Abstract:
1. A method for producing sleeve-like labels, comprising: a step of feeding a portion of heat-shrink film to a forming spindle; a step of wrapping said portion of heat-shrink film around said forming spindle, a region of overlap being provided 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; a step of detecting the angular position of the free edge of said second longitudinal end of said portion of heat-shrink film wrapped around said forming spindle with respect to an absolute reference system that is jointly connected to said forming spindle; a step of relative movement of said overlap region with respect to the region of action of sealing means, which are adapted to provide a connecting portion at said overlap region, in order to move said free edge detected by said detection means into a preset position in order to provide said connecting portion at a preset distance with respect to said free edge; a step of sealing said first longitudinal end to said second longitudinal end in order to provide said connecting portion at said preset position with respect to said detected free edge; a step of transferring said sleeve-like label from said forming spindle toward a respective container to be labeled, wherein said step of relative movement of said overlap region is carried out by angularly moving said forming spindle with respect to said absolute reference system jointly connected to said forming spindle.
