Abstract
Shredding devices and methods capable of cutting material, such as one or more pieces of media, into different-sized portions. In certain examples, a cross-cut shredding device comprises multiple blades, each having a plurality of blade tips disposed around the periphery of the blades. The blades tips may be unequally spaced to produce shredded pieces having varying lengths. In other examples, a cross-cut or strip-cut shredding device may comprise blades having varying spaces therebetween, which results in shredded pieces with varying widths. Varying the blade tip spacing, the blade width, and/or the blade spacing is advantageously used to produce shredded media of different sizes. Certain shredding devices are configured to produce smaller shredded pieces toward a middle portion of the material to increase the recombination time of shredded material.
