Work-feed Element Contacts And Moves With Work Patents (Class 83/276)
  • Patent number: 4058039
    Abstract: A method and machine adapted to removed baked waffles from a succession of waffle irons on a feed conveyor, trim the waffles so removed into a regular peripheral configuration, and transfer those waffles in succession onto a transfer conveyor. The feed conveyor is adapted to convey a series of successive waffle irons, with baked waffles thereon, from an oven to a transfer location. A vacuum head of novel structure is provided at the transfer location to move cyclically in a machine direction of the feed conveyor between an upstream and a downstream location, the vacuum head being raised and lowered during that limited motion path to pick up waffles by vacuum from successive waffle irons without stopping the conveyor. The vacuum head is also movable in the cross machine direction of the feed conveyor between the feed conveyor and a transfer conveyor.
