We're building a machine which pull and stretch the canvas over the
stretcher bars. It works just like this machine
http://www.tabmasteruk.com/DSCF0001.WMV
The only problem is to get a grip on the material (canvas fabric made
from polyester), we tried sharp pins and saw cog, when the sharp
teeths get a grip on the wooden strecth bars it can't pull the canvas
to get a good tension.
1. Do you have a solution to pull and stretch the canvas (only 2-3cm
of canvas)($25)
2. Do you know the manufacturer of rubber gripper to tension the canvas ($35)
3. a complete design of a canvas streching machine ($50)

We've allready found several machines which are not suiteable for our material:
- EZ Stretch Canvas Stretcher
- http://www.bespokemachines.com/
- http://www.tabmasteruk.com/quick%20canvas.htm
These machines are more suitebale for inkjet canvas which are thicker
and less flexible as our material.
