ABSTRACT:
This invention relates to a novel method of making pulleys and pulley blanks from sheet metal. The sheet metal is stamped into pulley blanks having an upstanding cylindrical wall, the cylindrical wall is then thickened by being partially collapsed axially, followed by contacting with a roller. The roller can have a plurality of v-shaped grooves on its surface, to form a pulley for use with a poly-v belt.
