Definitions

• the invention relates to a method for packaging elongate goods, such as extrusion profiles, preferably immediately after the goods have run out of a production machine of the goods, with a packaging material such as film or paper webs.
• the object of the invention is the object of a generic method in such a way that short-term and cost-saving long goods are packaged. This object is achieved first and foremost by a method having the features of claim 1, wherein it is based on the fact that the packaging material is requested transversely to the longitudinal extent of the long goods, that the long material is inserted from above into a forming loop, that then opposite Ends of the loop are driven against each other, a separation on the feed side of the packaging material is made and that the loop ends are connected to each other to secure the long goods.
• a method is specified, which is particularly suitable for the packaging of elongated goods.
• profiles coming out of the extrusion machine come into consideration, which profiles can have a length of more than 3 meters. It is also possible that several extrusion profiles can be wrapped in juxtaposition.
• the method proceeds in such a way that first the packaging material is required in a web transversely to the longitudinal extent of the long material. This web forms on the conveyor an upwardly open loop, in which the long goods is inserted. Thereafter, opposite ends of the loop are driven against each other. There is then a separation on the feed side of the packaging material, so that the loop ends for securing at the long goods, possibly consisting of several extras sion profiles, are interconnected.
• the long goods receive short-term and cost-saving the wrapping packaging. It provides more protection than a helically applied packaging.
• the packaging material which preferably withdrawn from a supply roll, with an axial projection with respect to the longitudinal axis of the long goods with respect to the front and / or rear end required.
• the material used for the packaging material may be a plastic film, a fabric or a paper web. If the material is a plastic film, it is in accordance with the invention that the loop ends be joined together by welding. The welding extends over the entire width of the plastic film and thus over the length of the long goods. Possibly also a selective or partial welding over the width of the plastic film would be possible.
• the over the long goods protruding ends of the plastic-like packaging material can be welded, so that the long goods rests in a completely closed bag and accordingly receives a high protection.
• a paper web is selected as the packaging material, it is advisable to join the loop ends together by gluing.
• a double-sided adhesive strip For this one can use, for example, a double-sided adhesive strip.
• a Verp insurance material is selected, the width of the web is adapted to the length of the long goods.
• the method operates in such a way that the packaging material is supplied via a feed table and is held in the inlet direction by a holding part arranged further to the front, with a free-running section between the holding part and the feed table.
• This free-running section serves to transfer the long goods to the packaging material. This transfer comes contrary to the fact that the free-running section is supplied in such a way that already forms the loop before inserting the long goods. So a bag is formed for the long goods, which is tuned in their nature to the dimensions of the long goods.
• the feed table fulfills a double function in that, after inserting the long goods, the loop is closed by moving the feed table against the holding part.
• the feed table guides the packaging material during feeding.
• the loop is formed by him as a result of the distance to the support member, which in turn is closed by the feed table by ancestors thereof. In this way, a closed bag is formed for receiving the long goods. If the loop is closed by clamping by the feed table, one can dispense with additional closure components, which proves to be favorable in terms of process engineering. After this closing, the feed table is moved together with the mounting part in the finished position position. This Verlagerang is also exploited, at the same time nachzug packaging material in the course of the process in the finishing position.
• finishing position further process steps can be made. There may be carried out a connection of associated end portions of the loop, after previously on the supply side separation of the packaging material has been carried out.
• This finishing position is particularly suitable for making a closure of the loop at one or both ends, occluding the end faces. This sealing can be done in the appropriate manner depending on the packaging material used. Only by loosening the Klemmhalterang then the packaged long goods is released for removal. Along with this method step, the packaged long goods are stored for removal by releasing the Klemmhalterang on an associated with the feed table acceptance table. From here, the coated long goods, which can be, for example, extrusion profiles, comfortable be removed.
• the holding part can also hold the packaging material by means of a negative pressure, and, as an alternative, also, for example, by forming the holding part in the form of a nail strip or the like.
