ABSTRACT:
Two embodiments of the invention are described, namely a machine for performing an adhesive-applying operation progressively along marginal portions of the bottoms of lasted shoes and a machine for performing a roughing operation progressively along side wall portions of lasted shoes, each machine comprising a tool holder (670) for supporting a tool (20) for operating along three axes (X-, Y- and Z-axes) upon a workpiece surface, e.g. marginal portions of a shoe bottom. In addition the tool holder (670) is capable of pivoting in two directions, widthwise and lengthwise of the shoe bottom, about a point (P), but without displacment of said point in relation to the shoe support by reason of such pivotal movement. The movement along the various axes and the pivotal movement are all controlled by n.c. motors, e.g. stepping motors ((84), (144), (122), 698, 700), and operator-actuatable means is provided for enabling the path of such tool, including such pivotal movement, to the digitized under operator control.
