    摘要： A bandsaw machine with a base on which a workpiece table is mounted and a member pivotally mounted to the machine base. The base includes a pair of clamping jaws for the workpiece with the jaw closest to the pivotal mounting being adjustable and with the other jaw being fixed. The pivotally mounted member includes at least two reversibly driven pulleys, an endless saw band extending partially around and between the pulleys and a pair of guides for the saw band with the guide closest to the pivotal mounting being adjustable and with the other guide being fixed in the running direction of the saw band. Both guides are mounted to the pivotally mounted member so that in those instances where the plane of rotation of the reversibly driven pulleys is inclined to a feed plane defined by the pivotal movement of the pivotally mounted member, they will direct a portion of the saw band between the pulleys into the feed plane for cutting the workpiece. A control arrangement is provided for automatically and simultaneously adjusting both the adjustable clamping jaw and the adjustable guide.

    摘要： Method and machine for sawing a workpiece by means of a cutting tool, such as a band saw or saw blade, carried by a support. A hydraulic cylinder device controls the travel of the support and consequently the feed of the cutting tool. The working chamber of the cylinder device has a constant pressure which is a multiple of the maximum force opposing the feed of the tool. The rate of feed of the cutting tool into the workpiece is substantially constant owing to the fact that the liquid in the other chamber of the cylinder device opposed to the working chamber is made to flow out of the other chamber at a constant rate.

    摘要： A band saw having a pivotal arm supported for articulation on both sides of the saw blade and preferably above the surface upon which the work is to be cut is disclosed. The band saw includes a frusto-conical drive wheel and means for guiding the saw blade in slip condition on said drive wheel. Also disclosed are guide means carried by the pivoted arm and formed to direct coolant on the saw blade as well as impart a positive camber to the blade. The saw is provided with a fluid activated controlling means for raising and lowering the pivotal arm which includes a combined gas-liquid system in which the flow rates of the gas and liquid may be pre-selected to control the rate of descent of the arm.
