Abstract

In accordance with the present invention, an apparatus is provided for cutting a workpiece moving in a predetermined path relative to a support. The apparatus includes a carriage and linear bearings for mounting the carriage to a support for movement relative to the support to follow movement of the workpiece as it moves in a predetermined path. A clamp is provided on the carriage for clamping the workpiece to the carriage, the clamp having an open position and a closed position. A scarf cutter movable between a first position and a second position is also provided on the carriage for making a scarf cut in the workpiece. A mechanism is provided between the scarf cutter and the clamp for moving the clamp from its open position to its closed position as an incident of the scarf cutter moving from its first position towards its second position, and, in one form of the invention, for moving the clamp from its closed position to its open position as an incident of the scarf cutter moving from its second position towards its first position.
