  • Patent number: 4056961
    Abstract: Apparatus for forming cylindrical spacers from metal blanks includes a base plate mountable upon a support with a series of spaced uprights upon the base plate. A die bar spans and is secured to said uprights. A bending roll shaft is arranged parallel to and spaced from said die bar and is rotatively journalled upon said uprights. The roll shaft has an elongated slot adapted to supportably receive the edge of one or more blanks to be formed. A rotative drive is connected to said roll shaft whereby said blank is guidably interposed between the roll shaft and die bar and adapted to wrap around the roll shaft during rotation thereof. Provision is made for stripping the formed spacers from the roll shaft. The method of forming cylindrical spacers from flat metal blanks comprises the steps of rotatively mounting a slotted bending roll shaft upon a horizontal axis and assembling and interlocking the lower edge of one or more blanks down into the roll bar slot.
