Introduction
The Canvas Stretching Machine is a fully pneumatic canvas stretcher capable of
stretching original art on canvas, giclee prints and any fabric suitable for stretching. The
following is a list of operating parameters that should be observed to ensure a safe and
efficient stretch:
1. Minimum amount of excess canvas 1.5”
2. Minimum stretcher width .75”
3. Maximum stretcher width 2.5”
4. Maximum supply air 120 psi
5. Minimum supply air pressure 90 psi
Safety Precautions
Air Pressure: before applying air to your machine, adjust the regulator at your
compressor to produce 95 psi. If you are using a pneumatic staple gun please be sure to
provide what the manufacturer recommends, this may require you to provide a 2 way
manifold.
All of the air cylinders have been thoroughly operated, tested and held to a very high
standard. The Clamping Bar has a dedicated internal pressure regulator and it is set to a
point that will not exceed the Stretcher Bar pressure by more than 10 psi. This is to
ensure that the canvas is permitted to slip just enough to minimize overstretching. The
operating pressure of the Clamping Bar is preset to 50 psi….Do Not Adjust This Setting!
CAUTION: the clamp and stretcher bar move slowly, they are deceptively powerful.
The force behind them can damage your fingers, please ensure that your hands and
fingers are clear of the clamp at all times. DO NOT place your fingers between the
Clamping Bar and Front Plate at anytime.
