Abstract

Apparatus for stacking and intermittently discharging stacks of sheet material for electrical machines and the like. A plurality of mandrels are provided which are successively movable into a position for forming stacks of sheets continually supplied by a horizontal conveyor. A turntable is provided for moving the mandrels into and out of respective sheet receiving positions. In order to accommodate intermediate stacking of the sheets while mandrels are being exchanged, a mandrel tip is provided which is positionable in alignment with the mandrels when in a sheet receiving position. During normal stacking operations, the mandrel tip is supported at the respective mandrel. During exchange of mandrels clamping jaws hold the mandrel tip in position and a slide member is moved into a position so as to hold an intermediate stack of sheets on the mandrel tip. Once a new empty mandrel has been placed in position under the mandrel tip, the holding jaws and the slide means are moved so as to permit the intermediate stack to fall onto the mandrel to start another stack of sheets.
