  Given an entire transcendental function f with a non-completely invariant
Baker domain, we define a Baker lamination on geodesics to study the divergence
and convergence of a pinching process of curves in U. If the boundary of some
curve in the Baker lamination of f contains infinity, then the pinching
deformation does not converge. On the other hand, if f is semihyperbolic, its
Julia set J(f) is thin at infinity, and the lamination does not contain
infinity, then the pinching deformation converges uniformly to an entire
function F. With this theorem, we prove the existence of an entire function
with a wandering domain W to a positive euclidean distance of its postsingular
set P(F).
