ABSTRACT:
Methods and apparatuses for registering the level of contents in a packaging material tube which is formed in a packaging machine and is continuously supplied with contents and sealed-off transversely for the formation of individual packaging containers filled with contents are previously known and include, int. al. sensing devices located in the packaging material tube. In order to facilitate cleaning and sterilization of the packaging machine, use is made, in the method according to the present invention, exclusively of sensing devices located outside the packaging material tube (6), in the form of a device (15) sensing the outside temperature of the packaging material tube (6), the device being, via a master unit (17), connected to a feeder device (12) which, in response to the signal of the sensing device (15) via the master unit (17), is regulated so that contents (18) are supplied at a suitable rate to the lower end of the packaging material tube (6).
