They would cross in the center. Maybe you can make it so that the filaments do not touch each other in all valid cariage positions. If you mind the small non-linearity that much then just make the drum/spool diameter smaller at the sides so that the ciscumference decrease is just as big as the error term (d-d*cos(α) ... or slightly different expression if the cerberus geometry is not just the same as I assumed).
