avoid excessive length of spray path to fabric substrate surface and the corresponding increase in size of shroud required for such the relative angle between the plane of the spray head discs the spray path and the plane of the fabric substrate should be greater than about 10 u00b0 preferably the center of the spray heads in straight line distance perpendicular from the substrate fabric should be from between about 6 34 to 24 34 in establishing a desired spray path fabric substrate path angular relation the fabric inlet and exit slots 46 48 in the shroud and guide rollers 28 30 may be appropriately relocated from their positions shown in fig1 to accommodate the particular fabric path and the desired relative angle between the discharge spray path and the plane of the fabric fig7 10 show a second embodiment of the present invention in which the applicator section of the invention is modified to provide relative positioning of the support housing and shroud enclosure of the applicator section like elements of the applicator section of the second embodiment to those of the embodiment shown in fig1 6 are identified by their prime numbers the applicator section 32 39 of fig7 10 is constructed with a shroud enclosure 82 communicating with the support housing 40 39 to permit relative adjustable positioning of the housing 40 39 and shroud 82 as seen in fig7 10 the housing and shroud enclosure are operatively interconnected by means of a continuous flexible member such as a pleated rubber sleeve 83 opposed ends of which are attached as by one or more clamp members 84 to the respective outer wall surfaces of the housing 40.
