Patent ID: 8082967

Claim:
Device for positioning a tubular label at a pre-established height from a bottle bottom in a rotating labelling machine of a type equipped with a tubular label winding drum around which the tubular label is formed, and adapted to support the bottle to be labelled on an upper base, said drum being able to vertically translate in order to take the bottle inside the formed tubular label, the device providing stopper members of a lower label edge; said stopper members being placed in a semi-circle at a pre-established height from the bottle bottom when the bottle is housed on the tubular label winding drum, the semi-circle diameter having to be such as to allow the vertical bottle translation during a bottle transfer step into the formed tubular label and to guarantee an elastic adaptation condition to the external and variable bottle surfaces, the stopper members of the lower label edge comprising a plurality of small vertical walls arranged as a semi-circle on a collar adapted to be secured to the upper base of the winding drum, the small vertical walls elastically adhering on the top to the external surface of the bottle to create a stop on which the lower label edge abut; the small vertical walls arranged as a semi-circle being suitable for a lateral extraction of the bottle.
