After cutting, the backer is removed from the tow and the tow placed on the tool. The backer is then used to drive the following tows individually as directed by the controller. Finally, the backers are delivered to individual backer cassettes for disposal.

Abstract: A masking film adhering method and apparatus for transporting smoothly and accurately a masking film tape to which a wafer is stuck to the cutting location where the masking film is to be cut. The wafer is stuck onto the masking film tape by passing the masking film tape and the wafer through upper and lower adhesive rollers. The separation of the masking film tape is then increased from a cutting table so that the masking film tape having the wafer stuck thereon may not become adhered to the cutting table, by moving the upper adhesive roller upwardly when the wafer completely passes through the adhesive roller. After the masking film is transported to a cutting location, maintaining a predetermined distance between the masking film and the cutting table, the masking film tape is cut along the shape of the wafer. Sagging of the masking film due to the weight of the wafer is prevented to avoid the masking film tape adhesion to the cutting table.

Abstract: A method and apparatus for stretching an elastic member in cross machine direction and combining the elastic member, while held in tension, with a moving substrate web. A web of unstretched material, having elasticity across the direction of metering, is fed onto a first rotating drum at a speed slower than the surface speed of the drum.
