Method and device for producing sleeve-like labels

A device for producing a sleeve-like label, comprising a feeder, designed to feed to at least one forming spindle a portion of heat-shrink film, and means for wrapping said portion of heat-shrink film around the lateral surface of said forming spindle, said wrapping means being designed to provide a region of overlap between a first longitudinal end of said portion of heat-shrink film in contact with said forming spindle and the second longitudinal end of said portion of heat-shrink film, further comprising means for detecting the angular position of a free edge of said second longitudinal end of said portion of film wrapped around said forming spindle with respect to an absolute reference system that is jointly connected to said forming spindle, means being provided for the relative movement of said overlap region with respect to a region affected by the action of sealing means which are adapted to form a connecting portion at said overlap region, said relative movement means being adapted to move said free edge detected by said detection means to a preset position in order to provide said connecting portion at a preset distance with respect to said free edge, means being further provided for transferring said sleeve-like label from said forming spindle to a container to be labeled.

The device according to claim II, wherein said relative movement means comprise an apparatus for moving said sealing means in order to move said region affected by the action of said sealing means with respect to said overlap region.
