The Armstrong stationary band and gang saw stretcher rolls are of compact design but have been built to withstand steady, hard use, and the extreme pressure required to tension saws uniformly and quick.

In designing this stretcher roll, as with other Armstrong filing room equipment, one thing has been kept in mind – to provide a machine to do the job satisfactorily, with the least amount of time and effort of the operator.

1. The rolls are made to extract specifications of a special high grade, tempered tool steel, ground accurately and to a uniform crown.
2. Drive gears are enclosed and provided with an oil reservoir so they run in oil.

The No. 3-10 Armstrong Stretcher Roll is capable of easily tensioning the heaviest gauge gang saw blade and has many unique features that make it the most advanced design on the market today.

SPECIAL FEATURES

1. Heavy duty anti-friction bearings and nylon thrust bearings, combined with rolls with hardened sleeves, provide greater precision, maximum life, and simpler maintenance.
2. A heavy frame, and an open front similar to that used on punch process, make it easy to handle saws as wide as 10".
3. The same large size rolls, and the same pressure screw with ball contact used in Amrstrong No. 4, 5 and 6 movable band saw stretchers are incorporated in this new roll, assuring all the sensitivity and long wear found in much larger machines.
4. A 1 H.P. gearhead motor provides power for the heaviest tensioning.
5. An entire new idea in roll mounting makes it possible to change a complete set of rolls, with no loss of alignment, in about three minutes average time – an important advantage to saw shops particularly.
6. Since this is a stationary roll, with one roll driven, there are few wearing parts, and the drive is simplified.
7. The No. 3-10 stretcher is available with an optional steel base as shown, or it can be mounted on the bench as desired. The steel base offers sturdy support and convenient motor mounting.
8. Simplicity of design makes it possible to supply this new stretcher at very reasonable cost.
