Abstract: A method is described in which a length of hot rolled product is decelerated in the course of being passed through the rotating curved guide of a coiler. The product exits the coiler at a reduced velocity and is delivered to and progressively accumulated on a cylindrical drum as a helical formation of rings. The drum is rotated to continuously unwind the accumulating product at the reduced velocity. The tail end of the product is retained in the coiler until substantially all of the rings previously deposited on the drum have been unwound.

Abstract: A programmable machine for roll forming metal decoiled from a roll of metal and cutting the panels at a desired angle is provided.

Abstract: Threads are formed in situ throughout a bore of a sleeve inserted into a corresponding hole a substrate. A sleeve having a bore is inserted into a corresponding hole of a substrate. A mandrel is rotated through the sleeve. The mandrel has a threaded ended; the threaded end rotating throughout the bore of the sleeve forms threads throughout the bore. Prior to inserting the sleeve into the corresponding hole of the substrate, the sleeve can be placed onto the mandrel. In this case, the mandrel has an increasing diameter at the threaded end thereof, such that the sleeve rests on the mandrel towards the threaded end thereof where the bore has a smaller diameter than the mandrel. The mandrel is then rotated out of the sleeve in a direction opposite the direction in which the sleeve has been inserted into the corresponding hole of the substrate.
