Patent ID: 8293047

Claim:
A method for containers, comprising the steps of: positioning at least one container ( 100 ) at a time in a labeling position, positioning at least one heat-shrinkable label ( 200 ) in a form of an annular band below each container located in a labeling position, and raising the label ( 200 ) such as to insert the label ( 200 ) from below on the at least one container ( 100 ) in a labeling position, positioning dispensing device ( 51 , 53 ), said dispensing device comprising a plurality of columns and at least one nozzle associated with each of said plurality of columns, for dispensing a hot fluid at the labeling position, such that once a position of maximum raising has been reached, the columns are inserted in empty spaces comprised between the containers in the labeling position and the dispensing device is stationary with respect to the label ( 200 ) which is displaced in order to be positioned below the container ( 100 ) in a labeling position, and performing, by means of the dispensing device ( 51 , 53 ), heat shrinkage of at least a portion of the label ( 200 ) when the label is inserted on the at least one container ( 100 ) which is in the labeling position, in which the portion extends over a whole axial development of the label ( 200 ), wherein the heat shrinkage of the portion of the label ( 200 ) on the container ( 100 ) in the labeling position is obtained by vertically moving the dispenser means ( 51 , 53 ) during dispensing of the hot fluid, such as to invest the label ( 200 ) over the whole axial development thereof.
