RSB and SB Draw Frames and Drafting Load measurement with Apex Gauges

Rieter launched their famous RSB draw frames about fifteen years back which still remains the main workhorse in many spinning preparatory departments. The testimony to its success is that the same model is still in production (Lakshmi LRSB 851) in India.  Rieter models still retain  the core design intact.

Lakshmi has this machine in single delivery design. Rieter has the double delivery model SB 20 (formerly SB 2). The drafting system in all these machine are same. The main features of the drafting setup 9with respect to loading)  are

1. Flat bed drafting

2. Three over three drafting.

3. Spring loaded top rollers.

4. Short top rollers to reduce bending of rollers and for even distribution of nipping load to the bottom roller (and the sliver)

5. All the rollers are equally loaded. (32.5 Kg each at ends in all rollers)

6. Adjustment of rollers are possible for all the rollers of one end by moving the locking hook of the loading arms up and down.

7. Each loading cell of the top roller has a spring housed in a casing with fixed loading. (with no provisions for adjustment)

8. Adjustment of loads and equalization are extremely important. Variations of even 1.5 Kg have shown Uster variations. Similarly difference in end  to end loads affect CV % and  Uster .

TEXPARTS PK 1500 TOP ARM AND LOAD ADJUSTMENT

Texparts has another trusted speed frame drafting top arm PK 1500 which has found wide acceptance with cotton and synthetic spinners.

This is a spring loading top arm much like its predecessor SKF 1600-40 top arm. This top arm is available in 4 roller and 3 roller versions.

The four Roller version is here

The load setting values for this top arm is here

Similarly the 3 roller drafting is below

And the load setting values for 3 Roller drafting is here below

Conversion: 1 daN(Deca Newton) = 1 Kg

The above loads are variable in steps only by shifting the loading nuts by a special lever. Apart from these , the cumulative load can be increased or decreased by the two setting screws provided at the back of the top arm.

Needless to say, our Apex Top Arm Load Gauges were very successfully used to measure the top arm loads in PK 1500 top arms. Very accurate and reliable, these gauges are the favourite of many a quality conscious spinner. Click on the following link to read on our Apex Top Arm Load Gauge with a video demonstration.

TEXPARTS PK 5025 TOP ARM AND APEX TOP ARM LOAD GAUGE

Texparts PK 5025 top arm is a trend setting one in that it carries new design features hitherto unknown in textile drafting.

First, the old concept of individual loading is dispensed with. Second , a pneumatic spring has been employed for load generation.  One may argue that the same principle was used by RIETER in their FS 160 and the later P3 drafting series.

The difference between them is that Rieter design loads the arm near the pivoting point. But in Texparts, the pneumatic spring (a pressurised hose) actually runs through the length of the top arm loading each saddle . This is a fresh outlook at top arm design and going by the customer review and the work it is doing in the spinning floor, the design seems validated and a viable and trouble free one.

They are available in two models. A four roller drafting and a three roller one.

The load setting values are given below.

3 Roller Version & 4 Roller Version

Apex top Arm Load Gauges are the most trusted ones for a keen eyed spinner who wants to keep a close watch over the loads and general behaviour of drafting apparatus. Our gauges are easy to use , easy to understand and trouble free. Their strict calibration checks at our factory ensure that each one measures the exact load every time.

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.

TEXPARTS PK 2025 TOP ARM AND APEX TOP ARM LOAD GAUGE

PK 2025 Top Arm

PK 2025 is one of the largest working top arms in the spinning industry today. It is an advanced one than its predecessor, the hugely popular SKF PK 225 top arm. SKF PK 225 is still continued to be produced in India and similar designs are also coming out of China.

But PK 2025 is another class act altogether. It retains some basic similarities  with PK 225 like

1. The front saddle has three adjustable load steps – 10 Kg (Black), 14 Kg (green) and 18 Kg (Red)

2. The same drafting geometry with parallel top and bottom rollers.

3. Rigid spring housing design.

4. Handle and rear load setting screw set up.

The improvement is there in middle and back roller load setting adjustment. Earlier in PK 225, only the front roller had load adjustment. Here, all the rollers have the facility. This is a significant one.  The older one had a problem in that the middle and back roller loads could not be changed independently. In other words, the increase in loads of middle and back rollers simultaneously increased the front roller load. Now, this problem is rectified in PK 2025. Look at this picture from Texparts

Apex Top Arm Load Gauge and PK 2025 Top Arm

Using the Apex Top Arm Load Gauge in combination with the PK 2025 top arm is the most ideal. After the load is set, the gauge is held in the saddle of the top arm and pressed.   Usually, we see variations from one top arm to another  even after the feeler gauge is used.

