US 4,671,205 A · Apparatus for applying partial surface coatings

Abstract

Apparatus for applying partial surface coatings to textile substrates, particularly adhesive compounds in fixing inset technology. A cylinder rotatable about a cylindrical axis has inner and outer cylindrical surfaces with perforations extending through these surfaces. A coating head mounted inside the cylinder has a coating nozzle adjacent and facing the inner surface. The head includes a feed duct, a main duct extending from the feed duct and an opening chamber extending from the main duct. The opening chamber is bounded by two sealing lips adapted closely to the inside of the cylinder, supported by a mounting structure for the chamber and defining an outlet opening therebetween for controlling flow from the chamber. The structure has rods attached to the lips and adjustably coupled to the coating head to enable the opening to be adjusted in width.
