Abstract
A valved flow control dispenser including a slot nozzle through which molten thermoplastic material is dispensed onto a substrate. The slot nozzle includes a nozzle body within which there is a transverse cylindrical bore, which bore is intersected by two spaced radial openings. One of these openings is in fluid communication with a pressurized source of molten thermoplastic material, and the other opening is in fluid communication with a slotted discharge opening of the nozzle. A cylindrical flow control member having a groove provided in its exterior surface is rotatably mounted within the bore. This groove is of varying width and provides a flow path for molten thermoplastic material between the openings in the bore. By varying the rotatable orientation of the cylinder relative to the openings, the width of molten material dispensed from the slotted discharge openings of the nozzle may be varied.
