Abstract (en)
[origin: US5913764A] PCT No. PCT/EP96/01540 Sec. 371 Date Dec. 19, 1997 Sec. 102(e) Date Dec. 19, 1997 PCT Filed Apr. 11, 1996 PCT Pub. No. WO97/00768 PCT Pub. Date Jan. 9, 1997A method for manufacturing flat-bottom bags with a glued-in bottom lining includes the steps of applying a contact adhesive, which develops a desired adhesive force only when two surfaces, both of which are coated with the contact adhesive, are pressed against one another, onto a starting material for the bag, subsequently closing the starting material into a tube, supplying the tube to a bottom-laying station to produce a flat-positioned bottom of the bag, and completing gluing by exertion of pressure on the flat-positioned bottom of the bag after the bottom lining has been placed upon the flat-positioned bottom.
