Definitions

  • This invention relates to bonded man-made vitreous fibre (MMVF) batts which may be of relatively low density (such as 5 to 50kg/m 3 ) and in particular to elongated pieces cut from such batts and supplied to the user as a compressed packaged roll.
  • MMVF vitreous fibre
  • One conventional way of producing such batts involves fiberising mineral melt on a centrifugal spinning apparatus and thereby forming a cloud of fibres entrained in air, including curable binder in the cloud, carrying the cloud forwards from the spinner in a stream of air, collecting the cloud of fibres as a primary web on a substantially continuous moving collector, transporting the web to a cross-lapping position, cross-lapping a plurality of layers of the web while substantially continuously conveying the resultant continuous batt from the cross-lapping position, curing the binder by passing the batt through a curing oven and cutting the continuous batt into elongated pieces before, during or after curing, and compressing and packaging the elongated pieces of batt as rolls.
  • the continuous batt can be considered as having upper and lower faces which extend in the X and Y axes or directions with the X direction being the width of the batt as it is collected and the Y direction being the length of the continuous batt as it is collected and carried away from the cross lapping position.
  • the quality of the final product tends to deteriorate as the primary web increases in thickness, and so there is an incentive for the primary web to have reduced thickness.
  • reducing the thickness of the primary web results in reduced productivity (tons per hour) unless either the web is made wider than usual or the web is made to travel faster than usual.
  • the normal maximum width of the primary web is 2 metres, although widths of webs (made by other methods) of up to 2.5 metres are mentioned in DE 3501897 A and up to 4 metres in WO 99/51535 A.
  • Increasing the speed of travel of the web has the disadvantage of increasing the frequency of reciprocation of the cross lapping apparatus, and this causes engineering problems. It would be desirable to achieve increased productivity whilst minimising or avoiding these problems and whilst maintaining quality.
  • continuous bonded batt may be used in various forms, most continuous batt is converted into elongated pieces of batt usually having a length greater than the width.
  • the normal width of the continuous batt in the X direction is up to 2 metres (although a width of up to 2.5 metres is described in DE 3501897 for batts made by different fiberising techniques) with the result that the maximum length of pieces cut from the batt is normally 2 metres if the pieces are cut transversely, along the X direction.
  • the cut pieces usually have a shorter dimension in the Y direction and so have a width below 2 metres. Because the maximum length in the X direction is, in normal practice, 2 metres, this curtails the type of products which can be made by cutting in this direction. In particular, transverse cutting along the X direction cannot provide elongated pieces having a length above 2 metres.
  • the present invention simultaneously solves all these problems.
  • an elongated, bonded man-made vitreous fibre (MMVF) batt which has a length direction X and a width direction Y and which has upper and lower faces which extend in the X and Y direction and wherein the batt is formed of a compressed and cured intermeshed stack of layers each of which is formed of air laid MMVF primary web which includes a bonding agent and wherein, each layer is substantially parallel to the faces when viewed in cross section along the X direction, the layers are regularly displaced relative to each other in zig-zag fashion in the Y direction, and each layer is inclined to the faces when viewed in cross section along the Y direction, characterised in that the layers between the faces extend as continuous layers throughout the X direction, the length in the X direction is at least 3 metres and is greater than the width in the Y direction and the batt is in the form of a compressed and packaged roll whose axis extends in the Y direction.
  • MMVF vitreous fibre
  • the length of the batt in the X direction is at least 4 metres, for instance as much as 6 or even 8 metres.
  • the length in the X direction is usually at least two times longer than the width in the Y direction.
  • the products of the invention are made by fiberising mineral melt on a centrifugal fiberising apparatus and thereby forming a cloud of fibres entrained in air, including curable binder in the cloud, carrying the cloud forwards from the spinner in a stream of air, collecting the cloud of fibres as a web on a substantially continuously moving collector, transporting the web to a cross lapping position, cross lapping a plurality of layers of the web while substantially continuously conveying the resultant continuous batt away from the cross lapping position along the Y direction of the batt, curing the binder by passing the batt through a curing oven, and cutting the continuous batt along the X direction (transverse to the Y direction of the continuous batt) into pieces before, during or after curing, and packaging each piece as a compressed roll, and in this process the cross lapped continuous batt and each of the pieces has a length in the X direction of, and the width of the curing oven is, at least 3 metres and the width of each of the pieces in the Y direction is less than the
  • the cross lapping is conducted to produce a continuous batt which is wider (in the X direction) than usual, and in particular is at least 3 metres wide and often 4 metres up to 6 metres or even 8 metres wide, and this very wide batt is then cut transversely.
  • the length of the curing oven can be reduced.
  • increased production can be achieved by a fast primary web speed and a wide batt, without the need to increase the length of the curing oven unacceptably.
  • the curing oven merely needs to be made wider, and in many plants this is a significantly preferred option compared to increasing the length of the oven.
  • the batt is cut transversely to provide elongated pieces having a dimension in the X direction of at least 3 metres and generally at least 4 metres and with a lesser dimension in the Y direction, for instance up to 1 metre or 2 metres.
  • the product of the invention is a compressed and packaged roll which, when unwound, has better tensile strength in the length direction than conventional roll products having a length of at least 3 or 4 metres, since these conventional products have their major length extending in the Y direction.
  • the axis of the roll extends along the Y axis, ie. transverse to the length direction of the initial batt.
