FORMING DEVICE FOR FORMING A SINGLE FIN TUBE

摘要

An apparatus for forming a single-fin wrapper sleeve about articles advanced through the apparatus, comprises a conveyor for advancing the articles in a conveying direction and in a plane of conveyance and a shaping body having a vertical longitudinal halving plane extending parallel to the conveying direction and perpendicularly to the plane of conveyance. The shaping body includes a first main forming surface including a planar surface portion and a second main forming surface joining the first main forming surface downstream as viewed in the conveying direction. The second main forming surface has a gradually closing tubular shape surrounding the conveyor and a longitudinal slot extending underneath the plane of conveyance parallel to the conveying direction and symmetrically with respect to the halving plane.
