Definitions
- the invention relates to an insulation product comprising a base material of cellulosic pulp wool and additionally a bonding agent bonded with an adhesive to the cellulosic pulp wool.
- the invention also relates to a method for producing an insulation product, in which the base material for the insulation product is formed from cellulosic pulp wool, and a bonding agent to which the cellulosic pulp wool is bonded with an adhesive that is also applied in the method is employed to produce the insulation.
- the known insulation product employing cellulosic pulp wool and the method for producing it are of a kind in which water is sprayed into the cellulosic pulp wool when a building element, such as a wall element, is produced.
- a significant problem is presented by the fact that the insulation will settle with time, and hence the insulation product will not show sufficient insulation performance. The insulation will settle during storage and transport, and also at the actual installation site.
- a further disadvantage is that the known approach requires a long time for drying on account of the use of water, which again necessitates large drying halls or other spaces.
- the building element with inner insulation must be removed from the production line to another location for drying for the time water dries off. Also insulation produced at a construction site requires time for drying on account of the use of water.
- Patent applications DK-B-169 184, FI-A 912537 and WO-A-93/04239 disclose cellulose-based insulation elements, but in the applicant's observation, their materials, properties and methods for their production are not sufficiently effective and practicable, since the heat and moisture transfer capacity of the bonding agent and of the adhesive are not the same as with the base material. In the prior art solutions, the insulation material will not be sufficiently uniformly distributed. In addition to cellulosic pulp wool insulation products, mineral wool and glass wool insulation products are known, which may also be attended by bacterial problems.
- an insulation product of the invention which is characterized in that the bonding agent is viscose fibre, and that also the adhesive is of a cellulose-based material.
- the insulation product and the method for producing the same in accordance with the invention are based on the idea that the structure of cellulosic pulp wool is stiffened with a bonding agent adhered to the cellulosic pulp wool with an adhesive.
- the bonding agent and the adhesive form a kind of a woven supporting structure in the insulation product, and thus the insulation product will not settle.
- all materials employed are ecological, natural materials, for example in such a way that together with a base material of cellulosic pulp wool, viscose fibre which is a cellulose-based material is employed as a bonding agent, and a cellulose-based adhesive, for instance viscose glue, is used as an adhesive. It is not necessary to employ a separate bonding agent and adhesive, but the bonding agent and adhesive may also be in combination when a viscose glue that is fiberized, i.e. forms fibres that serve as a bonding agent or supporting structure, is employed.
- the insulation product and the method for producing the same in accordance with the invention afford several advantages.
- the insulation product and the method provide a novel, natural, ecological, wood-based, i.e. in practice cellulose-based, solution wherewith a wide variety of insulations can be implemented.
- the insulation product of the invention is drip-free, and it is unnecessary to apply water thereto, except for diluting the adhesive. Thus no bacterial growth can occur in the insulation product.
- the insulation product of the invention is implemented in such a way and with such materials that besides the cellulosic pulp wool also the bonding agent and the adhesive are based on the same material, i.e.
- the invention is particularly suitable for implementing a flat insulating board and for realizing an insulation to be furnished within a building element, such as a wall element, but also for implementing an insulation to be produced at a construction site.
- the insulation material will also be uniformly distributed.
- reference 1 denotes a blower through which a distributed cellulosic pulp wool-viscose fibre insulation material 2 is fed into a funnel 3.
- the bottom of the funnel 3 is made up by a wire 4 that rotates between rolls 5.
- Slabs defining the width of the insulating boards are provided on the wire 4 in the longitudinal direction thereof.
- a distributing conveyor 7 rotating at the speed of the screen conveyor 6 is located at the lower portion of the funnel 3 to rest on rollers 8.
- Pushers 9 of the distributing conveyor 7 are abutted against the surface of the wire 4 in their lowermost position.
- Adhesive is sprayed into the insulation mass through adhesive spraying nozzles 10.
- a lower viscose gauze 11 is supplied from roller 12 onto the wire 4.
- the cellulosic pulp wool-viscose fibre insulation 2 is sucked with blowers 13 and 14 into a smooth mat on top of the viscose gauze 11 onto which it is glued.
- the negative pressures produced by the blowers 13 and 14 are equalized with suction boxes 15 and 16 provided below the wire 4.
- the arrows show the direction of flow.
- a rotary brush 17 flattens out the thickness of the insulation layer 18.
- An upper viscose gauze 19 is supplied onto the insulation layer 18 from roller 20 with a screen conveyor 21.
- Wire 22 presses the viscose gauze 19 onto of the insulation layer 18, and the fabric is glued with adhesive sprayed from the spraying nozzle 10.
- the adhesive is a cellulose-based adhesive.
- the wire 22 is located between rolls 23.
- Air is circulated with a blower 24 through the insulation layer 18, thus effecting drying.
- the arrows show the flows in supply box 25 and suction box 26.
- a condenser unit 28 wherewith water is separated from the air flow and a heater unit 29 heating the drying air are located in circulation conduit 27.
- the completed insulating board 30 is supplied to rollers 31 for packaging.
- Figure 2 shows the insulation of an element with a cellulosic pulp wool insulation and the apparatus employed for the work, which has the same operating principle as the preceding embodiment.
- Reference 32 denotes a blower through which the cellulosic pulp wool-viscose fibre insulation 33 is fed into a feed funnel 34.
- Frame 35 for the element is assembled on table 36, wherefrom the frame 35 is transferred onto a pivoted wire member 37 beneath the feed funnel 34.
- the wire is denoted by reference 38 and the suction box beneath it by reference numeral 39. A negative pressure is sucked with a blower 40 beneath the wire 38, and the insulation layer for the element will be smoothed.
- a rotary valve 42 and a low-pressure chamber 43 are provided in conduit 41, by means of which a pulsating negative pressure is generated in the suction box 39. With the pulsating negative pressure, compacting of the cellulosic pulp wool insulation can be enhanced.
- a rotary brush 44 moves reciprocally upon the frame 35 of the element and evens out the insulation layer. Extra insulation is sucked away with blower 45 along conduit 46 and is returned through blower 32 into conduit 47 for reuse. Once the insulation has been effected, the feed funnel 34 is lifted away and a lid is nailed or otherwise attached onto the frame of the element. Thereafter the frame 35 of the element is turned onto table 49 with the wire member 37 supported by pivot 48 for attachment of a bottom sheet, whereafter the insulation of the element is complete.
- the insulation method of the invention operates as follows. An insulation based on cellulosic pulp wool with which viscose fibres or equivalent are admixed is distributed onto a wire with compressed air. With a negative pressure provided beneath the wire, the insulation layer is sucked into a smooth, homogeneous and resilient layer. By adapting the negative pressure to be pulsating, the compacting can be enhanced. The thickness of the insulation is evened out with a rotary brush, and extra insulation is removed. With the apparatus shown in Figure 1, insulating board 30 is produced in a continuous process. Cellulosic pulp wool-viscose fibre insulation 2 is blown onto a viscose gauze 11 laid on top of wire 4.
- Adhesive is sprayed through nozzles 10 into the insulation layer 18, and thus the insulation material adheres to the gauze 11.
- the insulation layer is cut on distribution conveyor 7 with pushers 9.
- the insulation layer 18 is evened out with a rotary brush 17, adhesive is sprayed onto the insulation layer with nozzles 10, and an upper viscose gauze 19 is glued on top.
- the wet insulating board 30 is dried with hot, dried air blown through the board 30. Air is circulated into condenser units 28 provided in conduit 27 and through heater unit 29 with blower 24. A heat pump may also be used for the task.
- the completed insulating board 30 is removed on rollers 31 for packaging.
- insulation of a building element operates in principle as a batch process, one element at a time.
- the frame 35 of the element is assembled on table 36 and is transferred for insulation onto a wire member 37.
- Funnel 34 is lowered on top of the wire member 37.
- the negative pressure provided in the suction box 39 beneath the wire 38 will even out the insulation layer (cellulosic pulp wool and viscose) into all locations, also the corners.
- a vibration effect is produced in the insulation layer by a pulsating negative pressure, produced by rotary valve 42 provided in duct 41.
- Low-pressure chamber 43 intensifies the effect of the pressure impact.
- the pulsating negative pressure reduces the power requirement for blower 40.
- the insulation layer is evened out with a vertically adjustable, reciprocally moving rotary brush 44. Extra insulation is sucked away with blower 45. Feed funnel 34 is lifted into its uppermost position; conduits 46 and 47 are resilient for lifting. A lid is nailed on top of the insulated frame 35; adhesive can be applied to the lid, or adhesive can be sprayed on top of the insulation.
- the frame 35 is turned on table 49 with the pivotable wire member, and the same operation is repeated for the bottom.
- the insulation method of the invention can be implemented in a wide variety of applications.
- the amount of adhesive and bonding fibres may be varied.
- the location and number of the adhesive spray nozzles 10 may vary. Different conveyor and transfer solutions are naturally also possible.
- the surface materials of the insulating board may vary, or they may be entirely omitted.
- the brushes 17 and 44 may be of a type other than the rotary brushes disclosed in the present application.
- FIG. 3 shows an insulating board 430.
- the insulating board includes two wide side planes 431 and 432 and four smaller end planes 433-436.
- the insulating board 430 comprises a base material 437, 438 of cellulosic pulp wool in two layers.
- the insulation product 430 further comprises a bonding agent 439, 440, 441, bonded with an adhesive 442, 440 and 443 to the cellulosic pulp wool 437, 438.
- the reference 440 denoting the middlemost bonding agent and the middle adhesive layer has two meanings, as the bonding agent and the adhesive may be in combination for example in such a way that viscose glue or other cellulose glue that is fiberized upon drying and thus forms a bonding structure, i.e. a supporting structure, is employed as the adhesive.
- viscose mesh 439 and 441 constitutes the actual bonding agent, i.e. bonding structures that are attached to the cellulosic pulp wool, i.e. cellulosic chips 437 and 438, through adhesive 442 and 443.
- the cellulosic pulp wool is cotton wood-like, wool-like wood fibre pulp.
- the bonding agent and the adhesive are of a cellulose-based material, since in such a case all materials of the insulation are based on the same material, and hence the heat and moisture transfer capacity of the bonding agent and of the adhesive are the same as with the base material, i.e. cellulosic pulp wool, thus improving the properties of the insulation.
- Viscose fibre is employed as a bonding agent, since it is a cellulose-based material and since it has a good insulating capacity.
- the viscose fibre employed as a bonding agent in the insulation product is viscose yarn, viscose mesh 439, 441, or viscose fibre dried of viscose glue, specifically 440, employed as an adhesive.
- the uppermost bonding agent 439 and the lowermost bonding agent 441 are of viscose mesh, because this provides a good bonding structure, i.e. supporting structure, which supports the cellulosic pulp wool 437, 438 and also enables cutting of the insulation product 430. Viscose meshes 439, 441 also give a neat outer surface that withstands handling.
- the adhesive 442, 440, 443 employed in the manufacture of the insulation product is a cellulose-based adhesive, preferably viscose glue, cmc glue or equivalent.
- the adhesive 440 i.e. bonding agent 440, made of viscose glue serves two purposes.
- the upper adhesive 443 and lower adhesive 442 can be contemplated to have two purposes, that is, they form viscose fibre upon drying and hence contribute to making up the bonding structure, i.e. supporting structure, and on the other hand adhere the fibres thereof and also the fibres of the viscose meshes 439, 441 to the cellulosic pulp wool 437, 438.
- the insulation material between the side planes 431, 432 could comprise cellulosic pulp wool into which viscose glue has been sprayed or otherwise introduced, as in that case fibre and also adhesive wherewith the fibre and the cellulosic pulp wool are adhered to one another are simultaneously introduced into the insulation.
- the insulation shown in Figures 3-4 is thus a planar insulating board 430, comprising two wide side planes 431, 432 and four smaller end planes 433-436.
- the insulating board comprises at least two viscose meshes 439, 441 between the end planes in the direction of the side planes.
- Cellulosic pulp wool 437, 438 is provided in the area between said at least two viscose meshes 439, 441 in the insulation product.
- Adhesive 442 is provided between viscose mesh 439 and cellulosic pulp wool 437.
- adhesive 443 is provided between viscose mesh 441 and cellulosic pulp wool 438.
- viscose fibre is also provided between the viscose meshes 439, 441 among the cellulosic pulp wool. This can be achieved for example with layer 440. Said structure can also be produced in such a way that for instance viscose yarn is introduced into the cellulosic pulp wool 437, 438 as a continuous yarn or as shorter pieces of yarn.
- the viscose yarn or other fibre in the cellulosic pulp wool layer 437 and 438 is denoted by reference 450.
- a planar insulating board 430 is produced.
- a viscose mesh made of viscose fibres is employed as a bonding agent 439, 441.
- adhesive layers 442, 440 and 443 serve as a bonding agent for their part, if they are viscose adhesive or other, preferably cellulose-based adhesive that becomes fiberized upon drying.
- the insulating board of Figure 3 has been produced in such a way that in the method adhesive 442, preferably viscose glue or other cellulose glue, is applied to a first viscose mesh 439, i.e. bonding agent 439.
- adhesive 442 preferably viscose glue or other cellulose glue
- the next step is to form a cellulosic pulp wool layer 437, i.e. a cellulosic pulp chip layer, on top of the adhesive 442.
- viscose yarn 450 can be admixed with the cellulosic pulp layer 437 with adhesive to serve as a reinforcement, as stated in the foregoing.
- viscose fibre 450 treated with adhesive is admixed with the cellulosic pulp wool 437 and/or 438 that will be located between the viscose meshes 439, 441.
- adhesive 440 which will thus also serve as a bonding agent between the layers of cellulosic pulp wool 437, 438, is applied to the cellulosic pulp wool 437.
- the next step is the forming of a cellulosic pulp wool layer 438, i.e. cellulosic pulp chip layer, upon the adhesive 440.
- a second viscose mesh 441 is laid on top of the adhesive layer 443 as a bonding agent 441.
- the next step is cutting to size of the continuous insulation band with an actuator, into an insulating board 430 having a given length.
- Figure 4 shows a step in which the ends 433-436 of the insulation product are coated by means of an actuator 460.
- the insulation product thus comprises ends 433-436 coated with adhesive, preferably a cellulose-based adhesive, such as viscose glue, and hence the insulation will withstand handling and have better properties.
- the coating is preferably performed after the cutting, to enable coating of the ends of the insulation product 430 transverse to the production line simultaneously with the lateral ends of the insulation that have the direction of the production line.
- Figures 5-7 illustrate another embodiment of the invention.
- Figures 5-7 show a building element 100, such as a wall element 100.
- the building element comprises posts 101 of a frame structure, providing the frame of the building element.

Abstract
Description
- The invention relates to an insulation product comprising a base material of cellulosic pulp wool and additionally a bonding agent bonded with an adhesive to the cellulosic pulp wool.
- The invention also relates to a method for producing an insulation product, in which the base material for the insulation product is formed from cellulosic pulp wool, and a bonding agent to which the cellulosic pulp wool is bonded with an adhesive that is also applied in the method is employed to produce the insulation.
- The known insulation product employing cellulosic pulp wool and the method for producing it are of a kind in which water is sprayed into the cellulosic pulp wool when a building element, such as a wall element, is produced. A significant problem is presented by the fact that the insulation will settle with time, and hence the insulation product will not show sufficient insulation performance. The insulation will settle during storage and transport, and also at the actual installation site. A further disadvantage is that the known approach requires a long time for drying on account of the use of water, which again necessitates large drying halls or other spaces. The building element with inner insulation must be removed from the production line to another location for drying for the time water dries off. Also insulation produced at a construction site requires time for drying on account of the use of water. It is obvious that the known method involves difficulties in production and thereby considerable economic losses. Patent applications DK-B-169 184, FI-A 912537 and WO-A-93/04239 disclose cellulose-based insulation elements, but in the applicant's observation, their materials, properties and methods for their production are not sufficiently effective and practicable, since the heat and moisture transfer capacity of the bonding agent and of the adhesive are not the same as with the base material. In the prior art solutions, the insulation material will not be sufficiently uniformly distributed. In addition to cellulosic pulp wool insulation products, mineral wool and glass wool insulation products are known, which may also be attended by bacterial problems.
- It is an object of the present invention to provide a novel insulation product and a method for producing the same, avoiding the problems related with the prior art solutions.
- This object is achieved with an insulation product of the invention, which is characterized in that the bonding agent is viscose fibre, and that also the adhesive is of a cellulose-based material.
- Said object is achieved with a method in accordance with the invention, which is characterized in that viscose fibre is employed as a bonding agent in manufacturing the insulation product, and that a cellulose-based adhesive material is employed as an adhesive.
- The insulation product and the method for producing the same in accordance with the invention are based on the idea that the structure of cellulosic pulp wool is stiffened with a bonding agent adhered to the cellulosic pulp wool with an adhesive. Thus the bonding agent and the adhesive form a kind of a woven supporting structure in the insulation product, and thus the insulation product will not settle. A further basic idea is that all materials employed are ecological, natural materials, for example in such a way that together with a base material of cellulosic pulp wool, viscose fibre which is a cellulose-based material is employed as a bonding agent, and a cellulose-based adhesive, for instance viscose glue, is used as an adhesive. It is not necessary to employ a separate bonding agent and adhesive, but the bonding agent and adhesive may also be in combination when a viscose glue that is fiberized, i.e. forms fibres that serve as a bonding agent or supporting structure, is employed.
