摘要： Messerschärfvorrichtung mit: zwei Wetzstäben (24; 25), die an einem Sockel (2) schwenkbar angeordnet sind, und die zu einander V-förmig angeordnet sind, wobei die V-förmige Anordnung der Wetzstäbe (24; 25) der Einführung eines Messers dient.
Die Wetzstäbe (24; 25) weisen wenigstens je einen Schärfeinsatz (30) auf; wobei die Wetzstäbe (24; 25) in einer Ruheposition (19) durch die Kraft jeweils einer Feder (29) auf einem vorbestimmten Abstand in ihrer V-förmigen Anordnung zueinander gehalten werden.
Die Wetzstäbe (24; 25) sind in einer Schärfposition (1) mit Einführen des Messers bei Kontakt des Messers mit den Schärfeinsätzen (30) gegen die Kraft der Feder (29) auseinander spreizbar.
Wobei die Wetzstäbe (24; 25) über einen einzigen Haltepunkt (42) an dem Sockel (2) gehaltert sind.

摘要： The invention refers to a backing pad (2) for a hand-guided polishing or sanding power tool, comprising
- a support layer (4) made of a rigid material, the support layer (4) comprising a connection element (6) on its top surface (8) for connection of the backing pad (2) to a driving shaft (18) or an eccentric element of the polishing or sanding power tool,
- a damping layer (10) made of a resilient material, the damping layer (10) being fixedly attached to a bottom surface (12) of the support layer (4), and
- an adhesive layer (14) for releasable attachment of a polishing or sanding member to the backing pad (2), the adhesive layer (14) being fixedly attached to a bottom surface (16) of the damping layer (10),
wherein the bottom surface (12) of the support layer (4) is provided with reinforcement elements (24, 26, 28; 46; 50, 52) for enhancing flexural rigidity of the support layer (4), and the bottom surface (12) of the support layer (4) is further provided with recesses (30) formed between and at least partially limited by the reinforcement elements (24, 26, 28; 46; 50, 52),
It is suggested that the reinforcement elements comprise reinforcement ribs (24, 26, 28) comprising a plurality of polygonal geometric elements (36), each element (36) having an essentially polygonal rib design and neighbouring elements (36) being located next to each other and/or offset in respect to each other, wherein during manufacture of the backing pad (2) the resilient material of the damping layer (10) enters into the recesses (30) and after curing of the resilient material entirely fills the recesses (30).
