Hot Melt Both Side Coating Machine

This machine is a hot melt adhesive coating machine. The machine has two heads of slot die coating and two melting units. This enables to coat on both sides of the substrate in a single operation. As a result, it gives double production and less wastage.

This machine is designed especially for making sticky insect traps. It has the capacity to hold 300mm wide rolls and coat up to 300mm wide. Along with double coating heads, it has 3 unwinds and 1 rewind.

Two unwinds hold rolls of the release liner. These liners are coated with slot dies. These slot dies are fed with molten glue by two independent melting units. Both melting units have gear pumps for the controlled, constant and measured flow of glue.

After coating on the release liners, both the papers are laminated with the PVC film sandwiched in between. This PVC film is dispensed from the third unwinder. After the lamination, all the three plies are wound at the winding station.

All the unwinders are equipped with magnetic powder brakes and web guiding systems. The rewind station has a magnetic clutch for a taper tension controlled winding.
