ABSTRACT:
Sealing heads for heat sealing the tops of continouously movable upright pouches are spaced angularly around a continuously rotatable turret and seal the pouches after steam has been introduced into the pouches and as the pouches move in an arcuate path extending around the turret. Each sealing head includes a pair of heated sealing bars and further includes a cam-operated actuator which sequentially lowers the bars, closes the bars, opens the bars, and then raises the bars as the bars rotate with the turret.
