A product wrapping and discharge apparatus for receiving and wrapping a product such as an ice cream sandwich delivered by a machine of the type which includes a conveyor for carrying the ice cream sandwich to a wrapping station where a wrapper is disposed above the sandwich; an elevator which moves the sandwich upwardly through a wrapping mechanism which folds the wrapper downwardly over the front and rear sides and ends of the sandwich; a pair of end fold tuckers operative to provide end folds; a rear fold paddle operative to provide a rear fold; and a pusher operative to move the sandwich off the elevator and at the same time provide a front fold. The various actuating arms and linkages for the end fold tuckers, rear fold paddle and pusher are mounted just above the wrapping mechanism, thereby minimizing the number and length of actuating arms and linkages required, and consequently achieving a relatively high sandwich wrapping rate. The shape of the end fold tucker cams, and the configuration of the end fold tuckers and elevator, enable the tuckers to more easily and smoothly pass beneath the sandwich during the end fold tucking operation. The reduced vibration greatly increases the speed of the end fold tucking operation.