- The insulation product and the method for producing the same in accordance with the invention afford several advantages. The insulation product and the method provide a novel, natural, ecological, wood-based, i.e. in practice cellulose-based, solution wherewith a wide variety of insulations can be implemented. On account of the bonding, i.e. supporting, structure formed therein, the insulation product of the invention is drip-free, and it is unnecessary to apply water thereto, except for diluting the adhesive. Thus no bacterial growth can occur in the insulation product. The insulation product of the invention is implemented in such a way and with such materials that besides the cellulosic pulp wool also the bonding agent and the adhesive are based on the same material, i.e. cellulose, since in that case the bonding agent and the adhesive have the same heat and moisture transfer capacity as the base material, which will improve the properties of the insulation product. The invention is particularly suitable for implementing a flat insulating board and for realizing an insulation to be furnished within a building element, such as a wall element, but also for implementing an insulation to be produced at a construction site. The insulation material will also be uniformly distributed.
- In the following the invention will be explained in greater detail with reference to the accompanying drawings, in which

- In Figure 1,
reference 1 denotes a blower through which a distributed cellulosic pulp wool-viscose fibre insulation material 2 is fed into afunnel 3. The bottom of thefunnel 3 is made up by awire 4 that rotates betweenrolls 5. Slabs defining the width of the insulating boards are provided on thewire 4 in the longitudinal direction thereof. A distributingconveyor 7 rotating at the speed of the screen conveyor 6 is located at the lower portion of thefunnel 3 to rest on rollers 8. Pushers 9 of the distributingconveyor 7 are abutted against the surface of thewire 4 in their lowermost position. Adhesive is sprayed into the insulation mass through adhesive sprayingnozzles 10. Alower viscose gauze 11 is supplied fromroller 12 onto thewire 4. The cellulosic pulp wool-viscose fibre insulation 2 is sucked withblowers viscose gauze 11 onto which it is glued. The negative pressures produced by theblowers suction boxes wire 4. The arrows show the direction of flow. Arotary brush 17 flattens out the thickness of theinsulation layer 18. Anupper viscose gauze 19 is supplied onto theinsulation layer 18 fromroller 20 with ascreen conveyor 21. Wire 22 presses theviscose gauze 19 onto of theinsulation layer 18, and the fabric is glued with adhesive sprayed from the sprayingnozzle 10. The adhesive is a cellulose-based adhesive. The wire 22 is located betweenrolls 23. Air is circulated with ablower 24 through theinsulation layer 18, thus effecting drying. The arrows show the flows insupply box 25 andsuction box 26. In the flow direction, acondenser unit 28 wherewith water is separated from the air flow and aheater unit 29 heating the drying air are located incirculation conduit 27. The completedinsulating board 30 is supplied torollers 31 for packaging. - Figure 2 shows the insulation of an element with a cellulosic pulp wool insulation and the apparatus employed for the work, which has the same operating principle as the preceding embodiment.
Reference 32 denotes a blower through which the cellulosic pulp wool-viscose fibre insulation 33 is fed into afeed funnel 34.Frame 35 for the element is assembled on table 36, wherefrom theframe 35 is transferred onto apivoted wire member 37 beneath thefeed funnel 34. The wire is denoted byreference 38 and the suction box beneath it byreference numeral 39. A negative pressure is sucked with ablower 40 beneath thewire 38, and the insulation layer for the element will be smoothed. Arotary valve 42 and a low-pressure chamber 43 are provided inconduit 41, by means of which a pulsating negative pressure is generated in thesuction box 39. With the pulsating negative pressure, compacting of the cellulosic pulp wool insulation can be enhanced. Arotary brush 44 moves reciprocally upon theframe 35 of the element and evens out the insulation layer. Extra insulation is sucked away withblower 45 alongconduit 46 and is returned throughblower 32 intoconduit 47 for reuse. Once the insulation has been effected, thefeed funnel 34 is lifted away and a lid is nailed or otherwise attached onto the frame of the element. Thereafter theframe 35 of the element is turned onto table 49 with thewire member 37 supported by pivot 48 for attachment of a bottom sheet, whereafter the insulation of the element is complete. - The insulation method of the invention operates as follows. An insulation based on cellulosic pulp wool with which viscose fibres or equivalent are admixed is distributed onto a wire with compressed air. With a negative pressure provided beneath the wire, the insulation layer is sucked into a smooth, homogeneous and resilient layer. By adapting the negative pressure to be pulsating, the compacting can be enhanced. The thickness of the insulation is evened out with a rotary brush, and extra insulation is removed. With the apparatus shown in Figure 1, insulating
board 30 is produced in a continuous process. Cellulosic pulp wool-viscose fibre insulation 2 is blown onto aviscose gauze 11 laid on top ofwire 4. Adhesive is sprayed throughnozzles 10 into theinsulation layer 18, and thus the insulation material adheres to thegauze 11. The insulation layer is cut ondistribution conveyor 7 with pushers 9. Theinsulation layer 18 is evened out with arotary brush 17, adhesive is sprayed onto the insulation layer withnozzles 10, and anupper viscose gauze 19 is glued on top. The wet insulatingboard 30 is dried with hot, dried air blown through theboard 30. Air is circulated intocondenser units 28 provided inconduit 27 and throughheater unit 29 withblower 24. A heat pump may also be used for the task. The completed insulatingboard 30 is removed onrollers 31 for packaging. - In a second embodiment shown in Figure 2, insulation of a building element operates in principle as a batch process, one element at a time. The
frame 35 of the element is assembled on table 36 and is transferred for insulation onto awire member 37.Funnel 34 is lowered on top of thewire member 37. The negative pressure provided in thesuction box 39 beneath thewire 38 will even out the insulation layer (cellulosic pulp wool and viscose) into all locations, also the corners. A vibration effect is produced in the insulation layer by a pulsating negative pressure, produced byrotary valve 42 provided induct 41. Low-pressure chamber 43 intensifies the effect of the pressure impact. The pulsating negative pressure reduces the power requirement forblower 40. The insulation layer is evened out with a vertically adjustable, reciprocally movingrotary brush 44. Extra insulation is sucked away withblower 45.Feed funnel 34 is lifted into its uppermost position;conduits frame 35; adhesive can be applied to the lid, or adhesive can be sprayed on top of the insulation. Theframe 35 is turned on table 49 with the pivotable wire member, and the same operation is repeated for the bottom. - It is obvious to one skilled in the art that the insulation method of the invention can be implemented in a wide variety of applications. The amount of adhesive and bonding fibres may be varied. Also the location and number of the
adhesive spray nozzles 10 may vary. Different conveyor and transfer solutions are naturally also possible. The surface materials of the insulating board may vary, or they may be entirely omitted. Also thebrushes - Next, the structure of a
planar insulation product 430 will be set forth with reference to Figures 3-4. Figure 3 shows an insulatingboard 430. The insulating board includes twowide side planes board 430 comprises abase material insulation product 430 further comprises abonding agent cellulosic pulp wool reference 440 denoting the middlemost bonding agent and the middle adhesive layer has two meanings, as the bonding agent and the adhesive may be in combination for example in such a way that viscose glue or other cellulose glue that is fiberized upon drying and thus forms a bonding structure, i.e. a supporting structure, is employed as the adhesive. However,viscose mesh cellulosic chips adhesive - In the invention, besides the cellulosic pulp wool also the bonding agent and the adhesive are of a cellulose-based material, since in such a case all materials of the insulation are based on the same material, and hence the heat and moisture transfer capacity of the bonding agent and of the adhesive are the same as with the base material, i.e. cellulosic pulp wool, thus improving the properties of the insulation. Viscose fibre is employed as a bonding agent, since it is a cellulose-based material and since it has a good insulating capacity. The viscose fibre employed as a bonding agent in the insulation product is viscose yarn,
viscose mesh uppermost bonding agent 439 and thelowermost bonding agent 441 are of viscose mesh, because this provides a good bonding structure, i.e. supporting structure, which supports thecellulosic pulp wool insulation product 430. Viscose meshes 439, 441 also give a neat outer surface that withstands handling. - The adhesive 442, 440, 443 employed in the manufacture of the insulation product is a cellulose-based adhesive, preferably viscose glue, cmc glue or equivalent. Specifically between the layers of
cellulosic pulp wool bonding agent 440, made of viscose glue serves two purposes. Also theupper adhesive 443 and lower adhesive 442 can be contemplated to have two purposes, that is, they form viscose fibre upon drying and hence contribute to making up the bonding structure, i.e. supporting structure, and on the other hand adhere the fibres thereof and also the fibres of the viscose meshes 439, 441 to thecellulosic pulp wool - At its simplest, the insulation material between the side planes 431, 432 could comprise cellulosic pulp wool into which viscose glue has been sprayed or otherwise introduced, as in that case fibre and also adhesive wherewith the fibre and the cellulosic pulp wool are adhered to one another are simultaneously introduced into the insulation.
