Sleeve machine

Printed shrink sleeves for decorating plastic or glass bottles, offer an effective medium for advertising purposes and additional protection. The flat film is unwound and runs through a bufferstack and is then pulled over a mandrel to form a tube. The sleeve is cut to size by knives in the cutting unit. The sleeve is then pushed down over the container and shrunk to fit the container contour in a heat tunnel. Static electricity may cause the film to stick to the mandrel or, once cut, the sleeve is not properly positioned on the container. Anti static bars placed at the indicated position assure a correct functioning of the machine.
