Abstract:
In apparatus for pouch forming, filling and sealing, a printed web, having registration marks at locations where transverse seals are to be formed in order to form a pouch, is fed through drive rolls; over a plow which forms a longitudinal fold in the web; around a sealing wheel having lands which the web contacts to form transverse pouch-forming seals; around a filler where product is poured into the pouches; past a top sealer and a cutoff where the pouch forming is completed and the individual pouches are severed by knives. A photoelectric scanner scans the registration marks and produces a pulse when each passes the scanner. An electric eye cooperating with a disk driven by the machine determines the position of the sealer lands. A tachometer driven by the machine produces pulses proportional to the speed of the machine. A stepping motor continuously drives the drive rolls.
