<p>A power frame saw including a bench frame on which a workpiece to be cut is mounted between a set of adjustable clamping braces. A saw frame which holds a saw blade is positioned within a housing and is displaceably mounted therein so as to be capable of being moved in a reciprocating stroke direction. The housing, in turn, is pivotably articulated to a machine frame arranged on the bench frame. A drive system is mounted within the housing and includes a crank disc, which is operatively coupled to the back portion of the saw frame. This back portion of the saw frame extends in the direction of reciprocating stroke movement of the saw frame and is provided with two widened portions which form web sections, both of which extend transverse to the longitudinal axis of the back portion. An arrangement is provided for displaceably guiding the web sections within the housing so as to be moved along the reciprocating stroke direction.</p> |
