Abstract

The parallel sawing mechanism has a stationary holder and a saw housing sliding in relation to the holder in a non-horizontal direction. A saw blade performs a linear movement in the housing in guides, and cylinder between holder and housing controls the feed movement as the blade is lowered. The cylinder (7) merely offers resistance, being equipped with an out-let valve, and the saw housing (1) is coupled to its head to slide along a track lying in the plane of the saw, and not at right angles to the overall feed movement of the head, in relation to the head. A control mechanism only opens the cylinder outlet valve when the housing assumes a given end position in relation to the head, so that when working the housing performs a reciprocating movement in relation to the cylinder head, the lower end of which is the end position concerned.
