Patent ID: 8753178

Claim:
A scoring machine for scoring a surface of an item which is substantially plane in its main dimension and is curved transversely to its main dimension, the item being moved along a transport path in a direction of movement, such as a surface of an item being conveyed forwards by a number of conveyors, wherein the scoring machine comprises a structure with a curved path adapted to have substantially the same curvature as the conveyed item transversely to its main dimension, and a number of scoring devices being mounted on the structure in such a manner that the scoring devices are movable along the curved path extending transversely to both the transport path and the direction of movement of the item moved, wherein the structure comprises a tubular bearing having an internal tubular bearing part with a curved path and an external tubular bearing part, the scoring device being mounted on the external tubular bearing part in such a manner that the scoring device can rotate about the centre line of the tubular bearing parts and transversely to the direction of movement of the item moved by a drive mechanism.
