Definitions

  • a device for dispensing paper or like material from a roll of such material which includes roller means mounted for rotation inside a loose roll of material, and for rotating the roll when it is tightened onto the roller means as a result of a pull on the material, the roller means tending subsequently to loosen the tightened roll, and means for applying a frictional drag to the inner end of the material thereby tending to re-tighten the roll onto the roller as a result of the pull on the material.
  • This invention relates to device-s for dispensing paper or like materail from a roll of such material, and is concerned, more particularly, with such devices for use in situations where when the material is required it must be dispensed suddenly and at high speed.
  • One particular application where such a dispensing device is required is in ultra violet recording devices in which a number of separate traces are recorded upon paper whch is sensitive to ultraviolet light, but relatively insensitive to daylight thereby elminating the need for a subsequent developing process after recording.
  • Each trace is produced by a separate galvanometer having a mirror to reflect light from an ultra-violet source on to the sensitized paper.
  • the sensitized paper is passed through the recording device at a sufficiently high speed it is possible to resolve on each trace each cycle of movement of the galvanometer, but as the frequency response of the galvanometer is increased due to advances in galvanometer design it becomes necessary to pass the sensitized paper through the device at higher and higher speeds to achieve resolution of each cycle if advantage is to be taken of the improvement in frequency response.
  • Modern galvanometers may have a frequency response of up to kc./s. so that if each cycle of the trace is to occupy which is considered adequate for subsequent visual examination of the trace, then it is necessary to move the paper at a speed of 1,000 inches per second.
  • the present invention consists in a device for dispensing paper or like material from a roll of such material, which includes roller means mounted for rotation inside a loose roll of material, and for rotating the roll when it is tightened on to the roller means as a result of a pull on the material, the roller tending subsequently to loosen the tightened roll, and means for applying a frictional drag to the inner end of the material whereby tending to re-tighten the roll onto the roller as a result of the pull on the material.
  • FIGURE 1 is a view which shows diagrammatically a device for dispensing paper according to the present invention.
  • FIGURE 2 is a section through the device of FIGURE 1 showing diagrammatically a roll of paper thereon.
  • FIGS. 1 and R2 show diagrammatically a device for dispensing a web of paper from a roll to a pair of spring loaded pinch rollers R1 and R2, provided in recording apparatus RA, the left hand side of FIGURE 1 being shown in axial section.
  • the device includes a central roller 1 fixed on a driven shaft 2 mounted for rotation on a framework 3. Freely mounted on the shaft 2 are two sleeves 4 having flanges 5 and the two sleeves are coupled for rotation in uni-son by means of gear wheels 6 mounted on a common shaft 7 and engaging gear teeth provided on the periphery of each flange 5. Rotation of the sleeves relative to the framework 3 can be prevented by means of a removable pin 8 passing through apertures in the framework and one sleeve.
  • Each sleeve 4 carries a spring clip 9 and a collar 10-, composed for example, of polyurethane foam, which is slightly proud of the surface of the roller 1.
  • the pin 8 In operation, with the roller 1 stationary, the pin 8 is withdrawn and a length of paper, say 15 feet, is applied to the device by inserting one end of the paper into the clips 9 and rotating the sleeves 4 until the paper P is in the form of a loosely wound roll. The pin 8 is then inserted and the shaft 2 driven until the surface of the roller 1 attains a speed approximately equal to the speed at which the paper is to be dispensed. Since the roll of paper is not tightly wound upon the roller 1 it will not at this stage be affected by rotation of the roller 1.
  • the loose roll of paper is tightened down onto the roller 1, thereby accelerating the paper roll to approximately the desired speed, the inner end of the paper being pulled out of the clips 9 which remain stationary.
  • the effect of the roller 1 rotating inside and with the tightened roll of paper is to tend to loosen the roll of paper thereby freeing it from the roller, so that subsequent delivery of paper takes place with the following two effects occurring rapidly and alternately.
  • the paper is delivered from the device at approximately the desired speed, thereby enabling the pinch rollers or other drive means to accelerate the paper to the desired speed in a very short period of time, and thereafter to drive the paper at the desired speed without danger of breakage or marking.
  • a device for dispensing paper or like material from a roll of such material which includes (a) a driven shaft mounted for rotation,
  • roller means provided upon said shaft for rota tion therewith, said roller means being adapted to support a loose roll of material
  • (d) means for applying a frictional drag to the inner end of the roll thereby tending to re-tighten the roll onto the roller.
  • a device as claimed in claim 1, wherein the means for applying a frictional drag includes at least one normally non-rotatable sleeve mounted inside the roll.
  • a device as claimed in claim 2, wherein the means for applying a frictional drag includes two normally nonrotatable sleeves mounted inside the roll one at each end of the roller means.
