Abstract
The provided process creates a stamped tubular form with integral bracket by feeding a metal strip with a first thickness into a stamping tool containing a plurality of stations. Material is removed from the metal strip, leaving behind a tubular blank with an integral bracket. The tubular blank is formed by a forming station into a U-shaped form containing walls. The walls are closed in a closure station into a tubular shape wherein the edges of the walls are abutted and compressed, forming a tubular form which increases the metal thickness. This invention includes products formed by this process.
