Cam mechanisms based on a double roller translating follower of negative radius

Mechanism and Machine Theory, 2016
Abstract Constant-breadth cam mechanisms are characterized by the fact that the closure of the cam-follower contact is guaranteed thanks to the geometry and, therefore, auxiliary elements as springs are not necessary. On the other hand, cam mechanisms with a negative radius roller follower allow designing simple machines exerting remarkably high ...

Development of a rapid solidification process with a double-roller method

Materials Science and Engineering, 1988
Abstract A thin strip caster has been developed which consists of twin cooling rollers, a secondary cooling zone, tension control systems and a continuous-coiling machine. With this caster, fine crystalline strips were continuously produced to a near-net shape whose dimensions were 0.2–1 mm in thickness, 250–500 mm in width and 500 kg in unit coil ...
