Bonding

Thermal bonding
The Thermal bond unit consists of two heated rolls. Typically one roll is patterned and the other is smooth. Air cylinders may used to apply minimal pressure between the anvil and the pattern roll.

Ultrasonic Bonding
The Ultrasonic bond unit consists of an anvil roll and stationary (or rotary) ultrasonic assemblies.
The ultrasonic assembly bonds multiple layers of the product together by use of vibration and pressure.
The product web wraps the patterned anvil roll as it passes under the head of each ultrasonic unit.
Bonding takes place when the head and anvil compress the product web.

Hot Melt Adhesive Bonding
Hot-melt glue is loaded into a heated tank. The glue is melted and pumped to an applicator head. In many cases, the glue head is allowed to contact the web during the glue application. The glue applicator may include electronics to apply the glue in a preset pattern.

Mechanical Bonding
The Mechanical Bonding unit consists of two rolls. Typically one roll is patterned and the other is smooth. Air cylinders, or other methods, may used to apply the required bonding pressure between the anvil an the pattern roll.

Laser Bonding
A laser can be used to bond similar materials together. Typically this is done as a web is transferred along a deadplate or conveyor.

Each of these processes has inherent advantages and disadvantage. Please contact us for the preferred bonding method for your application.
