Abstract (en)

[origin: EP0722899A2] The web (3) is drawn over rollers (4, 5, 6) and its tension across its width is equalised. The web (3) is preferably a paper of film track. A tension equalising roller (5) reverses the web (3). The equalising roller (5) is pivoted about a pivot axis (8) which is essentially perpendicular to the roller (5). The equalising roller (5) is pivoted by detecting and regulating a rotary moment exerted on the roller (5) by the web (3). The appts. for carrying out the method has the equalising roller (5) mounted on a shaft (7) to rotate freely about its longitudinal axis. The shaft (7) is supported in a pivot bearing (10) held in a frame (11). The shaft (67) is held either side of the roller (5) and guided in buffers. The shaft (7) is movably held by a toothed gear and supported by roller bearings.

Abstract (de)

Ein Verfahren und eine Vorrichtung zum Ausgleich von Spannkräften über die Breite einer laufenden Bahn (3) verwendet eine Spannungs-Ausgleichswalze (5), welche um eine Schwenkachse (8) schwenkbar gehalten ist. Beim Auftreten einer Spannkraftdifferenz über die Breite der Bahn (3) wird die Spannungs-Ausgleichswalze (5) mittels einer Drehmomentenregelung soweit aktiv verschwenkt, daß die Spannkräfte in beiden Bahnälften ausgeglichen werden. <IMAGE>
