Definitions

  • the invention relates to a method for producing a packaging and / or transport unit, consisting of a stack with a plurality of at least two insulating panels of at least limited elastic material, in particular bound with binders mineral fibers, preferably rock wool and / or glass wool, wherein the insulation panels of an endless nonwoven fabric separated, arranged with their large surfaces adjacent to each other in the stack and then with at least one stack at least partially surrounding, shrinking under heat envelope, preferably provided in the form of a film and / or at least one band and an apparatus for performing the method ,
  • Natural fibers such as wool, flax, coconut, hemp, synthetic fibers, such as polyester fibers or man-made glass fibers are suitable for the production of sheet-like or plate-like insulating materials for thermal and / or acoustic insulation.
  • Mineral wool insulation materials represent the most significant group of fiber insulation materials in terms of quantity.
  • the mineral wool insulating materials are differentiated into glass wool and rock wool insulating materials.
  • Glass wool insulating materials are made from silicate melts with high levels of alkali and boron oxides. These melts can be withdrawn through nozzles to mineral fibers, these nozzles being arranged in walls of bowl-shaped and rotationally driven fiberizing devices.
  • the mineral fibers are usually impregnated with an organic binder, primarily a mixture of phenol-urea-formaldehyde resins.
  • the mineral fibers produced in this method of manufacture are relatively long and smooth and are collected underneath the fiberizing device on a collecting and conveying belt. The mineral fibers are piled up at a desired height and transported continuously with the conveyor belt as a mineral fiber mass.
  • This type of lamination of a continuous mineral fiber fleece formed from the mineral fiber mass is generally referred to as direct collection. Since the efficiency of the shredders used with several hundred kilograms of mineral fibers per hour is not so high, several shredders are usually placed one after the other on a production line, that is a collection and conveyor belt.
  • the bulk density of the mineral fiber fleece is adjusted as a function of the conveying speed of the endless mass flow of fibers.
  • This mineral fiber fleece is then fed to a hardening furnace in which the thermosetting binders mentioned by way of example are cured and the mineral fiber fleece is fixed.
  • hot air is sucked through the permeable mineral fiber fleece, so that the intensive energy transfer leads to rapid curing of the binder.
  • the insulating felts and insulation panels made of glass wool have in common an extremely layered structure parallel to their large surfaces. This structure leads to a low thermal conductivity and a high ductility perpendicular to the large surfaces. In contrast, the connection between the individual mineral fibers is perpendicular to their longitudinal axis, so the transverse tensile strength of the structure very low. Parallel to the large surfaces, the stiffness of the insulating felts and insulating panels is much higher, regardless of the direction of loading.
  • Insulation felts made from glass wool can be rolled up easily and with a high degree of compression of up to approx. 60% without tearing and largely regain the original thickness.
  • This type of treatment is counteracted by the fact that the thickness tolerances for the type of application WL in accordance with DIN 18165 Part 1 allow significantly greater thicknesses than are the case for application type W insulation panels.
  • the Dämmfilze can therefore be prepared with a relatively large excess thickness to compensate for strength losses and then compressed.
  • Glass wool insulation boards must not be compressed as much as possible in order not to fall out of a permissible thickness tolerance field. Since the degrees of compression are not tuned steplessly, but in connection with usual packaging units or bulk, packaging or transport units and in relation to the volumes, in particular the height of the means of transport (truck, railway wagon), compression rates of about 20% already contribute the packaging units at significant cost savings.
  • Rock wool insulation materials are produced from silicate melts that are rich in alkaline earths, iron oxides and, as network formers, contain not inconsiderable amounts of aluminum oxide.
  • Rock wool insulation materials were originally produced only from diabase and chemically related basalts with small amounts of lime or dolomite.
  • the raw material blends contain high proportions of suitable residues from the production of other materials and accumulating waste materials from the production or recycling of mineral fiber insulation materials.
  • the previously produced metallurgical wool consisted mostly of blast-furnace slags and small additions of quartz-containing rocks. Blast furnace slags are also processed today in the production of rockwool insulation materials. The independent species of cottage wool is no longer available in this country.
  • the melt for the production of rock wool insulating materials has a very steep dependence of the viscosity on the temperature, so that only a narrow temperature interval for mineral fiber formation is available.
