Frequently Asked Questions (FAQ)

Q1 - What are the power requirements for semi-automatic pallet wrappers?

The power supply rating of almost all semi-automatic pallet wrapping machines is 110 / 120 VAC, 15 AMPS, 60 Hz.  The power plug used is the same standard 120 VAC plug / receptacle found in your home and office.

The use of a standard plug is especially useful for turntable style wrappers which are portable.  This allows the machine to be plugged in wherever it is convenient for your wrapping process in your warehouse or shop floor. 

Please consider that that for a brief moment, at the start of a wrap cycle, the machine could actually pull close to the 15 AMPS it is rated for.

This means that consideration should be given to NOT SHARING the machine on a 15 AMP circuit that already has high current demand running on it (eg. air conditioner, space heater, etc.).

For truly trouble free operation, the factory recommends dedicating a 20 AMP circuit to this machine, but obviously, your needs will dictate what is possible.

We also recommend avoiding the use of a long extension cord because the line voltage loss at 110/120 VAC over an extended distance can be significant and result in issues.

Q2 - What film (plastic wrap / stretch film) is needed for a wrapper with a pre-stretch film carriage?

All pallet wrapping machines with pre-stretch run industry standard machine film; typically "Machine film, 20" Roll width, 10" Diameter".

An ever diminishing number of machines use 30" Roll width film.
There are only two (2) industry standard sizes for film, 20" and 30".

The thickness of the film is typically expressed as 'Gauge' (Ga), with thinner film being lower numbers, eg. 40 Ga is thinner than 90 Ga.

Typically, a 50 or 60 Ga film is used when load retention is less important and you want more of a dust cover than a secure wrap.

80 to 90 Ga is typically used when the loads are heavier and load retention is more important.

If you need both light and heavy application of film for different load types, you can use a lighter film, and simply increase the number of wraps on loads that require better retention.  It takes longer to wrap the heavy loads, but saves you from having to change your film roll each time you have different load types.

Most pre-stretch carriages are factory set to a pre-stretch level somewhere from 200% to 250%.  200% is a very practical level that will successfully run just about any machine film you care to use.  Increased pre-stretch levels will improve film economy, but might require specialized films designed to accommodate higher pre-stretch levels (up to 300%).

In all cases, you should work with your film supplier, through a trial and error process, to find a film that best suits your needs.

Q3 - What do I need to consider when receiving a machine?

  1.  Most wrappers are forklift portable from one end.  (Some from both ends.)  This facilitates shipping of the machine and easy movement of the machine throughout your facility as your needs dictate.  A 3,000 lbs capacity fork truck, with 4 wheels, is recommended.
  2.  Please check the size of the shipping / receiving door, and any other doorways the machine must pass through to its final destination to ensure they are large enough to accommodate.  The shipping dimensions of the machines vary.  Please check your documentation or speak to your representative for details.
  3.  For turntable style wrappers it is important to ensure the machine is placed on a flat and seamless (crack-less) section of flooring to ensure even distribution of load weight and to help prevent structural issues.
  4.  For low profile turntable wrappers with a ramp, the ramp ships with the machine, usually stacked on the turntable, and must be manually installed.  Dependent upon the machine model, and your installation needs, the drilling and tapping of bolt holes may be required.  Unless otherwise arranged, the customer is responsible for this installation.

Q4 - How do I attach the ramp to my Mach 1 low profile pallet wrapper?

  1.  The "Ramp" typically ships on top of the wrapper turntable.
  2.  A "Ramp mounting bracket" is also supplied.
  3.  There are four (4) threaded holes in the pedestal base of the turntable support column.  There are two (2) "Set screws" shipped in 2 of these 4 holes.  Remove these "Set screws".
  4.  Attach the "Ramp mounting bracket" to the pedestal base of turntable first (using the "Set screws"), in the position appropriate for your needs.  (The holes are drilled to accommodate the standard three (3) ramp positions used by most applications.)
  5.  Then, position the "Ramp" close to the turntable, leaving approximately a 1/4" to 3/8" gap between the turntable plate and the ramp.  (Use a screwdriver or crowbar to maneuver the ramp.)  Attach the "Ramp" to the "Ramp mounting bracket" with bolts, fixing it in place, and maintaining a proper gap.
  6. Test the turntable rotation and ensure there is no binding.  Adjust if necessary.

The loading ramp must be attached to the wrapper’s base or anchored into the floor in such a manner that it will not be in contact with the rotating turntable.  A 3/8” gap between the two is advisable.  Furthermore, the ramp must be leveled at least 1/8” below the turntable’s surface to prevent rotating pallets from rubbing on it.

Recommended Tools:  Socket wrench; 9/16" Socket (long); Extension; Large flat head screw driver (or small crowbar)

Q5 - HOW-TO INSTRUCTIONS:
What should my pallet / skid / stretch / shrink wrapper settings be to properly secure my loads for shipment and reduce my stretch film costs?

Goals:

  • To properly secure the load for transport (keep loads from falling apart in the truck)
  • To provide protection against dirt and moisture (helps to keep products clean and dry)
  • To provide theft deterrence (make it harder for people to steal products)
  • To minimize packaging costs (save money on the cost of film by preventing needless over wrapping of your loads)

 

Quick Steps:

  1. Start a wrap cycle.
  2. Adjust the turntable speed to approximately 2/3 to 7/8 of maximum speed.
  3. Adjust the film force to the desired tension.
  4. Adjust the film carriage up (raise) speed of the film carriage until there is a film overlap of approximately 4" (100 mm).
  5. Adjust the overwrap height to make the film fold over the top of the load and create a band around the top of the load that is approximately 4" (100 mm) wide.
  6. Set the top wraps count to at least two (2) revolutions.
  7. Adjust the film carriage down (lower) speed to a fast rate.
  8. Set the bottom wraps count to at least two (2) revolutions.
  9. Repeat wrapping loads as necessary until satisfied with all settings.
