Abstract
In a computer-controlled adhesive-applying apparatus an adhesive applicator device (20) is guided along a desired path in respect of three axes according to a programmed instruction instruction in the form of digitized co-ordinate axis values, said device comprising a nozzle (384) having a ball (392) by which the flow of adhesive is controlled and which also, by engagement with the work, determines the heightwise position of the device, together with a brush assembly (398) comprising a set of bristles (404) secured to the nozzle housing (384) and surrounding it, with ends of the bristles projecting beyond the end face (384a) of the housing and ball. The nozzle housing (384) and brush assembly (398) are mounted for rotation whereby adhesive supplied via the nozzle is spread on the workpiece surface. In addition, the nozzle housing (384) and brush assembly (398) can 'float' to accommodate irregularities in the heightwise contour of the workpiece surface. Means (200, 202, and 406 to 420) is also provided for tilting the device in order to maintain its axis perpendicular to the surface portion on which it is operating.
