Method and device for producing a textile hollow body

A method for fabricating a hollow body from blanks obtained from a web of material, comprising:

• providing an apparatus for fabricating a hollow body, said apparatus including a main part in the form of a ring-like, self-contained plate, and two side plates, the contours of which generally correspond to those of the main part,
• providing a main part blank generally corresponding in shape to an inner wall of said main part but wider than said inner wall to define a seam allowance,
• placing said main part blank on said inner wall of said main part and firmly holding said main part blank in place by at least one of a suction force and an electrostatic force,
• providing two side part blanks generally corresponding in shape to inner walls of said side plates but larger than said side plates by one seam allowance on all sides thereof,
• placing said side part blanks on said inner walls of said side parts and firmly holding said side plate blanks in place by at least one of a suction force an electrostatic force,
• guiding each of said side plates up to a rim of said main part so that said seam allowances of said side plate blanks firmly held in place at said side plates surroundingly locate at an inner side of said seam allowance of said main part blank firmly held at said main part,
• stitching said seam allowance of said main part blank to said seam allowances of said side port blanks to form a hollow body, and
• discontinuing said at least one of said suction force and electrostatic force and retracting at least one of said side plates from said main part and extracting the hollow body.
