Abstract: A mount (9) is disclosed for mounting an ink jet printhead (11) in position to imprint indicia on a surface (7) of an object (5) conveyed along a path (3) past the printhead. The mount comprises a support (21) and a slide (53) carried by the support. The slide has a slide body (55) connected to the support, a slide member (57) movable relative to the slide body along a slide axis (SA) between an extended position (as shown in FIG. 1) and a retracted position (not shown), and device for resiliently biasing the slide member relative to the slide body toward its extended position. Mounting plate (43) is provided for carrying the slide relative to the support such that the slide axis (SA) may be adjusted relative to the support so as to position the slide axis so as to either be perpendicular to the direction of movement of the object conveyed along the path or to be angled (as shown in FIG. 3) toward the object approaching the printhead at an oblique angle.

Abstract: A brake lathe includes a set of rotor cutting bits and a drum cutting bit. Each bit has associated therewith an encoder for measuring the displacement of the bit. The displacements as measured by the encoder are used by a controller to digitally determine various parameters such as absolute thickness of a rotor being lathed, the depth of cut into the rotor, absolute internal diameter of a drum being lathed, and the depth of cut into the drum. The lathe includes a display for displaying the values of the parameters. The lathe includes a calibration mode for calibration of either the rotor cutting or the drum cutting function of the lathe as desired.
