By Change Of Effective Shape Of Driving Or Driven Surface Of Element Of Work-feed Mechanism Patents (Class 83/246)
  • Patent number: 4664005
    Abstract: A device for automatically dispensing labels from a tape comprises a drive shaft and means for driving the tape intermittently from the drive shaft. These drive means comprise a tape feed shaft and a tape feed gearwheel coupled to this shaft. The device also comprises means for actuating the cutter from the drive shaft when the tape is stopped, in the form of a cutter actuator shaft and a cutter actuator gearwheel coupled to this shaft. A cylindrical drive member is coupled to the drive shaft and at least one toothed sector on the cylindrical drive member meshes with the tape feed and cutter actuator gearwheels in such a way that these gearwheels are driven one after the other.

  • Patent number: 4619165
    Abstract: An apparatus with a cutting device for cutting-off pieces of a wire comb binding material for binding packs of sheets with marginal perforation. The pieces to be cut-off from the material shall have an entire number of teeth. The apparatus has a guide and a conveying wheel for the material. A brake or a catch provides for the pitch-correct cutting of the material. An adjusting device for adjusting the conveying length is provided in the drive connection to the conveying wheel. For this purpose a sector gear wheel comprises partial sector gear wheels. These are rotatable and capable of being fixed with respect to one another. Alternatively, an eccent arrangement may be used for adjusting the conveying length. The radial eccenter distance of the arrangement is adjustable. A chain driven thereby is itself driving a chain wheel, which on its turn drives a catch wheel for driving the conveying wheel.

  • Patent number: 4305317
    Abstract: A feed and cutting device for dividing a continuous web into portions is described. The device comprises along a feed plane, guiding device for the web comprising a pair of mutually tangential rollers, apparatus for feeding the web along said plane and a device for cutting the web into portions. The main feature of the device is that at least one of the guide rollers is mounted on a shaft coaxial thereto and rotating with continuous motion, and is connected to the shaft by a self-locking device which prohibits any discordant relative rotation between the roller and the shaft but which allows idle rotation of the roller on the shaft at an angular speed exceeding the angular speed of the shaft, the angular speed of the shaft being close to but less than the angular speed transmitted to the respective roller by the feed device by way of said web.
