The apparatus comprises a crank arm in a crank-arm press with a curved tool at the end of the crank arm being constrained to move so the curved tool makes rolling contact across a flat, stationary substrate. The crankshaft rotates about an axis, the crank arm is rotatably mounted at one end to the crankshaft, a curved tool is mounted at the other end of the crank arm, a line on the surface of the curved tool and parallel to the crankshaft axis of rotation is constrained to move perpendicular to a plane while the curved tool is in rolling contact with the substrate, said plane being the plane of the flat stationary substrate, the radius of curvature of the curved tool being greater than the length of the crank arm; and with the radius of the curved tool, the length of the crank arm, and the eccentric radius of rotation of the crankshaft being selected to maintain the contact line of the curved tool in the substrate plane during the rolling contact.
An apparatus for eccentrically moving a curved die in an arcuate motion in a workplace across a substrate to place an item on a film onto said substrate comprising a moving mechanism including an eccentric moving axis and a crank arm for moving said die in an eccentric motion around said eccentric axis to stamp said item onto said substrate with a rolling motion.
An apparatus to provide a rolling motion of a curved tool along a substrate supported on a flat anvil comprising, a crankshaft, a crank-arm with at least one curved cylindrical tool having a radius of curvature greater than the length of the crank-arm at an extremity of said crank-arm with the axis of curvature of said tool or tools parallel to the axis of rotation of said crankshaft and an integral mechanism to restrict a line coincident with a fixed point on the curved surface or surfaces of said curved cylindrical tool or tools and parallel to all said axes to move in a plane parallel to a plane intersecting said crankshaft axis of rotation and perpendicular to said flat anvil during at least a portion of said crankshaft rotation.
