Abstract
The invention relates to a mandrel, a sleeving device and a method for sleeving containers. The mandrel is suspended in the sleeving device. The mandrel opens a foil to form sleeves. The foil is fed around the tubular outer surface of the mandrel. According to the invention the outer surface of the mandrel is formed by at least two separate mandrel bodies. At least one of the mandrel body is biased outwardly to increase the circumference of the outer surface. This circumference is automatically adapted to the current, instantaneous circumference of the foil fed around the mandrel.
Claims18
A mandrel configured to be suspended in a sleeving device for arranging sleeves around containers, the mandrel (i) configured to open a foil to form a sleeve and (ii) having a substantially tubular outer surface around which the foil is fed, the outer surface of the mandrel being formed by at least two separate mandrel bodies, wherein at least one mandrel body is biased outwardly to increase the circumference of the outer surface and wherein the at least one mandrel body biased outwardly is configured to be continuously adjusted to control the circumference of the outer surface during operation of the mandrel.
A method for feeding a foil over a mandrel for arranging sleeves around containers, the method comprising biasing an outer surface of the mandrel outwardly for tensioning the foil around the mandrel and continuiusly adjusting the outer surface of the mandrel in response to a varying inner circumference of the foil,
- wherein the foil is fed to the mandrel and over and around the outer surface of the mandrel, and
- the foil is cut into sleeves to be arranged around the containers.
