Abstract:
The invention relates to a method of rolling tire rim blanks from flat metal strips obtained by unwinding strip material from a coil which is cut into strips of desired lengths which are then rolled into a circular shape by anvil rolls cooperating with bodily moveable bending rolls producing a controlled flat portion on the leading end of the strip prior to rolling and another controlled flat portion on the trailing end of the strip following the rolling.
