Verfahren und Vorrichtung zum Herstellen eines Sackbodens |
摘要 |
The invention concerns a method and an apparatus for manufacturing a bag or sack bottom from tubular sections of paper or plastic web. Tubular sections of web material are fed into a feeding plane where they are subsequently sealed along selected seams by a sealing means. The sections are then inverted and fed in parallel to a scoring, gluing and folding section. The tubular section is then inverted again and passed to a pressing section. The tubular sections are stacked on top of each other in a partially overlapping manner as they are passed through the pressing section. After pressing, the tubular sections are passed to a separating station for again separating them before being passed to a packaging station. The invention concerns, moreover, an apparatus for operating the above mentioned method. |
