<p>In the application of preprinted film wrappings around packing containers it is sometimes required that the text or decorative pattern of the wrapping should be located in a certain position in relation to the edges of the finished packing container. One method of application of a film wrapping around an object, e.g. a packing container, makes this possible in that a film web (19) is joined to a waste material web (24) and is advanced with the help of this until the decoration is situated in a predetermined position. Subsequently the packing containers (1) are wrapped whilst the film web (19) is delivered from a film roll (2) whereupon the sealing is performed on a previously unused part of the film web. An arrangement for the realization of the method comprises co-operating sealing jaws (15,16) and a conveyor (5) consisting of two parallel parts.</p> |
