Abstract

The sheet iron is fed from a roll (1) and is conveyed by drive rollers (3) onto the feed for cold rolling by the main rollers (4). The feed table has several linear induction motors (7) above and below the pairs of plates (9, 10) creating a magnetic field between the plates (9, 10). the motor cores have their centrelines converging towards the feed table end to ensure stability of the sheet fed through. The motors have three basic functions to guide the leading edge of the sheet to the correct location, to control the sheet during the feed period and to control the free trailing edge of the sheet at the end of the roll. the motors are adjusted vertically by the hydraulic jacks (8).
