ABSTRACT:
DESCRIPTION
The invention relates to a method and an apparatus for preparing reels made of wound webs of material, such as paper, tinfoil or film, by removing or opening a closed outer wrapping.
The reels referred to are mainly reels of packaging material. In packaging technology, thin packaging material, for example of paper, tinfoil, foil etc., is provided as a reel, that is to say, as a wound continuous web. The reels have to be prepared for processing within the packaging machine. This includes opening or removing an outer wrapping which holds the reel together before it is put to use. This outer wrapping is predominantly an outer wound layer of the material of the reel itself, that is to say, the end piece of the material web. This is usually joined to the following layer by bonding.
The invention is based on the object of proposing measures for the preparation or provision of reels, in particular in conjunction with packaging machines, so that the reels are ready for use when the outer wrapping has been opened or removed.
To achieve this object, the method according to the invention is characterized in that a/(an) (opening) strip is separated from the wrapping in the axial direction.
The opening strip is separated, in particular torn out, from the wrapping at any desired place transversely to the circumferential direction. The wrapping is thus interrupted. The beginning of the material web thus formed can be gripped in order to pull out the latter.
The opening strip is separated by a tear-off member which grips a strip-like region of the wrapping and, as a result of the relative movement, separates it as an opening strip. The tear-off member is preferably provided with an adhesive, bonding surface which comes to rest against the circumference of the reel and thus against the outer wrapping and, as a result of the connection and the subsequent relative movement, carries out the tear-off operation.
Another special feature of the apparatus is the formation of a magazine for accommodating a plurality of reels. According to the invention, these reels are positioned within the magazine at a distance from one another and lie with their circumferential surfaces on bearing elements located at the corresponding positions, preferably on a carriage which can be driven in the longitudinal direction of the magazine, each carriage transporting one reel within the magazine.
The arrangement of the reels at an (axial) direction from one another has the advantage that any mutual influence or impediment, in particular involving the sensitive side surfaces of the reels, is thereby avoided.
