Abstract: A method includes a bag forming process with a bag wicketing machine having a sideweld seal head that receives plies of web material, conveys the plies through the sideweld seal head, seals the plies together, cuts the plies to form a bag blank, and moves the bag blank onto an exit conveyor. Pressurized air from nozzles of a pneumatic blow down bar is directed at the bag blank. With an energized laser operatively mounted on the pneumatic blow down bar, the position of the pneumatic blow down bar relative to the bag blank and the exit of the sideweld seal head is adjusted so that a beam emanating from the laser is positioned against the bag blank at a desired location where pressurized air from the nozzles of the pneumatic blow down bar is directed against the bag blank and forces the bag blank into engagement with the conveyor.
