Device and method for forming a flanged ring

A method of making a flanged ring from a device including a first pair of opposed surfaces and a second pair of opposed surfaces, comprising the steps of:

• a) providing an elongated straight flange with an elongated base and an elongated protrusion extending from the elongated base;
• b) feeding the elongated straight flange with respect to the device such that the first pair of opposed surfaces compress the elongated protrusion to increase the length of the elongated protrusion, wherein the device further forms a first portion in the elongated protrusion and a second portion offset from the first portion in the elongated protrusion, and the second pair of opposed surfaces compress the elongated base to increase the length of one portion of the elongated base relative to another portion of the elongated base.

A device adapted to form a flanged ring including an elongated curved extension from an elongated straight flange with an elongated base and an elongated protrusion extending from the elongated base, the device comprising:

• a) a first wheel rotatable about a first rotational axis and a second wheel rotatable about a second rotational axis that is parallel to the first rotational axis, wherein corresponding outer peripheral surfaces of the first wheel and the second wheel form a first pair of opposed surfaces adapted to compress the elongated protrusion to increase a length of the elongated protrusion, the outer peripheral surfaces of the first and second wheel including knurled surfaces;
• and
• b) a second pair of opposed surfaces adapted to compress an elongated base of the flange to increase the length of one portion of the elongated base relative to another portion of the elongated base.
