Abstract: The invention relates to a powered reciprocating saw, in particular to a pruning saw. To simplify use of the saw a clamping mechanism is provided which holds an object in position while it is sawn. The clamping mechanism is mounted at the front portion 4 of the housing of the saw near the saw blade 20. The clamping mechanism comprises: a slide element 30 for sliding movement in cutting direction C of the saw blade, a supporting member 30; and a clamping arm 40 being rotatably mounted on the slide element 30, by means of a one way rotary clutch 42 such that the arm can freely rotate in one direction only, in which direction the clamping arm 40 moves towards the support member 30 to clamp an object therebetween in a clamping position below the saw blade for sawing it. When the saw is in use, it vibrates due to its reciprocating parts. Since the clamping arm 40 has a moment of inertia with respect to this axis of rotation of the one way rotary clutch 42, the oscillating movement is transformed into a stepwise, progressive rotational movement of the clamping arm which thereby closes automatically to clamp an object to be sawn.

Abstract: A quality of a sheet material, such as unprinted paper, is determined by acquiring an image of the surface of the sheet material and analyzing the image to determine the intensity of local nonuniformity as a function of scale of formation. A meaningful interpretation of the sheet material quality is possible using the scale of formation. Correlations between sheet material qualities, such as cloudiness, cross-directional strength, etc., and the scale of formation allow for rapidly acquired images to provide useful indicators of sheet material quality. Normalizing the sheet material formation line with respect to a desired standard sheet allows for a useful graphical display of the sheet material quality.

Pour ce faire, on utilise de la résine cationique conférant la résistance à l'état humide, que l'on laisse se lier aux fibres. On mélange ensuite les fibres traitées avec le solde non traité de fibres, à un certain stade en amont de la machine à papier. Normalement, les fines de classage lors de la retrituration ne dépassent pas 2 à 3 %.