  • the melt is processed in the majority of factories on so-called cascade shredding machines. These machines usually have four staggered rollers rotating about horizontal axes. The melt is passed in a thin layer successively over the rollers. Depending on the speed of rotation, the presence of germs and temperature, liquid bodies, which assume either spherical or fibrous form, as well as other intermediate forms, first dissolve out of the melt. In this way, about 50% by mass of useful mineral fibers can be recovered from the melt.
  • the other half of the melt goes into spherical to stem-like particles, which are separated by air classification of the mineral fiber mass. Nevertheless, about 25 to 30% by weight of spherical particles remain in the mineral fiber mass.
  • the fiberizing machines with up to about 5 tons throughput per hour, are considerably more efficient than the fiberizing devices used for the production of glass wool.
  • the mineral fibers of rockwool are bound with binders, which are dissolved or colloidally distributed in water as in the production of glass wool.
  • binders which are dissolved or colloidally distributed in water as in the production of glass wool.
  • the individual mineral fibers of rock wool are much shorter than the mineral fibers of glass wool.
  • the rock wool mineral fibers are curved in themselves and get caught in the air stream easily with each other, forming more or less large flakes.
  • the rock wool mineral fibers can be picked up directly.
  • a production plant with high performance it is not possible to achieve a completely homogeneous distribution of the mineral fibers over the length, width and height of a mineral fiber fleece to be produced.
  • an endless mineral fiber mass flow must either be cooled by large amounts of water or the polycondensation reaction of the resin mixtures used continues to run, resulting in premature curing of the binder.
  • the removal of the water is associated with a high energy demand and thus uneconomical. All of these negative aspects have led to the fact that the mineral fibers impregnated with binders are deposited on a conveyor belt in a thin primary web and transported away.
  • This primary web is now placed meandering transversely to the conveying direction of a further conveyor belt on this second conveyor belt by means of a pendulum device.
  • a pendulum device for example 2 or 4 m and its basis weight, for example about 300 to about 800 g / m 2 , are in the primary nonwoven formed secondary mineral fiber layer about 4 to about 12 layers obliquely and respectively offset by the pendulum stroke.
  • the primary nonwoven layers in the secondary mineral fiber fleece are on the one hand in the horizontal direction quite easily, and on the other, and this particular compressed in the vertical direction.
  • the secondary mineral fiber fleece is compressed more strongly in the longitudinal as well as in the vertical direction. there The individual mineral fibers are brought in a steep position to the large surfaces of the secondary mineral fiber fleece and at the same time significantly increases the bulk density of the mineral fiber mass.
  • the curing of the binder takes place in the rock wool insulating materials in analogy to the glass wool insulating materials by means of hot air in a curing oven.
  • the lower limit of the gross density of rock wool insulation boards is currently about 24 kg / m 3 , which corresponds to about 15 - 17 kg mineral fibers / m 3 .
  • the upper limit of the insulation boards produced in the manner described is approximately at about 55 kg / m 3 (38.5 kg mineral fibers / m 3 ).
  • the mineral fiber equivalents are given here as essential elements of presentation, because the unbound non-fibrous constituents only marginally or not at all affect the mechanical properties relevant here in the first place.
  • the endless sheet-like mineral fiber fleece is usually split longitudinally in the longitudinal direction and separated the insulation panels in the desired width of the partial webs.
  • a different approach can be chosen.
  • Glass wool insulating materials can also be produced in single layers with small thicknesses.
  • the endless mineral fiber fleece is already separated on the production line horizontally in two to four layers
  • a separated from the mineral fiber fleece insulation board therefore has in their longitudinal direction a significantly higher stiffness and bending tensile strength than transversely to its longitudinal direction.
  • the rock wool insulation boards can therefore be compressed only with significantly higher power input and develop due to the higher spring constant of the mineral fiber mass also a correspondingly high counter or restoring force. Excessive deformation also risks causing the mineral fibers to break, relocate or destroy the bonds between the mineral fibers. In this case, irreversible structural changes can occur. Since the deforming forces attack primarily at right angles to the large surfaces, either the desired nominal thickness is no longer achieved or when releasing large voltages this nominal thickness is exceeded in an inadmissible manner.
  • the separated insulation boards are, if necessary freed from adhering sawdust and arranged in a stack one above the other or after a rotation next to each other or stacked.
  • the height of the stack is limited by the weight of the insulating panels and by the still manageable size of a packaging unit formed from the stack. Therefore, stack heights of about 20 cm to about 60 cm are usual, but preferably the height is limited to less than about 50 cm.
