ABSTRACT:
A water scoring apparatus includes one or more needle assemblies adjustably carried upon a displaceable support bar transversely disposed atop a machine through which a sheet or web of paper is passed. A needle removably attached to a holder is in turn connected to a bracket joined to a mounting block on the support bar. The mounting block, bracket and holder all include adjustment mechanisms allowing for precise angular, vertical and transverse adjustment of the position of the needle tip with respect to the moving paper therebeneath. A pressurized source of liquid delivers fluid to a manifold on the support bar and which includes individual valves to regulate the flow of fluid to separate lines leading to the needles of each assembly.
