  • Patent number: 6109421
    Abstract: A corn transfer and alignment mechanism for preparing ears for being sawn into cobbettes is provided. The ears are received by the transfer mechanism from a feed conveyor on which the ears are conveyed singularly with their tip ends first. The transfer station uses a transfer plate and stabilizer drum to reduce the forward momentum of the ears and align the tips of the ears against a guide plate. The aligned ears are then discharged onto a roller conveyor for presentation to trimming saws.

  • Patent number: 5938002
    Abstract: A dry shuffle feed apparatus is provided for use with produce for feeding produce in a predetermined timing pattern to processing equipment. One or more shuffle conveyors, each having multiple flights, are provided having an infeed chute and return chute. Produce enters the infeed chute and is fed onto the conveyor, the infeed chute having a multi-angulated surface to prevent bridging of the produce. A return chute extends upwardly alongside the conveyor from the infeed chute and returns excess produce to the infeed chute. The flights on each shuffle conveyor become narrower nearer the output end of the conveyor and overfed produce falls off the conveyor onto the return chute.
