  • Method and apparatus for the manufacture of a tube made of film on a cellulose basis which an insert reinforces
    Patent number: 6797100
    Abstract: The invention relates to a film tube (10) based on cellulose which is produced by extruding an aqueous cellulose-N-methyl-morpholine-N-oxide (NMMO) solution through a ring nozzle (21) onto a lining (3). The film tube (10) is manufactured by means of a vertically descending spinning in a spinning vat (12) in which a spinning bath (11) is located. The film tube (10) which is submerged in the spinning bath (11) passes through an air gap (9) between the underside of a nozzle block (7) and the upper surface of the spinning bath (11) and, internally, is pressurized, supported and slightly stretched in a transversal manner by compressed air. The film tube (10) is filled with an inner bath solution (31) via a supply tube (18). An idle roller (13) is situated near the bottom of the spinning vat (12) in order to guide the film tube (10) around and, afterwards, out of the spinning vat (12) in an upward sloping manner. The film tube is laid flat along a contact section (27) of the idle roller (13).

  • Shirred packaging tube
    Patent number: 5045020
    Abstract: An article is disclosed comprising a cylindrical hollow rod, composed of a shirred packaging tube, with an internal bore having a circular cross-section and ending in cavity openings at the two end faces of the hollow rod, in combination with a sheathing which surrounds the hollow rod, leaving the cavity openings free, and an annular body at one of the two cavity openings. The annular body comprises an annular disk, whose inner side face bears directly against the adjoining end face of the hollow rod. The outer side face of the disk is at least partially surrounded by the sheathing. The internal bore of the disk remains free of the sheathing and contains elements for fixing the disk to a cylindrical filler horn.
