Abstract (en)
[origin: EP0412958A2] To be able to guarantee high cutting capacities with frame saws, a drive mechanism for the saw frame (1), having a stroke guide (4) consisting of oscillating levers (5) which act on the frame (1) in the manner of an articulated parallelogram and are articulated on crank arms (7), is proposed. The crank arms (7), which assume, in the middle stroke position of the crank mechanism drive (3), with the associated oscillating levers (5) a top position, can in this case be driven in rotary oscillation synchronously with the frame stroke about the middle position determined by this top position. <IMAGE>
