  • Patent number: 4949891
    Abstract: An apparatus for selectively feeding tape having label patterns printed on it at one of two different speeds to maintain alignment of the label patterns with a downstream device such as a cutter for severing the tape between label patterns. Marks on the tape associated with the individual label patterns are monitored by a sensor to detect misalignment of the tape. The tape is fed between a driven feed drum and a spring biased pressure drum. The feed drum is mounted on a main shaft. A drive shaft extends parallel to the main shaft. A pair of gears are mounted on each of the shafts and each gear meshes with one of the gears on the other shaft to form two separate power transmission paths. The sizes of the gears are selected so that the gear ratios of the two power transmission paths are different. The gears on the main shaft are selectively fixed to the main shaft for rotation with it by electromagnetic clutches controlled by the sensor.
