ABSTRACT:
A package wrapper shaping apparatus which has lateral folders and folding slides for wrapping a blank around a shaping mandrel. In order to guide the free portions of the blank in a defined manner in this process and to put their outer edge portions on one side of the shaping mandrel in contact with one another, the lateral folders and the folding slides are embodied in comb-like fashion with teeth, so that they mesh alternately with one another in pairs as they fold over the end portions of the blank.
