RIETER D 35(40) AND APEX DRAW FRAME LOAD GAUGE


When we suggested , way back in 2000 that our gauges  be used to measure the loads of drafting top rollers of Rieter Draw frames, we met with scorns and negative remarks.  ” What ? Rieter machines ? Why do they need measurement ? We do not need such instruments. ”

We patiently explained that already our gauges had proved a terrific success with the SB &  RSB 1, 2, 51, 851 and 951 machines. Also, since the spring loaded top rollers definitely needed measurements, they agreed for a demonstration. They saw that, the top roller loads never remained uniform – despite  perfect grinding of the top roller cot, correct alignment of rollers , good original top rollers and correct setting with the height gauge.

In some machines, the variations remained minimal. In some variations went beyond 10% even to 15%. Another factor observed was that the end to end loads were not equal ! When these were adjusted, the smile was also back on the maintenance manager as he now had a sliver far better than earlier times, CV , Uster all improved. (In this blog, I have given some actual results compiled from Spinners)

Look at this picture of Rieter drafting setup. There are four rollers. The front one is actually a guiding roll with less load of 15 Kg/ end. The rear three are the actual drafting rollers with load of 30 Kg/end.

The procedure to adjust loads are given in this picture

Now, till date, we have sold more than a thousand Apex  draw frame load gauges and most of  the gauges were sold with adaptors for Rieter draw Frames. Our love story with leading brands of machinery continues.
