Eccentric Mandrel:
The eccentric mandrel on the stretcher roll can be adjusted so that the crown travels in concentric rings on the saw or in a spiral. When placed perpendicular to the radius of the saw, the rings will be concentric. Moving the eccentric mandrel slightly off-center will create a spiraling of the crown on the saw.
The 3-10-C accommodates saws up to 36″ in diameter and comes complete with a 1 HP motor for standard alternating current, magnetic switch, convenient foot pedal and a standard four-step centering bushing. The 3-10-C rolls to within 7″ of the eye on the largest saws and can work closer to the eye on smaller saws.
CAPACITY: 36″ diameter saws, tensioning to within 7″ of eye (92 cm saws, tensioning to within 18cm of eye)
MAX. GAUGE: 4 gauge (.238″ or 6.04cm)
STANDARD FEED: 40 feet/minute (12 meters/minute)
MOTOR: 1 HP gearhead (.75 kilowatts)
HEIGHT OVERALL: 58″ (147.3 cm)
FLOOR SPACE: 21″ X 41″ (53.3 cm X 104.1 cm)
TRUCK CRATE: 700 lbs. (320 kg)
OCEAN CRATE: 800 lbs. (370 kg)
CUBIC FEET: 53 cu. ft. (1.5 cu. meters)
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.
Options and Accessories
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.
