Un-Winder Unit:

The provision of mechanical clutches on both sides of spindles help to ensure holding the heavy roll without tilting or falling dawn during the operation and also easy to change the fabric rolls. The system provides two fabric rolls each having 1000mm dia. and this will help to reduce the operational cost as there is no need for switching off the plant for changing the fabric roll. The Linear bearings (4-Pairs) provided holds the entire un-winder frame and helps to move side wise very smoothly and allow the fabric is delivered accurately to the printer.

Digital Center Guide System [Optional]

The objective of above system is to have printing in center of the fabric irrespective of width variation in fabric. The system gives you more effective performance in case of Laminated Fabric. In case of laminated fabric the edge of the laminated poly is always uneven. (Variation with respect to fabric edge) In this case if we take the reference of poly edge it will give uneven printing. We have specialized fabric sensor, which will sense the edge of fabric irrespective of poly variation and guide the material in reference of fabric edge.

Moving Sensor Center Guide System

Center Guide System keeps the centerline of the web in exact position irrespective of any width variation. This system will guide your fabric with respect to center in reference of fabric edge.
It consists of:
Opto. Electronic Sensors - 2 Nos.
This is a versatile technology. It can be used as Center Guide & Edge Guide also. In case of laminated fabric it can sense edge of the fabric not the edge of poly. In case of Un-laminated it will sense edge of the fabric. Suppose we are printing a 24” Laminated fabric. Irrespective of poly width out side the fabric edge both the sensor will sense the edge of fabric. The system will keep the center in exact position at 12”. Now whenever any width variation comes in the fabric the sensor will move automatically inside or outside & keep the center of the fabric. This will give the Printing with respect to center of the fabric.

5. Infra Red Lamp

Sar Industries is always in the forefront to innovate solutions to many a problem that HDPE/PP bag manufacturers / printers face. A major problem the printers have to overcome was high drying time for ink printed on bags. Un-dried bags when bundled would spoil the backside of the bags with inks impressions which cause of high ratio of rejection by the ultimate customer. With abundant order in hand and slow drying process they find difficulty in meeting their production target. We then came with an idea of installing Infra-Red Lamp of 1000W, 240Volts capacity to bring down the drying time from minutes to seconds. These Lamps fitted at the delivery end of the printer provide spot heat up to350’C and when it focuses on the moving bags they get dried swiftly. We have offered this to our valued customers who have appreciated our suggestion, which helped to improve their production as the drying time has been brought under control with just one unit of electricity an hour or so.

6. Mixing Machine

mm We are very pleased to introduce yet another innovation to woven sacks industry. It will certainly minimize your problems in mixing of raw materials perfectly.
The salient features of our mixing machine are:
1. Reduction of man power working
2. Reduction of mixing time
3. Reduction of mishandling
4. Improves quality of end product

7. Online Screen Changer

changer Advantage [Manual to Self Cleaning]:
  1. Absolutely eliminated leakage problem
  2. Absolutely eliminated ideal time
  3. Maximum utilization of tape plant
  4. Elimination of material wastage (Due to nonstop of line)
  5. Easy to Operate
  6. Use any type of CaCo3 and up to 20%
  7. In Self Cleaning Continuous Screen Changer, Screen will be changed after 15 days.

A. Reduction in Wastage (Stoppage):

If we are using 14% ~ 18% CaCo3 of first grade supplier the Normal Screen Changer requires min. one stoppage in a day. If we are using second grade CaCo3 that requires two stoppages. But if we are going for On Line Self Cleaning Screen Changer, we don’t need to stop plant. Hence, we saved min. 20 kg of wastage per stoppage.
Wastage per Month in normal screen changer           =   20 Kgs X 30 stoppages   = 600 Kgs
Wastage per Month in self-cleaning screen changer   =   20 Kgs X 2 Stoppage      = 40 Kgs
Total Saving per Month                                        =  560 Kgs per month

Reduction in Running Wastage:

In normal case, when we starts tape line wastages very nil but when time increases percentage of wastages goes high it shows that when mesh starts chocking it increases the wastage and reduces the production.
Wastage per Month in normal screen changer          = 40 Kgs X 30 days               = 1200 Kgs
Wastage per Month in self-cleaning screen changer  = 30 Kgs X 30 day                = 900 Kgs
Total Saving Per Month                                       = 300 Kgs per month

C.Quality and Efficiency Enhancement:

If we maintain speed of godets as well as main motor rpm remains same and we replace normal screen changer to on line self cleaning screen changer the quality of product comes very proper and equal.

D. Power Saving:

In each stoppage it takes minimum of 20 minutes to stop + 60 minutes to change mesh + 20 minutes to start = The total time is 100 minutes.
In whole of this time total system is ON means power loss is 60 minutes of working load = 150 Units [Power Saving Per Month =150 Units X 30 = 4500 Units]

E. Production Enhancement:

If we don’t stop the plant twice in day we will get minimum one-hour production more.
One hour production = 150 ~200 Kg.
Hence, the pay back period is only 2-3 months.

8. Six Station Cutters

station cutter Advantage [Single Station to Six Satiation Cutter]:
  1. Absolutely eliminated ideal time
  2. Maximum utilization of tape plant
  3. Easy to Operate
  4. In Six Station Cutter, Blades will be changed after 6 days.
A. Power Saving:
In each stoppage it takes minimum of
20 minutes to stop + 60 minutes to change blade + 20 minutes to start
= The total time is 100 minutes
In whole of this time total system is ON means power loss is
60 minutes of working load
= 150 Units
[Power Saving Per Month =150 Units X 30 = 4500 Units]

B. Production Enhancement:
If we don’t stop the plant twice in day we will get minimum one-hour production more.
One hour production = 150 ~200 Kg.
Hence, the payback period is only 2-3 months.
Six Station Cutter Consisting:
  1. Powder coated cutter assembly
  2. Cutter frame with cover & one roller
  3. One set of shaft
  4. Spacer duly assembled with super max blade
  5. Cutter Stand

9. Gear Box Cooling System

Gear You are aware that Gear Box is a very important part of the Tape Plant. Very often the excess heat generated by gears cause its expansion, consumption of excess power and more expenditure on cooling oil. We in SAR INDUSTRIES has innovated a solution to reduce the heat so generated by a method of using an external cooling system to Main Gear Box at a very reasonable cost.
This will ensure increased life to your Gear Box and also Gear Oil. The Gear Box Oil which reaches above 70’C due to continuous running of the plant has to be brought down to a minimum to safeguard the gear as well as gear oil. In a Cooling System that we offer, the oil in the gear box with high temperature is taken out to heat exchanger tank having lines of water circulation pipe from a chilling plant.
The motor-pump combination attached on the oil circulating system pushes the oil via heat exchanger to gear box. The process ensures the gear oil to maintain a temperature between 45’C – 55’C which is safe for the gear system.
