Definitions

  • This invention relates to caterpillar presses of the character described in British patent specification No. 595,423 (of which the present company are copatentees) for the manufacture, under heat and pressure, in continuous web or long sheet form of wallboard, sheeting or panelling or like material (hereinafter called wallboard) having a large surface area in relation to thickness, an aim of the invention being to provide a machine essentially capable of manufacturing such wallboard from a, mixture of a discrete filler, such as sawdust or other comminuted fibrous or cellulosic or other material bound with a thermo-setting plastic, in such a manner that the product is of uniform gauge throughout Without waves or zones of overcompression or transverse surface marks.
  • a discrete filler such as sawdust or other comminuted fibrous or cellulosic or other material bound with a thermo-setting plastic
  • the invention is directed tothe solution of this problem by adoptinga positioning of the rollers of the upper chain (assuming it tobe the chain which turns into the rectilinear path in the said squeezing zone) with their axes over the junctions between the platens and providing arunning rail or bed form for the rollers at the squeez ing zone which constrains the platens in turning into the rectilinear path to travel on an arc or curvature of such radiusthat the flexure of the band as it is flattenedin the squeezing zone I against the angularly disposed faces.
  • the gap between the platens in making said turn is well within the elastic limit, and further thatthe gap between the platens in making said turn is such that on the one hand, the band in the locality assumes a convex curve which is within the critical capacity of recovery to bending of the metal, and on the other, is capable of supporting the reactive pressure of the material.
  • it. is essential according to the invention to arrange the linkage of the platens so as to provide a gap between adjacent platen edges when in the rectilinear position such that the band lies across it with insignificant concave deflection, while at the critical turning point in the squeezing zone, the gap widens to allow a free bowing of the band about a radius well within the elastic limit of the metal.
  • the existence of the gap between platen edges, in the rectilinear run also accommodates heat expansion and debris which, if collected between platen edges, would set up undue strain under the pressure.
  • the gapping may. beprovided by amply radiusing the platen edges with a clearance m rear which is merely sufficient to accommodate debris and allow for expansionj
  • the invention also comprises a composite roller platen link band or chain havi'n'ga, senes'srtransverse sets of links each link of wlii hjbe'ars" a roller at each end, the sets bein connected to: gether by intermediate sets of plain linksalterating transversely.
  • the above form of chain is employed for that chain (preferably the upper one) the platens of which turn into the rectilinear path in the said squeezing zone, while the other chain may have the same characteristics, but since its platens can assume the rectilinear path before entering the squeezing zone the precautions referred to above are not so important.
  • the platens of this other (lower) chain are conveniently provided at their outward ends with upstanding flanges to provide, when the chain is running in the rectilinear path, continuous deckle edges within which the metal bands and the platens in the pressure lap of the first-mentioned chain are housed.
  • the lower bed is mounted as a fixture and the upper bed and chain is mounted for vertical displacement, and this arrangement will be assumed for the purpose of further description and exempliflcation of the invention.
  • a backing or running bed for the upper chain is floatably mounted for vertical displacement and equalised pressure is brought to bear throughout the pressure lap hydraulically to effect such displacement.
  • the bed comprises a series of massive transverse beams carrying a set of inverted rails corresponding with and acting as running tracks for the link rollers suspended from the pistons of hydraulic cylinders in hydraulic communication one with another and connected to a common pressure source.
  • the bed for the lower lap may be of similar massive transverse beam and rail construction and it is preferred that the beds should operate in opposed relation by mounting the beams between the jaws of massive vertical brackets located at the sides of the pressure lap so that such brackets under pressure function in tension.
  • the machine according to the invention may be built to operate on a prepared mat of material fed on the lower band to the pressure lap, according to one or other, or alternatively either, of the modes hereunder:
  • thermosetting binder such as phenol formaldehyde or urea formaldehyde

  • Figure 9 is an end elevation of the arrangement shown in Figure 7 giving a side elevation of one of the transverse supporting beams.
  • a suitable foundation is provided on which are mounted two sets of massive brackets I, a set being located at each side of the machine. These brackets each have an inwardly projecting foot 2 and an inwardly overhanging head 3, the sets being positioned in pairs facing one another. The upper ends of the pairs of brackets are tied across by transverse girders 4.
