Definitions

  • the invention relates to a method for producing a material web roll wrapped around the circumference, in which a Material web wound up to the material web roll and a packaging web around the circumference of the material web roll is placed.
  • the invention further relates to a device for making a circumference packaged web roll with a web feed path and a winding device.
  • the invention is based on a paper web described as an example of a material web. she is however also applicable to other material webs, for example for foils made of plastic or metal or for cardboard webs.
  • Paper webs are in larger Widths up to about 10 m.
  • the last layer of the material web glued to the circumference of the roll of material become.
  • the web rolls are then made the winding device ejected and a packaging device fed.
  • a packaging line in usually wrapping paper, wrapped and the end faces of the individual rolls of material are covered with end covers Mistake.
  • the packaging facility requires a relatively large amount of space, among other things because in many cases it is a large number of packaging web rolls of different widths must keep in stock to roll with web to be able to pack changing widths.
  • the invention has for its object in manufacturing to save space on a material web roll.
  • This task is carried out in a method of the aforementioned Art solved in that the packaging web with the incoming material web is connected and the material web roll is rotated further.
  • the material web is preferably used before winding cut in the longitudinal direction and connecting with the Packaging web is done before cutting.
  • This has the Advantage that the packaging web in the longitudinal direction is cut exactly to the width of the material web and thus the material web roll.
  • the packaging line closes flush with the front of the Roll of material from. On the one hand, this ensures the desirable Effect that the web of material on her total axial length on the circumference of the packaging line is covered. On the other hand, you have none Problems more with an existing axial To have to handle supernatant. After all, you can achieve with this relatively simple measure that you no longer have many different widths of packaging webs must keep in stock.
  • the packaging line is automatically adjusted to the width of the roll of material to be packed customized. This approach has besides the space saving is another advantage.
  • the packaging web is preferably one at its end connected to the material web again. This results in in a configuration a very stable network between the packaging web and the material web.
  • the packaging web is together with the Material web wound up.
  • the outer layers of the web roll are alternating or sandwich-like from several layers of packaging web and material web educated. This creates a very intimate connection of packaging web and material. The risk, that the roll of material in the peripheral packaging axially displaces (telescoping) becomes very kept small.
  • the material web is preferably in the region of the second Connection with the packaging web with the surface the web roll glued.
  • the second connection with the packaging web takes place at the end of the material web. So there are two bonds, namely once on the radial inside and once on the radial outside of the material web. This not only provides a stable attachment of the end of the Packaging web on the circumference safe, but also one stable fastening of the end of the material web on their material web roll.
  • the material web in the running direction behind the connections is cut with the packaging web, the end the packaging web again connected to the material web becomes.
  • the peripheral packaging practically exclusively from the packaging line without intermediate material webs.
  • the material web is tracked, for example to start wrapping a new material web is necessary, relatively simple.
  • the material web is through the packaging web pulled back to the web of material, so that again Threading operations can be omitted.
  • the packaging web is preferably in the running direction before reconnecting to the perimeter of the web roll attached. So you make sure that the beginning the "new" material web up to the immediate neighborhood the web roll can be pulled. If the packaging web on the "old” material roll is attached, you can the packaging line cut through and eject the old roll of material. When winding a new web roll then a small remainder of the packaging line Roll core. However, this is acceptable because of the leadership the material web in the winding device practical requires no additional effort.
  • the material web or packaging web is preferred weakened, especially perforated, in Direction behind an area in which they are at the Surface of the web roll are attached.
  • the Question whether the material web or the packaging web is weakened depends on whether the material web together with the packaging line to the extent of Roll of material is wound up or whether you have the material interrupts and only winds up the packaging web. In the latter case, the packaging line and in the former case the web of material is weakened, for example perforated.
  • the weakening has that Advantage that you still have a certain traction can to the material web or the packaging web to the desired position. If then but in this position a higher pulling force is applied then the material web or the packaging web breaks without additional interventions by Cutting or knocking off are required.
  • the packaging or material web is preferred when the roll of material web is ejected from the winding device tore off. For this purpose it is only necessary to hold the incoming material web. If the roll of material then out of the winding device is moved out, then you have to be relative anyway apply high forces. These are easily in the Location, a separation along the line of weakness or perforation perform.
  • the packaging web from several cross to the direction packaging lanes arranged side by side that overlap each other, taking the Overlap area so that it is outside a Edge of the web roll runs.
  • packaging lanes have mother roles, the ones of which have not yet been cut Material webs are pulled off, a relative large width of up to 10 m.
  • Packaging lanes However, wrapping paper is usually only available up to widths of about 4 m. If you have all the web rolls, which are cut from a parent roll, wants to pack at the same time and in the same way these lead to problems. However, these problems will avoided by having the desired width of the Packaging web generated by the packaging web composed of several sections that overlap each other.
