PROCESS AND APPARATUS FOR PREFORMING A SUBSTANTIALLY FLAT BLANK OF AN OPEN CLAMP.

摘要

A method and a machine for preforming a substantially flat blank of an open clamp designed to be mechanically assembled, near its free ends, into a circular clamp having a configuration at least about equal to that of the clamp when it is installed on an object to be secured on a relatively fixed and generally circular part, the free ends of the clamp being spaced a short distance in the axial direction.
