ABSTRACT:
A machine for machining workpieces of wood or plastic material has at least one longitudinal profiling unit with at least one longitudinal profiling spindle. At least one advancing unit is provided for moving a workpiece past the at least one longitudinal profiling unit. The advancing unit has upper clamping jaws arranged above the workpiece and lower clamping jaws arranged below the workpiece such that at least some of the upper clamping jaws are staggered relative to the lower clamping jaws, when viewed in a plan view onto the advancing unit. A small free space is provided between the upper and lower clamping jaws, when viewed in a plan view. During transfer between the machining processes, the workpieces remain clamped at all times so that precise machining is ensured.
