Abstract

PURPOSE: To lessen the width of the tapered surface at the edge of a magnetic tape which was cut and establish a fine workmanship of the cut face of the edge by forming a gap with the side circumferential surface of a columnar cutting blade made in a small diameter for occluding a circular disc blade with the columnar blade and making the width of the produced gap 1.5-5 times as large as the thickness of the circular disc blade. CONSTITUTION: A gap 10 is formed while the side circumferential surface of a columnar cutting blade 8 is made a small diameter 9 for occluding a circular disc blade 5 with the columnar blade 8, and the width L of the formed gap 10 is made 1.5-5 times as large as the thickness of the circular disc blade 5. As a result, a web 11 of magnetic tape transported is cut in this gap 10 having a very small width, so that it is possible that the tape web 11 is prevented from being drawn into the gap 10 together with the circular disc blade 5 and cut by the occluding part of the two blades 5 and 8 in a good performance. Accordingly the tape web 11 can be cut in a width approximately equal to the length of the columnar blade 8 in good workmanship, and a high quality magnetic tape with excellent electromagnetic conversion characteristic can be yielded in which a fine workmanship of the cut face of the edge is ensured.
