摘要

Device (1) comprises a bearing surface (7) over which a foil sheet (3) is moved, feed devices (10) for bulk material (11) assigned to troughs in the bearing surface, and welding and/or gluing devices (13) for producing longitudinal seams defining the inner side of pockets. Preferred Features: The foil sheet glides over the stationary bearing surface. A holding-down device (9) made of a textile material, especially carpet, and arranged opposite the bearing surface presses the foil sheet flat against the bearing surface.
