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).Field of SearchWITH CLOSURES AND PLUGSAir and dust cap Combined Air cap Dust cap With separate closure attaching (e.g., cap or plug) By applying a separate preformed closure (e.g., lid, cap) By plugging closure into container Separate closure REGISTER CONTROL Of package and filled receptacle closing or opening Cutting and/or shaping means Concentric with or at infeed of closure Blank cut-off only Plunger structure Closure inserting means Horizontal infeed With cutting, punching, piercing, severing, or tearing Means feeding plural workpieces to be joined Delivering cut part in sequence to serially conveyed articles And securing separate part over hole or aperture | |
