Abstract
A continuous process for imparting a striking glittering or sparkling appearance to a roll of initially non-glittering cube corner sheeting includes exposing the sheeting to a combination of heat and pressure. The process includes passing the sheeting through an extended heated zone and applying pressure to the sheeting after it has been heated. At least one belt is employed to support or carry the sheeting as the sheeting is passed through the heated zone and as the pressure is applied. In one embodiment the sheeting is sandwiched between a pair of endless belts that pass through the extended heated zone, the nip, and a cooling zone downweb of the nip. The process is particularly advantageous for converting rolls of non-glittering cube corner sheeting into rolls of glittering cube corner sheeting.
