Abstract
A vertical packaging machine for packaging products is provided that includes a forming element with an upper mouth and a hopper upstream of the forming element. At least the hopper and the forming element form a conduit through which the product falls. A flow generator includes an injection device for injecting a gaseous fluid through a distributor for directing the fluid to the conduit. The distributer has an inlet mouth for receiving the gaseous fluid and an outlet mouth with an area smaller than the area of the inlet mouth. The injection device is controlled by a control device that is configured to cause the injection device to perform an injection for each product to be packaged in one and the same package, the start and end of which depend on the position of the product with respect to the upper mouth and the outlet mouth.
