Bag tops are clamped against spreading horns by sensor equipped clamps which cause disablement of a bag filling mechanism unless a bag is properly located at the load station. The horns include mirror image subassemblies each including stationary and moveable sections. Each subassembly includes a prime mover interposed between the sections to relatively move the sections between collapsed and bag extending positions.