  • each pair of brackets l Extending between and supported upon the foot portions of each pair of brackets l is a massive beam (or beams) 5 for supporting a bed 6 over which runs the active or pressure lap of the lower of two endless chains A and B of pressure applying platens l8 and 20.
  • Similar but inverted beam members 1 are provided for the upper bed or abutment 8 for the platens of the pressure lap of the upper endless chain A of platens [9.
  • These upper beams l are mounted for displacement under the pressing operation towards the lower bed and are suitably guided at their outer end in vertical slideway members 9 which may conveniently be mounted on the inner sides of the brackets I.
  • the beams l are slung from or acted upon towards each end by the pistons ill of hydraulic cylinders l I carried at the underside of the bracket heads 3.
  • the beams l are connected in pairs by bridge members 10, the hydraulic cylinder pistons It! being applied centrally of the bridge members; thus eight beam members are served by four hydraulic cylinders II on each side corresponding with each set of brackets I (see Figure 2).
  • the pressure beds 6 and 8 are formed by massive longitudinal rails 12 and I3, such being adopted for the beds as the most suitable form of construction for co-operation with stout running or anti-friction rollers M with which the platen chains A and B are provided as described hereafter.
  • the rails l2 and I3 may be provided with hardened wear faces H and 12 with which the rollers l 4 have contact.
  • the board-forming material' E is treated between: lower. and. upper endless metal bands D and F which passbetween the active horizontal .and parallel laps; of the lower and upper platen. chains A and B.
  • the platens l9 are carried by a composite link chain to overcome certain diificulties in manufacture.
  • These composite link chains each comprise a series of transverse sets of rollered links 2
  • the sets of plain links 22 are located longitudinally betweenthe sets of rollered links 2
  • the pins or spindles, 23 do not extend across the whole width of the platen chain, but only across three widths of links as shown as a. group in Figure 5; in this way any transverse flexure of the platen chains does not cause binding between the pins or spindles 23 and their associated links 2
  • each comprise a link, body 24 (see Figure 5.), towards the ends of which leg members 25 project toward the interior of the endless laps of the chain.
  • bearings 26 are formed for the trunnions or spindles 21, of the stout rollers It. (see Figures 4 and 6).
  • the rollers M are mounted in the transverse intervals between the rollered links 2
  • the axes of the rollers I4 and the axes of the link pivots 23 lie substantially inv the transverse plane at the junction between the links.
  • has a sprocket recess 28 for driving engagement by sprocket teeth 29 of the chain wheel assemblies I5.
  • the chain wheel assemblies l5 each comprise a series of sprocket toothed discs 30 spaced on their shaft l6 in planes aligned with the longitudinal planes of the sets of rollered links 2
  • and 22 has transversely extending (from side to side of the pressure bed) the platen plates it of. heavy gauge welded or otherwise secured to and transversely bridging the links so that each set of rollered and plain links becomes an integral unit with its platen plate IS.
  • a heat insulating layer may be interposed between the platens and the links of the chain i order to increase thealife: of. the chain bearings.
  • The, width.'(i;.e.'the dimension taken longitudinally of: the. machine) of the laten plates l9, more particularly those of the upper chain A, should be: made as short as constructionally convenient in order to conform to. the radius of curved path (as referred to above and describedv hereinafter) required in the squeezing zone (see Figure 4).
  • This squeezing. zone extends from the adjacent end of the rectilinear horizontal path of, the upper chain A to. a: point where the upper surface of the mat E of material for treatment comesunder pressure applying contact with the upper metal band F and the angle subtended by. this zone will vary with the thickness. of the, mat fed in. As shown in Figure 4, the squeezing zone extends from point X to point Z.
  • the width of the small gap is also governed by the permissible width when the band is lying (as a beam) across such gap in the rectilinear path. If the gap is too wide under pressure there would be a concave deflection of the band into the gap which would cause a discernible convex mark on the material. Therefore, in choosing the gap it must be limited to one which would not permit a concave deflection of more than, say, of the order of a few thousandths of an inch. Naturally the width of the permissible gap will vary according to the thickness and resistanceto deflection of the metal band.
  • Each gap may be a throughway gap with radiussed outer edges as shown at 33 in Figures 4 and 5, or by providing a sufiicient radius the required gap efiect may beattained without its penetrating throughout the thickness of the platen plates.
