PROBLEM TO BE SOLVED: To provide a cross cutting device for making a cutout (34) from a flat material web (30) moved in a conveyance direction (T), and an operation method corresponding to the cutter. SOLUTION: The cutter has two cross cutting units (10 and 20) each having a fixed blade (12) and a rotary blade (16) provided on a rotary element (14), and the units (10 and 20) are placed at a distance from each other in the conveyance direction (T). A second rotary element (24) can be coupled to a sucking device so that the cutout (34) is at least temporarily fixed onto the second rotary element (24) when in use. With the invention, the rotary element (24) has a plurality of zones (60, 62 and 64) along its circumferential surface, and sucked air can serve individually or in combination for the plurality of zones to fix the cutout (34) in various formats.

PROBLEM TO BE SOLVED: To adequately removing dusts generated in a process of cutting a protective tape of a semiconductor wafer by cutting off along the wafer contour the protective tape attached on the surface of the semiconductor wafer in a method for cutting protective tape of the semiconductor wafer. SOLUTION: While relatively moving a cutter blade 12 along the outer periphery of a semiconductor wafer W, dusts generated at the tape cutting portion by the cutter blade 12 and adhered on the upper surface of the protective tape T are swept and collected by a dust collecting member 56 to be moved relatively to the semiconductor wafer W together with the cutter blade 12. After finishing the tape cutting operation, the dusts swept and collected at a predetermined position are vacuumed and removed with a suction nozzle 61. COPYRIGHT: (C)2009,JPO&INPIT
