Abstract: A clamp (10) having at least one clamping assembly (11) comprising a base plate (17) and a pair of tension elements (14, 15), the base plate (17) including a pair of oblong holes (16) which converge towards a central line, each of the two tension elements (14, 15) being fully or partially curved at its peripheral face, the peripheral face being made of a skidproof “non-slip” material, a respective tension element (14, 15) being mounted in a respective one of the two oblong holes (16) and positioned such as its axis is substantially perpendicular Lo the base plate (17), the tension elements (14, 15) furthermore being arranged, such that the curved peripheral faces thereof are exactly opposed to each other, and the tension elements (14, 15) being slidable in their respective oblong holes (16) by means of a common slider (155), and wherein they are rotatably seated by means of ball bearings (20), such that they can freely rotate about their own longitudinal axis, wherein, on one hand, the distance be

Abstract: A clamping member (11) for a wood clamp (10) is provided and comprises two spaced engaging elements (14, 15), each shaped as right oval cylinders. The engaging elements are rotatably mounted to a support plate (17) and are arranged to slide relative to support plate in respective slots (16) which converge. A workpiece is arranged to be clamped between the engaging elements when it is moved in the direction in which the slots converge as movement of the workpiece causes the engaging elements to slide in the converging slots thus further gripping the workpiece and also rotate until such time as the engaging elements clamp the workpiece and prevent further movement of the workpiece.
