DEFINITION

Classification: 100/155

(under subclass 144) Apparatus in which the material is compressed between bodies having pressure surfaces and at least one of bodies has a continuous pressure surface which rotates circularly about an axis with respect to the material and successive portions of the surface engage the material in rolling contact therewith.

(1) Note. Rolling mills for plastically shaping or bending metal are generally classified in Class 72, Metal Deforming.

A number of the classified characteristics are similar to or parallel those set forth in subclasses indented hereunder. Class 72 should be investigated in any case involving roll type press, especially in metal shaping.

SEE OR SEARCH THIS CLASS, SUBCLASS:

86, for presses which have additional treatment of the material in which such additional treatment involves winding a sheet, web, or strand upon a mandrel with pressure exerted by an opposed roll.

89, for presses which additionally treat the material to change their physical characteristic in which the additional treating involves winding a web, sheet or strand within a cage of pressure rolls.

121, for presses having drain means for expressing liquid through a pressure surface in which the pressure surface is on a roll. 153, for presses in which a roll and an endless belt are the opposing pressing members.

12, Boot and Shoe Making,

65, for toe and heel stiffener forming machines which mold the material between rolls or between a roll and a fixed form, the roll being rotated to feed the blank through.

15, Brushing, Scrubbing, and General Cleaning,

262, for mop wringers employing one or more pressure rollers for squeezing moisture from the mop.

38, Textiles: Ironing or Smoothing,

44+, for smoothing machines of the roller pressure type, and, subclasses 100+, for smoothing instruments consisting of rolls or rollers.

65, Glass Manufacturing,

253, for a glass sheet or strip rolling means; see the "Search Notes" thereunder.

68, Textiles: Fluid Treating Apparatus,

22, for textile treating machines combined with squeezing means of the roller type to extract liquid from the textile subsequent to the liquid treatment, subclasses 97+, for machines in which a textile is squeezed while subjected to a liquid and which embody a roll which rolls over a textile, or squeezing machines wherein the textiles are carried by said roll into and between the roll and a cooperating squeezing element and, subclasses 244+, for wringers for removing liquid from textile material where the wringer is of the roller type.

69, Leather Manufactures,

42+, for apparatus for the treatment of leather by the use of a tool which is positively rotated upon its axis during contact with the leather and the leather during treatment with the rotating tool is supported by a cylindrical roll.

72, Metal Deforming, appropriate subclasses. See (1) Note above.

83, Cutting,

284+, for a flying cutter, and, subclasses 509+, for a cutting tool pair comprising a rotatable anvil.

99, Foods and Beverages: Apparatus,

457, 462+, and 464, for revolving surfaces that treat dairy food; subclasses 557+, for a roller or belt contacting another member to press seeds from food, subclass 575, for adjacent surfaces that separate the shell from food, one surface of which rotates, and, subclass 625, for relative moving means that cooperate to remove the skin of food.

101, Printing,

3.1+, appropriate subclasses entitled "rolling contact" for embossing or penetrating printing machines, subclasses 22+, for rolling contact embossing machines and subclasses 216+, for machines for printing by exerting a rolling contact upon the printing surface and the surface to be printed upon in which the work is engaged in rolling contact between the peripheries of rotating members.

131, Tobacco,

27.1+, for cigar and cigarette making machines having cooperating surfaces which rotate about the tobacco to form a cigar or cigarette, place a wrapper thereon, or perform analogous operations, subclass 56, for cigar and cigarette making machines having cooperating rolling surfaces in which the cooperating rolling surfaces comprise a plurality of rollers, subclasses 84.1+ for cigar and cigarette making machines which mold or form the tobacco and shape it into a continuous rod of tobacco of indefinite length, and subclasses 116+, for plug or compressed tobacco shape making machines wherein the tobacco is molded into a sheet of indefinite length from which the plugs may be separated. 144, Woodworking,

255, for a woodbending machine wherein a rotating roller forces the wood against a yielding or an unyielding roller, a

belt, or a shoe to crimp the wood without securing it to a former.

164, Metal Founding,

428, for roll couple, metal casting means.

222, Dispensing,

281, for containers with a discharge assistant such containers having a single outlet formed by plural discharge assistants where the discharge assistants are parallel rolls.

226, Advancing Material of Indeterminate Length, appropriate subclasses, for methods of, and apparatus for, feeding material without utilizing the leading or trailing ends to effect movement of the material.
