Tube having a flared end
First Claim
1. A method of flaring an end portion (14) of a deformable tube (16), including an annular tube wall, the end portion (14) having an annular burr (18) of lesser thickness than the tube wall extending into the tube (16), said method comprising the steps of:
- flaring the end portion (14) of the tube (16) and cold forming at least a portion of the end portion (14) into the inner surface of the flared end portion (14) by engaging the burr with a flaring tool to form a flared end portion (14) having a substantially uniform wall thickness and to round off the edge of the flared end portion (14).

Abstract
An apparatus (10) for flaring an end portion (14) of a deformable tube (16), the end portion (14) having an annular burr (18) extending into the tube (16), the apparatus including a conical projection (20) for flaring the end portion (14) of the tube (16) when the tube (16) is forced thereon and characterized by the conical projection being of a predetermined radius and having a predetermined slope for engaging the burr (18) as the end portion (14) of the tube (16) is forced onto the conical projection (20) to force the burr (18) into the inner surface of the flared end portion (14). A method of flaring the end portion (14) is provided and includes the steps of flaring the end portion (14) and forcing the burr (18) into the inner surface of the flared end portion (14) to form a flared end portion (14) having a rounded edge and a substantially uniform wall thickness.
