Abstract

The non-cutting process forms metal lid rings with open interior and annular shaped edges. A cylindrical blank (10), e.g. a cylinder segment separated from the body of a can, is deformed by the concentric assembly of several annular tool segments (1-7), working axially downwards (v0) from 1 to 7. It is then deformed by an annular diverting lip (5a) of a tool segment (5) further inwards of the tool segment combination, in the radial direction (v0'). An upper tool segment (2) is held above the diverting lip to define a clearance (S) into which the blank is deformed radially inwards.