  • the idle lap of the upper chain A is supported on light rails 36 positioned below said lap and on to which the rollers of the links run as the upper chain links emerge from one chain wheel assembly and pass towards the other chain wheel assembly.
  • a pair of retaining pins 31 are provided across the open end of each bearing 26 and are accommodated in holes 38 provided therein (see Figures 4 and 5).
  • the upper chain A is mounted and proportioned such that its lower lap sags from its'chain wheel assemblies I5 and this sagging'portion at the feed end of the machine is constrained to travel through the squeezing zone X-Z in a path of predetermined curvature.
  • This curved path is preferably provided by extending the forward horizontal portion 39 of the said upper (abutment) rails I3 into a smooth curve of large radius (or radii) and this curved part may continue toward the vertical axial plane of the adjacent chain wheel assembly.
  • the path of the platens I9 of the upper chain A with their rollers I 4 running on the curved rail portion 39 guides the upper metal band F through the squeezing zone X-Z, in such a manner that transverse lines of unequal pressure are avoided and the band is not subjected to stresses which would impart a permanent set.
  • This effeet is brought about by co-ordinating the radius of the curved squeezing path with the gaps provided between platens having regard to the thickness or gauge of the metal band, the characteristic to bending of the metal and the pressure to be sustained. For example, with a tempered carbon steel band of thickness of .024 inch employed in a machine developing a pressure of the order of 300 lbs. per sq.
  • the curved squeezing zone path for platen 12 inches in width should have a radius not less than approximately 6 feet and the small gaps (taken in the straight run of the platens) should be about /8 of an inch across the adjacent end edges of the platens and about inch including the radiussed edges of the faces of the platens, opening to a maximum in the squeezing zone of about of an inch.
  • Both the upper and lower metal bands may be the same but it will be appreciated that as the lower band is operating under difi'erent conditions it may be of different metal and gauge, for instance it may be of stainless steel and of any suitable gauge.
  • Both metal bands are supported on rotary guide drums (as shown in the case of the upper band F on drums 40) appropriately positioned to lead the band between the upper and lower platens, the lower band being laid upon the lower platens as they assume their rectilinear horizontal run. It is convenient to arrange for the lower band D to be extended on the feed side to a mat laying or spreading station including a preheating zone where the material is treated to radio frequency heating currents. Also the lower band D may extend beyond the output end of the machine to deliver the formed board for further processing, cutting up and distribution. Thus as in the machine illustrated the guide drums for the lower band D are not shown. i
  • the upper band F is'led under the sag of the platens of the upper chain A to contact therewith in front of the maximum squeezin zone angle of the machine (see point Y in Figure 4).
  • the traction efiect of the chains upon the respective bands is suflicient to traverse the band along the bed at the same rate as that of the chains without independent driving means.
  • the hydraulic cylinders II for bringin the operating pressure to bear upon the material through bed rails I3, platens I9 and metal band F, are hydraulically coupled together into a system and to a suitable source of hydraulic pressure in such a manner that the pressure effected by the hydraulic pistons is uniformly distributed throughout the pressure beds.
  • Adjustable limit or stop means are provided for the hydraulic displacement accurately to determine the gauge to which the material is reduced under the applied pressure.
  • the hydraulic system and the adjustable limit or stop means used in conjunction therewith are not illustrated and may be of any convenient known character, the design of which forms no part of the present invention, the essential being that a positive stop is provided to limit the downward movement of the pressure beds so that the board is accurately gauged to the predetermined thickness required.
  • any suitable means for maintaining a heat treatment of the material concurrently with the pressure treatment between the pressure beds may be provided.
  • the platens or chain links may be electrically heated by resistance elements located or enclosed in the platens.
  • the heating may be done by radiant heaters situated close to the platen faces on the return laps.
  • the return laps of the metal bands may be supported in spaced relation to the return laps of the platen chains so that suitable heaters may be located in proximity to the platen faces on their return laps, to provide the necessary heating.
  • suitable heaters may be located in proximity to the platen faces on their return laps, to provide the necessary heating.
  • the parallel horizontal run of the platen chains maintains the pressure during the major or that part of the curing period of the thermo-setting binder component of the mixture where there is any substantial tendency to recovery or reactive swelling of the material.
  • the pressure bed I3 should extend for ten feet or such other length as required according to the curing period of the material and its properties of recovery and the rate of travel of the platens.
