Rubber adhesives

The following is posted on behalf of Valerie Carson

    I have a Blackwork silk embroidered pillow cover, late 16th
    century awaiting treatment.  Some friendly picture framer has
    created a sub frame of linen. He/she then horrors of horrors
    adhered this subframe to the edges of the pillow cover,using a
    rubber adhesive. I was able to remove the sub-frame mechanically
    with no damage, but 13 mm of unsightly adhesive is covering the
    perimeter embroidery.

    I have tried various solvents on test sections of the
    sub-frame (which will not be retained). Has anyone out there
    had similar experience and did you solve this vexed question?
    many thanks in anticipation.
