摘要：The object of the invention is an apparatus for clamping a chipper knife (1) to a rotatable chipper disc (4) or drum so that the back surface (6) of the knife (1) is supported against a knife clamp (2) with a knife spacer (3), and that the knife clamp (2) and knife spacer (3) are movable relative to each other by means of the clamping element (5). The knife clamp (2) is provided with supporting surfaces (11, 12) which the back surface (6) of the knife (1) is adapted to lean against by at least two spaced-apart surfaces (11', 12'). The knife spacer element (3) includes a supporting surface (13) which is adapted to subject a front surface (14) of the knife (1) to a force acting between said supporting surfaces (11, 12) of the knife clamp (2) for bending the knife (1) between said supporting surfaces (11, 12) of the knife clamp (2) towards the knife clamp (2) so as to generate a compression stress in the free section of a front surface (16) of the knife (1).
