Machine and method for vertical packaging

摘要

Vertical packaging machine and method for operating the machine, which comprises a packaging operation that at least comprises a stage for the continuous feeding of a laminar film (4), a stage for the forming of the laminar film (4), with a laminar tube (5) being obtained, and a drive stage in which by means of at least two drive belts (30) the movement of the laminar tube (5) is caused. It also comprises a control operation in which the position of the belt (30) of each advance module (3) in relation to the forming tool (2) during the packaging operation is controlled, acting in an automatic manner on at least one displacement module (7) that operates the corresponding advance module (3) when slippage or risk of slippage of at least one of the belts (30) with respect to the laminar tube (5) is detected.