This variation can be attributed to manufacturing tolerances of the top arm. Due to this many spinners have abandoned the feeler gauge and instead use our Apex Top Arm Load Gauge. We know this is a loaded statement but we stand by what we say. The proof is with the spinners who use the gauges.

Research links Top Arm Load to yarn quality

Research links Top Arm Load to yarn quality

Dear Spinner,

A research done at Department of Textile Technology at the Indian institute of technology by Researchers.

They have concluded that   “The top arm pressure and roller setting influence the yarn properties at all three drafting stages almost in similar way. With the increase of top arm pressure and roller setting the yarn tenacity increases initially up to a point and then decreases. Yarn unevenness, imperfections and hairiness shows an initial decrease up to a point with the increase of the above two parameters. In general, the moderate level of top arm pressure and roller setting gives better results.”

Apex Comber Detaching Roller Load Gauges

Now, measure the drafting load in Comber Detaching Roller too !

For the first time in the world, a gauge was developed at Apex Precitech to measure the Detaching Top Roller of a Comber.

This gauge resembles the famed Apex Draw Frame Load Gauge but the construction has been modified to suit the lesser detaching top roller loads.

The gauge assembly is shown here. The gauge has two gauge blocks at each end with a capacity to measure the end loads of the top roller individually and independently. This is the greatest advantage in using this particular design feature. By adjusting the top roller loads individually and equalizing them, individual sliver variations can be controlled. Also, the over loading of the Detaching roller is also avoided.

This gauge is now suitable for almost all the Combers in use in the world today like

Lakhmi Rieter- E 7/4, LK 250, LK 54

Rieter- E 7/5(&5A), E 7/6, E 60 (60 H),62,65,70

Cherry Hara: VC 300, VC 300 A

Others like: Vouk, Marzoli, Howa, Zinser etc

Please view the live demonstration of this gauge on a Comber in a mil by clicink on the play buttonl. The machine is an E 7/4 comber.

Apex Draw Frame Load gauge

Apex Draw Frame Load gauge is a path breaking product from us which was arguably the first comprehensive instrument in the market which can measure ALL the draw frames in use in the market. A unique double gauge design, a sliding type of assembly of the gauges and direct reading of the Top Roller Load in Kilogram units made this product very famous. Most of the quality oriented Mills and exporters are its regular users.

In addition to draw frames, this gauge can also measure drafting loads in Comber draw boxes and Lapformer draw boxes.

Construction

This gauge has two mirror image type of measuring blocks to measure the end loads of the top roller at the left and right end individually. The dials are calibrated directly in Kilogram units and three separate scales are provided in each dial so that the user can get the reading for any set of machinery straightaway without manual calculations.

Adaptability

This gauge is adaptable to almost all the draw frames in the market such as DO 2S, DO 6, RSB, (1, 2,51,851 & 951)D 10, 20,35,45, ZINSER 720, (4/3 &5/3), ZINSER 730, TRUTZSCHLER HSR 900 & 1000, TD 03, HOWA DF K2CD, CHERRY (400,500,600,800, DX LT,DX 7A, DX 8), VOUK SFH, 802 E and many others.

Also combers such as E 7/2, E 7/4, VC 300, 300 A, VOUK, MArzoli, LK 54, LK 250, and many others. (Please note Rieter combers E7/5, 6, E 60, 60 H,62, 70 cannot be measured with our gauge since the drafting is a closed one and the gauge cannot be placed on the saddle)

Lapformers like E2/4A (SLIVER LAP), E 4/1A(RIBBON LAP), HILAP 85, 100, RITER UNILAP E 32, VOUK , HOWA AND MARXOLI LAPFORMERS.

Spares for measurement

Adaptors for each draw frames are to be bought by the customer by filling a questionaire which can be found by clicking here. For any given draw frame, comber or lapformer one set of adaptor has to be bought. Each set of such adaptor contains two end bushes, one centre rod and rollers representing the cot (rubber cover) diameters running in that respective machine.

Rules for Load setting:

Each machine manufacturer has specified load setting values for their machines which can be found by clicking here. The gauge is a user-friendly one which requires a training of less than 30 minutes for even a layman.

Demostration:

The following video shows how the gauge can be used in a draw frame. As a sample case the way of measurement is shown in a RSB draw frame.
