ABSTRACT:
A device for spreading of a top wrapping flm in wrapping in a wrapping machine. The wrapping machine is provided with a top film device which has a top film roll as well as devices for feeding and pulling the top film. These devices are arranged to spread the top film above the product to be packaged and to cut the top film to the specified dimension. The device is provided, as well, with a press plate which presses the product to be packaged from above, for the purpose of keeping the product to be packaged in position during the wrapping. The devices for feeding and for pulling of the top film are arranged on a frame of the wrapping machine, to be simultaneously movable in opposite directions with respect to one another. When products to be packaged are being exchanged and when the wrapping is interrupted, the feed device is arranged to pull a top film out of a top film roll substantially to a middle of the wrapping station. The pulling device is arranged to fetch or grasp a leading end of the top film from a middle of the wrapping station and to pull the top film across the wrapping station underneath the press plate, and to a stand-by position. At the same time, the feed device returns to its starting position and cuts off the top film to a specified dimension. A method for the spreading of the top wrapping film is also provided herein.
