Abstract: Plastic containers are given a coating of barrier or other coating material by being passed in close proximity to the lower edge of a plate curved downwardly. Liquid coating material is delivered to the back of the plate, to spread over it and fall as a curtain through which the article is passed, the article being rotated to present the whole of its recipient surface to the curtain. The articles may be tilted as they pass through the curtain.

Abstract: A packaging machine is described in which articles or groups of articles are wrapped in a sleeve of stretch-wrap material. The machine includes a sleeve feeding and cutting assembly for drawing the leading end portion from a roll of stretch-wrap tubing, for opening the leading end, and for severing the leading end portion from the remainder of the roll to form a sleeve. A gripping assembly grips the open leading end and draws the sleeve onto a pair of relatively movable stretching plates. The plates are movable apart to stretch the sleeve to a size greater than the article or group of articles that it is required to wrap. A pusher is arranged to push the article or group of articles into the stretched sleeve. A discharge assembly is arranged to draw the sleeve and article or articles in unison away from the stretching plates.
