  With fibers being recycled again and again, the inherent strength of paper falls; fibers become less flexible, less permeable and harder to process. Starch spraying system boosts the strength of the paper. The system uses quality precision nozzles to discharge a suspended starch solution to the fiber web of the paper. Amount of the starch solution sprayed and proper mixing of chemicals is very critical in deciding the quality and strength of the paper.       If your starch spraying system isn’t performing optimally, you could be faced with these problems: • Quality control issues • Unscheduled production downtime • Increased maintenance • Increased consumption of chemicals, water and electricity • Environmental issues   The cost of wasted water alone can quickly amount to tens of thousand of rupees in a spray system that is not optimized.   System advantages :   1. Unique nozzle cleaning by linear brush movement 2. Fully automatic, semi-automatic or manual activation of brushes available 3. Can be operated via control panel or hand wheel 4. Simple attachment possible to give fully automatic brush activation 5. Optimum operation with process water up to 800 ppm guaranteed 6. No process water pre-clarification by expensive filters required 7. No additional in-line filtering required 8. Effective fabric and felt cleaning can be achieved even with inferior water quality 9. Simple installation, uncomplicated exchange of nozzle inserts and cleaning brushes

The S.S self cleaning shower comes with a disc type jet nozzle & a brush assembly. In order to achieve the desired quality of paper it is necessary that the shower systems are in place. To achieve optimum and effective spray of water, the spray angle has been maintained at 60o . This ensures that the felt is covered completely by the shower system. It utilizes a hand wheel to rotate the brush assembly. The brushes do not shut down the spraying operation. The shower continues to spray during the flush out operation. The brush sections are staggered at 120o intervals along the shower. Large passages between the brush sections allow full flow while the system operates. Brush interference with the nozzle inlet does not adversely affect the performance when the flush out valve is in the full operating position.   Features :   1. Shower piping is 316 Stainless Steel 2. Nozzle type, orifice size and spacing are carefully matched to the shower’s application 3. Nozzle basses are welded to the pipe 4. Brush assembly to perform cleaning operation.     Advantages : 1. Rugged in construction 2. Simple in Operation 3. Back water can be used 4. Cleaning operation performed in minutes. 5. Ideal for other papermaking application. 6. Improves quality of paper.  

The Pneumatic Auto Guide System (Piston Type) are designed for use in wire, press and dryer section of paper machines. All piston guides have a compact, enclosed design.     Features : 1. The portion of sensing palm that comes in contact with the fabric is fitted with a ceramic coated strip thus giving a very long life to the palm and also avoids any damage to the fabric due to wear on the sensing palm. 2. Suitable for wires, felts & dryer fabrics 3. Normal working pressure @ 3.0 Kg/cm2 4. Adjustable stroke, maximum stroke upto 60 mm on either side 5. Returns to central or present position in the event of air system failure 6. Built in manual over ride.   Advantages : 1. Robust, enclosed design 2. Mechanical feedback unit for excellent guiding results 3. Low internal friction 4. Flexible mounting position 5. Maintenance friendly

Type : D

    Felt and Wire Auto Guide Systems are designed to keep the wire running properly in the center of the roll over which it travels. If you loose control over your wire felt or fabric, the cost incurred in damaged clothing is high. Lost production can make such accidents extremely irritating and costly. Installing the reliable and well proven automatic wire and felt guiding system represents an easy way and inexpensive way to avoid this problem. It comprises of an actuator and pneumatic controller with ceramic coated palm assembly, the Auto Guide works without sliding surfaces.   Advantages : 1. Avoid Fabric run off 2. Minimize fabric edge wear 3. Reach Maximum fabric wear life 4. Reduce sheet breaks 5. Optimize paper productivity   Salient Features : 1. Immediate response to any movement of the clothing in the cross machine direction without overcompensation 2. Very few moving parts and little need for maintenance work. 3. Moving parts are fully enclosed for complete protection against water, fiber and dust 4. Extremely low compressed air consumption, normal working pressure @ 3.0 kg/cm2 5. Suited for installation in any position- horizontal, vertical, inclined or even upside down. 6. Easy to install and operate. 7. No adjustment required before start up 8. Built in manual over ride  

        An oscillating type of shower provides continuous movement of the shower to assure complete & uniform coverage with minimal wastage. It consists of a gear motor assembly which is connected to an eccentric disc. This disc converts the rotational motion to lateral motion of the shower, thereby ensuring proper spray on the wire. Precision nozzles ensure that the water is sprayed uniformly over the wire. The shower system is also fitted with a brush assembly which helps in proper cleaning of the shower. The brush assembly consists of set of nylon brushes and a hand wheel. They are designed in such a manner that their interference does not restrict the flow of water through the nozzles. Oscillating showers are used in all types of applications where high-pressure water jets are required to clean paper machine fabrics or cylinders. If these showers were not oscillating, the high-pressure jet impact would otherwise damage the fabric or cylinder.   Features : 1. Shower piping is 316 Stainless Steel 2. Nozzle type, orifice size and spacing are carefully matched to the shower’s application 3. Nozzle basses are welded to the pipe 4. Brush assembly to perform cleaning operation. 5. +/- 100 mm stroke length.   Advantages : 1. Rugged in construction 2. Simple in Operation 3. Operates at High Pressures 4. Ideal for many papermaking application
