A method for cutting vehicle tires and the like is disclosed together with apparatus for practicing the method comprising a first plurality of cutting discs axially spaced from each other along a first shaft and a second plurality of cutting discs axially spaced from each other along a second shaft parallel to the first. The thickness and spacing of the cutting discs along their respective shafts and the spacing of the shafts with respect to each other is such that the cutting discs of each plurality intermesh with those of the other plurality with the overlapping side surfaces of the discs substantially in contact to provide a scissor like cutting action and the free peripheral surfaces of the discs of each plurality are spaced from the shaft of the other plurality a distance sufficient to allow passage of the cut slices of the vehicle tires or the like. Various embodiments including means for enhancing feeding action and for recycling the cut slices are described.
Apparatus for cutting fiber reinforced resilient materials such as vehicle tires and the like into small parts comprising a pair of generally cylindrical cutting rolls mounted for rotation with their axes parallel and each including a plurality of axially spaced radially extending ribs forming troughs therebetween with said ribs of each roll meshing with said ribs of the other roll, each of said ribs having planar sides with a side of each rib of one roll overlapping and spaced less than about .030 inch from a side of an adjacent rib of the other roll, and each of said ribs having a plurality of radially extending protrusions spaced from each other about the outer periphery thereof, the spacing between the axes of said rolls and the dimensions of said ribs being such that said ribs of said rolls overlap each other by an amount which is less than the maximum thickness of said fiber reinforced resilient material as received between said rolls.
