All rims have a rims strip of some type, this is to protect the innertube from the edges of the spoke holes; which are often sharp & can swarf in them, not the spokes. If your spokes are protruding to hit the rim tape, sounds like the spokes are too long. also, in normal use, the spokes will not move or have any 'irregularities', these will stay in the same place.
