ABSTRACT:
A method for segregating and transferring a product from a web of material includes the steps of conveying the web of material between a punching roll and a counter pressure roll, the punching roll having at least one cutting edge and at least one suction orifice; punching-out the product from the web with the cutting edge; adhering the punched-out product on the punching roll under a vacuum connected to the at least one suction orifice; rotating the punching roll to position the punched-out product proximate to a conveyor belt; detaching the punched-out product from the punching roll; and transferring the punched-out product onto the conveyor belt. In certain embodiments, the suction orifice of the punching roll is ventilated with a gas stream to facilitate detachment of the punched-out product; and a vacuum is applied to the conveyor belt to draw the detached product thereto and hold it thereon under suction.
