Abstract

Die Erfindung betrifft eine Einrichtung zur Bandspannung an einer Breitschleifmaschine, insbesondere eine Breitbandschleifmaschine zum Bearbeiten von Oberflächen von insbesondere flächigen, ebenen Bauelementen, z. B. aus Holz bzw. Holzwerkstoffen, die ein einfaches und funktionssicheres spannen eines Schleifbandes ermöglichen soll. Dies ist dadurch gelöst, dass den Enden resp. Lagern (22) der Spannwalze (21) je ein Doppelkolbenzylinder (23, 24) zugeordnet ist, deren Kammern (25, 26) für ein Fluid mittels Verbindungsleitungen (27, 28) über Kreuz miteinander verbunden sind.

Figure imgaf001
The invention relates to a device for belt tension on a wide grinding machine, in particular a wide-belt sanding machine for machining surfaces of particular flat, planar components, for. B. wood or wood materials, which should allow a simple and reliable clamping of an abrasive belt. This is solved by the ends resp. Bearings (22) of the tensioning roller (21) each associated with a double piston cylinder (23, 24), whose chambers (25, 26) for a fluid by means of connecting lines (27, 28) are interconnected crosswise.
