How Can Fromm Help Get Your Strapping Tool Fixed?

At FROMM, we make strapping tools that are built to last. Most times, they are immune to the ravages of wear and tear.But, like most products, strapping equipment works best with regular care and maintenance to keep it working at peak performance. Apart from basic cleaning, other more complicated tasks are best left to the experts.

Tool Issues And Troubleshooting Techniques

While we do not recommend opening up strapping tools without prior knowledge, some problems can be easily rectified. Here are some basic strapping tool issues and how you can deal with them.

Strapping Tool Doesnt Work at All

If you find that the tool doesnt operate at all, there could be several different reasons. The battery could be drained, defective or not making proper contact in the case. Check to make sure the battery charges properly in the charger and the battery seats properly in the tool. Sometimes, simply removing the battery and reseating it in the case is enough to ensure proper contact points. If you have a spare battery, try it in the tool, sometimes batteries can appear in working order but are actually defective. If your tool still doesnt work, it could indicate a much more serious problem like a defective motor or circuit board. Fill in the tool repair request form and we can assist you with the issue.

Tensioning Strength is Inadequate

If a strapping tool does not have adequate tensioning, after adjusting the appropriate settings, it could be because the tensioning wheel is dirty or worn out. Often, an issue like this causes the strap to slip as the tension of the strap increases. Sometimes blowing air into the area is enough to remove the debris. If you have enough expertise, you could clean or replace the grippers as required. Care should be taken not to use any hard objects during this process. Sometimes, tensioning strength can also be due to a faulty microswitch or a circuit board. In these situations, the tool will need to be sent in for servicing.

Strapping Tool Does Not Weld

Many different components within the tool work together for a proper weld. If after adjusting the tool for welding time you still have problems, the tool may need to be serviced. Once again, try blowing the tool out with air. If that does not work some components such as grippers, springs or motors may need to be serviced. This is best left to a qualified service technician.

Tool Does Not Cut

The tools inability to cut the strap can mean wastage of time and material. Checking and adjusting the cutter can usually solve this problem. You could also try cleaning it, failing which,  it might be time to replace the cutter. It might also be a problem with the pressure spring, and it may need to be replaced.  Fill in the Tool repair request form and we can assist you in fixing these items.

Troubleshooting guide for automatic strapping machines

No doubt that you have already encountered the problem that your strapping machine seemingly broke down and needed service. This is very natural, but sometimes it turns out that the experienced malfunctioning is not a failure in reality, but the result of a bad setting or the choice of a non-compatible strip.

Calling a specialist is not a profitable step in this case.

UNIOTECH POCKET GUIDE will help you solve the most frequently encountered problems.

Almost all tips are applicable for all types of automatic (frame) strapping machines, so no specific type is mentioned.

1: The strapping machine pulls in and threads the strap with difficulty, extreme noise can be heard from the machine while strap feeding.

  • Check whether the running direction of the strap and the marking on the strap holder are the same. When the threading direction is not good, the break works inefficiently or it does not work at all or quite the contrary, it works continuously.
  • Check whether the strap is threaded into the roller of the brake lever.
  • (Only in case of machines with mechanical locking system) check whether the tensioning force is not too small. Some machines can have problems with feeding when the tensioning force is too small.
  • Check the quantity of strap in the strap container compartment. Too small strap quantity can cause inefficient threading, too many strap can result in strap folding.

2: The machine cockles the strap at withdrawal:

  • Dirt or a piece of strap in the mechanics. Try cleaning with compressed air. If unsuccessful, call our service.

3: At the end of tensioning, the machine does not strap, maybe extreme noise can be heard.

  • Check whether the tensioning sensor works appropriately.
  • At excessive tensioning power, the tension wheel can slip on the strap before reaching the set value, in this case the machine stops tensioning. Reduce the tensioning force.

4: The strip breaks lengthwise, splits in two or sometimes bends.

  • At excessive tensioning force, the damage of strap at strapping can happen. Reduce the tensioning force.

5: The strap breaks from time to time at its sealing:

  • Unsatisfactory temperature can cause improper sealing. Maybe the error is dependent of the drop of ambient temperature or the increased frequency of strapping. Increase the sealing temperature.

6: Smoke from the machine at the strapping head:

  • Exhausting ventilation works inefficiently. Clean the airway and ensure the free running. If the ventilation is not working, call our service regarded the replacement.

7: The tension is smaller on one of the boxes than on others:

  • Sometimes the variable box size can cause tension differences. Try the machine in way that you do not change the box size during a series of strapping. If the error persists, call our service.
  • Check whether the low limit for box sizes is not exceeded. In some machines this ranges between 120-150 mms. For packages smaller than this, the machine is unable to adjust strapping tension.

8: The straps comes out of the frame during threading:

  • Check strap sabre.
  • Maybe the strip is threaded inversely (related to its own curving, the strip should osculate to the wall of the frame, not moving away from it). Turn the strip 180° if needed.

9: When the package is heavy, after strapping the machine stops and throws out the strap:

  • In some machines the strapping plate is held by a rubber spacer. If this part vanishes, the plate bands over the frame, blocking the free running.

10: The machine performs a good strapping, but in continuous operation it stops and throws out the strip:

  • Not enough strip in the container, or too strong brake at the pulley. The machine uses up the strap from the container.

If problems other than listed above occur, (the machine is not working at all, the mechanics cannot move etc.) calling the service is recommended.

We hope that these tips are helpful for you.
