At the same time the bottom slice of bread containing the
filling travels along the lower conveyor until it makes
contact with a “V” shaped locating and centring gate
protruding between the conveyor cords.A second
photoelectric sensor detects this slice of bread and activates
the lift table.This rises from below the conveyor lifting the
bread clear and thus preventing further motion.
