ABSTRACT:
A method is provided of forming a circular chuted axially extending mixer from an originally circular scalloped, radially extending ring blank. The method utilizes a common mechanical press with male and female die portions. The female portion is pressed down over the blank against the male portion to form a convolution in the blank, with progressively increasing height. Successive convolutions are formed which tends to gather together the radially outer portion of the blank thereby straightening its originally circular shape. Repeating this process forms a relatively straight band having convolutions forming chutes therebetween. Individual chuted bands can be joined together to form a single circular chuted axially extending mixer.
