Abstract
The method proposed calls for a crush blade (9), which separates cross-sealed plastic bags from each other, to be built into a cross-sealing jaw. The crush blade (9) has a zig-zag crush edge (16) made up of V-shaped grooves (17,18) laterally staggered with respect to each other. Joining with the angles (26,27) of the crush edge (16) are sharp cutting edges (24,25) which run in the direction of rotation (19) of the blade (9). The cutting edges (24,25) make an angle with the plane (23) of the crush edge (16). This ensures a long life of the blade (9) and makes it easy for the consumer to tear open the bags.
