A pultrusion method for making a composite elevator belt includes pulling at least one load carrier strand coated with a core layer into a pultrusion die including a plurality of molding teeth and intervening spaces between the molding teeth having a profile shaped to form a desired profile of belt teeth on the core layer. The method further includes filling the intervening spaces between the molding teeth of the rotating die with resin, depositing the resin on the core layer, forming a plurality of the belt teeth on the core layer using the rotating die, pulling the core layer with formed belt teeth into a jacket extruder, and forming a jacket layer on the core layer with the formed belt teeth to complete the composite elevator belt.
