Abstract

A light-weight and structurally simple system for guiding the saw frame of a mechanical frame saw machine having a crank drive and a stationary machine frame on which the system is pivotally mounted. The system is composed of a vertically extending, flat inner guide plate pivotally mounted to the machine frame and carrying bearings mounted on bolts, and a guide part having the form of a plate, attached to the saw frame back, and provided with a laterally extending guide surface which bears against the guide plate and slides therealong during movement of the guide part relative to the guide plate, the guide part being provided with a vertical guide groove located, in the horizontal direction, midway between the ends of the guide part for engagement by the machine crank drive, and with two horizontal guide grooves presenting horizontal guide faces and extending in respectively opposite horizontal directions from respectively opposite ends of the vertical groove, the horizontal grooves and their associated guide faces engaging the bearings of the guide plate to be supported thereby. The guide part is provided, at the lateral side thereof which faces away from the guide plate, with at least one further guide surface extending parallel to the guide plate, and the system is further provided with a guide beam carried by the bolts to bear against the further guide surface in a manner to brace the guide part relative to the guide plate.
