Powder spray coating installation - vertically displaces spray head within spray booth relative to coated items fed in curved path

摘要

At least one spray head (2) is contained within a spray booth (4) having at least one vertical slit (10) in one sidewall (12), via which the items (8) to be coated are fed to and from the spray booth (4). These items (8) are fed along a curved path of more than 180 degrees around the spray head (2), with a motor allowing vertical movement of the spray head (2) relative to the coated items. The motor lies outside and beneath the spray booth (4), with a coupling arm (16) projecting through the vertical slit (10) and aligned with an open section of the curved path. The spray device (2) is supported at the centre of the latter. ADVANTAGE - Allows reduced booth height and rapid colour changing.
