Clinging phase
Pressure is guaranteed by the vacuum generated by the machine, which allows the atmospheric pressure to exert its force on the flexible element, which in turn transfers it to the parts to be assembled.
-
Heating phase
Only the sealing edge is heated to a high temperature, while the rest of the garment is not heated. This solution prevents damage to any pre-existing seals or to any nearby element in the garment that might be subjected to unnecessary heating.
-
Cooling phase
After sealing, cool air is blown onto the sealed edges while the garment is still clinging through pressure so that glue can polymerize with no spring-back of the fibres. The result is a perfect seal capable of withstanding strong tensile stresses and remaining stable in time.
