Abstract
A sawguide positioning method for circular gang saws mounted on a single saw arbor shaft. A guide bar is positioned generally parallel to the saw arbor shaft. A plurality of sawguide pairs are slidably mounted on the guide bar for longitudinal axial travel thereon. The guides extend on either side of each of the circular saws. A pair of opposed sawguide positioning wedges are threadably mounted on a selectively rotatable shaft having a right hand threaded end and a left hand threaded end, the axis of the shaft being generally at right angles to both the saw arbor shaft and the guide bar. The wedges are threaded on to the selectively rotatable shaft with their vertices innermost. The threaded shaft has an enlarged diameter portion or disk intermediate the threaded ends which is rotatably positioned within matching recesses in the opposed faces of the sawguides. Selective rotation in either direction of the shaft causes axial travel of the positioning wedges along the shaft toward or away from the disk thereby repositioning the sawguides and changing the spacing between the saw blades. Confinement of the disk on the shaft within the mating recesses prohibits any longitudinal translat…
