Designed by Mr. G.H.Thomas, these Bending Rolls use the "Pinch Roller" principle where the metal to be rolled is securely gripped between a pair of rollers of Ø1 1/8" and positively driven forward against an adjustable deflecting roller. In comparison to conventional Pyramid designs, complete parallel-edged cylinders can be rolled without further manipulation.
The Workshop Bending Rolls will roll steel strip (cold rolled, close annealed) up to around 16 SWG (1/16") and non-ferrous sheet of up to around 14 SWG (0.080"). Grooves cut in the pinch rollers permit the rolling of angle and T sections. Maximum material width for the standard kit is 10".
Our kit includes the drawing set, construction notes, bronze & brass bearing material, all necessary steel section, fasteners and the 4 finished driving gears. A vertical milling machine would make light work of the co-ordinate drilling and milling of the 2 side plates, which are pinned together during manufacture to ensure parallel locations are made.
