摘要

The transverse welding and cutting equipment has a holder (18), on a second welding and cutting unit (16), having a spring-loaded counter holder acting in conjunction with the rail and two moveable clamps (28') with variable spacing. Independent drive units (10, 11) for operating different welding and cutting units are located on each side of the packaging tube (1). A holder (17) of one welding and cutting unit (15) carries a heated rail (22) and two moveable clamps (28) with variable spacing. A holder (18) on the second welding and cutting unit (16) has a spring-loaded counter holder acting in conjunction with the rail and two moveable clamps (28') with variable spacing.
