Abstract: For use in a web-handling apparatus, a cylinder module accumulates and de-accumulates web in a controlled manner. A frame supports first and second parallel main cylinders. The first cylinder rotates continuously, while the second cylinder operates in a non-uniform manner. A third main cylinder remains parallel with the first and second axes while moving perpendicular to those axes. The web passes around the first cylinder through the first nip, thence to and around the periphery of the third cylinder, thence to and partially around the periphery of the second cylinder and through the second nip. The web spans from the third cylinder are substantially parallel. An endless belt associated with each end of the third cylinder ensures that the third cylinder occupies an axis location and a rotational position which substantially control the web stress as the web passes through the cylinders.

Abstract: A method and apparatus to reduce ripple in the signal produced by a transducer attached to a dancer roll, or web accumulator, where cyclic web motion is present. Two transducers are used, one to produce a dancer roll position signal, and another, responsive to the cyclic web drive, to produce a signal corresponding to the ripple component of the dancer roll position signal. An adder combines both signals to generate a third, ripple free signal indicative of the average dancer roll position in the web accumulator. This ripple free signal may be used to control the web speed.

Abstract: A prefeeder drive for a sheet of material positioned on the input side of a standard incremental type sheet feeder for a forming press and which has drive rolls that move a sheet of material through a lubrication bath and toward the press. The sheet is driven to form an upright or overhead loop prior to entry of the sheet into the main, incremental feeder. The drive comprises a pair of rolls which are driven in response to a feedback control system sensing the size of the overhead loop so that the loop size is maintained within a desired range to insure satisfactory feeding of the sheet material into the main feeder and thence into the press. The overhead or free standing loop substantially reduces the inertia of the material that the main feeder has to overcome when feeding an increment of sheet stock into the press, and thus makes the feeding of the material more reliable with less likelihood of misfeeds.

Abstract: An apparatus for scanning a magnetic video tape includes a drum and a rotatable magnetic head. A freely rotatable roller and a loosening mechanism are positioned on opposite sides of the tape. When the tape stops, the loosening mechanism is driven toward the roller and thus engages the tape between the loosening mechanism and the roller. Rotation of the loosening mechanism then loosens the tape.
