Claim:
Arrangement for making a belt made of plasticatable material, the arrangement comprising: a first station for making a first belt part; said first station including a first extruder and a first mold drum; a continuous mold belt assembly including an upper pressure roller, a lower pressure roller, a tensioning roller and a continuous mold belt; said upper pressure roller, said lower pressure roller and said tensioning roller being mounted relative to said first mold drum so as to guide said continuous mold belt over an arcuate portion of the peripheral surface of said first mold drum so as to permit said continuous mold belt and said first mold drum to conjointly define a hollow mold space over said arcuate portion of said peripheral surface; a filament feed for feeding filaments into said hollow mold space; said first station further including a first extruder for outputting the plasticatable material onto said first mold drum whereby said first belt part is formed with said filaments between said mold drum and said mold belt; a second station for making a second belt part and for forming said second belt part onto said first belt part; said second station including a second mold drum and a direction-changing roller for guiding said first belt part incorporating said filaments to said second mold drum; a second extruder for outputting plasticatable material onto said first belt part thereby forming said second belt part which is joined to said first belt part on said second mold drum to form said belt; said direction-changing roller and said second mold drum conjointly defining a spacing therebetween which corresponds to the thickness of said belt; and, said second station further including means for applying a force to said belt as said belt leaves said second mold drum so as to cause said first belt part with said filaments to function as a mold belt with respect to said second belt part.
