Method and apparatus for plate winding of long sheet

A method of winding a long sheet around a plate, comprising the steps of:

• rotating a plate bobbin on a rotary axis thereof and winding a long sheet on the plate bobbin;
• and
• moving a rotary axis of a nip roll along a repeating movement locus one cycle for each 180 degrees of rotation of the plate bobbin so that the nip roll, disposed approximately parallel to the rotary axis of the plate bobbin, moves continuously in one direction along the surface of the plate bobbin so as to be rotated from above the long sheet such that, while the long sheet is being wound on the plate bobbin, the long sheet is depressed against the plate bobbin by the nip roll, and wherein the maximum length between two end points of the repeating movement locus in approximately one half or less the length of the plate bobbin in the direction in which the long sheet is wound on the plate bobbin.
