STRETCH WRAPPING

Stretch Wrapper

After unitizing your loads on pallets / slip-sheets, the next big challenge is to find a way to keep them together as one. Pallet loads of products could be stabilized and protected better if wrapped in layers of stretched plastic. The elasticity of the film would act much like a rubber band, tightly containing the products.

This innovation of keeping unitized loads together came about 30 over years ago and has been perfected over and over again for the past 3 decades. We are proud to represent the founder of this innovation and the market leader in this technology, LANTECH.

Uptime
MACHINE CONSTRUCTION
NEW DESIGN
 
OLD DESIGN
  • Boxed top and bottom for support and strength.
  • Stuctural steel tubing.
  • Steel cross member reinforcements.
  • ABS panels allow easy service access and will not rust or dent.
  • Exposed components susceptible to damage and can cause operator injury.
  • Maintenance access is difficult.
COST OF MAINTENANCE
NEW DESIGN
 
OLD DESIGN
  1. 48" diameter uerthane race provides broad balanced support.
  2. Sealed-for-life bearings.
  • No maintenance, no lubrication.
  • Dependable belt drive.
  • No metal-to-metal wear.
  • Washdown capability.
  1. Metal-to-metal contact of cam followers to steel turntable cause noise and high wear.
  2. Chain and sprocket systems require proper lubrication and adjustment. Chain will sag and cause uneven wear of sprocket.
SUPPORT SYSTEM
NEW DESIGN
 
OLD DESIGN
  • 38" precision ring bearing for high speed / heavy duty applications (6000 lb loads).
  • 38" slew bearing.
  • Typically 20"-25" ring gear bearing.
  • Smaller diameter bearing does not distribute weight of load effectively.
  • 33" bearing on some high speed models.
Performance
SIMPLE AUTOMATION FEATURES
NEW DESIGN
 
OLD DESIGN
  • Automated Film Cut and Clamp Unit on Q-300 XT and Auto Film Cut-off™ on Q-300.
  • Remote START lanyard switch keeps driver on fortruck (Q-300 XT).
  • Improve productivity and plant flow.
  • Forktruck driver gets off/on forktruck to cut and tuck film, and start the wrapping cycle.
  • Inefficient use of forktruck and labor resources.
FILM DELIVERY PERFORMANCE
NEW DESIGN
 
OLD DESIGN
(1) No gaps.
(2) 180 degree wrap-to-roller contact.

Two Critical Factors:
• 180 degree film-to-roller contact during stretch process.
• Floating nip roller maintains 180 degree contact of film-to-rollers and prevents film slippage.
Result:
• Minmal neckdown of film web.
• Maximizes film stretch percentage.
• Eliminates film slippage across the stretch rollers.
• Neutralizes film breaks.
• Provides lowest film usage per load.


 
(1) Large unsupported gaps.
(2) Insufficient wrap-to-roller contact.
(3) Film neckdown.

Inconsistent Control of Film Stretching:
• Film contact to rollers is less than 180 degrees.
• Nip roller not used to eliminate gaps between rollers.
• Fixed nip roller does not engage pre-stretch roller for optimal film control.
Result:
• Film slips across rollers reducing potential stretch level.
• 3" - 5" of neckdown is common.
• Uneven unitization of load from top to bottom.
• Film breaks are common.
• Cumulative result is higher packaging cost.

AUTOMATED LOAD-SEEKING FILM CLAMP
NEW DESIGN
 
OLD DESIGN

Lantech film clamps are designed to be overwrapped with film for optimum unitization at lowest cost.


• Captures film tail.
• Maximizes load containment.
• No film residue in clamp.
• Load arrives "as shipped".

Rigid scissors and jaw-style film clamps are seldom overwrapped with film, which produces high cost unitization.


• Film tails are loose and trailing.
• Load containment is uneven top to bottom.
• Loads will shift during transit causing product damage.

FILM CUTTING SYSTEM
NEW DESIGN
 
OLD DESIGN
(1) Guarded hot wire never contacts film.
(2) Film.

• No film build-up on hot wire.
• Wire temperature adjustable for film gauge and work area.


