  • Device at an embroidery frame and method for clamping and tensioning a textile material
    Patent number: 6901870
    Abstract: The present patent application relates to an embroidery frame for a sewing machine and a method for clamping and tensioning a textile material. The embroidery frame comprises an inner frame, an outer frame and a hose arranged between the inner frame and the outer frame, which hose is expandable through pressurization. After manual assembly of the inner frame and the outer frame, a textile material intended for embroidering can be clamped between the hose and the outer frame and tensioned over an area of the textile material intended for embroidering through pressurization of the hose. The hose expands through initial pressurization in an upper part and clamps thereby the textile material between the upper part of the hose and the outer frame. Upon continued pressurization the hose expands in a lower part in a direction towards the outer frame and tensions thereby the textile material.
