Method and device for the multilayered coiling of flexible products, especially printed products, in a shingled formation

摘要

obtained prior to winding in an imbricated formation (S) printed products (16), the thickness (d) of a winding core (1) and a winding (7) tapering which imbricated formation (S,) controlled to a given value. This is done by pulling or pushing the printed products (16) within the imbricated formation (S, S _i). For this purpose, a conveyor (5) with a greater or smaller velocity (v) is driven in a second, upstream conveying means (12). The imbricated formation (S,) of a given thickness (d) on the winding core (1) together with a tensile stressed winding tape (9) always comes to lie on the outside of the coil (7) wound up. By Balancing the thickness (d) of the wound imbricated formation (S,) to a given and during the winding constant value, it is possible, regardless of the thickness of the resulting printed products (16) with a given, always constant winding band length the winding (7) always form of the same diameter.
