ABSTRACT:
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. A method of film wrapping around an object, e.g. a packing container, is described in which a film web is joined to a waste material web and is advanced with the help of this until the decoration is situated in a predetermined position. Subsequently the packing containers are wrapped while the film web is delivered from a film roll whereupon the sealing is performed on a previously unused part of the film web. Apparatus for carrying out the method is described which comprises co-operating sealing jaws and a conveyor consisting of two parallel parts.
