 4 which is long correspondingly to the pitch P1 of the waveform zone in semicircular arc shape inside the waveform cylinder so that it is longer than the pitch P1 with a suitable width of waveform zone 4a left on both ends of the waveform cylinder. For longth l1 of the vane 8, an arbitrary vane interval is obtainable from varying R dimension in which to form the waveform zone 4.
