(under subclass 523) Device including means to constrain a cutting tool to follow a path, with respect to the work, which is determined (at least in part) by a mutually engaging and relatively movable contoured guide or pattern and a follower associated with the tool positioning means, so that the tool follows a line of cut which is similar (in at least part of its extent) to the guiding surface of the guide or pattern or produces spaced cuts lying along such a similar line.
(1) Note. Search Class 33, subclasses 18.1+ and 501+ for the guide or pattern and the follower subcombinations.
