Patent ID: 7036763

Claim:
An apparatus for winding a continuously oncoming film web ( 1 ) onto successively deliverable winding tubes, including a rotatably drivable contact roller ( 2 ) for delivering the film web ( 1 ) in a feeding direction, and as associated with the contact roller ( 2 ) the apparatus comprising: a winding station (II) for a first winding tube ( 30 ), located in the winding station (II), for winding the film web ( 1 ) into a coil ( 100 ); a winding preparation station (III) for receiving a second winding tube ( 3 ) which upon a change of winding tubes replaces the first winding tube ( 30 ) wound with the coil ( 100 ) of the film web ( 1 ) in the winding station (II); a transverse-cutting device ( 4 ) for cutting the film web ( 1 ) crosswise in a region between the winding station (II) and the winding preparation station (III); upon a change of the winding tubes, the winding tube bearing the coil removable from the winding station (II), the transverse-cutting device ( 4 ) for cutting the film web ( 1 ) crosswise transferable from a position of repose into a working position, and upon severing of the film web ( 1 ), a leading end ( 10 ) of the trailing film web ( 1 ) being formed, the formed leading end ( 10 ) of the film web ( 1 ) deliverable to the second winding tube ( 3 ) located in the winding preparation station (III) and wound onto the second winding tube ( 3 ), and the new winding tube ( 3 ) after receiving the leading end ( 10 ) of the film web ( 1 ) being transferable from the winding preparation station (III) into the winding station (II); and downstream with respect to the feeding direction of the film web ( 1 ) guided via the contact roller ( 2 ), of the winding preparation station (III) receiving the second winding tube ( 3 ), a charger ( 6 ) and a blower device ( 7 ) being disposed, and with the charger ( 6 ) the second winding tube ( 3 ) formed of an electrically nonconductive material electrostatically chargeable, and with the blower device ( 7 ) an air stream (L) acting in a second region between a surface of the contact roller ( 2 ) and a side toward the contact roller ( 2 ) of the leading end ( 10 ) of the film web ( 1 ) being generated counter to the feeding direction of the film web ( 1 ) and counter to a direction of rotation of the contact roller ( 2 ), and the end ( 10 ) of the film web ( 1 ) being lifted from the surface of the contact roller ( 2 ) and guided to the second winding tube ( 3 ).
