Abstract:
1. A method for the use of a packaging apparatus, wherein the packaging apparatus is provided with folding means for bringing the longitudinal edges of a continuous moving film web towards each other, the two longitudinal edges, brought towards each other, overlapping for forming a continuous package tube, while downstream of the folding means a cross sealing device is provided with the aid of which, transversely to the transport direction, cross seals are provided in the package tube, while upstream of the folding means with the aid of two pairs of drawing rollers, the film is stretched such that after application of the cross seals, the film still shrinks in a longitudinal direction in order that packages are obtained in which the cross seals substantially abut against products packaged therein, so that the package extends relatively tight-fittingly around the products, said method comprising the steps of: unwinding the film web from a film web roll which is placed on a roll holder of the packaging apparatus: guiding the film web in a horizontal plane over a conveyor belt whose transport speed in use, substantially corresponds to the speed of movement of the film in the horizontal plane, while the film web is downstream of the two pairs of drawing rollers; arranging a pulling device above said conveyor belt, directly, or at a limited distance upstream from the cross sealing device; engaging the package tube with the pulling device at the location of the overlapping edges; and holding the film in a stretched condition with the aid of the pulling device, while the film is between the downstream pair of drawing rollers and the pulling device.
