The rewinding machine is generally used for rewinding and cutting of mica tape, paper, and film, serving the purpose of dividing materials. It is commonly used to cut wide rolls of materials, playing an important role in subsequent re-cutting. It is a specialized device for paper, mica tape, and film. The rewinding machine is used to sequentially rewind the paper rolls produced by the paper machine (referred to as raw paper rolls) into finished paper for shipment. The use of AC drive instead of DC drive in the paper machinery industry has become a development trend. The paper rolls obtained from the roll paper machine are relatively loose, and may have internal damage or broken ends, with uneven edges and widths, making them unsuitable for direct use in paper processing or printing machines. Most types of paper (such as newsprint, letterpress paper, packaging paper, etc.) must go through the rewinding machine for trimming, cutting, splicing, and rewinding on a paper core to form finished paper rolls that meet specific specifications and tightness requirements before shipment. The rewinding process mainly accomplishes three tasks: first, trimming the raw paper's rough edges; second, cutting the entire raw paper into several widths that meet user specifications; and third, controlling the diameter of the finished paper roll to meet shipping specifications.
