摘要： The present invention relates to an improved taping apparatus which comprises a cam mechanism and a belt member disposed around the circumferential surface of the cam mechanism, whereby the belt member rotating along the periphery of the cam mechanism can continuously apply a tape around a peripheral surface of the object, in particular in the shape of a closed-loop, while the object is disposed within the central space of the cam mechanism, so that the tape can be automatically applied around the object and the productivity can be improved. The taping apparatus is characterized in that it comprise an annular cam mechanism supported in both sides by frames and having an entrance formed through a part of the cam mechanism, through which entrance the object to be taped can be introduced into the central space of the cam mechanism; an annular belt member loosely encompassing the peripheral surface of the cam mechanism and extended across the entrance, so that when the object is introduced into the central space of the cam mechanism through the entrance, the belt member can be stretched and bring the tape into tight contact with the surface of the object; and means for rotating the cam mechanism so that the belt member can continuously contact with the peripheral surface of the object and simultaneously apply the tape around the object.
