Abstract: For a device for cutting plants with a cutting line (36, 38) which rotates around an axis of rotation and is wound on a reel (13), wherein a slide (16) releasably locks the reel (13) by means of a cam (26) with respect to elements which rotatingly take it along, wherein the length of the free end (37, 39) of the cutting line (36, 38) can be adjusted by unlocking the reel (13), wherein the slide (16) is displaced out of its locked position into its unlocked position by means of centrifugal force in the course of the shortening of the cutting line (36, 38), the cutting line adjustment is simplified and functionally improved in that the slide (16) is maintained in its locked position only by means of the force equilibrium of the mass support forces between its cam (26) and a detent (28) on the reel side, out of which it is displaceable by centrifugal force into its unlocked position, so that the reel (13) can rotate in respect to the cup (12), wherein the cam (26) is returned into the locked position by the mass

Abstract: A hand belt sander has a housing, a drive roller and a deflecting roller both rotatably supported in the housing, the deflecting roller being arranged at a distance from the drive roller movable between a substantially axes-parallel arrangement and out of the axes-parallel arrangement with the drive roller, an endless sanding belt guided along the rollers, a guide plate located in the housing and carrying a control plate with an end for receiving the deflecting roller and being displaceable together with the control plate, a lever arm sensing a position of the sanding belt by a stop part and acting on the position of the sanding belt, a swivel arm around which the lever arm is swivelable and which extends perpendicular relative to the guide plate. The swivel arm sits in the guide plate. The control plate is swivelable around the swivel axle together with the ends and extends toward the guide roller so as to form the swivel arm in a one-piece element, and also carries the stop part.
