Nozzle bar with adjustable pattern

摘要

A nozzle bar apparatus for applying a pattern of a viscous material upon a portion of a substrate where the apparatus is adjustable to vary the length, width and position of the pattern relative to the substrate including a nozzle member for selectively dispensing the material in a predetermined pattern and frequency including at least one material flow path through the nozzle member, the flow path having a first end forming an outlet facing the substrate for dispensing the material to the substrate and a second end in operable communication with a material supply for providing a flow of viscous material, the outlet having a predetermined range defining a width of the pattern, the nozzle member being activated for a selected period of time to control a length of the pattern and including a pattern control mechanism for selectively varying the width as well as the position of the pattern anywhere across the range of the outlet.
