The hood applicator head prepares the gusseted film tube for the stretch hood
formation. The subassemblies for the individual working sequences are inte-
grated into the frame of the hood applicator head.
The film tensioners stretch the gusseted film tube. For this, the four side fold
clamps take the gusseted film tube at its edges, and the film tensioners move
apart. The film grippers of the four gripper arms grip the gusseted film tube. The
gripper arms swivel downwards, thus opening the gusseted film tube. The side
fold guiding plates help to open the gussets. The side fold pins hold the gussets
while the gusseted film tube is stretched and sealed.
The two sealing rails and the knife are mounted on the sealing bar. The sealing
rails seal the open gusseted film tube into a film hood closed at the top. Then the
knife cuts the film hood off the gusseted film tube.
After the film has been cut, the film retriever pulls the gusseted film tube back
into a defined position. The film brake prevents the cut gusseted film tube from
