ABSTRACT:
An insertion machine includes an insert supply station 10 located alongside a conveyor 30. Associated with the supply station 10 are a selector 16 for deflecting a lowermost piece of material 15 contained in a hopper 12; a separator foot 25 for segregating the deflected piece from the hopper 12; a monitoring means 40 for determining whether only the lowermost piece 15 was, in fact, deflected; and, a gripper arm 18 for extracting the lowermost piece 15 and depositing the same on the conveyor 30. In one embodiment, the monitoring means 40 comprises an infrared source 29 which directs a signal to a sensor 27 mounted in the separator foot 25.
