<p>A method of winding a continuously moving web (10), such as a flexible polymer film, by forming leading web edges (102) and contacting them in sequence with a number of cores (12) for adhesion thereon so as to start winding consecutive web portions onto the cores; when a web portion of a predetermined length has been wound onto a given core, the web is cut to form both the trailing edge (101) of the wound web portion as well as the leading edge (102) of the next web portion; instead of using a conventional sticky material, such as an adhesive tape, for securing each leading edge (102) of the web (10) on the corresponding core (12) for initiating winding thereof, an electrostatic potential difference is provided between the core (12) and the leading edge (102) so that the latter will be caused to electrostatically adhere to the core surface. An apparatus for use in this method comprises a cutting device (26, 26 36) for separating the moving web (10, 20, 30), a support (13, 23, 35) for rotatably holding a subsequent core (12, 22, 32) close to the web when the next leading edge is formed, and a generator (17, 27 374) for producing an electrostatic potential difference between each leading edge and the corresponding core.</p> |
