Abstract
A die for the manufacture of tray like sections has a member with a plurality of slots arranged to accommodate a variety of required gap dimensions. The slots are arranged in a pattern which consists of two sections each of which extends from a common datum in opposite directions along the length of the die. The first or integer section is of arbitrary length and contains slots spaced equally apart from each other a convenient value or metric. The distance between the right edge of the slot and the datum is equal to the metric value. The second section or vernier section contains slots with a different spacing pattern depending on the degree of precision required of the vernier. These slots are spaced incrementally from the datum by a value equal to a multiple of the metric plus a fractional value of the metric. This arrangement permits the accommodation of various tray sizes larger than a minimum size as dictated by die design. In operation, after two opposed side walls of a tray are formed, the outside dimension of the side wall is measured and the fractional part of the measurement used to determine the particular vernier slot to be used. With the correct vernier slot chosen for one side wall, a slot in the integer section automatically lines up with the other tray side wall.
