This three-roll transfer coater supports continuous and intermittent coating for surface coating on various substrates, widely adopted in the lithium-ion battery industry.

Key Features

Double servo lead-screw control for the metering roller adjusts the trailing edge for slurries of different viscosities.
Equipped with receiving platform, partition platform, unwinding tension control and dual tension trailing system.
Edge correction units installed at the unwinding section, oven outlet and trailing section.
Freely switchable between continuous and intermittent coating modes.
Substrate tension control ensures stable web transport with an edge correction unit.
Hot air oven with top and bottom dual air supply for superior drying performance.
Three-roll transfer coating with a wide processing window.
Comma doctor blade paired with a precision adjustment mechanism for high coating accuracy.
Analog power heating control delivers outstanding temperature precision and long service life.
PLC control with intuitive touchscreen operation.
Optional solvent recovery treatment unit.
