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.
A device at an embroidery frame for a sewing machine, the device comprising an inner frame and an outer frame, between which inner and outer frames a hose is arranged, said hose being expandable through pressurization, whereby a textile material intended for embroidering is arranged to be clamped between said hose and said outer frame as well as tensioned over an area of the textile material intended for embroidering through pressurization of said hose after manual assembly of said inner frame and said outer frame and whereby said hose is arranged to through initial pressurization expand in an upper part of said hose and thereby clamp the textile material between said upper part of said hose and said outer frame as well as to through continued pressurization continue to expand in said upper part and in a lower part of said hose in a direction towards said outer frame and thereby impart on the textile material a tensioning, wherein the wall of said hose in thickness and shape is designed to, through pressurization, initially expand across said hose in said upper part and, through continued pressurization, continue to expand across said hose in said lower part.
A method for clamping and tensioning a textile material in an embroidery frame for a sewing machine comprising an inner frame, an outer frame and a hose arranged between said inner frame and said outer frame, which hose is expanded through pressurization and is pressurized initially such that it expands in an upper part, whereby the textile material is clamped between said upper part of said hose and said outer frame and said hose is thereafter further pressurized such that it is expanded in a lower part, whereby the textile material is tensioned in a direction towards said outer frame, wherein said hose is pressurised initially such that the shape of said hose is rendered to change across said hose in said upper part and is thereafter further pressurized such that the shape of said hose is rendered to change across said hose in said lower part.
A device at an embroidery frame for a sewing machine, the device comprising:
A method for clamping and tensioning a textile material in an embroidery frame including an inner frame, an outer frame and a hose arranged between the inner frame and the outer frame, the method comprising:
