  The production of $f_{1}$ ($J^{PC} = 1^{++}$) mesons in proton-proton
collisions via pomeron-pomeron fusion is discussed. Two ways to construct the
pomeron-pomeron-$f_{1}$ coupling are presented. Comparisons with data from the
WA102 experiment are made and predictions for RHIC and LHC experiments are
given.