  • the stack of insulating panels is wrapped with films and / or banding, which hold the stack together and against environmental influences, such as moisture protect. Furthermore, the films and / or bands are used to handle the packaging unit.
  • foils those made of polyolefins, such as polyethylene and copolymers with, for example, ethylene and vinyl acetate or polypropylene because of their material properties, especially their good shrinkage properties, the comparatively high shrinkage forces at room temperature and other advantages in the application and not least because of their low price have proven particularly.
  • Polyethylene is formed by the polymerization of ethylene.
  • high-pressure polymerization branched polyethylenes of low to medium density are primarily formed (low-density poly-ethylene, abbreviation LDPE).
  • Very low densities are found in the LLDPE types polyethylenes.
  • the so-called low-pressure polymerization results predominantly in linear high-density polyethylenes (high-density poly-ethylene, abbreviation HDPE).
  • the copolymerization with other unsaturated components allows the development of plastics with special properties.
  • EP 1 050 466 A1 distinguishes between polyethylene film (PE film) and polyolefin film (PO film).
  • the PE films are used in this prior art in thicknesses of about 25 to about 250 microns, the PO films with thicknesses of about 8 microns to 35 microns, but especially from 15 microns to about 19 microns.
  • Shrink films are usually made by the blow and the chill-roll process of granules.
  • the granules contain, inter alia, lubricant concentrates, colorants, antioxidants and UV absorbers.
  • the films are stretched in a second operation, usually even biaxially, to reduce the thickness to the desired level and by the orientation of the molecular chains by external force an increase in the strength in this To reach direction. While maintaining the tensile forces, the O-orientation state is fixed by cooling. Relatively high elastic components, which lead to residual stresses, are to be retained. These internal restoring forces lead at higher temperatures to the desired here fast recovery, ie shrinking. With the biaxial stretching, the strength values in the longitudinal and in the transverse direction can be adjusted in a targeted manner.
  • the shrinkage force is that force which is exerted on a specimen by it during and after exposure to heat, when it is clamped at two ends so that it can not be shortened.
  • the maximum heat shrinkage which is determined at a certain temperature and after cooling to room temperature.
  • specific shrinkage forces which are time-dependent.
  • stress relaxation Another important property of shrinkable films is stress relaxation, which indicates the temporal decay of stress in a deformed material, if this deformation is kept constant.
  • the stack of insulation boards is fed on a conveyor belt a banding and provided with a sheath.
  • banding for other objects are in the already mentioned EP 1 050 466 A1 and EP 718 198 A1.
  • banding shrink film rolls are located above and below a conveyor plane. Plastic film sheets drawn from the shrink-film rolls are brought together and joined together by a weld. They thereby form a foil curtain.
  • Corresponding banding stations are also in the production of packaging units from each stack of insulation boards in use.
  • the stack of insulation boards is conveyed against this film curtain, wherein the film webs are tracked. Then the promotion is stopped.
  • a beam arranged above the conveying plane of a welding press is moved against a lower beam arranged, for example, in the conveying plane.
  • the jaws are coated with Teflon to prevent the films from sticking.
  • thermoplastic films are heated to plastic flow and joined together under pressure.
  • the welding changes the structure of the interconnected plastic films. Only really good weld seams almost reach the breaking strength of the base materials.
  • shrink films are preferably used, which consist of LDPE or mixtures of LLDPE and LDPE.
  • the thicknesses of the plastic films are reduced to about 20 microns to about 100 microns, preferably about 35 microns to about 65 microns.
  • the heat impulse welding is preferred.
  • the heating elements are heated by power surges, which are matched to the type and thickness of the films to be joined, in no time.
  • Double beams are used, which produce two parallel welds. The two film webs are severed between the beams or the welds with the aid of an interposed filament. The upper bar is moved back to the rest position.
  • the band is significantly wider than the stack of insulation panels.
  • the overhang on each face of the stack of insulation boards may be a few inches or reach well over half the height of the stack of insulation boards. Because of the resilience of the insulation panels and the shrinkage of the band will avoid a flush or slightly over-wide band. Otherwise, there is a risk that the insulation panels at the ends of the packaging unit circumferentially slip out of the band, which would primarily lead to a visual impairment.
  • the over the faces of the stack projecting film sections hang down and lie on the conveyor belt.