- The insulation shown in Figures 3-4 is thus a planar insulating
board 430, comprising twowide side planes bonding agent Cellulosic pulp wool Adhesive 442 is provided betweenviscose mesh 439 andcellulosic pulp wool 437. Likewise, adhesive 443 is provided betweenviscose mesh 441 andcellulosic pulp wool 438. - In a preferred embodiment, viscose fibre is also provided between the viscose meshes 439, 441 among the cellulosic pulp wool. This can be achieved for example with
layer 440. Said structure can also be produced in such a way that for instance viscose yarn is introduced into thecellulosic pulp wool pulp wool layer reference 450. By adjusting the amount ofviscose fibres 450 to be laid in the area between the side planes 431, 432, i.e. in the area between the viscose meshes 439, 441, and by adjusting the amount of adhesive to be employed in connection with the viscose fibres, insulation products of varying grades of hardness can be produced. - In an embodiment of the invention, a planar insulating
board 430 is produced. A viscose mesh made of viscose fibres is employed as abonding agent adhesive layers - Referring now to Figures 3-4, manufacture of a planar insulation product, i.e. the first embodiment of the invention, is set forth. Implementing the apparatus of Figure 1, the insulating board of Figure 3 has been produced in such a way that in the
method adhesive 442, preferably viscose glue or other cellulose glue, is applied to afirst viscose mesh 439, i.e.bonding agent 439. The next step is to form a cellulosicpulp wool layer 437, i.e. a cellulosic pulp chip layer, on top of the adhesive 442. In that connection,viscose yarn 450 can be admixed with thecellulosic pulp layer 437 with adhesive to serve as a reinforcement, as stated in the foregoing. This is achieved in such a way that viscosefibre 450 treated with adhesive is admixed with thecellulosic pulp wool 437 and/or 438 that will be located between the viscose meshes 439, 441. As a next step, adhesive 440, which will thus also serve as a bonding agent between the layers ofcellulosic pulp wool cellulosic pulp wool 437. The next step is the forming of a cellulosicpulp wool layer 438, i.e. cellulosic pulp chip layer, upon the adhesive 440. As a next step, asecond viscose mesh 441 is laid on top of theadhesive layer 443 as abonding agent 441. The next step is cutting to size of the continuous insulation band with an actuator, into an insulatingboard 430 having a given length. - Figure 4 shows a step in which the ends 433-436 of the insulation product are coated by means of an
actuator 460. In a preferred embodiment, the insulation product thus comprises ends 433-436 coated with adhesive, preferably a cellulose-based adhesive, such as viscose glue, and hence the insulation will withstand handling and have better properties. The coating is preferably performed after the cutting, to enable coating of the ends of theinsulation product 430 transverse to the production line simultaneously with the lateral ends of the insulation that have the direction of the production line. - Figures 5-7 illustrate another embodiment of the invention. Figures 5-7 show a
building element 100, such as awall element 100. The building element comprisesposts 101 of a frame structure, providing the frame of the building element. The building element further comprisesboards reference 130. In Figures 5-6, the building element comprises fiveframe posts 101, and thus the element comprises four compartments 104-107, the twoleftmost compartments third compartment 106 is presently being filled, and thefourth compartment 107 is still empty. In Figure 5, the element is not shown entirely but is shown with the upper edge cut away. - In the second embodiment of the invention, the
insulation 130 is an insulation formed within the encasedbuilding element 100. - In the second embodiment of the invention in Figures 5-7, the apparatus comprises a
production line 201 upon which the insulation is built into the element. The production line comprises forinstance conveyor belts 202 rotating betweenrolls 203 and producing a leftward movement in the direction of arrow C i Figure 6. The apparatus further comprises anactuator 210 wherewith the materials employed in the production of theinsulation 130 can be blown in or otherwise introduced into theelement 100. Theactuator 210 comprises atransfer element 211 wherewith theactuator 210 can be transferred both in the longitudinal and in the transverse direction relative to theelement 100 and the production line, in order for theinsulation 130 to fill the inner space of theelement 100 as well as possible, also the possible dead spaces. In Figure 5, the apparatus also comprises a compactingmember 700 wherewith the insulation material blown into the building element can be compacted still further. The apparatus also comprises afeeding device 800 through which the materials can be fed into theactuator 210. - Both the first and the second embodiment involve a method for manufacturing an
insulation product insulation product - In a preferred embodiment, viscose fibre or other cellulose-based bonding agent is employed as a bonding agent in the manufacture of the insulation product, such as 430, 130. Likewise, a cellulose-based adhesive, such as viscose glue, cmc glue or equivalent, that becomes fiberized upon drying is employed as an adhesive, and thus in simple versions of the invention no separate bonding agent, such as viscose yarn, need be employed, though the advantages of the invention are enhanced with the use of viscose yarn or other solid viscose fibre or an equivalent cellulosic fibre.
