Abstract
A clamping device and method for a conventional sewing or embroidery machine has a pair of movable arms. Each of the arms includes a fixed section and a movable section for receiving material or item to be embroidered therebetween. A manual lever allows the movable arm to be raised for insertion of the material and a scale on the arm allows the depth of insertion to be easily determined for accurate insertion. Each arm is movable along a slotted mounting plate affixed to the sewing machine proximate the sewing head. The clamping device provides uniform, taut material for accurate, smooth embroidering.