  • the stack of insulating panels with the envelope made of plastic film is then fed to a shrink tunnel, as it can be found for example in EP 1 050 466 A1, US Pat. No. 6,151,871 A1 or EP 1 044 883 A1.
  • the heating of the plastic films by means of heated air, which is brought to the surfaces of the stack of insulation boards.
  • the height of the air temperature is adjusted according to the throughput through the shrink tunnel and the thickness of the plastic films.
  • a typical temperature range is, for example, between about 130 and 170 ° C.
  • the banded stack of insulation boards is for this purpose on a good air-permeable conveyor belt, which consists for example of spaced-mounted metal rods or a wire mesh. The spaced-mounted thin metal rods hinder the contraction of the films little.
  • the plastic films After the shrinking process, the plastic films have been tightly applied to the surfaces of the insulation panels of the stack and hold this stack together. Since the friction coefficient of the insulating panels is very high, thin plastic films with low shrinkage force at room temperature are sufficient to secure the insulation panels against slipping within the stack.
  • the shrinking process also changes the position of the welds previously produced between the film webs. They are now each in the lower third of the two side surfaces of the stack.
  • the air duct in the shrink tunnel is formed so that the overhanging at the end faces of the stack plastic films are bent to the center of each end face and welded together in this position.
  • the heating can be more intense here than in the region of the side surfaces of the stack, in order to achieve a partial welding or a stronger shrinkage.
  • the plastic films attach themselves to the stack of insulation boards and thus stabilize it also in the longitudinal direction.
  • the thicker and firmer film areas on the end faces due to the shrinking also allow intervention here with the hands and the handling of the packaging unit.
  • the enclosure often also has openings as a result of differential heating or obstructed shrinkage.
  • the wrapper can tear through hard insulation panels at the edges or in the region of the welds. The reason for this is from the outset imperfect welds, but also the heating of the seams twice. On closer examination, there are also significant deformations of the plastic films or discoloration of colored plastic films in a range of about 10 to about 20 mm on both sides of the welds to recognize.
  • a material thickness of the plastic film in the initial state of about 63 microns to about 64 microns is obtained after shrinking a substantially uniform thickness of about 63 microns, so that the differences in thickness are within the accuracy of a micrometer. In areas immediately adjacent to the weld seams, however, the thicknesses are only about 50 ⁇ m.
  • the invention is based on the object, a method of claim 1 for producing a packaging and / or transport unit consisting of a stack with several, at least two insulating panels of at least limited elastic material in such a way that the disadvantages of the prior art be avoided, in particular to achieve a simpler process to improve the stability of the envelope and to protect the insulation panels.
  • the solution of this task provides, in a method according to the invention, that the stack of insulating panels in the envelope is compressed before shrinking the envelope in a compressed stack.
  • the stack of insulating panels is compressed prior to application of the plastic film as a wrapper and then subjected to the enclosure in the compressed state of heating, which serves to shrink the plastic film.
  • the stack of insulating panels is first covered with the plastic film and then compressed and finally supplied to the heating in the compressed state.
  • the welds or the surface areas of the plastic film with the welds are cooled down quickly, for example, with air, CO 2 vapor (dry ice), finely sprayed water or an alternative cooling medium. This is intended to prevent these surface areas from being heated more strongly in the subsequent shrinking process and thus from shrinking more than the plastic film in the area of the further surface areas, in particular in the region of the side surfaces and / or end faces of the stack.
  • the plastic films can be shrunk to a greater extent in the area of the two end faces of the stack than in the area of the large surfaces of the stack of insulation boards.
  • the envelope can be closed or partially open in the region of the end faces of the stack.
  • the packaging units are supplied in succession to a compression station with integrated decompression device with the intervals resulting from the cycle times of the banding station. At least this area of a device according to the invention is arranged to avoid environmental influences on the result of the shrinkage of the plastic film in a housing.
  • the packaging units Prior to the entry of the packaging units in the compression station, the packaging units are rotated by 90 degrees and positioned so that the packaging units run into the compression station with one of their front faces.
  • This approach reduces the risk of the insulation panels tearing in one of their large surfaces with a steep increase in compression.
  • the compression station consists of a lower and an upper conveyor belt, which are spaced from each other in the housing. The distance between the conveyor belts is adjustable.
  • the pressure-exerting conveyors with inclinations between about 1.5% and well compressible insulation boards are also up 4% arranged converging.
