    Abstract: A rotary knife fixture for cutting vegetable products such as raw potatoes into spiral shapes. The knife fixture includes a ring-shaped blade holder driven rotatably within a hydraulic product flow path. The blade holder includes at least one cutting blade, wherein the blade is twisted from a generally longitudinally aligned center axis outwardly in opposite circumferential directions with a sharpened leading edge set at a desired pitch angle. By controlling the pitch angle of the blade in relation to the blade rotational speed and velocity at which the potato travels along the hydraulic flow path, the resultant spiral cut shape is selected. By using multiple cutting blades at known axially spaced positions and selecting the angular position of each cutting blade in succession, the number of spiral shapes cut from each potato is selected. The blades can have a nontextured straight-cut edge, or a textured crinkle-cut edge, or a combination.

The second set of knives then cuts the slab into a scoop shaped potato piece emulating a portion of a cut stalk of celery.

  • Patent number: 6681670
    Abstract: A movable water jet edge trimmer has an integral trim chute attached to a cutting support plate for the trimmer. The support plate has a cutting aperture and a series of suction apertures located inboard of the outside edge of the travelling web for supporting the web against the support plate as a water jet passes out through the cutting aperture away from the support plate and through the web. The support plate has a curved surface located downstream and outboard of the cutting aperture which curves into a trim chute opening of a trim chute. Negative pressure is applied from the trim chute to the trim chute opening to draw any strip of material cut from the edge of the web over the curved surface and into the trim chute.

  • Patent number: 6619834
    Abstract: Integrated in the mixing head of a polyurethane apparatus for producing a mixture stream of chemically reactive plastic components, is a cutting arrangement by which natural fibers or fiber strands of soft-elastic and tough consistency can be drawn from a continuous strand and, after cutting into fiber pieces of given length, can be introduced into the mixture stream. The cutting arrangement includes an inner guide tube which receives a fiber strand, drawn from a continuous fiber strand by two feed rollers, and fed via the guide tube and an outer support tube to rotating knife elements. By subjecting the guide tube to a vacuum and applying a compressed gas stream to the end of the outer support tube, the soft-elastic fiber strand is held straight in a manner which is optimal for the cutting process. The cut fiber pieces are introduced together with the gas stream into the mixture stream of chemically reactive plastic components.

  • Patent number: 6457393
    Abstract: An improved hydraulic cutting system is provided for cutting a succession of vegetable products or the like particularly such as potatoes into elongated strips, wherein the cutting system includes a deceleration conduit designed for decelerating cut product strips substantially without flow stream turbulence to reduce or eliminate strip breakage. The cutting system utilizes a propelling fluid flow stream to propel the products with substantial velocity into and through cutting engagement with knife elements of a so-called water knife fixture mounted along the length of a fluid flow passage. An improved deceleration conduit defines a continuation of the fluid flow passage at a downstream side of the water knife, and has a tapered shape which expands in cross section relative to a conduit centerline at an angle not exceeding 9° and preferably on the order of about 2° to about 3°.
