Apparatus and method for obtaining labels

A method for obtaining “shrink sleeve” labels, comprising:

• providing a carousel rotatable about an axis,
• providing the carousel peripherally with a plurality of spindles;
• winding portions of plastic film around the spindles so that opposite edges of said portions adherently overlap one another at a sealing point position on the respective spindles;
• providing a sealing device cooperating with said spindles for sealing said overlapped opposite edges of said portions for obtaining said “shrink sleeve” labels, said sealing device comprising a laser device;
• using said laser device, emitting a laser beam on said opposite edges overlapped on one another on said spindles;
• arranging said laser device outside the carousel;
• and
• controlling movement of the laser beam to follow the sealing point position using a scanner optic as it rotates about the axis of the carousel relative to the laser device.

Method for obtaining “shrink sleeve” labels, comprising:

• providing a carousel that is provided peripherally with a plurality of spindles configured for being wound by portions of plastic film;
• providing each spindle of said plurality of spindles with a side surface comprising zones arranged at distances from a longitudinal axis of said spindle that are different from one another and a notch extending parallel to said longitudinal axis;
• defining a sealing section provided along a concave portion of the notch to adherently receive inside the notch opposite edges of said portion to be sealed together, so that said opposite edges overlap one another;
• and
• providing a sealing device being cooperating with said spindles for sealing said opposite edges for obtaining said “shrink sleeve” labels, said sealing device comprising a laser device to direct a laser beam towards the sealing section within the concave portion of the notch to seal the opposite edges.
