Definitions

  • a strip of tape is would into a roll having smooth sides by passing the tape over a substantially frictionless surface immediately prior to the transfer of the tape onto the reel hub.
  • the frictionless surface is provided by air escaping from an air-permeable member, which member is constructed and arranged to function as a conventional contact roller.
  • a tube connected to a source of air under pressure is carried by a pivotally-mounted guide arm.
  • An airpermeable disc having opposed flanges secured thereto, is positionable between the flanges of a reel and is mechanically biased into engagement with the hub at a predetermined pressure determined by the setting of an adjustable weight carried by the guide arm.
  • the tape passes over the peripheral surface of the disc as it is wound onto the reel hub and the pressure exerted upon the tape convolutions eliminates air entrapment.
  • the flanges on the disc are spaced from the reel flanges, whereby normal wobble of the reel does not effect the tape winding operation.
  • An object of this invention is the provision of improved apparatus for winding a narrow, thin film into a smooth roll on a tape reel.
  • An object of this invention is the provision of apparatus for winding a thin film onto the hub of a reel having flanges, which apparatus includes means preventing entrapment of air between the convolutions of the film as it is being wound and means preventing an uneven winding of the tape due to normal wobble of the reel flanges.
  • An object of this invention is the provision of apparatus for winding a strip of film onto the hub of a reel, in which apparatus the film passes over the surface of an air-permeable member and onto the hub, said member being connected to a source of air under pressure and applying a mechanical pressure to the film as it is being wound on the hub.
  • the numerals l0 and 11 identify narrow strips of magnetic tape, which strips have been formed from a wide web of the material by a conventional continuous slitting machine and pass over an idler roll 12 and a pull roll 13. Adjacently disposed strips are directed to spaced winding stations of the machine where they are wound onto reels, each set of reels being mounted on a power driven mandrel.
  • the reels carried by a mandrel are spaced apart a distance corresponding to the thickness of the particular reels by spacer rings arranged so that the individual reels may slip'relative to the mandrel to maintain a substantially constant tension on the strip being wound thereon.
  • this strip passes around an idler roll 14 and over a guide roll 15 as it moves to the reel 16 having a hub 17 and flanges 18.
  • the end of the tube 21 carries a coupling 24 for connecting the tube to a source of air under pressure by means of a flexible hose.
  • Extending from the guide arm 22 is a threaded rod having a weight 25 threaded thereon, said weight being secured in a desired, fixed position by means of conventional lock nuts.
  • the guide arm 22 is pivotally-connected to a U-shaped block 26 which is secured in fixed position on the winding machine, said guide arm being rotatable about a pivot pin 27 in correspondence with the change in diameter of the tape roll on the reel.
  • the tube 21 communicates with the hollow interior of the air-permeable disc 20 which has thin, metal flanges 28 secured to the sides thereof.
  • the flanges 28 are spaced from the inner surfaces of the reel flanges 18 and the spacing between the flanges 28 is slightly greater than the width of the particular tape, as indicated by the letter W.
  • the end of the tape strip is attached to the reel hub, as by means of adhesive tape.
  • the end of the tape is inserted through a slot provided in the hub.
  • the reel is rotated on the mandrel, by hand, to move the first tape convolution underneath and somewhat beyond the airpermeable disc. Air under pressure is then applied to the tube 21 and the mandrel is power driven at a constant speed.
  • the flanges 28 prevent a side shifting of the outermost convolution due to wobble of the reel and the draw distance between the reel and the guide roll 15.
  • the air-permeable disc applies a predetermined down pressure on the tape to eliminate entrapped air which not only causes a lateral shifting of such convolution but, also, causes wearing of the tape as it is wound at high speeds. Further, the air escaping from the peripheral surface of the disc creates an air-bearing surface with a minimum coefticent of friction thereby eliminating excessive tape-tension problems and tape wear.
  • the apparatus has been described with reference to the winding of a strip of magnetized tape on a conventional tape reel having flanges, it will be apparent that the apparatus can also be used for the winding of other, thin films. Also, the apparatus is useful for winding magnetic tape into a roll for use on a three piece reel. in this case, the tape is wound on a core which is supported on a winding mandrel by a slip clutch.
  • the reel flanges are molded in two pieces, each piece having a hub portion substantially equal to the inner diameter of the core. The wound roll of tape is removed from the clutch and the hub portions of the reel flanges are inserted into the core and permanently secured thereto by means of a suitable cement.
  • LApparatus for winding a thin strip of material on a core carried by a rotatable mandrel which apparatus comprises,
  • a guide arm mounted for pivotal movement in the plane of the core
  • a tubular member secured to the guide arm and connectable to a source of air under pressure, an end portion of the tubular member extending from the guide arm,
  • an air-permeable member having an arcuate peripheral surface and secured to the said end portion of the tubular member, said air-permeable member having a hollow interior communicating with the interior of the tubular member,
  • e. means biasing said air-permeable member toward the said core to apply a predetermined pressure on the said strip of material as it is being wound.
  • Apparatus for winding a strip of magnetic tape on the hub of a reel having side flanges comprising,
  • a tube secured to the guide arm and connectable to a source of air under pressure, an end portion of said tube extending from the guide arm and between the flanges of the reel,
  • e. means biasing the air-permeable member into engagement with the said strip of tape as it is being wound on the reel hub.
