Abstract
Knitted netting is applied to products in a machine. A chute receives products serially through a receiving end, as from a conveyor, and discharges them serially into netting preferably rucked on the chute. As each product arrives at the product receiver, voiders operate to form a rope section of the netting behind the product, at the chute's discharge end. The clipper also clips the netting, to complete the netting of the product, and clips to create the starting end of the next netted product. A netting handle former operates to loop the rope section behind the product, before clipping, to form a looped handle for a product in the rope section of the netting. The netting that is clipped behind the products is the netting formed into the loops, and thus, the clips that are put on by the clipper secure the loops in their size and condition. The product receiver is preferably a discharge tray, and product guides on the tray straighten the product, to align it for netting, and also co-operate with the voiders to help tighten the product packaging. The clipper is also preferably uniquely structured in its clip rails to contribute to tighter packaging. The clip rails are paired on one …
