An apparatus for manufacturing a strip of rubber compounds comprises four extruders ( 2 a , 2 b , 2 c , 2 d) and a single extruder head ( 3 ). The extruder head ( 3 ) comprises an extruder die assembly ( 6 ) and a main body ( 4 ). The main body ( 4 ) is composed of a pair of laterally-spaced lateral blocks ( 11 ), a central block ( 10 ) disposed between the lateral blocks, and a pair of laterally-spaced sub blocks ( 13 ) disposed beneath the lateral blocks ( 11 ). The central block ( 10 ) has a pair of V-form side faces ( 15 ) extending in a V-shaped formation down to lateral ends of the bottom face (S 1 ). The lateral blocks ( 11 ) are each provided with an upper mount face ( 21 U) and a lower mount face ( 21 L) on which two of the four extruders are respectively attached. An upper preforming channel ( 24 Ua, 24 Ub) extending from an extruder to the die assembly has a parting plane along the V-form side face ( 15 ). A lower preforming channel ( 24 Lc, 24 Ld) extending from an extruder to the die assembly also has a parting plane.
