    摘要： An apparatus for forming a line of separation in a plastic work surface includes a tool having a tool holder of thermally conductive material, an electric heating element and a tool member having a separating point. The holder is surrounded by an insulating member and includes a sleeve portion in which the tool member is releasably secured, the tool member projecting from the body in freely exposed manner with the separating point remote from the holder whereby the work surface may be engaged solely by the separating point which comprises a tip from which a surrounding surface extends in divergent manner. The holder is arranged to conduct heat from the heating element to the tip and suitable control means are provided for regulating the heating element temperature to a desired value. The apparatus is adapted to traverse the tool in orthogonal directions across a work-support surface in a head movably mounted above the surface, the tool being releasably mounted in a clamping arm of a pivotable lever having an actuating arm, actuating means engaging the actuator arm to bring the separating point of the tool into and out of engagement with the work on work-supporting surface by pivotal movement of the lever.Since the separating point is freely exposed the depth of penetration into the work is not effected adversely by surface irregularities or cutting swarf on the work but is determined by the point form, temperature rate of movement and pressure on the work.
