Diaper folding apparatus

Apparatus for folding disposable diapers comprising a frame, means operably associated with said frame for advancing unfolded disposable diapers along a predetermined path whereby each diaper has leading and trailing edge portions.

• a drum mounted on said frame in the path of diaper advancement, said frame being equipped with means for rotating said drum about its axis and with further means for applying suction to circumferentially spaced apart areas of the periphery of said drum for holding said leading and trailing edge portions of the diaper against the drum, said drum having an opening in the periphery thereof between said circumferentially spaced apart areas and confronting the portion of said diaper between said leading and trailing edge portions,
• a tucker mounted in said drum for rapid projection from said drum against said diaper confronting portion to develop a transverse outfold in said diaper,
• a pair of wheels rotatably mounted in side-by-side spaced relation on said frame adjacent said drum in axially aligned relation thereto and positioned adjacent a point in said path where said tucker projects from said drum whereby said tucker is adapted to project said diaper confronting portion between said wheels for takeaway from said drum,
• a pair of aligned, spaced apart generally planar folding plates mounted on said frame extending generally radially of said drum and positioned along a plane passing between said wheels so as to also be positioned adjacent a point in said path where said tucker projects from said drum, the spacing of said plates permitting said tucker to project between said plates in developing said transverse outfold, said plates opposing the development of an outfold extending the full diaper width but instead forming an infold in each diaper aligned with the partially developed outfold and on each side thereof, each plate being equipped with an inwardly directed air jet, and
• a belt system for gripping a diaper to move the same generally radially away from said drum while said diaper infolds are passing over said plates.
