Stretch Wrapping Machine with Top Press Fixture

Executive summary Light, loose items such as rolls can shift or tip when a turntable starts turning and the film begins to pull on them. Our stretch wrapper solves this with a top press: a yellow arm lowers a plate onto the load and holds it down while the turntable turns and the film goes on. Film use follows from the load perimeter and its height. Both are set per project to your products.

What the video shows

An operator sets a group of six white rolls on the green turntable of our wrapper and draws clear film across them. The yellow arm overhead lowers its press onto the top of the rolls and holds them.

The turntable then turns, and the film carriage runs down the mast so the film builds up round the rolls. Near the end the operator steps back in to tidy the film tail. The rolls stay upright and grouped from start to finish.

How the top press wrapper works

Step What happens
Load Items are grouped in the middle of the turntable
Film start The film end is drawn across and held on the load
Press down The top press lowers onto the load and holds it
Wrap The turntable turns and the carriage travels the mast
Finish The film is cut, the press lifts and the load is taken off

The press stops the load lifting or shifting as the film tension builds. It also keeps the top layer flat, so the film wraps tight round the top edge.

Planning film per load

Illustrative example for six rolls in a 3 × 2 group, each 120 mm across and 250 mm tall, with 250 mm film at half overlap:

Item Value
Group footprint, 3 × 120 by 2 × 120 360 × 240 mm
Group perimeter, 2 × (360 + 240) 1,200 mm
Advance per turn at half overlap 125 mm
Spiral turns, 250 ÷ 125 2
End turns, 2 at top and 2 at bottom 4
Film laid, 6 × 1.2 m about 7.2 m

Short loads are covered mainly by the end turns. Set them in the program to suit.

When a top press helps

Load Why the press helps
Light rolls and cartons They cannot lift or slide
Tall, narrow stacks They do not tip as the table starts
Soft goods The press keeps the top flat
Mixed groups Items stay grouped as one pack

Heavy, stable pallet loads usually do not need a press.

Controls and safety

The top press comes down onto the load and the turntable turns. Keep hands off the load top while the press lowers, and clear of the turntable while it turns.

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.

Selection checklist for a top press stretch wrapper

  • Load size and weight range.
  • Loads per hour.
  • Light, tall or loose items.
  • Turns and overlap wanted.
  • Pallet or no pallet.
  • Floor space and power supply.

Engineering FAQ

Q: What does the top press do? A: It holds the load down on the turntable, so light or loose items cannot lift, shift or tip.

Q: What loads need a top press? A: Light rolls, cartons, tall narrow stacks and soft goods.

Q: How much film per load? A: Turns times perimeter. Our six-roll example lays about 7.2 m.

Q: Does it need a pallet? A: No. The rolls in our video stand straight on the turntable.

Q: Do heavy pallets need a press? A: Usually not. Heavy, stable loads stay put under film tension.

Next step
