PCT No. PCT/SE95/00133 Sec. 371 Date Aug. 8, 1996 Sec. 102(e) Date Aug. 8, 1996 PCT Filed Feb. 9, 1995 PCT Pub. No. WO95/21777 PCT Pub. Date Aug. 17, 1995The invention relates to a method and an arrangement for closing of at least one end of a tube to protect the tube (8) against internal dirtying. According to the method, a strip (5) comprising a number of plugs (4) is fed up to a position in front of a tube (8) situated in a punch sleeve (9), at said position a plug (4) in the strip (5) is in a position just in front of the tube end (12), whereupon a punch (7) presses the strip (5) with the plug (4) against the tube (8) and the punch sleeve (9), so that the punch (7) in the end of its working stroke after pressing the plug (4) into the tube end (12) is punching out the plug (4) from said strip (5). The plug (4) formed for closing of a tube end is together with plugs, formed in the same way, integrally formed one after another at a predetermined distance in a longitudinal row in a continuous strip (5). |
