Abstract

An adjustable cable slitting tool for longitudinally slitting optical fiber buffer tubes and other precision cables includes a T-shaped body and a guide that slides relative to the body to hold and guide the cable to be slit in a guide channel. A slitting blade is mounted on a blade carriage that can be precisely adjusted with an adjustment screw to control the depth the slitting blade projects into the guide channel. A scale and indicator marks allow the desired depth of cut to be adjusted with precision by comparing indicator marks on the adjustment screw with the scale and other indicator marks on the tool body. The adjustment screw has a tapered portion that drives the blade carriage through a single contact point via a ball bearing. A deformable pad material in contact with a threaded portion of the adjustment screw acts as both a friction adjustment and part of the backlash prevention mechanism. The backlash prevention mechanism includes several elements that cooperate to substantially completely eliminate objectionable backlash.
