Definitions

  • This invention relates to a method of manufacturing insulating boards composed of interconnected rod-shaped mineral fibre elements (in the following referred to as lamellae) comprising converting a melt of a mineral fibre forming starting material into fibres, supplying a binder to said fibres, causing the fibres to form a fibre web, cutting the fibre web in the longitudinal direction to form lamellae, cutting said lamellae into desired lengths, turning the lamellae 90 ⁇ about their longitudinal axis and bonding them together to form boards.
  • lamellae interconnected rod-shaped mineral fibre elements
  • a method of the type defined above is disclosed in DE patent publication No. 2307577 C3.
  • the melt is converted into fine mineral fibres by being thrown out from one or more rapidly rotating spinning wheels under the simultaneous supply of a binder capable of being cured, and the fibres thus formed are caught on an endless belt in the form of a fibre web wherein the fibres predominantly are oriented parallel to the surface of the web.
  • the fibre web is cut longitudinally into lamellae and the lamellae thus formed are turned 90" about their longitudinal axis whereafter the lamellae thus oriented are bonded together to form a web-like product which is then cut into desired lengths to form board elements.
  • Boards produced by the method described above are suitable for many applications, but for certain applications, e.g. exterior insulation of roofs and/or building fronts and insulation of floors, the boards possess an insufficient stiffness or strength and/or insulating property.
  • the invention is based on the discovery that a compression in the longitudinal direction of a fibre web, in which the fibres are predominantly oriented parallel to the surface of the web, produces an inner fold structure in the fibre web, the folds extending perpendicularly to the longitudinal direction of the fibre web.
  • each lamella When such a web is cut longitudinally into lamellae and the lamellae are turned 90° and bonded together to form a lamella board, each lamella will exhibit a folded layer structure, the folds extending perpendicularly to the main surfaces of the lamella board and thereby imparting a greater stiffness and strength (area strength) to the lamella board than in the case where a lamella board is composed of rectilinear layers.
  • a relatively thick mineral fibre web can be formed directly, viz. by collecting the fibres made from the melt on a conveyor belt, see DE patent publication No. 2307577. It is also well known that a fibre web can be produced by initially producing a relatively thin primary web and subsequently doubling the primary web to form a secondary relatively thick fibre web comprising partially overlapping layers of the primary web, see DE patent publication No. 3501897.
  • the fibres In a fibre web which is formed directly on a conveyor belt the fibres have varying directions of orientation, but by subjecting such a web to a surface compression the fibres will be partially re-arranged so as to be predominantly oriented in a direction which is parallel to the surface of the web.
  • the fibres are collected on a high-velocity conveyor belt, e.g. running with a velocity of 130 m/min, in the form of a thin fibre layer, e.g. having a weight of
  • the secondary fibre web is formed by laying by means of pendulum belts the thin primary web in a number of layers, e.g. 20, preferably transversely to the longitudinal direction of the secondary web, the number of layers being determined by the desired area weight of the secondary web.
  • the fibres are predominantly oriented transversely to the web when the layers of the primary web extend transversely to the secondary web.
  • the purpose of doubling a fibre web is ordinarily to obtain a secondary web having a relatively great thickness and having a small variation in density in the longitudinal direction.
  • lamellae made from a doubled fibre web comprising from 4 to 25 layers and having a surface weight of from 1 to 8 kg/m 2 are preferably used.
  • a particularly high compression stiffness is obtained with boards made from lamellae obtained by cutting a secondary web longitudinally and subsequently turning them 90° about their longitudinal axis because the fibres being predominantly oriented transversely to the secondary web will be positioned perpendicularly to the plane of the board.
  • the longitudinal compression may also be effected when the web has been cut into lamellae.
  • lamellae made from fibre webs which have been compressed longitudinally in a ratio of from 1.5:1 to 4:1 are preferred.
  • the longitudinal compression should be effected following the vertical compression and when using a heat curable binder, the said longitudinal compression is effected before the fibre web is introduced into a curing furnace.
  • Methods for subjecting a fibre web to a surface compression are also well known.
  • the fibre web to be compressed is introduced into the space between the rollers in a series of roller sets, the spacing between the rollers in the roller sets decreasing in the direction of movement of the fibre web.
  • lamellae made from a fibre web which has been surface compressed in a ratio of from 3:1 to 6:1 are preferred.
  • the cutting of the fibre web to form lamellae is preferably effected by means of saws which may have the form of compass saws, cf. DE patent publication No. 2307577, or circular saws, cf. SE published patent application No. 441764 and DE patent publication No. 2032624.
  • the rod-shaped fibre elements are cut into desired lengths before being turned 90" and combined into lamella boards.
  • Such turning may e.g. be effected in connection with the transfer of the cut lamellae from one conveyor belt upon which they are advanced in the longitudinal direction of the lamellae onto another conveyor belt moving perpendicularly to the first belt and upon which the lamellae are conveyed in a direction perpendicularly to their longitudinal direction.
  • This embodiment is advantageous in that the apparatus used for such turning of the lamellae requires little space.
  • the turning of the lamellae can be effected during the cutting of the web into lamellae, e.g. as described in DE patent publication No. 2307577 or DE 2032624.
  • the properly oriented lamellae which are to form a lamella board can be glued together, preferably by means of a binder which is applied to the upper side of the fibre web and optionally to the lower side thereof, and preferably before the web is cut into lamellae.
  • the binders can be cured in one step by conveying the properly oriented and combined lamellae through a curing furnace in which they are heated to curing temperature, which is preferably between 210 and 260 ⁇ C when phenol formaldehyd resin is used as a binder.
  • the binder for bonding together the lamellae may also be supplied after the fibre web/lamellae have been heated in a curing furnace to cure the binder supplied to the fibres in connection with their formation.
  • FIG. 1 designates a furnace for manufacturing a mineral fibre forming melt which is supplied to a spinner 3 having four rapidly rotating spinning wheels 4 via a melt outlet 2.
  • the lower ends of the pendulum belts are located pivotally in a direction perpendicularly to the direction of movement of a further endless conveyor belt 12 which is supported by two rollers 13, one of which is driven by driving means (not shown).
  • the amplitude of the oscillation of the lower part of the pendulum belts 10 and 11 corresponds to the width of the conveyor belt 12 and a doubled fibre web 14 of partially overlapping fibre layers 8 is thus formed on the belt 12.
  • the fibre web 14 is subsequently introduced into a surface compression section consisting of three sets of co-operating rollers 15, 16 and 17, the spacing between the rollers in the roller sets decreasing in the longitudinal direction of the fibre web. Subsequently the fibre web 14 is introduced into the longitudinal compression section which also consists of three roller sets 18, 19 and 20, the rollers of the latter sets of rollers rotating with the same velocity, which velocity is lower than that of the sets of rollers 15, 16 and 17.
  • the fibre web which has been compressed longitudinally is then introduced into a curing furnace 21 in which it is heated to a temperature which is sufficiently high to cure the binder and to fix the fibres relatively to one another.
  • the heat treated fibre web 14 is cut in the longitudinal direction by means of saws 22 so as to form lamellae 23 which are subsequently cut transversely by means of a transverse saw 24.
  • the lamellae 23 thus cut are then turned 90 ⁇ and combined to form a board element 25 on a conveyor belt 26 and at the same time a binder is applied to the contact surfaces by means of an application apparatus (not shown) to bond together the lamellae 23.
  • the fibre layers formed from the primary web 8 extend substantially perpendicularly to the surface of the finished board element, and as they are also folded they are highly resistant against compression.
  • the lamellae can be joined together by means of e.g. strips, strings, vlies or paper on one side or both sides of the boards.
