I think that it means stamp something in production line. Once I've read "churn out a book" as a sardonic expresion.

Yes, you've got the sense of 'churn out' OK, but Anglika was right about the original use (without the "out"). There was nothing sardonic about the "uniforms" quote, and churn was used there as an intransitive verb. (We know the factories produced uniforms, but not from the grammar of the sentence.)
