  • Patent number: 4230519
    Abstract: An apparatus for applying strips of tape around objects positioned adjacent the apparatus. A pair of tape holding reels are supported for movement in a path extending around the position occupied by the object. A tape end is applied to a surface of the object, and drive means are then operated for moving the tape reels around the object. The tape is thereby unreeled and automatically applied to the object surface. At the end of the track, or other means defining the path, severing means are utilized for separating a severed end from a reel whereby this severed end can be attached to an object surface to thereby complete the tape applying operation. The respective reels are inverted relative to each other with one reel being utilized for application of tape during movement of the reels in one direction and with the other reel being utilized for application of tape during movement in the opposite direction.

  • Patent number: 4178739
    Abstract: A construction for applying tape around the perimeter of an object wherein a supply of the tape is provided on a spool. An end of the tape is clamped, and the spool is then transported around the object with the tape then unreeling and being pressed into engagement with the object. Independently driven roller means are mounted for movement back and forth over one surface of the object, these roller means pressing respective tape ends onto the surface in overlapping relationship. This action is synchronized with clamping and severing action to prepare the system for a succeeding operation. The object to be taped is moved into position by means of a conveyor and a vertical lift. Stop means control the extent of movement of the lift, and this feature combined with the tape-applying mechanism makes the construction operable for a wide range of sizes of objects to be taped.
