Abstract
Official abstract text for this publication.
The invention relates to a winding device for winding a web-shaped material, preferably a plastic film, said winding device comprising: a reel for receiving the web-shaped material, a contact roller for feeding and pressing the web-shaped material against the reel, a device for rotationally driving a still empty reel, a device for feeding the still empty reel to the contact roller. The device for rotationally driving the still empty reel and the device for feeding the still empty reel to the contact roller can act simultaneously on the still empty reel.
First claim
Opening claim text (preview).
1 . Winding device for winding a web shaped material, preferably a plastic film, said winding device comprising: a reel for receiving the web-shaped material, a contact roller for feeding and pressing the web shaped material against the reel, a device for rotationally driving a still empty reel, a device for feeding the still empty reel to the contact roller, characterized in that the device for rotationally driving the still empty reel and the device for feeding the still empty reel to the contact roller can act simultaneously on the still empty reel. 2 . Winding device, as claimed in claim 1 , characterized in that the device for rotationally driving the still empty reel comprises power transmission means that act on a gearwheel, which is arranged on a reel shaft of the reel. 3 . Winding device, as claimed in claim 1 , characterized in that the device for rotationally driving the still empty reel comprises power transmission means that are at least partially elongated. 4 . Winding device, as claimed in claim 2 , characterized in that the power transmission means comprise at least one sprocket chain and/or at least one toothed belt. 5 . Winding device, as claimed in claim 1 , characterized in that the device for rotationally driving the still empty reel comprises its own drive. 6 . Winding device, as claimed in claim 1 , characterized in that the device for rotationally driving the still empty reel comprises a retaining element, which can be moved, preferably pivoted, relative to the machine frame of the winding device. 7 . Winding device, as claimed in claim 6 , characterized in that the force transmission means and/or the drive is and/or are arranged on the retaining element. 8 . Winding device, as claimed in claim 6 , characterized in that the retaining element can be moved by means of an actuator. 9 . Winding device, as claimed in claim 8 , characterized in that the actuator comprises a pneumatic or hydraulic cylinder. 10 . Winding device, as claimed in claim 1 , characterized in that a sensor is provided, with which a signal can be outputted, when the still empty reel has reached or undershot a specified distance from the contact roller. 11 . Method for changing a reel in a winding device for winding web-shaped material, preferably plastic film, wherein a reel for receiving the web-shaped material is provided, the web shaped material is fed to and pressed against the reel with a contact roller, a still empty reel is rotated and held with a device for rotationally driving, and the still empty reel is moved in the direction of the contact roller with a device for feeding the still empty reel to the contact roller, characterized in that the device for rotationally driving the still empty reel and the device for feeding the still empty reel to the contact roller act simultaneously on the still empty reel.