  • each piece may be rolled tight with plastic film trapped between the layers of the roll, at least towards the end of the piece, and then sealed to itself after rolling, thereby trapping the roll in an envelope of plastic film.
  • Other conventional methods of packaging the roll in its compressed state can be used.
  • the amount of compression of the roll is generally such that the thickness and volume of the roll is 10 to 50% of the norm volume of the batt.
  • the extent of compression is typically from about 50% to about 90% based on the volume of the batt.
  • the thickness is generally at least 50mm and usually at least 80 to 100mm. It is frequently up to 180 or 220mm and can be up to 250mm.
  • the thickness of the batt before being compressed and rolled is likewise usually within the range 50mm to 250mm. Usually the thickness before rolling and compression is 5 to 20%, often around 10%, more than the desired thickness after unrolling and equilibration.
  • thickness is determined by laying the product on a hard flat surface, laying a 200mm x 200mm pressure plate on the surface so as to apply a pressure of 50Pa and measuring the separation between the supporting surface and the plate.
  • the measured thickness is the average of values taken at a number of points .
  • the number of points is 5 when the roll is 2 metres long, 7 when 3 metres long and 9 when 4 metres long, with the points being distributed uniformly over the width of the roll but excluding the outer 150mm of the width.
  • the products of the invention usually have a nominal density of 5 to 50kg/m 3 , and generally at least 15 or 20kg/m 3 up to 40 or 45kg/m 3 .
  • the product after unrolling and equilibrating has a density in these ranges.
  • the density is derived by calculation from the thickness, measured as above, and measurements of the surface area of the unrolled material and its mass.
  • MMVF rolls of provide a tensile strength of 3 to 4kN/m 2 in the length direction (along the Y axis) (indexed to 30kg/m 3 density and ignition loss 1.4%) but in the invention typical values for slabs can be from 6 to 8 kN/m 2 in the length direction because the length direction is along the X direction during initial manufacture of the batt which is cut to provide the elongated pieces.
  • the primary web is as described in our application GB 0019999.2 filed 14 August 2000 and in our PCT application WO 01/23312 A filed even date herewith, wherein the primary web also has a width of, generally, at least 3 metres and preferably 4 to 8 metres.
  • the fibres are preferably made using one more centrifugal cascade spinners each comprising a first rotor and one or more subsequent rotors which rotate about the substantially horizontal axis and thereby form the cloud of fibres entrained in air.
  • Suitable apparatus and techniques for forming the fibres are described in, for instance, WO 92/06047 A, WO 92/12939 A, WO 92/12.940 A, -WO 96/38391 A and WO 99/51535 A.
  • three cascade spinners 1, 2 and 3 each having four rotors are located in an end wall of a spinning chamber shown diagrammatically as 6, and discussed in more detail below.
  • Melt is poured on to the top rotor in each spinner and is thereby fiberised in conventional manner into fibres which are carried forwards by primary air which is blasted forward as wall jets over the individual rotors and secondary air which is induced into the chamber around the spinners.
  • Suction is applied through a continuously moving collector 5, whereby the fibres are deposited as a web 7 which is carried to a cross lapper 8 by which the web is cross lapped on to a conveyor 9, thereby forming a batt 10 which is continuously conveyed away from the cross lapping position.
  • the conveyer 9 and the batt has a dimension X of at least 3 metres, usually 4 to 8 metres.
  • the batt 10 is passed through rollers or the like to compress it and cause intermeshing of the individual layers in the batt and is then passed through a curing oven to cure binder which is sprayed into the cloud of fibres from the cascade spinners 1, 2 and 3.
  • the collector 5 and the web 7 can be, for instance, 2 metres wide but are preferably 3 or 4 metres wide, up to 7 or 8 metres wide.
  • the angle of the collector 5. to the horizontal can be about 30°, as shown in the drawings, but is preferably 45 to 90°, often around 50 to 80°.
  • the collecting chamber is substantially closed as described in WO 96/38391 A.
  • the collector can be a cylindrical drum mounted with its axis transverse to the direction of travel of the web. Instead of travelling away from the spinners, the collector can travel towards the spinners for instance as described in WO 01/23314 A.
  • FIG 2 shows the construction of the batt in more detail.
  • the batt has upper and lower faces 30 and 31. It has an end edge 32 formed by cutting the batt transversely and thus exposing the cross section along the X direction. It has side edges 33 and 34 formed in Figure 3 by the edges of the cross lapping. When the batt is cut along the Y direction the cut side edges will show the same inclined arrangement of layers as is apparent in the edges of the batt formed by cross lapping.
  • the end edges 32 extend in the X direction and the side edges 33 and 34 extend in the Y direction.
  • the web 7 is cross lapped in the X direction as the conveyor 9 travels under the conveying position.
  • the end edges 35 in the cut end edge 32 are substantially parallel to the faces 30 and 31 whilst the uncut edges 36 of the layers extend between the side edges 33 and 34 at substantially regularly spaced apart positions, in a zig zag pattern.
  • Figure 3 is an end view of a roll and shows the edge 32 of the rolled and compressed batt held compressed in the roll by plastic wrapping 37 which is interleaved in the roll and secured on itself at position 37, so as to hold the roll in its compressed rolled configuration.
  • the conveyor 9 carries the batt through a curing oven which can be a conventional construction except that it has to be at least as wide as X.
  • the conveyor also carries the batt through conventional cutting systems and rolling systems so as to cut the continuous batt into elongated strips which may have a length of X (more than 3 metres) and a width which is usually less than this.
