ABSTRACT:
Disclosed herein is a band wrapping machine which, using one web of heat-sealing material, attends to the packaging of a plurality of boxes or products. The machine is equipped with one roll of the said material that is placed above the horizontal packaging surface and extends vertically up to and across a first horizontal roller positioned beneath the said surface, the axis of this being parallel to that of the said roll and parallel to the devices for cutting and welding the web, that is to say, perpendicular to the horizontal direction in which the parcels of boxes are infed, the said first roller being movable vertically under the action of the pull exerted by the web since this, downstream of the said first roller, is inserted in between a pair of drive rollers that are only able to move in the direction through which the web is unwound from the roll.
