Relanit Technology Relanit is a modern technology for circular knitting machine. In the conventional circular knitting machine the relative action between sinker and the needle was occurred at 90° angle, but in the relanit technology the sinker and the needle action at 0°, and loop formation occurred at 0°.

Why relanit is used ? In conventional machine in time of loop formation needle gives vertical movement and sinker gives a horizontal movement. In this process needle have to descend to knock-over, which takes some time, so to minimize this time, relanit technology is innovated. In the MAYER & CHI machine this technology is used, in this technology the sinker used is different from the conventional process.

In the conventional machine, the knock-over and the clearing is given below.

The main reason for using this technique to minimize the time in every loop formation, so that fabric can be made in less time, ultimately to increases the production rate.

From the figure we can see that, the cam shape of relanit is smaller, which saves some area.

Due smaller cam shape, more no. of cam can be used in same diameter machine, which will increase the productivity of the machine.Due to smaller cam machine can run at higher speed.

For example in Fukuhara, or Orizio machine, For 30 diameter machine, maximum 90 cam box or feeder can be used

But in Mayer & Chi machine, for 30 diameters machine 96 feeders can be available (Max 120)

Ultimately in every revolution of cylinder, 6 more courses found.

From the calculation below we can found the higher productivity

If a machine runs at 30 rpm, then 6 X 30 = 180 courses /min

= 180 x60=10800 courses / hr

=180 x60x24=259200 courses /day

Draw backs of Relanit technology

Due to higher machine speed more heat will be generated so more lubricating oil is required.

some of the Mayer & Chi machine, consume extra motor power than conventional machine which also add extra cost.
