摘要

Improvements in the manufacture of caps for chains with recesses at the ends, characterized by comprising a phase of preparation of the strip by longitudinal rolling in order to determine lateral areas of lower height than the central area that separates them, constituting lateral steps in the profile whose lower base is flat, proceeding to the cross section of the strip and the curved and subsequent rolling thereof to adopt a cylindrical structure in which both ends of the strip coincide butt, constituting a cap of general cylindrical structure endowed with recessed lower areas of lesser diameter than the central part and whose inner surface adopts uniform cylindrical shape.
