It is equipped with advanced technology for optimum energy efficiency and quality of production. Its scientific design and well studied execution ensures aerodynamic air flow, considerably reducing the energy consumption. The streamlined construction enables easy approach to all components and ease of maintenance. The machine can be supplied suitable for various heating media like Steam, Thermic Oil circulation, direct fired Gas etc.

Stenter - Fabric Feeding

The In-feed system can be supplied suitable to take up fabrics either from batches or loose folds. The machine can be supplied with a J-Scray or an Accumulator for continuous operation. OPTIMA 2510 Stenters are provided with very efficient un-curlers and Infra-Red Edge Sensors which actuate the in-feed device provided with Rack and Pinion system, ensuring perfect fabric holding in clips or pins even at high speeds exceeding 100 meters per minute.

Stenter - Over Feed

A simple and accurate over-feed system using Variable Frequency Drives with AC Geared Motors ensures perfect and precise Over-feed control as required by the fabric, ranging from -10% to +50% by control of motor speed. It is very simple and easy to maintain. Separate drives control the Fabric Tension and Selvedge Tension rollers. A closed loop control system with encoder can be provided for precise control of the drives.

Stenter - Weft Shrinkage

Conicity of rails can be easily obtained by acting upon the individual width controlling screws of each compartment, de-clutching the individual unit from the main width adjustment control system and adjusting the individual rail to precise requirements, by acting upon each gear box provided on individual adjusting screw with the help of a hand-wheel. A suitable indication is provided on each gear box for precise control. It can also be automatically regulated as pre-programmed by acting on individual motors, with PLC Control.

Stenter - Chain Rails

Properly seasoned Cast Iron chain rail guides are provided to support the moving pin clip chain. They are strong and distortion free even when operating at elevated operating temperatures and at speeds in excess of 150 meters per min. Various combination of entry and exit chain rails are supplied for different applications. Extended entry rail track up to 6.3 meters can be provided which can support the Fabric feeding device, the Steaming device, Selvedge Gumming and pre-drying unit etc. Extended exit rail tracks up to 5.8 meters length can support the conventional Air Cooling zone, Selvedge Trimmer, Chain cleaning device etc.

The clips are made of several individual, pressure die-cast, easily replaceable components. These components are made from special corrosion-resistant aluminum alloy and are distortion-proof even at the high heat setting temperatures, These components are very well studied to the lowest individual details and are designed to ensure long trouble-free performance with all kinds of fabrics. The steel shoe holding the clips are fitted with sintered metal liners and connected with steel links. The roller chain glides smoothly on special cast iron rails. The superb sliding properties of sintered metal considerably reduces lubrication requirements even at the high heat setting temperatures, thus ensuring safe operation and long life. On request, the machine can be equipped with special polymer liners for lubrication free working. Optima 2610 is equipped with a vertical return pin chain.

Stenter - Chain Cleaning Device

SWASTIK OPTIMA 2510 can be equipped with a suitable chain cleaning device with steam, consisting of a set of hard-chrome plated nozzles with flexible steam connections, for easy and fast cleaning of pin-clip chain.

A simple motorised, quick acting two-roller Bow and four roller Skew Weft Corrector is provided for efficient correction of weft distortions. Alternatively, on request, the machine can be equipped with Automatic Weft Corrector with optical sensors and digital control. Additional sensors can be fixed on the machine exit to ensure perfect weft straitening.

Stenter - Width Adjustment

The OPTIMA 2510 is equipped with a standard motorised width adjustment device with common shaft with gear boxes mounted on top of the dryer. The width adjustment device is controlled from the control desk by means of push buttons. Setting of individual screws can be done by means of a handwheel acting through the clutch on individual gear boxes. The OPTIMA 2510 can also be equipped with individual motors and controllers for the individual screws which are controlled from the control desk either individually or all at a time. A suitable indicating arrangement is provided on the Operator Console.

DRYER MODEL RDB 3000 is a modular dryer which can be assembled as required. The low volume design Dryer RDB - 3000 is equipped with a specially designed duct with the Heat Exchanger / Burner at one end. The Blower is fixed at the other end. The inter-connecting duct does not permit any infiltration of air into the circuit without heating. Jet nozzles are designed to obtain maximum evaporation from the fabric and are specially designed for the specific fabric requirements. The Dryer RDB - 3000 is a compact, sturdy, simple and efficient Dryer equipped with a closed circuit air circulation system, using Radial Blowers directly coupled with AC motors which can be controlled by Invertors. Basically the RDB - 3000 occupies less space and has lower energy consumption. All drive elements are fixed outside the heated area and are accessible from outside. The Dryer RDB 3000 is equipped with insulating panels filled with high density insulating material for minimum radiation losses. Specially designed jet nozzles at the entry and delivery end ensure minimum heat loss through escaping hot air.

The blowers are mounted directly on the motors mounted outside the machine and are easily accessible. The blower speed is regulated through Variable Frequency Drives.The high volume jet nozzle elements are specially designed for perfectly even air flow to the fabric. The special design provides better fabric support, gentle heat transfer and reduced energy intake. Different nozzle shapes for different applications ensures higher productivity for different quality and types of fabrics, distortion free for delicate and knitted fabrics and are suitable even for pile fabrics. Air distribution to the fabric from the top and bottom nozzles is regulated through dampers fixed in the circuit. The dryer RDB 3000 can be supplied with different heating media. The machine is equipped with multi-pass finned tube type heat exchangers with a large heat exchange surface for quick heating with Steam or Hot oil circulation or large firing area for Direct fired Gas Burners.

Tubular Heat Setting Machine Model THS - 1 and THS - 2 for Heat Setting with Hot Air Circulating System for all synthetic fabrics and their blends with Cotton, Lycra Polyester / Lycra Nylon or Elastene Blends etc. The Heat Setting machine THS is used to achieve results on knit tubular fabric, which were only possible until now with open-width fabric treated on a Stenter. It also avoids the problems and difficult handling that are faced when fabric has to be processed in open width. The Heat Setting Machine is used for the pre-setting of Lycra / Elastene blends with cotton or synthetic fibres before the wet processing of the gray fabric, as well as the Heat Setting of synthetic fabrics and blends, if finished in tubular form. The Heat Setting machine THS is equipped with specially designed adjustable Stainless Steel Frames. Machine is equipped with Radial Blowers, one per section, a Natural Gas Burner or Thermic Fluid Heater, Nozzle Systems for uniform distribution of the re-circulating hot air and a suitable duct. The maximum temperature can be achieved up to 220 degree C. The machine is suitable for One, Two or Three Tubes. The Cooling Zone at exit is provided to bring fabric temperature close to ambient and a Plaiter is provided at the delivery. The machine is equipped with a Control Panel with a VFD, Temperature Controller and other accessories.
