Stretcher Bar is Hanging Up

In nearly every case this is caused during transit, the cylinders and their mounts are

"forced" out of alignment. This is best resolved over the phone.

If you are experiencing this problem please do not hesitate to contact us at 614-861-4582

and ask for Dave.

The Canvas is slipping during a stretch

The Clamping Bar is preset to 50 psi, located beneath the deck; this regulator should not

be tampered with unless you have been instructed by us to do so. Changing this setting

may cause severe damage to the Clamping Bar and will void your warranty. Do not

change this setting. Most stretches are done at no more than 30 psi; this will produce a

nice tight stretch with giclee canvas. Heavy canvas and oversized art may require more

pressure, but it should not exceed 50 psi. That is why we have preset the clamp to 50 psi

this will allow for a certain degree of "slip". If the clamp is preset to 50 psi and the

stretching pressure exceeds 50 psi, then there will be slipping.

Stretcher Bar is lifting when stretching

This is by design. Smaller artwork will tend to rise very easily and large artwork may not

rise at all, but that is fine. Typically, the artwork will rise about 3-4", as shown in the

photo below. The operator should not "push down" on the artwork in an effort to keep

the artwork flat. Pushing down will tend to force the canvas out of the grasp of the

clamping bar; this would be equivalent to increasing the stretching pressure past 50 psi.

Under normal operating conditions the Stretching Bar will rise a little above the top of

the Clamping Bar as the stretching pressure is increased. The closer the stretching

pressure is to the set point of the clamping bar the more likely it is to rise.

This is not an issue unless the bar remains in this position or there is excessive play. If

this occurs contact us.
