<p>In a band-saw machine including a machine stand defining a substantially horizontal workpiece support region, first and second clamping jaws mounted on the stand, with the first clamping jaw being mounted to move horizontally toward the second jaw for clamping a workpiece between the jaws, a machine head mounted above the support region, and supported for vertical displacement relative to the machine stand, an endless saw band mounted in the machine head to present a cutting reach extending above and across the support region, and two saw band guides disposed to respectively opposite sides of the workpiece support region, each associated with a respective clamping jaw and each holding the saw band in position to cut a workpiece, the guide associated with the first clamping jaw is mounted on that jaw to be displaced vertically without tilting relative thereto, a connecting member is connected between the guide associated with the first jaw and the machine head for transmitting the cutting reaction forces imposed by the saw band on that guide to the machine head the connecting member is mounted in the machine head for permitting the connecting member to move relative to the head in the direction of movement of, and together with, the first clamping jaw, and the first clamping jaw is dimensioned to extend toward the machine head at least to the maximum height of a workpiece which the machine is arranged to cut.</p> |
