Description

Uppfinnare: R Andersen De band, som anvandas for transport av tunga massor, exempelvis sten ■och malmer i fabriker, behova aga stor dragstyrka, varfar de armeras med ett eller flera gummi-impregnerade vavda textillager. Vidare maste Oven Oversidan, som kall upptaga massan, vara forsedd med en mer eller mindre elastisk tackplatta for upptagande av pakanningarna vid massans nedfallande pa bandet, vilken platta dock maste vara hard for att icke upprivas f8r snabbt av nedfallande skarpa stenar eller liknande. Som tackplatta anvandes vanligtvis kompakt gummi eller andra lampliga material. Mellan taekplattan och armeringslagret ar vidare ingjutet ett mjukare elastiskt lager avenledes av kompakt gummi, sa att tackplattan kan fjadra vid belastning. leke desto mindre visar det sig, att thekplattan kan rivas upp av ovannamnda skarpa material sarskilt, nar materialet vid fallet traf far bandet pa stallen, dar det är understott exempelvis av barrullar, beroende pa att namnda elastiska lager joke .formar fordela trycket pa en storre yta under tdckplattan mot armeringslagret. Inventor: R Andersen The belts used for transporting heavy masses, such as stone and ores in factories, need to have a high tensile strength, whereupon they are reinforced with one or more rubber-impregnated woven textile layers. Furthermore, the upper surface, which coldly absorbs the mass, must be provided with a more or less elastic roof plate for receiving the packings when the mass falls on the belt, which plate, however, must be hard so as not to be torn too quickly by falling sharp stones or the like. Compact rubber or other suitable materials were usually used as the roofing plate. Between the roof plate and the reinforcement layer, a softer elastic layer is further cast, made of compact rubber, so that the roof plate can spring under load. play it nevertheless turns out that the teak plate can be torn up by the above-mentioned sharp materials especially when the material in the case hit the belt in the stable, where it is supported for example by bar rolls, due to the said elastic layer joke .forms to distribute the pressure on a larger surface under the cover plate against the reinforcement layer.

Denna oligenhet loses enligt uppfinningen pd det sattet, att det mjukare lagret utgores av ett poroselastiskt lager sasom elastisk cellplast, cellgummi eller liknande. Ddrigenom uppnas, att den forhallandevis harda tackplattan kan fjadrande giva efter pa ett hell annat satt for tunga, skarpa delar av massan an vad som ticligare varit fallet, varigenonn risken for upprivning i thekplattan minskas vasentlig grad och bandets livslangd blir i motsvarande grad langre. Eft genom en punktartad tryokbelastning pa tackplattan astadkommet tuck pa armeringslagret kommer harvid att fordelas ph en mycket stor yta. This inequality is solved according to the invention in the sense that the softer layer is constituted by a poroselastic layer such as elastic cellular plastic, cellular rubber or the like. This ensures that the relatively hard roofing plate can resiliently yield to heavy, sharp parts of the mass in a completely different way than has previously been the case, whereby the risk of tearing in the roofing plate is significantly reduced and the life of the belt is correspondingly longer. Due to a point-like pressure load on the roofing plate produced tuck on the reinforcement layer will then be distributed over a very large area.

Aven pa den ena eller bada sidokanterna kan bandet f8rses innanfor kanten av kompakt gummi med ett dylikt mjukt lager av cellplast eller cellgummi. Even on one or both side edges, the strip can be moved inside the edge of compact rubber with such a soft layer of cellular plastic or cellular rubber.

Bifogade ritning visar en tvarsektion av en utforingsform av ett transportband enligt uppfinningen. The attached drawing shows a cross section of an embodiment of a conveyor belt according to the invention.

Tackplattan pa transportsidan av bandet är betecknad med 1, det armerade lagret med ingjutet, vavt textilmaterial med 2, tackplattan pa rullsidan med 3 och gummikanterna med 4. For lagren 1, 3 och 4 samt for gjutmaterialet for armeringen 2 kan, som namnts, kompakt gummi anvaadas. Med 5 betecknas det mjukare lagret mellan lagren 1 och 2. Detta lager 5, som bestir av eellplast, cellgummi eller liknande, kan vid bada andar fortsatta neat ett stycke, som visat vid 6, och pa sidan taekas av gummikanterna 4 av kompakt gummi. The roof plate on the transport side of the belt is denoted by 1, the reinforced layer with cast, woven textile material with 2, the roof plate on the roll side with 3 and the rubber edges with 4. For bearings 1, 3 and 4 and for the casting material for reinforcement 2 rubber anvaadas. 5 denotes the softer layer between layers 1 and 2. This layer 5, which consists of plastic, cellular rubber or the like, can in both spirits continue not a piece, as shown at 6, and on the side is taken by the rubber edges 4 of compact rubber.

Claims

Patent claim: Conveyor belt composed of roofing plates and intermediate reinforcing layers, wherein a softer elastic layer is molded between the roofing plate on the transport side and the reinforcing layers, characterized in that the softer layer (5) consists of a porous-elastic layer such as elastic foam, rubber or similar rubber .
