Abstract
A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.
Claims20
A paperboard carrier suitable for use in winding a material thereon, the carrier comprising:
- one or more strips of paperboard secured together to form an elongate structure, the elongate structure defining an outer surface;
- and
- a coating disposed on the outer surface in a predetermined region, the coating comprising a coating agent and a solvent.
A method of manufacturing a paperboard carrier suitable for use in winding materials thereon, the method comprising the steps of:
- in a first operation, winding one or more strips of paperboard about a mandrel to form an elongate structure defining an axis (A), the elongate structure having a cylindrical body, the cylindrical body having an outer surface and opposing first and second ends;
- in a second operation, cutting the elongate structure to create a carrier having a desirable axial length;
- and
- in a third operation, using a plurality spray nozzles to apply a coating onto the outer surface.
A paperboard carrier suitable for use in winding a material thereon, the carrier comprising:
- one or more strips of paperboard secured together to form a cylindrical elongate structure, the cylindrical elongate structure defining an outer surface;
- and
- an ink identifier printed onto the outer surface in a predetermined region, the ink identifier having a barrier property that minimizes the transfer of chemicals between the ink identifier and the material.
