Abstract
A fanner magnet assembly including a power actuated carriage and a magnet assembly mounted on the carriage for lost motion relative to the carriage and for pivotal movement relative to the carriage. The magnet assembly is moved forwardly into engagement with a side face of the associated stack of metal sheets, whereafter the forward movement of the carriage is continued as allowed by the lost motion connection between the magnet assembly and the carriage to a predetermined initial position, whereafter proximity switches function to withdraw the carriage relative to the magnet assembly to an operative position in which the desired amount of side loading is applied to the stack. As misaligned sheets are encountered in the stack as the stack is moved incrementally upwardly, a beveled face at the bottom of the magnet is cammed rearwardly to accommodate the misaligned sheets or, in the event of grossly misaligned sheets, the misaligned sheets engage the undersurface of the magnet and pivot the magnet assembly upwardly to generate a signal to totally withdraw the magnet assembly from the side face of the stack whereafter the assembly is again advanced to establish the desired loading against the side face of the stack.
