摘要

Process for manufacturing seamless housings for dynamos, starter motors and the like, characterized essentially by obtaining them coming out of the metal sheets cut and bent in the characteristic that the welding and picking operation are substitutable by a linking operation in the extremities of the sheet, in one of which at least two projections of special profile and one or more guide teeth have been made and in the second end the corresponding parts to said guide projections have been made and that to the unión and link of the extremities so profiled, the casing is subjected to an axial pressing, in order to increase the mechanical strength and reduce the magnetic losses caused by possible between irons of the encale itself.
