Thus, for any changes in the dimensions of the absorbent pads new molds are required. Because of the relatively high production costs, such absorbent pads have not yet enforced in practice. Typically, therefore, suction pads are used with open cut edges, so that it inevitably comes to exit the absorber material from the absorbent pad.

In particular, it is preferred that the absorbent body does not extend into a seam of the tubular bag.