(1) Hot wire contacts film to cut, causing residue build-up.

• Unguarded hot wire is a burn hazard to operator and product.
• Film build-up on hot wire causes inconsistent film cling.

LOAD CONTAINMENT
NEW DESIGN
 
OLD DESIGN
5 up and 5 down turntable revolutions provide optimal two-way wrap pattern because clamps can be wrapped for full sequence.

5 x 5 Biaxial Wrap
• Film overlaps clamp at start and finish of wrap cycle.
• Leading film tail secured in clamp during full wrap cycle.
• Leading film tail secured to load underneath bottom film wraps.

2 up and 8 down turntable revolutions primarily provides one-way wrap pattern because film clamps cannot be wrapped for full sequence.

2 x 8 Wrap
• Film cannot overlap clamps because clamps cannot release from film.
• Film is released from clamp early in wrap cycle and high on the load so roll carriage can clear clamps.
• Film tail is released mid-air and not captured.

Ease of Use
FILM THREADING
NEW DESIGN
 
OLD DESIGN
  • E-Z Thread™ roll carriage loads film correctly every time.
  • Side mounted roll carriage is easy to load and reduces risk of back and hand injury.
  • Top latching gate is difficult to close and may malfunction.
  • Welded bottom hinges can warp and break.
  • Film payout opposite operator side.
OPERATOR FRIENDLY
NEW DESIGN
 
OLD DESIGN
  1. Easy to read controls precisely control key unitization factors.
  2. Quick Reference Guide on machine includes Operating Instructions and Trouble Shooting Guide.

  • Basic control package does not provide optimum load containment control.

FILM LOADING
NEW DESIGN
 
NEW DESIGN
  • Q-1000 floor space available to operator to load film.
  • Operator stands on floor.
  • Roll carriage mounted on side of upright.
  • Roll carriage mounted on front of upright.
  • Operator stands on turntable to load film.
  • Operator will lift 40 lb film roll above waist while standing on turntable.
SIMPLIFIED MAINTENANCE
NEW DESIGN
 
OLD DESIGN
  • Only visual maintenance is needed.
  • Easy to access all serviceable components.
  • Lube lines for hard to reach elements.
  • Periodic maintenance of ring bearing.
  • Belt lift roll carriage.
  • Belt driven wrap arm.
  • Panels remove from mast for easy access.
  1. Limited access to required service areas. Chain driven roll carriage and wrap arm must be continuously adjusted and lubricated.
  2. Chain will sag and cause uneven wear of sprocket.
OPERATOR FRIENDLY WITH PHOTOEYE
NEW DESIGN
 
OLD DESIGN
  • Intelli-sensor™ photoeye sees all types of loads.
  • Effortless overwrap adjustment.
  • Mechanical load height sensing.
  • Requires adjustment for varying load heights.
Safety

  • Side mounted carriage.
  • No pinch points.
  • 65" turntable standard
  • Trip hazards - base protrusions.
  • Front mounted carriage.
  • Pinch points.
  • Loads overhang turntable.
ROLL CARRIAGE GUARDING
NEW DESIGN
 
OLD DESIGN
  • Powered rollers are fully shielded from hands and clothing for safest operation.
  • Pre-stretch rollers "powered" during wrap cycle only.
  • Open" roll carriage design allows hands and clothing to snag in rollers.
  • Pre-stretch rollers "powered" at all times.
ROLL CARRIAGE DRIVE SYSTEM
NEW DESIGN
 
OLD DESIGN
(1) Counterweight
(2) Roll Carriage

• Counter-weighted roll carriage reduces cumulative downward force to less than half the weight of roll carriage.


(1) Roll Carriage
(2) Chain Drive

• Chain driven roll carriage exerts downward force equal to weight of roll carriage plus downward force of chain drive.

OPERATOR PROTECTION
NEW DESIGN
 
OLD DESIGN
  1. Fencing with
  2. interlock safety gate. Not an option.
  3. Transition jam and wrap zone photoeyes.
  4. Flow Direction.
    • Personnel barrier. Not an option.
  • Safety fencing is an option.
  • Stockade-style fencing allows easy access.
  • Gates not always safely interlocked.
