Rotary apparatus

A rotary cutting and forming apparatus for forming strip material for use in association with material forming dies comprising:

• a rotatable upper roll unit and a corresponding rotatable lower roll unit, said units being connected for synchronous rotation, each of said units comprising a corner member defining a central axis, said member having at least one recess extending along said member parallel to the central axis, said recess having bearing surface means of generally semi-circular shape, and at least one die support block, rotatably received within said recess, said block defining two ends and a platan surface to which at least one of said forming dies may be affixed;
• leading control pin means extending from a leading portion of a said end along a first axis;
• trailing control pin means extending from a trailing portion of a said end, along a second axis spaced from said first axis of said leading control pin means;
• said upper and lower roll units being spaced apart whereby said material may pass therebetween for formation by said dies;
• leading cam surface means positioned to engage said leading pin means, and having a predetermined leading cam profile;
• trailing cam surface means positioned to avoid said leading pin means, and to engage only said trailing pin means, and having a predetermined trailing cam profile different from said leading cam profile, whereby to support said die support blocks during a portion of the rotary cycle whereby a die affixed to said block on said lower unit may register with each other and cooperate together for the deformation of the material;
• and,
• bearing means for supporting said units.
