Zero Glue is a set of solutions for the material bonding with ultrasonic technology.
The most important benefits in eliminating the use of adhesives during the product assembly are the lower risk of glue contamination, the production costs reduction and the improvement of the quality and process performances.
In order to remove the glue from the tape application process, while maintaining the necessary mechanical characteristics between tape and the rear wing sub-layer, a new type of ultrasonic welding unit, linked with a specific Slip and Cut applicator, has been developed to splice the tapes on the rear wings.
The USB unit is equipped with a control panel that allows setting the main process parameters in order to have the desired welding with different raw materials. Gap between horn and anvil, thus welding force, is controlled by a step motor.
By Ultra Sonic Bonding technology, the Acquisition Layer is fixed and embossed onto the topsheet nonwoven through a heating process; different welding patterns can be used according to the product specification.
In order to remove the glue from the topsheet assembly process, while maintaining the necessary mechanical characteristics between standing gathers nonwoven (cuff) and central nonwoven, a new type of ultrasonic welding unit has been developed to perform the topsheet nonwoven web assembly.
The USB unit is equipped with a control panel that allows setting the main process parameters in order to have the desired welding with different raw materials. Gap between horn and anvil, thus welding force, is controlled by a step motor.
The new kit for cuff elastic entrapment by USB exploits rotary ultrasonic bonding technology to secure elastic strands into nonwoven structures, preventing leakages and improving diapers softness.
The ultrasonic bonding system directly entraps tensioned elastic within a thermoplastic substrate enabling high speed performances.
