Abstract
Sealing rollers (23, 24, 25) serve for connecting tear-open strips with a film web (10) by applying heat and pressure, the sealing rollers (23, 24, 25) resting against the film web (10) in the region of the tear-open strips. Opposite of the sealing rollers (23, 24, 25) there are positioned counter rollers which make it possible to transfer pressure by means of the sealing rollers (23 to 25). The sealing rollers (23 to 25) are heated, specifically by radiant heat from a heated housing (31), which serves as a carrier for the sealing rollers (23, 24, 25).
