Patent number: 4576339Abstract: An apparatus for cutting scrap tires and other waste products is disclosed. The apparatus includes a frame having a cylindrical anvil roll rotatably mounted therein. A blade roll is also mounted in the frame for rotation about an axis parallel to the rotational axis of the anvil roll, and a plurality of axially spaced roller blades of predetermined diameter are fixed to the blade roll and rotatable therewith. The blade roll is also provided with a pair of axially spaced thrust wheels, with the thrust wheels being positioned outboard of the blades and being equal to or slightly greater in diameter than the predetermined diameter of the blades. Driving means are provided in the apparatus for rotating the anvil roll and the blade roll in opposite directions in such a manner that scrap tires fed to the rolls will be drawn inwardly into the nip formed between the rolls and will be cut between the blades and the anvil.Type: GrantFiled: May 10, 1983Date of Patent: March 18, 1986Assignee: Uniroyal, Inc.Inventors: Robert H.

Patent number: 4575125Abstract: An article (e.g., a tire, a package, a label) having upon a surface thereof one or more identifying words composed of a plurality of letters chosen from an alphabet of distinctive letters. The letters, when uninverted, are readily distinguishable from one another upon comparison of the characteristic features of one letter with those of the remaining letters in the alphabet. In the particular embodiment illustrated, twenty-four of the twenty-six letters in the alphabet are invertible and form, when inverted, either the same letters or other letters of the alphabet. This allows uninverted words or groups of words to be selectively composed from the letters, which words, when inverted, form either the same words as or different words from the uninverted words.Type: GrantFiled: December 19, 1983Date of Patent: March 11, 1986Assignee: Uniroyal, Inc.Inventor: Pierre J. Augier