  • the upper conveyor belt is arranged inclined from its horizontal orientation to the opposite conveyor belt.
  • the inclination angle is made larger, so that there is a tendency between about 4 and 8%.
  • the conveyor belt can be adjusted to each other in terms of their inclination to adjust different compression in different insulation panels can.
  • the conveyor belts consist of inherently pressure-resistant elements, for example plastic sheets stiffened with metal rods or of trough-shaped metal members.
  • the conveyor belts are coated with, for example, polytetrafluoroethylene, silicone or the like in order to prevent sticking of the plastic films to the conveyor belts.
  • the insulation boards in the packaging unit are significantly more compressed than the desired degree of compression in the finished packaging unit.
  • This increase in compression can be up to about 50% and is limited only by the fact that irreversible damage to the structure of the insulating panels are to be avoided. This compression can effectively complement a previous elastification of the individual insulation panels.
  • these portions are heated to continue the shrinking operation.
  • the heating of the plastic films is done in such a way that the furthest bulge areas are heated the most.
  • the heating of the plastic films takes place, for example, with electrically heated coils or quartz rods with different heating powers over the length of the compression station.
  • the radiators equipped with reflectors can be rigidly arranged or pivoted up and down in regular movements.
  • the distribution of hot air can be supported by fans.
  • the heating of the plastic film surfaces with hot air which is heated outside the housing and directed by nozzles targeted at the surfaces to be heated of the plastic film.
  • the flow velocity may vary over the length of the stack of insulation boards to be treated. Normally, the flow velocity is so low that the plastic films are not pressed on the insulating panels. With a sharper flow, the plastic films can also be set in a flapping motion to keep them free from de surfaces of the insulation boards. With the help of the nozzles, the plastic films can be blown with different levels of heated hot air.
  • dry hot steam can be used.
  • the heating can be continued until the highest compression or before completion of sufficient heating of the plastic films.
  • the compression station can be followed by a reaction zone in which the packaging unit is held with the last degree of compression, so that the shrinkage process starts evenly. This process can be controlled by a uniform temperature of the space surrounding the packaging unit.
  • the compressed packaging unit is transported to a decompression station, in which the compression of the insulation boards is gradually released.
  • Decompression can be faster than compression.
  • the side surfaces of the stack are optionally zonar or selectively cooled in sequence with hot air, room or compressed air or a water mist.
  • the packaging units produced in this way generally result in uneven shrinkage over the circumference of the packaging units. This also results in an increase in the material thickness of the over the side surfaces of the stack most shrunken plastic film to, for example, about 180 to 200 microns, while the material thickness of the plastic film on the top and bottom of the stack is about 80 to 90 microns.
  • transition region there is a risk of tearing the stretched plastic film by an abrupt increase in the material thickness of the plastic film.
  • a gradual increase in material thickness should be strived for or the abrupt increase in material thickness should be avoided.
  • the transition region should moreover be arranged at a distance from an adjacent edge of the stack of insulation boards, since a linear clamping point of the plastic film lies in the edge region and consequently the strongest strains can occur.
  • the distance between the shrinkage-related transition region of different material thicknesses of the plastic film regions from the edge of the stack should therefore be more than about 2 cm. This distance may preferably be formed by the targeted heating, possibly with a supplementary cooling of the edge zones of the transition region.
  • angle elements or diaphragms can be provided, for example, on the conveyor belts in the compression station and / or shrinking station, wherein the angle elements or diaphragms with the conveyor belts pass through the shrinking station. A complete shielding of the side surfaces is not useful to achieve even transitions.
  • the edges of the angle elements or diaphragms can be wavy.
  • the vertical edges of the packaging units may also prove to be sensitive to cracks since here clamping points form between the plastic films, which have previously shrunk to a greater extent on the end faces, and now remain unchanged zones. In principle, this cracking can be counteracted in a corresponding manner.
  • a band may also be provided, the welds of which are arranged on the upper and lower cover surfaces of the stack. This arrangement of the welds is possible if the insulation panels are previously placed upright against each other and then surrounded with the enclosure. Also in this case, the stack is previously rotated 90 degrees and either held laterally or pressed together in the longitudinal direction until the banderole is applied.
