Abstract

A fabric tensioning mechanism for pulling taut a flexible material arranged in a support frame, which frame is controllably movable in X-Y directions in a sewing machine setup. The fabric tensioning device is particularly useful to tension flimsy materials. A tensioning mechanism comprises several pivotable clamps arranged opposed one another across the support frame. The clamps are pivotable on the frame, and at least one clamp is movable with respect to the frame toward and away from its opposing clamp a regulatable distance to effect regulatable tension within any material pulled therebetween.
