Heating unit for heating the packaging sleeve and device comprising such a heating unit

摘要

A heating unit (11) comprising at least two heating devices (40) for at least partially heating the end region (10) of the packaging sleeve (6) to be sealed with hot air is described and illustrated. . The heating unit (11) includes an air supply device (41) for supplying air to be heated to the heating device (40), and each of the heating devices (40) is a heating element ( 55) and a nozzle unit (46) for blowing hot air produced by the heating device (40) onto the end region (10) of the packaging sleeve (6). Heating in order to be able to improve the leakage resistance of the sealed end region of the packaging sleeve without having to accept excessive expenditure and effort in terms of equipment and / or in terms of the method therefor Each of the devices (40) is individually connected to the air supply device (41) by at least one holder (49) and is individually held on the air supply device (41) by at least one holder (49). Has been proposed. [Selection] Figure 4
