  • Patent number: 6209430
    Abstract: The present invention provides a method and an apparatus for forming a continuous web from a block of material. The block material has a base and a central axis extending generally orthogonally from the base. The apparatus preferably comprises a bath including a fluid into which the block of material can be at least partially submersed. Further, the apparatus preferably includes means for rotating the block about the central axis, a cutting device and means for linearly decreasing the predetermined distance of the cutting blade from the central axis. The cutting device is preferably positioned so as to make a cut into the block at a predetermined distance from the central axis, the cut being generally parallel to the central axis of the block. The material cut form the block preferably forms a continuous web.

  • Patent number: 5167897
    Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration.

  • Patent number: 4937088
    Abstract: A method of and apparatus for extracting the meat section and juice from a fruit while minimizing the amount of undesirable flavor components, e.g. peel oil, released from the fruit's peel. In one embodiment of the present invention, whole fruits are fed into a single station extraction apparatus that first cuts a equatorial groove in the fruit's peel while the fruit is rotated. A semicircular coring blade is then inserted into the groove and rotated 360.degree. which severs a spherical chunk of fruit meat from the peel. The small amount of fruit meat remaining on the peel's inner surface is then preferably extracted with a reaming element or fluid jet nozzle. In other particularly preferred embodiments, the grooving, coring, and reaming component mechanisms are incorporated into an indexing turret apparatus and a high-speed continuous motion turret apparatus.

  • Patent number: 4885182
    Abstract: A method of and apparatus for extracting the fruit meat section of a fruit, and subsequently separating and removing the sectional membranes and seeds from the fruit meat section to produce free juice and an abundance of unruptured juice sacs. In one embodiment of the present invention, whole fruits are fed into a dual turret extraction apparatus that includes a plurality of matched resilient cups for holding the fruit. After the fruit is cut in half, the halves are indexed through successive coring and reaming stations. The coring station includes a coring element that cleanly extracts a hemisperical section of fruit meat from the peel. The reaming station includes a reaming element that gently removes any fruit meat remaining within the peel. The fruit meat sections are then fed into rag separator apparatus that uses a rotating screen drum and a counterrotating shaft having striker bars projecting radially therefrom to strip the juice sacs from the sectional membranes.
