• Labels and emblems
Shrinkage, finishes and coatings on the textile can influence the heat sealing result in a
negative way.
Pre-heating can offer a solution in some cases.
If it appears that there is not a complete adhesion, it is recommended to re-seal another 10
seconds.
Remark:
Some modern fabrics cannot withstand the heat sealing temperature of 204 °C. If you
cannot be sure of the result, use a sample of the same fabric, if possible, to establish
its heat resistance. Also care labels in garments can inform you of their heat resistant
properties (iron ability). When it is necessary to lower the temperature, it is necessary to
press for a longer time.
How to remove heat sealed Thermopatch labels:
Because Thermopatch labels must be wash resistant to all industrial washing processes, it
is not easy to remove heat seal products.
When necessary you can try following procedure:
• Put the garments with the label to be removed under the press for about 7 seconds. The
glue layer will melt again.
• Leave the garment on the plate and remove the label, if necessary by means of a blunt
scraper or tweezers.
• Please note: Heating plate and labels are hot!!
• Repeat this procedure if you are not successful the first time trying.
Interrupting the heat sealing cycle:
You can interrupt the operation at any moment by unlocking the arm of the closed heat seal
machine during the press cycle.
When you wish to shut down the machine, switch the main switch to off. It is located on the
right side of the machine.
The indicators on the control panel are then turned off.
Trouble shooting:
Some problems and failures that can occur, are listed below.
After describing each problem, the possible cause (sometimes more than one) is given, as
well as a possible solution.
If the described solution cannot solve the problem, please contact the service department
of your distributor.
Heat sealing problems:
Insufficient adhesion of the glue layer
• Press time too short.
• Increase the time in steps of 2 seconds and try again.
• Temperature too low.
• Check with Thermolabels and increase the temperature, if necessary.
The pressure is not sufficient.
• The silicone rubber sealing pads are worn out: replace when worn.
• The sealing pressure is set in the factory and cannot be adjusted.
• The teflon self-adhesive coating of the press element is dirty or worn-out.
• Clean with a damp cloth and replace it, if necessary. When replacing the old teflon, it is
very important that adhesive residue is removed from the heating element. To do this it
is necessary to heat up the machine, scrape off the glue remains by using a blunt edged
scraper. It is important to avoid scratching the metal of the heating plate.
• After this is done, degrease the heating element and apply the self-adhesive teflon
cover.
Glue layer becomes too thin, causing adhesion problems
• Sealing time too long.
• Lower the time in steps of 2 seconds and try again.
• Temperature too high.
Check with Thermolabels and lower the temperature, if required.
