ABSTRACT:
A process for aligning at least two layers in an abutting relationship with each other comprises forming a plurality of sprocket openings in each of the layers for receiving a sprocket of diminishing diameters as the sprocket extends outwardly from a base, with the center axes of the sprocket openings in each layer being substantially alignable with one another, the diameter of the sprocket openings in an abutting layer for first receiving the sprocket being greater than the diameter of the sprocket openings in an abutted layer. This is followed by forming a plurality of reservoir openings in each of at least two of the layers and positioning the sprocket openings in the layers to correspond with one another and the reservoir openings in the layers to correspond with one another so that substantial alignment of the center axes of the corresponding sprocket openings in the layers effects substantial alignment of the center axes of the corresponding reservoir openings in the layers. Engaging the sprocket openings with the sprocket by inserting the end of the sprocket having the smallest diameter into the sprocket openings having the largest diameter in the layers and continuing through to the sprocket opening having the smallest diameter in the layers effects substantial alignment of the center axes of the corresponding sprocket openings and substantial alignment of the center axes of the corresponding reservoir openings in the layers. The invention also comprises apparatus-for performing this process.
