Abstract: An improved horizontal labeling machine comprises a shrinkable film drum, a tension device, a shrinkable film guide device, a movable base, a cutting device, a high-speed wheel, a conveying wheel, a feeding device, a conveying groove, and a thermal shrinking device. The packing object is placed horizontally in the feeding device while the shrinkable film is sent to a central guide pillar by a shrinkable film conveying device. The shrinkable film is spread out for the cutting by the cutting device, and the shrinkable film is sent to the conveying wheel by the high-speed wheel and then wrapped onto the packing object. The wrapped packing object is sent to the conveying groove and then to the thermal shrinking device for thermal shrinking. Such arrangement attains the effect of wrapping a shrinkable film onto the outer surface of a packing object.