- In Figures 5-7, the base material, i.e. the cellulosic pulp wool or cellulosic pulp chips, is denoted by
reference 237, the bonding agent, such as viscose yarn, is denoted byreference 239, and the adhesive, such as viscose glue or other cellulose glue, is denoted byreference 240. - In Figure 7, the
actuator 210 is such that it comprises afeeding device 212, such as ascrew conveyor 212, for feedingcellulosic pulp wool 237, asecond feeding device 213 for feedingbonding agent 239, such asviscose fibre 239, and athird feeding device 214 for feeding adhesive 240, such asviscose glue 240. Theactuator 210 incorporates arotary nozzle 210a centrally at the end ofscrew 212, through which nozzle thebonding agent 239 and adhesive 240 are fed, simultaneously rotating thenozzle 210a. Herein the method is preferably such that thebonding agent 239 and adhesive 240 are fed into the centre of the cellulosicpulp wool flow 237 in such a way that the flow ofbonding agent 239, i.e.fibre flow 239, and the flow of adhesive 240 are rotated, which makes the materials to become scattered/distributed effectively. - The second embodiment of the invention in Figures 5-7 thus relates to the fact that in the method an
insulation 130 is produced within thebuilding element 100. The base material for theinsulation 130 is formed fromcellulosic pulp wool 237. Abonding agent 239, such asviscose fibre 239 in the form of a long or shorter yarn, to which the cellulosic pulp wool is bonded by adhesive 240 also applied in the method, is employed to produce the insulation. At its simplest, the method is such that thebonding agent 239, such asviscose yarn 239, is treated with adhesive 240 prior to its being blown into thecellulosic pulp wool 237. Thefibre 239 is cut at thenozzle 210a. - The
actuator element 100 or vice versa, and thus theactuator bonding agent 239, utilizing adhesive 240, into thecellulosic pulp wool 237. - In Figures 5-7, initially adhesive 240 is applied to the interior of the
building element 100, whereaftercellulosic pulp wool 237,bonding agent 239 and adhesive 240 are blown substantially simultaneously into thebuilding element 100 with theactuator - The initial application of adhesive to the empty element has the result that the
insulation 130 comprisesbonding sites 400 between thebuilding element 100 and theinsulation 130, which will prevent settling of theinsulation 130 even better than heretofore. - Since compressed air is used for blowing the materials into the
element 100, the overpressure, i.e. circulated air, must be removed using the same flow path and evacuation means 500. Cellulosic pulp wool dust can be collected from the circulated air and reused when necessary. - Also the embodiment of Figures 5-7 can utilize the arrangement of Figure 2, in which an air-pervious wire and negative pressure suction are used. In that case, the procedure is such that the
boards - Even though the invention has been described in the foregoing with reference to examples in accordance with the accompanying drawings, it is obvious that the invention is not restricted to them, but it can be modified in a variety of ways within the scope of the inventive idea as defined by the attached claims.

- A method as claimed in claim 12, characterized in that the air drying of the insulating board (30) forms a closed circulation loop (24, 25, 26, 27, 28, 29).
- A method as claimed in claim 8, characterized in that to compact the upper surface of the insulation, extra thickness is left which is compacted by compression by a wire, air pressure, a sheet/slab or an equivalent method.
- A method as claimed in claim 6, characterized in that a planar insulating board (430) is produced in the process, and that a viscose mesh (439, 441) formed from viscose fibres is employed as the bonding agent, that in the process a first viscose mesh (439) is laid onto the production line for insulation, adhesive (440) and cellulosic pulp wool (437) are applied on top of this mesh, on top of which adhesive is again applied, on top of which a second viscose mesh (441) is applied.
- A method as claimed in claim 15, characterized in that adhesive and viscose fibre (450, 440) are admixed with the cellulosic pulp wool (437) that will be located between the viscose meshes (439, 441).
- A method as claimed in claim 6, in which building elements or equivalent are insulated, and the method employs an apparatus that comprises feeding devices (32, 47) for insulation (33), blowers (32, 40, 45), tables (36, 49), a feed funnel (34) and a wire member (38), characterized in that an element frame (35) assembled on table (36) is fitted on the wire member (37), the negative pressure of a suction box (39) beneath the wire member distributing the insulation (33), and that the negative pressure is adapted to be pulsating by means of a rotary valve (42) disposed in conduit (41) and a low-pressure chamber (43).
- A method as claimed in claim 17, characterized in that the method employs an apparatus in which the feed funnel (34) can be lifted up, and that the wire member (37) is articulated with a joint (48) to be turnable onto table (49) in order that a bottom sheet and a lid may be attached to the element frame (35).
