Armstrong 310-C Stretcher Roll

SKU ARMSTRONG-310-C-STRETCHER-ROLL

Armstrong 310-C Stretch Roll

  • ARMSTRONG 310-C STRETCHER ROLL DESCRIPTION

    Specifications: For circle saws up to 36” (92cm) in diameter.

    Armstrong stretcher rolls uniformly tension saws as much as 10 to 20 times faster than is possible with a hammer and anvil, and with far less effort. These machines are simple to operate, heavy duty in design and perform well on even the heaviest gauge saws. Armstrong 3-10C stretcher gently rolls the same tension all around the saw providing greater uniformity and control over the tensioning process.

    UNIFORMITY:

    Stretcher rolls tension saws smoothly and uniformly from the center of the saw to the gullet line.

    HAMMER MARKS ELIMINATED:

    Eliminating hammer marks helps to ensure top performance from even thin kerf saws, such as those used on modern guided multi-saw rip machines.

    HEAVY-DUTY BUILD:

    The sturdy cast-iron or steel frame, steel floor stand and heavy-duty anti-friction bearings assure years of trouble-free service. A 1 HP motor provides power to tension even the heaviest gauge saw.

    CONVENIENCE:

    The foot pedal control starts and stops the rolls. The saw quickly adjusts in and out on steel rails for precise positioning of the rolls.

    LINEAR BEARING SLIDE CARRIAGE

    The Linear bearing slide carriage provides wonderful ease of saw movement and an integrated Leveling Roll system. It is constructed from solid anodized aluminum rigidity and long useful life. An eccentric mandrel for Saw centering is also included. Available both as original equipment on new machines or as a Direct Bolt-on Replacement for existing Armstrong 3-10-C stretcher rolls.

    STEPPED SAW CENTERING BUSHING:

    Each machine comes with a stepped bushing to handle saws with center holes of 1″, 1-1/8″, 1- 1/4″, 1-38″. Single step bushings for larger eyes are available at extra cost. A special mandrel is also available for saw bores down to 1/2″.

    DIAL INDICATING PRESSURE SCREW:

    Completely interchangeable with the standard screw, the optional dial indicating pressure screw shows the amount of pressure being applied to the saw directly on the dial. This option is very useful in maintaining and repeating the correct pressure and in training new filers.

    LEVELING ATTACHMENT:

    The hardened and crowned rollers are set to the desired height and the tensioning rolls pull the saw through without adding tension. The optional attachment is quickly installed and removed and is used for both standard circle and Strobe saws.

    STRETCHER ROLLS:

     

    The standard tensioning rolls included with each machine are ground to a 4″ crown. This crown works very well on a wide range of circle saws.

     

    LEVELING ROLLS:

    A concave leveling roll is available. Armstrong’s part number 7337 is a fully concave roll, is ideal for all saws.
