To trim a molding (14) of a material which is organic or a non-metal mineral, where the molded object has at least one flash line (B1) from the molding action, a straight metal wire (28) is used to scrape the flash line. The wire (28) is smooth and tensed, and is applied to the flash line (B1) and across it, to move along the line at a tangent to the surface of the molded object (14). The flash line (B1) is on a plane, and pref. a plane of the symmetry of the molding. The molded object (14) has a grip handle (20) with two flash lines (B1) on the same plane at the outer and inner surfaces of the handle (20). At the start of the flash line scraping action, the molding has a residual moisture level of 14-18% of the dry weight. An Independent claim is included for an appts. with a base (22) to carry a bow (24) to support the tensed scraping wire (28). Preferred Features: The base (22) can carry two bows (24) with tensed scraping wires (28), to trim the flash lines (B1) at the outer and inner surfaces of the grip handle (20). The base (22) rotates on a support (32) to give a selective action by the scraping wires (28). The base (22) is rotated on the support (32) by a rotary piston (34), pref. operated by compressed air. A further Independent claim is included for a robot with a rotating wrist (16) fitted with a tool (12), structured with the scraping wire assembly. Preferred Features: The scraping wire (28) is aligned along the axis (X) of the rotation of the wrist (16). |
