Definitions

  • the invention relates to a paint roller wrapping device and in particular to a paint roller wrapping device for thermally bonding a fabric about a paint roller core tube.
  • Conventional paint rollers are constructed from a strip of fabric helically wound around and adhered to a long rigid core tube, which is typically greater than 1.5 meters in length. Cutting the paint rollers core tube to length, and other required finishing operations are subsequently performed at a later stage within the manufacturing process as separate operations.
  • a fabric is conventionally adhered to the rigid core tube via the application of a two-part epoxy adhesive to the backing of the fabric / cover material
  • a two-part epoxy adhesive to the backing of the fabric / cover material
  • the disadvantages of using this type of adhesive is that it is hard to work with and is also an extra cost during the manufacturing process of the paint roller.
  • two part epoxy adhestves are becoming an unpopular choice because of their environmental impacts and the perceived advantages of Polypropylene tubes (which do not bond readily with traditional adhesives). !t is an objective of the claimed invention to overcome these disadvantages. Summary of the invention
  • the invention provides a paint roller wrapping device comprising a rotatable holding means for a paint roiier core tube and a first heating block arranged on said device to provide a first surface that is directly contactable with the surface of a rotating paint roller core tube, which in use, Is held by said holding means and heats the surface of a pai t roller core to a molten state that is suitable for adhering a wrapped fabric
  • This configuration is advantageous because it melts the surface of paint roller tube via direct heat conduction from a heat source; therefore providing a more accurate and controllable heat flow, with minimal unproductive heat loss and the ability to
  • the molten surface of the paint roller facilitates the attachment of a fabric via thermovision.
  • said first surface of said first heating block further comprises part cylindrical recess which is adapted to conform and cooperate with the surface circumference of a paint roller core tube.
  • This configuration is advantageous because it enables the contact heat to be uniformly applied over a surface area of the paint roiier core tube.
  • said first heating block is formed from copper.
  • said first heating Mock further comprises an electrical heating means.
  • said first heating block comprises a gas heating means.
  • a paint roller wrapping device further comprising a heating block withdrawal means for removing the direct contact of said first heating block to the surface of a paint roller tube core.
  • This configuration provides a means gaining access to a paint roller tube core that has been loaded onto the paint roller wrapping device without having to first dismantle the heating block or any associated mounting mean. This is particularly desirable if quick access if a failure occurs with the paint roller tube core, the heating block itself or both.
  • a paint roller wrapping device further comprising a second heating Mock arranged on said device to provide a second surface that is directly correctable with the surface of a rotating paint roller tube core, which in use, is held by said holding means and heats the surface of a paint roller core to a molten state that is suitable for adhering a wrapped fabric
  • This configuration provides a more uniform heating about the circumference of a loaded paint roller tube core.
  • said first surface of said first heating block is arranged opposite said second surface of said second heating block.
  • the invention provides a paint roller wrapping system comprising:
  • a heating block arranged to provide a surface that is directly contactable with the surface of a rotating paint roller core, which in use, is held by said holding means and heats the surface of a paint roller core to a molten state that is suitable for adhering a wrapped fabric.
  • the invention provides a heating block device adapted for use with a paint roller wrapping device comprising a surface that is directly contactable with a surface of a rotating paint roller core held by a rotatable attachment means of a paint roller wrapping device.
  • This configuration provides a heating block that incorporates any of the above features and is separate from the paint roller wrapping device.
  • Figure 1 shows a close up perspective view of a paint roller core tube loaded and rotating on a paint roller wrapping device.
  • Figure 1 shows a perspective view of a heating block 1 arranged in position, on a paint rotter core tube 2 that is loaded into the paint roller wrapping device (not shown).
  • An array of four electrical cartridge heaters 3 are arranged within co-operating apertures 4 of the end face 5 of the heating block 1. Each cartridge heater 3 further incorporates two attached electrical leads 6.
  • a helical arrow 7 indicates a clockwise rotating movement of the paint roller core tube 2 located within the heating block 1 and rotatably supported by the paint roller wrapping device (not shown). .
  • the rectangular heating block 1 is arranged so that it is in direct contact with the surface of the paint roller core tube 2 and whereby rectangular faces 8 and 9 interface with identical cooperating faces of a second heating block 10 to provide a seamless heat transfer about the paint roller core tube 2.
  • the circular arrangement of the four heater cartridges 3 about the paint roller core tube also contribute to the efficient heating of the heat conductive material
  • An optional second heating block 10 is also in direct contact with outer surface of the paint roller core tube 2 and incorporates an elongated concave surface 11 that is sized to enable it to be located about the paint roller core tube 2 in a position that is oppose to elongated recess surface 12 of the heating block 1.
  • the inner surface 11 of the second heating block 10 is in direct contact with the paint core roller core tube 2.
  • a fabric material 20 is applied and wrapped about the paint roller core tube 2
  • the fabric is typically a pile backed fibrous material tn use, paint roller core tubes are continuously loaded In an end to end abutting configuration and fed through a paint roller wrapping device; whereby the paint roller core tubes are held by a rotating support device,
  • a heating block which Incorporates and employs an array of electrical cartridge heaters as a heating means, is arranged in direct contact with the outer surface of the loaded core tube.
  • the core tube is typically formed from a polypropylene plastics material and is rotated as it is passed through the paint roller wrapping device.
  • the forward motion of the core tube is a forward moving helical motion whereby its outer surface is directly heated by the heating block.
  • the heating block heats the outer surface about the tube circumference until it is a molten state.
  • the temperature of the outer surface of the core tube can be controlled and regulated by a temperature controller, and/or by controlling the speed of rotation of the core tube and therefore the time duration in which a portion of the core tube's outer surface is in direct contact with the heating block.
  • a portion of fabric i.e. typically in a form of an elongated strip is subsequently applied to the molten surface of the tube after its heating.
  • the fabric is adhered to the tube, via the molten surface of the tube, by the employment of a thermovision process.
  • the thermofusion bonding of the fabrics to the tube is maintained throughout the continuous application of the paint roller tube cores to the paint roller wrapping device. Therefore in a non- limiting example of the operation of this process the surface of the tube becomes a liquid which flows into the fibres of the fabric being attached to the tube and upon setting, the molten surface is thereby bonded to the tube.
  • a continuous supply of paint roller core tube are loaded into the paint roller wrapping device, whereby each paint roller core tube is arranged end to end with a neighbouring paint roller core tube.
  • This continuous end to end configuration of loading paint roller core tubes into the paint roller device does not require the known method of loading individual paint roller core tubes onto, and the subsequent removal from a supporting mandrel Therefore the continuous operation is both faster and more efficient than any of the known paint roller wrapping solutions.
  • a second heating block is arranged on the paint roller wrapping device, wherein its contact surface with a loaded paint roller core tube is opposed the contact surface of an existing first heating block.
  • the second heating block heats opposed portions of the outer surface of the paint roller tube, therefore providing a more uniform distribution of the heat which heats the material quicker and therefore expedites the wrapping process.
  • heating blocks may be required due to the thickness of the paint roller core tube's walls and/or the plastics / material from which it is constructed.
  • the heating blocks may be heated by other heating means such as a gas or other naked flame means where manufacturing production conditions allow it in another alternative embodiment of the invention, the molten surface of the paint roller core tube adheres a plastics foam material such as polyuretnane, which is either wrapped or sleeved about the paint roller core tube.
  • a plastics foam material such as polyuretnane
  • the Invention provides a method of retro fitting heating block device to an existing paint roller wrapping device/apparatus.
