• the shifting movement takes place until the packaging unit is moved over the stop bar, taking the film with it.
• the packaging unit for example the package of mineral wool panels, then remains at a distance of about 10 to 20 cm behind the stop bar.
• the packaging unit is encased on three sides, approximately in a U-shape, by the plastic film. In this position the Welding bar against the stop bar and pulls another part of the plastic film from the adjacent film roll. In the stop position, an electric heater located in the welding bar is heated, so that a sweat running transversely to the transport direction is formed.
• the packaging unit After the welding seam has cooled very rapidly, it is separated in the middle in such a way that, on the one hand, the packaging unit remains completely wrapped in the plastic film and, on the other hand, the ends of the film parts unwound from the film rolls are welded together, so that they re-bond Curtain forms.

• the film wrapping of the packaged packaging unit then has two weld seams running over the entire width.
• a shrink film made of a polyethylene material is used as the plastic film.
• Such packaging units are generally extremely bulky. Since the plastic film is also very smooth, the packaging units are difficult to handle. However, they usually have to be stacked in large quantities by hand for warehousing, reloaded in trucks, unloaded at the dealer or on the construction site and finally transported for processing. In these operations, the bulkymaschines ⁇ have units of the respective craftsmen with wide spread arms detected, be lifted and carried on where they slide off because of the smooth plastic and often fall to the ground, so that the art ⁇ stoffolie may be damaged. In contrast, the object of the invention is to create a device with the aid of which such a covering can be produced that the packaging units can be easily handled.
• the object is achieved in that the welding bar and the stop bar, as seen in the conveying direction of the packaging unit, are so wide and the welding bar is provided with at least two heating zones running at a distance from one another that a carrying strap is formed on the circumference of the envelope .
• the invention further relates to a packaging unit made of mineral wool sheets or rolls with a covering which consists of a shrinkable plastic film and the ends of which are connected to one another by a weld seam, which is characterized in that an outwardly pointing carrying strap is flanged to the weld seam.

• Fig. 7 is a partial cross section to Fig. 6 through the carrying tab on an enlarged scale
• Fig. 8 is a partial cross section to Fig. 6 along section line VIII-VIII on an enlarged scale.
• two conveying devices 1, 2 are provided in the form of transport roller conveyors.
• other suitable conveying devices eg. B. endless conveyor belts are used.
• a film roll 3 is rotatably mounted vertically at a distance above the transport roller conveyor 1.
• Another film roll 4 is also rotatably arranged below the transport roller conveyor 1.

• the ends of the two film webs 5, 6 are connected to one another by a weld 7, which extends perpendicular to the image plane of FIG. 1 and extends over the entire width of the film webs.
• deflection rolls 8 and 9 which are arranged such that the lower film web 6 passes through a gap between the conveyor device 1 and the stop beam 13.
• a packaging unit 14 on the transport roller conveyor 1 which in this exemplary embodiment consists of a stack or a package of mineral wool plates 15, which are therefore stacked on top of one another.
• a welding bar 10 which can be moved up and down in the direction of the arrow by means of a linkage 11 shown in simplified form. The lifting height of the welding bar 10 is greater than the height of the packaging unit 14. In the operating position according to FIG. 1, the welding bar is in its uppermost position. If the packaging unit 14 or the stack of plates is now moved in the direction of arrow 16 in the operating position according to FIG.
• the film web 5, 6 is pulled off from the two film rolls 3, 4, so that in this operating position, the underside first and the front end of the packaging unit lying in the conveying direction is covered by the plastic film.
• the welding bar 10 is moved over the lifting height up to the stop bar 13, so that the operating position according to FIG. 3 results.
• the film web 5 lifts off a guide roller 17.

• the welding bar 10 and the stop bar 13, as seen in the conveying direction 16 of the packaging unit 14, are so wide and the welding bar 10 is with at least two in Heating zones 18, 19 running at a distance from one another provide that a carrying strap 23 is formed on the circumference of the envelope 26 during the welding process.
• the heating zone 18 can advantageously also be double, so that this results in two weld seams running closely next to one another, between which the separation process can be carried out.
• the film part of the covering 26 runs at an acute angle on the rear end face, for the sake of clarity, exaggeratedly drawn, so that there is initially a wedge-shaped space.
• the packaging unit After the packaging unit has been separated, it is fed to a shrink tunnel, not shown, where the plastic film is shrunk so that it lies tightly against the packaging unit over the entire circumference.
• both the welding bar 10 and the stop bar 13 are movably arranged by means of rods 11 and 22 which are shown in simplified form, in such a way that the two bars are approximately at the central height of the packaging unit 14 (FIG. 4) meet.
• the separating device has at least one additional tool for punching a handle opening into the carrying strap 23. 6, three handle openings 27, 28 and 29 are provided. To produce them, three additional tools are then arranged in such a way that a central grip opening 28 and two grip openings 27 and 29 located near the edge of the carrying strap 2 are created.
• the additional tools advantageously have a substantially oval cut edge, so that the handle openings allow comfortable handling.
• the carrying strap 23 is delimited on both sides by weld seams 24 and 25.
• a further oval weld seam 30 can be provided at the edge of the handle openings for additional reinforcement.
• the welding bar 10 has an additional oval heating zone near the edge of the respective handle opening 27, 28 or 29.
• the foil parts inside the handle openings can be completely punched out.
• it is also possible to design the cutting edge of the additional tool so that it extends only over the two curves 31 and 32 and a connecting edge 33 between the two curves, so that the punched-out film parts can be folded over the other opposite connecting edge 34 .
• the folding can also be carried out around the outer connecting edge 33 when the tool is turned over accordingly.
• a packaging unit is obtained from mineral wool sheets or alternatively also from a mineral wool roll, which is rolled up from a web, with a covering 26, which consists of a shrinkable plastic film and the ends of which are connected to one another by a weld seam and an outwardly facing support flange 23 being flanged to the weld seam.

• the carrying strap 23 has one or more grip openings 27, 28 and 29 which are surrounded by weld seams 30 for reinforcement. It is generally sufficient to provide only a single central handle opening. However, if the packaging units are particularly large and heavy, the two outer handle openings can be provided instead of or in addition to the central handle opening, so that two people can attack and cause particularly rapid stacking and loading, etc.
• the carrying strap can be formed along one of its edges, as can be seen in FIG. 3.
• the carrying tab 23 is, however, molded onto a covered surface in the middle height according to FIG. 5.
