Abstract
In packing machines of the type which manufacture packing containers from flexible, tubular material, the contents are fed via a filling pipe opens into the tube. The level of contents in the tube is controlled by means of a float which is connected mechanically to a valve located at the mouth of the filling pipe. On filling of highly viscous types of contents, an arrangement for the control of the flow of contents is used instead, in accordance with the invention, which comprises a sealing device surrounding the filling pipe which on the one hand prevents the contents from penetrating upwards into the tube, and which on the other hand is used for controlling the feed of contents in that its vertical position is monitored by means of a monitoring device surrounding the tube and allowed to control a pump for the feed of contents via the filling pipe.
