Paper rewinding is a kind of rewinding equipment that rewinds the paper rolls produced by the paper making machine in turn, and the paper is rewound by paper rewinder to make the finished paper product. Its main processes include: Unwinding——Calendering ——Cutting——Rolling.
Most paper types (such as newsprint, letterpress printing paper, wrapping paper, etc.) must be trimmed, slit, jointed, and re-rolled by paper rewinder on the paper core to form a finished paper roll with certain specifications and tightness requirements. Calendering is that the dried paper is passed through a group of calenders consisting of 2-8 rollers. The pressure between wheel surface and paper surface makes the surface smoother, tighter and more lustrous.
