ABSTRACT:
An apparatus for forming sheet material assemblages includes a plurality of pockets which are movable past a plurality of sheet material feeders. Each of the pockets includes a sheet material support which is movable between any one of a plurality of closed positions and an open condition. When the sheet material support is in a closed position, it blocks the lower end portion of the pocket and supports sheet material in the pocket. When the sheet material support is in the open condition, it is ineffective to block the lower portion of the pocket so that the sheet material assemblage can move out of the pocket through the lower end portion of the pocket. An actuator is provided to move the sheet material support from the open condition to a closed position. The sheet material support is connected with side portions of the pocket by a four bar linkage. A clutch assembly in the four bar linkage is operable from an engaged condition to a disengaged condition to release the sheet material support for movement from a closed position.
