Abstract: The staves for producing wooden barrels are assembled of individual segments which are fixedly connected to each other at end faces. The individual segments are shorter wood pieces that are assembled such that the stave has the required length. The wooden barrel is produced of such staves which are placed against each other seal-tightly with their narrow sides. The individual segments are machined at their end faces such that individual segments resting against each other after assembly are positioned at an angle relative to each other and form a raw stave that is curved across the length.

Abstract: A machine for conical machining workpieces of wood and plastics has a support supporting the workpieces during feeding in a transport direction through the machine. Rotatably driven tools are provided to machine longitudinal sides of the workpieces extending in the transport direction. At least one of the rotatably driven tools is adjustable transverse to the transport direction. A tongue and groove guide guides the workpieces through the machine in transport direction. In a method for conical machining workpieces, the workpieces prior to or during feeding are measured in regard to the conicity to be machined. A form-fit element is produced on the workpieces and interacts with a counter form-fit element during feeding of the workpieces so as to guide the workpieces in transport direction. At least one of the rotatably driven tools is adjusted transverse to the transport direction during feeding of the workpieces based on the measured conicity.
