Air feeding device for a vertical tubular bag making machine, and method

摘要

The arrangement has a vertical fill tube (2), a funnel (6) above the tube, a shaping tube (8) concentrically enclosing the fill tube to form an annular gap between them, a fan (10) for blowing air into the fill tube via a connecting tube (11) and for influencing the falling product in the tube and a suction device (12) for sucking the air out of the fill tube. An air flap (13) within the tube is actuated by a drive (14) connected to a controller (15). An Independent claim is also included for a method of operating an air delivery arrangement for a vertical tubular bag production machine
