Description

Plates shaped bodies o bonded mineral and their manufacture The relates to the manufacture of a or piece of mineral for example glass bonded by a binding and which possess both good thermal insulation properties and good resistance to According to this invention a process for making a mat or piece of mineral comprises the steps moving stream of mineral fibres directly to collecting where the fibres are collected as of causing a sheet of solid particles to flow by gravity substantially homogeneously and at a constant the particles of the sheet into the moving stream fibres means of a gaseous current so thatthe particles are distributed substantially homogeneously in the stream before it reaches the collecting spraying a thermosetting binding agent on to the fibres or the particles or before they reaoh the collecting and causing the volume of the collected mass of fibres to be reduced whereby the particles are distributed substantially homogeneously enclosed in the fibres on setting of the binding It has been that a mat or piece made by this while showing a slight ability to especially whe subject to conserves to a great exten the insulating pertiea inherent in the fibrous structure of the This servation of insulating properties is due to the fact that the are not in oontact with the fibres except for point tact or oontaot along a short so that there is little These products resistance to tion because each particle prevents local deformation of the With uniform distributio of the particles throughout the deformation of the entire mass is prevented by presence of the In a general it is convenient to choose the average granular siae of the particles employed in terms of the apparent density of the fibrous The size of the particles must be such that they are enclosed within the formed by the fibrous If the fibres are very particles of granular sizes are if particles o larger granular size arcs The may have an average diameter of from to 16 the apparent density of the mass may be from 25 to 200 Kg per m and preferably from to 100 Kg per m the granular size of the particles may be from to and the proportion by volume of the partiqles 2 to from of the total volume of the The particles may for grains of sand of a grain size of from to Instead ofsahd particles of ground pulverised rock or slag may be Some or all of the binding agent may be introduced with the Thus better distribution of the binding agent the fibres It has been found that binding agent i introduced with the particles migrates from the surface of the particles towards the fibres and ensures bonding of the fibres at the points of intersection substantially without binding remaining at the points of contact between particles and fibres formation of thermal bridges between them are thus The invention also includes made by the process of the The invention also includes apparatus for making mat or The particles may include some Suc particles are preferably mineral and for example perlite or Products made with such particles are in and have good insulatin efficiency and good resistance to has been found in case of a fibrous mass having a slightly increased specific the presence of such particularly permits one to obtain good resistance to especially In using such the fibres preferably have an average diameter of from 3 to 16 the apparent density of the being from 8 to 80 K and preferably from 8 to 50 Kg per m the grain size of the particles being greater than and preferably from to and the proportion by volume of the particles being from 3 to and preferably from 10 to of the total volume of the The quantity of the particles used per unit volume of the produot depends on the density of the product the mechanioa properties for example resistance to It is advisable that the proportion of particles be greater as the fibrous constituents per unit volume is fop same quantity of fibres per unit volumes more particles used than are neededto obtain greater mechanical the stream of fibres is a rotating tubular the particles may into the curtain with a movement having a in the opposite direction to that of the rotation of the 1 is a diagram of a

If the mass is subjected to compression its thickness diminishes and the quadrilateral A B becomes the quadrilateral of Figure Figure 3 shows the same mass of but in which particles are enclosed between fibres as The former intersection now seen at up practically same relative positions as in If the mass is subjected to the same compression as before the presence of the particles 2 prevents deformation the mass in which they are points remain in the same position as points and the mass less reduced i thickness than in Figure In embodiment shown Figures 5 and 6 particles 12 are distributed an annular hopper 16 coaxial with the stream of fibres 2A produced by a spinner Feed of the particles is adjusted by regulating devices The particles flow by gravity at a constant rate and tho a sheet from an annular aperture 19 of the which sheet is acted on by an annular blower which provides for substantially geneous distribution of the particles throughout the stream of fibres Below the blower 20 is tubular vertical duot 21 through which the stream fibres passes and which given an oscillatory movement to cause uniform of the falling directly on to collecting means in the form of a conveyor belt The mass of fibres with particles distributed stantially homogeneously therein is compressed in known manner to reduce its The particles are thus enolosed the fibres on setting of the binding thermosetting binding agent is sprayed into the stream of fibres and particles by guns Alternatively some or all of the binding agent can be sprayed onto the fibres along oh to particles Referring to Figure a spinner 117 of wellknown kind duces a stream of fibres In the embodiment of Figures 7 to sand particles be introduced into the stream of fibres are fed to two hoppers 130 whence they flow tubular conduits each conduit 131 is a conveyor screw see also Figure The 132 are synchronously from a motor The bottom of each conduit 131 has orifices through which flow the particles fed

Thei direction is such that zones of impact 137 permit formation of a continuous and homogeneous sheet as referred to mounted on supports 146 arranged directly in line with the distributor annulus so as to limit to a minimum the space requirement of the The arrangement and rotational speed of screws 132 are such that a layer of particles of substantially constant thickness is obtained above the assembly of orifices 133 to obtain desired flow for each chute masks 147 12 and are arranged around each conduit 131 and holes 148 of different the masks being mounted above the chutes and in such manner that each can be turned to opposite an exit orifice 133 on the hole corresponding the flow A stop 149 on each mask cooperates with any one of several notches 150 of the conduit 131 for correct placing of the mask for each hole To allow discharge of surplus particles and to avoid blockages in the overflow openings 151 for removal of the surplus particles are arranged at the ends 152 of the oonduits The quantity of particles discharged by the distributor is a function of the diameter of the holes 148 of the masks 147 and of the speed of rotation of the screws the latter being adjusted so that all the holes discharge except the overflow openings The latter only discharge in the case of blocking of the holes or wrong thus avoiding damage to the the modified form of apparatus shown in
