6. From the front of the machine there should be enough of a gap between the angle
bar and the clamping bar so that the canvas will “waterfall down” into the opening.
The operator should not have to feed the canvas in by hand in most cases.
7.
Be sure to position stretcher plates closer to the center of the artwork. Moving
them toward the outside rails will result in an uneven stretch; a few inches left and
right of center. Art larger than 30” may require moving the plates farther apart,
but try to avoid moving the plates toward the outside rails. The outside of the
stretcher frame already has strength from the (2) outside rails; fortify the center
where it is needed.
8.
Feed the loose end of the canvas into the gap and step on the
“clamping pedal”
once to engage the clamp. There should be at least 1.5” of excess canvas beyond
the bottom of the stretcher bar to allow the clamp to get a good hold.
