Abstract

The rolls are knocked out for changing by a power cylinder mounted on an axle on a table, so that it can be rotated through 180 degrees out of the pass line when the mill is operating. A double acting cylinder is used to apply a blow by a punch at the end of the piston to knock out the rolls.
