<p>Composed (1) of a support built in iron or other materials, (2) central axis having several bearings, depending on the number of bars and rectangular pieces where the bearings are, (5) bars and their respective hammers with rubber wheel. There are several materials that are used in this construction, depending on the size of the machine and the necessary resistance. The furrow and its respective cylinders is a fundamental piece of this machine because besides reusing the beat, it transports and changes the force received at the cylinders in relation to its axis, all of them forming an interesting set of force (5) that produces and does not absorb.</p> |
