ABSTRACT:
An apparatus for penetrating a sheet material web being carried on a fabric. The apparatus including a penetrating device and an air flow that separates a portion of the sheet material web from the fabric adjacent the penetrating device so as to bring the web into contact with the penetrating device. In one embodiment, a vacuum lifts a portion of the sheet material web into contact with a slitting member such that it continuously slits the sheet material web longitudinally along its length as the fabric carries the sheet material web beneath it. In an alternative embodiment, a pressurized air stream is directed to a bottom portion of the sheet material web so as to separate the web from the fabric. A method for penetrating a sheet material web as it is carried on a fabric includes the steps of carrying the sheet material web on a fabric in a longitudinal direction, applying an air flow to the web so as to separate a portion of the web from the fabric, penetrating the web as it is separated from the fabric and reapplying the sheet material web to the fabric.
