摘要： A method for producing a bag from a tube including transverse lines of perforations delimiting tabs of the future bag, a rear tab of a first bag being opposite a front tab of the second bag following the first. A first step involves separating the first and second bags; a second step involves separating a piece of waste remaining on one of the bags between the two tabs. The first and second steps are carried out between a first pair of separation cylinders and a second pair of cylinders, the piece of waste being clamped between the cylinders of the first pair during the first step in order to be held on the second bag, then clamped and torn off by the second pair during the second step.

摘要： A method for manufacturing a bag includes a wall of the bag is passed along a placement drum for rotatably mounted handles; a handle is hooked onto the drum, legs of the handle extending backwards along a perimeter of the drum in the direction of rotation of the drum, the legs being connected by a cross member; same is completely turned over using a turnover drum so that the legs are at the front on the placement drum; and the handle is deposited on the wall.

摘要： A flexible bag comprising a first wall and a second wall superposed over the first wall, the walls being connected to each other along their longitudinal edges by two gussets. As per a bag formation process, successively: the bag is closed with a flap extending from one of the walls and held on the other wall to form a closed end of the bag; the first wall of the bag is gripped at a predetermined distance from the closed end with the lower grippers and the second wall by the upper grippers and the walls are separated to form a side on the gussets; the second wall is released by the upper grippers and the closed end is folded by a folding device on to the second wall, thus making the bottom.
