The machine is mainly used in lab for calendering finishing test of non-woven fabric, cotton fabric, wool fabric, chemical fiber fabric, hemp fabric, and  mixture fabric. The Lab Calender can also be used to make the touch-feeling sample

Before a mass production in a dyeing or finishing factory, in order to avoid waste due to the wrong production process, people usually do some tests in laboratory to get the verified correct process recipe as the basis for the workshop production. .

The Lab Calender uses advanced mechanical structure and precise, automated control systems to simulate the true operating conditions of mass production, the machine provides a reliable test result and true experiences of trial production for the research and mass production.

Structure of Machine

The machine consists of main frame, Calendering rollers, transmission parts, hydraulic system and electrical control components, etc. Calendering rollers are the key component of the machine, its structure is complex, calendering system consists of a hard heating roller and a Soft roller.

1. Hard calendering roller is a heating roller with mirror-surface, the internal structure is hollow, with electrical heating or oil heating. Electric heating rods power is 3KW, temperature can be set. The Roughness of roller surface is less than 0.2um after grinding and chrome finish.

2. Soft calendering roller consists of hollow steel roller and wrapped with Nylon

3. Transmission system consists of a frequency conversion motor, cycloid reducer, chain, gears, etc.

4. Hydraulic driven system consists of pump, pressure relief regulator, electric pressure gauge. etc

5. Temperature control system consists of temperature sensor installed on the surface of roller and temperature controller.