  • edge protection strips outside the thickened Diameter are applied, then you can Outside diameter must be made at least as large as the thickened diameter, so that the material web rolls packed in this way can roll straight ahead again.
  • the thickened Diameter no significant influence.
  • the object is achieved in a device of the type mentioned kind solved in that a packaging web dispenser one opening into the material web feed path Has output path.
  • the Packaging web of the material web roll to the same Kind is fed as the material web itself. Accordingly become complicated threading or Avoid guidance devices with which the packaging line the scope of the web of material are fed have to.
  • the packaging web can with this configuration rather be drawn from the material web (and vice versa if necessary).
  • the winding device is used twice and once for winding the material web to the material web roll and the other to generate the rotational movement that is necessary to the packaging web on the circumference of the material web roll wind up.
  • a longitudinal cutting device is preferably in the material web feed path arranged and the output path opens in front of the slitter.
  • the Packaging web automatically cut to the same width, like the web of material.
  • the packaging line then has exactly the same axial extent as that Roll of material web.
  • the roll of material web is therefore open their entire axial length from the packaging web covered without a supernatant. The alignment the packaging web to the material web roll automatically.
  • a first adhesive switching station is in the Area of the mouth of the output path arranged.
  • the Bonding station creates an adhesive layer or Area between the packaging web and the material web, preferably on the packaging line. But it is also possible to apply the adhesive layer on the material web produce.
  • the adhesive layer can be on many different Sages are generated.
  • the glue in the glue placement station is "activated".
  • Such adhesives can, for example be formed by a rubber coating by the Water supply is made sticky. It can but also a hot glue, which is then sticky when it is heated.
  • a second adhesive transfer station arranged in an area in front of a nip is the roll of material web with a roller forms. While the first adhesive switching station to do so serves the packaging web and the material web with each other to connect, the second adhesive switching station is used to bring about "end sheet gluing", i.e. the end of the packaging line or the end of the the material web connected to the packaging web Determine the scope of the role. If the radial inside the material web or the packaging web sticky has been made, then it is sufficient if this end the nip between the material web roll and the roller (e.g. a support roller) passes through with sufficient Strength to be pressed against the web roll.
  • the roller e.g. a support roller
  • a weakening device is preferred, in particular Perforator, in the neighborhood of second adhesive switching station arranged.
  • the weakening device then either weakens the web or the packaging line near the through the second adhesive application station applied adhesive. You can still use the packaging line or retighten the material web. A seperation is possible by simply tearing it off.
  • the perforating device perforates the web of material if previously Material web and packaging web wound up together have been behind the one above the other Bonding of packaging web and material web and material web and web roll. It perforates the Packing web when the packaging web is wound up alone between the gluing the packaging web with the material web and the adhesive the packaging web with the material web roll.
  • the winding device has a changing bed and a Material web holding device in the entry area of the changing bed is arranged.
  • the web holding device holds the web to two functions fulfill. For one, it makes it easier to tear off the Material web or packaging web when ejecting the Roll of material from the winding device. On the other hand it holds the "beginning" of the web so that with the insertion of a new winding core, a new one Winding process can begin.
  • the packaging web dispenser preferably has several slidable transversely to the direction of travel of the material web Packaging web rolls for dispensing overlapping one another Packaging lanes. As related to above described the process, it is possible in this way even then several material web rolls at the same time to pack when the width of the parent roll, from the the web rolls are cut, the width of a single packaging line. The packaging line is then simply by several in the axial direction adjacent packaging lanes formed, that overlap each other.
  • the packaging web dispenser has a longitudinal adhesive device. In some cases, it is enough that the packaging webs just overlap and with a certain Wind up tension. Even better packaging but one achieves that the neighboring Packing lanes in their overlap area with each other be glued.
  • a control device provided an adjacent area of overlap Packaging webs outside of longitudinal edges the web rolls stops. Because of the overlap area a packaging web section with double Thickness is formed in this way Make sure that the resulting increase in diameter the packaged web roll is not in an annoying Area. So it is from the edges of the web roll kept away.
  • the task is the beginning of a web of material mentioned type in that the width of the Packaging web exactly the width of the material web roll corresponds and the packaging line in at least one Section in the circumferential direction radially below the material web lies.
  • Such a web roll saves on its manufacture Construction space because it is not necessary a Variety of packaging webs of different widths to keep in stock. It is also for their manufacture possible packaging as a subsection of the winding to watch. With this configuration, however, it is with a section at the beginning or at the end of the Wrapping or packaging practically unavoidable, that the packaging web and the material web in the radial direction lie on top of each other so that the packaging line is inside.
