For W664-81, subclass for attaching elastic to bed sheets, we used until now the MD011, stepping motor driven metering device. To guarantee more accurate metering of elastic, the MD - controller was changed to MD520. It is basically the same principle like MD441 and the operator panel is also very similar to the small and easy to operate MD441 - operator panel:

Controller of the MD520

• 26 programs are available
• 5 steps within each program
• 7 different tensions within each step

The Controller corresponds to CE - regulations and is manufactured in Japan to guarantee high quality and reliability.
