Abstract
A cutting tool for a cable jacket having a circular blade for location on one side of the cable and two rollers for engagement on the other. The blade or the rollers are inclined to cause the blade to engage the jacket at an inclined angle to the longitudinal direction of the cable. This inclined cable causes the tool to move helically around the cable when the tool is rotated thereby providing a helical cut into the jacket.
Claims4
A cutting tool for cutting around the periphery of a cylindrical article comprising a circular blade and two laterally spaced rotatable article engaging rollers, the blade rotatable about an axis and having a peripheral cutting edge, and the two rollers mounted about rotational axes in positions spaced from the blade with a progressively changing part of the peripheral surface of each roller opposing the cutting edge of the blade, as the rollers are rotated, to enable the cylindrical article to be positioned between and in rolling contact with the rollers and with the cutting blade, said peripheral surface part of each roller being inclined towards the rotational axis of the blade in a direction from end-to-end of the roller and with the direction of inclination of said peripheral surface part of one roller being opposite to that of the other roller such as to cause the tool to hold the cylindrical article with the blade lying at a bias angle to the longitudinal direction of the article.
