Means and method for reducing the perimeter of a hollow thin walled member |
摘要 |
The wall of a thin walled hollow member such as the ferrule portion of an electrical terminal or the like is subjected to a longitudinal pinching force which may be applied by one or more pair of spaced parallel elongate forming surfaces at selective locations along the length of the perimeter of the thin walled member to produce one or more obliquely angled double thickness fins which are then subjected to an inwardly directed radial force causing the fins to be folded back against the outer surface of the hollow member which is thus tightly contracted about a further member located within the hollow member.
