An adjustable girth control for a tube former (16) in a packaging machine (10) for encapsulating individual rolls (14) or groups of rolls (14) in a film (18). The tube former (16) includes a forming body (46) which is shaped to envelop the product (14) passing therethrough and which has opposite adjustable forming elements (48, 50) with a variable gap (52) between them. The forming elements (48, 50) are shifted horizontally and vertically to vary the internal dimensions of the forming body (46) to ac- commodate rolls (14) of different diameters. The shifting of the forming elements (48, 50) can occur manually or automatically in response to the detection by a sensor (154) of the sizes of the incoming rolls (14).
Commande de circonférence réglable pour un forme-tube (16) dans une machine d'emballage (10) servant à envelopper des rouleaux individuels (14) ou des groupes de rouleaux (14) dans une pellicule (18). Le forme-tube (16) comprend un corps de formage (46) qui est façonné de manière à envelopper le produit (14) qui y passe et qui a des éléments de formage réglables (48, 50) opposés avec un écartement variable (52) entre eux. Les éléments de formage (48, 50) pivotent horizontalement et verticalement pour modifier les dimensions internes du corps de formage (46) de façon à s'adapter à des rouleaux (14) de diamètres différents. Le pivotement des éléments de formage (48, 50) peut se faire manuellement ou survenir automatiquement en réaction à la détection par un capteur (154) des dimensions des rouleaux (14) qui arrivent.
