<p>An improvement in a bundle breaker (1) having first and second adjacent but longitudinally spaced upper and lower clamping surfaces for breaking progressively a bundle (2) of sheets along a weakened plane from a log (4,4'). The improvement includes first and second compliance structures positioned between the first and second upper and lower clamping surfaces. The first and second compliance structures (20,26) include a device for detecting the height of the log (4,4') and a variation setting device for reducing the distance between the upper and lower clamping surface a selected increment after detecting the height of the log (4). The compliance structures (20,26) preferably include fluid pressurized structures (21,27) which not only detect the height of the highest log when a plurality of logs in side by side relation are broken simultaneously but also apply even pressures to all of the logs (4,4') and bundles during clamping and breaking even though one or more may have different heights. <IMAGE></p> |
