Abstract

The slitter is for trimming the edges of magnetic tape or strip material 10 to obtain superior edge quality and straightness. The slitter includes stationary drum 11 of large diameter. Long tape guides 12 and 13 are fixed to drum 11 on both the inlet and outlet sides of slitting blades 14. Guide 12 extends over about 120' of the drum 11 circumference. Guide 13 extends over nearly 180 degrees of the drum 11 circumference. Tape 10 is drawn from reel 15 to reel 16 around drum 11 under tension. Guides 12 and 13 maintain tape 10 in alignment since the tape is given lateral stiffness by its curvature around drum 11. Considerable lateral clearance is provided between guides 12, but a very minimal lateral clearance between guides 13 is held. Thus, both lateral shift and skew are prevented.

Tape or Strip Slitter

The slitter is for trimming the edges of magnetic tape or strip material 10 to obtain superior edge quality and straightness. The slitter includes stationary drum 11 of large diameter. Long tape guides 12 and 13 are fixed to drum 11 on both the inlet and outlet sides of slitting blades 14. Guide 12 extends over about 120' of the drum 11 circumference. Guide 13 extends over nearly 180 degrees of the drum 11 circumference. Tape 10 is drawn from reel 15 to reel 16 around drum 11 under tension. Guides 12 and 13 maintain tape 10 in alignment since the tape is given lateral stiffness by its curvature around drum 11. Considerable lateral clearance is provided between guides 12, but a very minimal lateral clearance between guides 13 is held. Thus, both lateral shift and skew are prevented. Slitting blades 14 can be of a jewel material to reduce wear.