  • the band is pre-shrunk as described above in this case before the insulation boards are compressed and fed in the compressed state of the shrinking station. At the latest before the compression device further rotation of the packaged and provided with a preshrunk banderole or wrapping stack insulation boards is done by 90 degrees, so that the stack resumes its initial position.
  • the end faces of the packaging units are not shrunk.
  • shrinking the plastic film regions projecting in the area of the end faces can be prevented, for example, by pressing these plastic film regions against the heat during the pre-shrinking and / or the shrinking process by means of vertically arranged laterally arranged side strips.
  • This procedure leads to a banderole that is open at least after the pre-shrinkage, so that the plastic film in the shrinking station can be uniformly heated over the entire length of the packaging unit and consequently shrinks accordingly uniformly.
  • the tensile stresses and thus the risk of cracking in the plastic film are reduced, whereby the use of thinner plastic films is possible, which leads to a reduction in packaging costs and the cost of disposal of packaging materials on construction sites.
  • the heating of the plastic films can also be done with the aid of a preferably spirally moving laser steel.
  • a device which has a banding station in which a stack of a plurality of insulating plates arranged one above the other or side by side, in particular of mineral fibers, with at least one under heat shrinkage film.

  • a shrinking station in which the film is shrunk in a compressed stack such that the film rests, in particular, over a whole area on at least part of the outer surfaces of the stack.
  • film webs are welded together in the banding station by means of at least one welding bar to form a film curtain, against which the stack of insulating boards is conveyed.
  • a film curtain By promoting the stack of insulation boards of the film curtain is disposed at the top and bottom of the stack and finally connected to the advancing side surface opposite side surface of the stack by another welding process with the welding bar to a sheath, which is then separated from the film webs.
  • the film webs are guided by suitable, for example convex deflection rollers and / or brush rollers with symmetrical, outwardly directed spiral arrangement of the bristles, so that on the one hand the withdrawal resistance of corresponding supply rolls is reduced and on the other hand largely caused by the train Querfalten Strukturen in the film sections substantially , At the same time the tension is reduced, which is caused by the current against the film curtain stack of insulation boards.
  • a retractable stop in the conveying path can be provided, on which the insulating plates of the stack or the stack are aligned before the stack is banded.
  • the stop can be intermittently inserted or pushed out into the conveying path.
  • the Stop arranged in the region of the film curtain, so that the film curtain between stop and stack is arranged.

  • the deflection roller or brush roller can be supplemented by a second roller or a pressure plate.
  • the wrapper or banderole produced in this way fits snugly against the stack of insulating panels. It follows that a preshrunk process now to be performed can be performed with less energy and in less time. In addition, due to the close concern of the plastic film to the stack insulation boards, a thinner plastic film can be used, which can be shrunk by lower energies in the subsequent shrinkage process.
  • the welding bar cooperates with an abutment which is arranged in the plane of a lower conveyor belt in order to form the welds to be executed as far down as possible, ie in the area of the lowest insulation board of the stack. Both welds are thus in the range the lowest insulation board of the pile. Subsequent pre-shrink pulls the welds upward from this original position.
  • the positioning of the welds can of course also be such that the front weld is placed as always in the region of the conveying plane and the rear weld, but this requires that the abutment for the welding bar is transferred to an upper position in which the Weld is formed.

  • non-shrunk or slightly shrunken areas of the envelope 7 can be made with panels that cover the corresponding areas in the heating of the enclosure 7.

In principle, it is of course also possible to start the shrinking process only when the final degree of compression of the stack 4 of the insulating panels 5 is reached, so that the shrinkage is limited to the reaction zone 28.
  • a gradual heating of the surfaces of the envelope 7 can also be done with quartz glass emitters, on the back of heating wires are printed.
  • the printed heating wires are electrically heated and can, for example be arranged between two quartz glass panes.
  • Such quartz glass emitters not only have the advantage of a very accurate control, but they also effect an energy transfer in all three ways, ie by heat conduction in direct contact, by radiation and by convection.
  • the heating can be continued until the highest compression or after sufficient heating of the films previously terminated.

  • the packaging units 16 removed from the shrinking station 30 are thus deflected from their original conveying direction into a conveying direction running at right angles thereto, without their longitudinal axis orientation being changed.
  • the packaging units 16 reach the area of a warm air station 44 with two hot air nozzles 45 arranged opposite one another, which blow hot air onto the end faces of the stack 4 and the sections of the envelope 7 which have not yet been shrunk there.
