Abstract
An apparatus and method for interleaving a carrier sheet with sliced food products, such as bacon strips, has a supply conveyor for continuously conveying products with spacings that may be random or non-uniform, a delivery section to a drop-off point, a detector for detecting the position of each product from the drop-off point, a sheet supply source, an indexing conveyor for moving the carrier sheet to receive products at the drop-off point in timed relation to arrival of the products, a counter for counting down the arrival of each product to the drop-off point, and a programmable controller for controlling the advance of the carrier sheet to the drop-off point and incrementally thereafter to receive successive products in timed relation thereon. The preferred embodiment draws and cuts each carrier sheet from a supply paper roll. The indexing conveyor has a perforated belt and holds the carrier sheet on the belt by vacuum pressure. Multiple interleaver lines can be set up in side to side relation. A stacking mechanism has a reciprocating, telescoping conveyor for depositing successive product-laden sheets on a stack, and an elevator for adjusting the height of the stack below the telescoping conveyor.
