Abstract
The following specification describes a method together with portable apparatus for forming on site test dummies of stacks of business forms to provide a facsimile of actual conditions under which the paper is imprinted. This is done by simultaneously manually perforating and crimping a stack of paper containing a desired number and type then aligning a plurality of serially arranged stacks in a web by means of a splicing jig to enable the simulation of an actual run. The portable apparatus includes a plate carrying perforating and crimping dies and punches together with the splicing jig. The punches are operated by a cam having a continuous surface engaged with a punch holder. The punches protrude from the holder by different distances so that they pierce the paper at different times to reduce the manual force required for operation.
