  We consider exactly solvable 1d multi-band fermionic Hamiltonians, which have
affine quantum group symmetry for all values of the deformation. The simplest
Hamiltonian is a multi-band t-J model with vanishing spin-spin interaction,
which is the affinization of an underlying XXZ model. We also find a multi-band
generalization of standard t-J model Hamiltonian.
