<p>Apparatus for Manufacturing Annular Piles of Magnetic Plates for Electrical Machines An apparatus for manufacturing piles of magnetic plates of annular shape from stamped sheet metal segments having slots open toward the inside and formed by radially directed arms having enlarged inner ends comprises six operating stations namely a first station in which sheet metal segmented are fed from magazines to build up a stack of plates in which successive layers of segments are angularly staggered, a second station at which the height of a partially formed stack of segments is measured, third and fourth stations for feeding additional thinner segments or thicker segments to the stack according to the measurement in order to obtain a stack of predetermined thickness, a fifth station at which the segments are centered and fitted with rivets and a sixth station at which the stack of segments is compressed and the rivets are set.</p> |
