Abstract:
1. 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.
