Abstract: A process for chemically bonding a screen fabric material to a frame structure for serigraphic printing purposes. The bonding or fastening process includes, providing a screen fabric material in taut communication to peripheral portions of a frame structure. A cyanoacrylate based adhesive is applied to the screen fabric portions in communication with the frame periphery. A chemically basic catalyst is then brought in contact with the applied cyanoacrylate adhesive to activate or accelerate the anionic polymerization of the applied adhesive for quick curing thereof. The use of methylcyanoacrylate, ethylcyanoacrylate and isopropylcyanoacrylate adhesives are provided for specific end-use purposes. A basic catalyst, in a spray mixture, consisting of aromatic amines is used for quick and easy anionic polymerization of the cyanoacrylate based adhesive.

Abstract: An adjustable stretcher device for positioning and holding frame structures of various dimensions and for biaxially tensioning a screen fabric across the frame structures for subsequent fastening. The adjustable stretcher is comprised of a generally rectalinear and flat base member, a pair of elongated opposing and perpendicularly disposed track members secured to the base member, and adjustable clamping members for slidingly engaging each track member. Elongated stretcher modules having sloping shoulder portions and a plurality of needles extending therefrom are provided for the adjustable communication with the clamping members. The adjustable movement of the clamping members on the track members and the adjustable movement of the stretcher module bodies with respect to the clamping members permit screen fabric materials to be biaxially tensioned across a frame structure placed within the perimeter of the stretcher module bodies.
