The trunks do get wider, but it's a different process than the typical secondary growth we see in dicots and gymnosperms (monocots also lack secondary growth; those with trunks, such as palms, have yet another process for widening the trunk).
For tree ferns, the "trunk" is basically a mass of roots that have been fused together. For the trunk to widen, new roots are formed and added to the mass.
