Cutting machine

A cutting machine comprising first (10) and second (12) work piece support means, said means including opposed surfaces operable to grip a work piece (20) and move it in a controlled manner in a first direction, and first (14) and second (16) cutting tools disposed substantially between the first and second work piece support means such that they are operable to approach and cut the work piece from opposite sides, each cutting tool (14, 16) being movable in second and third directions, said second and third directions being substantially orthogonal to the first direction and said second and third direction being substantially orthogonal to each other, wherein the machine further comprises at least one elongate scraper bar (18, 52), the scraper bar having a main axis, said main axis being orientated substantially perpendicularly to the first direction and disposed so as to abut surfaces of the work piece adjacent to the area being cut.
