Abstract
An adjustable girth control for the tube former in a packaging machine for encapsulating individual rolls or groups of rolls in a film. The tube former includes a forming body which is shaped to envelope the product passing therethrough and which has opposite adjustable forming elements with a variable gap between them. The forming elements are shifted horizontally and vertically to vary internal dimensions of the forming body to accommodate rolls of different diameters. Shifting can occur manually or automatically responsive to detection of the sizes of incoming rolls.
