Vertical tubular bag machine, has verification device provided at tubular bag machine for verifying collision of tubular bag, where verification device is provided downstream to separation device

摘要

The machine has a longitudinal welding device (7) for welding a foil tube (6) by a longitudinal seam (8). A separator (13) is provided for separating a tubular bag (25) from the foil tube. A supply line (16) is provided for supplying a fluid product into the foil tube. A control device (18) is provided for controlling the height of the fluid in the foil tube. A verification device (19) is provided at a tubular bag machine for verifying the collision of the tubular bag, where the verification device is provided downstream to the separation device. Independent claims are also included for the following: (1) a method for verifying collision of a filled tubular bag (2) a method for verifying the density of the filled tubular bag.
