The invention relates to a device (10) for separating two superimposed films (12, 14), comprising a top tool (18) and an opposite bottom tool (20), both of which are embodied as a pivotable fork (22, 26) that can be moved from an open position to a closed position for gripping purposes. Grip plates (24, 28) which are provided with planar support areas and asymmetrically embodied cutting edges (30), and recesses (36, 38) that are located in the region behind the cutting edges (30) are configured at the free ends of the forks (22, 26). The invention further relates to a method for separating two superimposed films (12, 14) and a bag that is produced according to the inventive method. Also disclosed is a method for molding at least two tubes (112, 114) or ports into a web of tubular film. |
