  • Frame having shiftable bars with flexible ends for securing fabric using adhesive
    Patent number: 5136797
    Abstract: A screen printing frame assembly which includes adjustable tensioning bars adjacent the frame peripheral edge. Screen mesh fabric is mounted to the tensioning bars by adhesive and the bars are drawn toward the frame edge to stretch the fabric to a uniform tautness for printing. A mounting tool may be employed to secure the fabric in position prior to gluing to the tensioning bars. Each tensioning bar may also include resilient corner pieces to allow for corner slackening of the fabric.
