ABSTRACT:
A steel rule die for cutting cloth and synthetic materials. The cutting die includes a primary substrate and a plurality of cutting units that are removably attachable to the substrate in such a manner that they are easy to adjust, remove and replace. The cutting units include secondary substrates with lengths of steel rule attached to them. The cutting units are secured to the primary substrate. Each steel rule is fixedly attached to a secondary substrate that is substantially harder than the primary substrate. The secondary substrate distributes the cutting load applied to the rule over a large surface area on the primary substrate to prevent the cutting units from diving into the soft primary substrate. Substantially the entire length of the steel rule is supported by the secondary substrate, thereby yielding a rigid cutting unit that is not susceptible to deformation. The cutting units can also include bent internal cutting sections and adjustable and removable internal cutting units that allow scrap material to flow through the cutting die. Moreover, the secondary substrates can include openings for reducing the overall weight of the die without effecting the support it provides to the steel rule.
