摘要： 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. The outputs from the photoelectric scanner, the electric eye and the tachometer are used in association with a microprocessor for controlling the position of the registration marks with respect to the lands so as to form transverse seals on the pouches between the printed matter associated with each pouch.
