are illustrated in fig2 b and 2c preferably the elastomer of each cap should extend over about 30 percent of each opposing flat surface of the belt core 202 furthermore preferably up to about 70 percent of the belt 200 should have a lower modulus of elasticity to aid the hay baler in driving the belts the process of applying the outer cover 203 is preferably accomplished by crosshead extrusion wherein belt core 202 is passed through a crosshead that is capable of extruding at least two different elastomers in the same process it is important that the various elastomers be able to bond to all of the constituents of the belt core the belting of fig3 a and 3b combine the advantages of the wrapped belting of fig1 a and the advantages of the encapsulated belting of fig2 a first edge wraps 304 and 305 are applied to the belt core 302 as in the embodiment of fig1 a discussed above then caps 306 and 307 and outer skims 308 and 309 are applied to the belt core 302 and edge wraps 304 and 305 to form a complete encapsulation as described in the embodiment of fig2 a discussed above as discussed in reference to fig2 a the hardness of the elastomer of the caps 306 and 307 should be greater than the hardness of the elastomer of the outer skims 308 and 309 as an example of a preferred embodiment the belt core 302 comprises three fabric plies of woven nylon and polyester fibers the fabric plies are joined by an elastomer of thermoset synthetic rubber the edge wraps 304 and.
