図8に示す混練部13のセグメントパターン20Eでは、ショートセグメントパーツ22とロングセグメントパーツ23とが混在して用いられている。具体的には、第1のセグメントパーツ21Aを3/2倍(すなわち、n=3、S=2であり、1.5倍)の長さとした第1のロングセグメントパーツ23Aと、第2のセグメントパーツ21Bを3/2倍の長さとした第2のロングセグメントパーツ23Bとが、第3のショートセグメントパーツ22Cに加えて用いられている。セグメントパターン20Eでは、混練材料の搬送方向Pに向かって順に、第3のショートセグメントパーツ22C、第1のロングセグメントパーツ23A、第2のロングセグメントパーツ23Bが連結して組み合わされている。
図9に示す混練部13のセグメントパターン20Fでは、セグメントパーツとして混練材料の混練を主目的とするニーディングブロックがスクリューエレメントと組み合わせて用いられている。
また、図10に示すセグメントパターン20Gのように、長さL2を有するニーディングブロックである第2のセグメントパーツ24Bを組み合わせて用いるようにしてもよい。
