  • Patent number: 9486008
    Abstract: A system for trimming a lettuce head using a digital imaging system and cutting mechanism. The lettuce head is conveyed between a lower feed conveyor and an upper feed conveyor that is disposed a fixed distance over and substantially aligned with a lower feed conveyor. The digital imaging system is configured to capture an image of the lettuce head and determine a cutting profile using the image. The cutting mechanism is disposed over the lower feed conveyor and includes: a servo motor mechanically coupled to a drive shaft; an armature with a pivot end mounted to the drive shaft and a sweep end disposed a radial distance from the pivot end; a cutting nozzle, mounted to the sweep end of the armature, configured to trim the lettuce head; and servo-control circuitry configured to articulate the cutting nozzle through a cutting arc based on the cutting profile.

  • Patent number: 6217309
    Abstract: A sliced food product such as a cheese product or meat product having a design or figure cut or otherwise formed therein. In accordance with a preferred embodiment, the design or figure is cut entirely or substantially through the slice so that the design or figure may be removed from a surrounding peripheral portion of the slice. A method and apparatus for forming the figure or design are also disclosed. The preferred method and apparatus employ a rotary figure cutter which cuts entirely through the slice to outline a pattern or figure, and which cuts or penetrates partially through the slice to form details of the figure by embossing or indenting design components on the slice. The slice is preferably wrapped in film prior to the figure cutting operation, and the figure cutter performs its function without cutting or tearing the film wrap. The rotary figure cutter preferably comprises a pair of rotary dies between which each slice passes as the design is formed thereon.
