Technical Specification  :

   Static Eliminator :    

Introduction :
During the manufacturing process, wherever two materials which are non-conductive rub with each other relatively high speed Static Electric Charge is generated

How PLATEX static charge eliminator works :
Eliminator Bars which are fixed as near as possible to the material in process, on getting supply from control unit ionize the surrounding air and because of this Static Electric Charge is conducted away to the ground.

Application :
Extruded Tube / Film Plant, Tape Plant, Cutting and sealing machines, printing machines. Textile Processing Machines, Coating Machines, Photographic Film Processing and cleaning units.

   Yarn Detectors :    

Features :
● Contact less sensing of yarn. Hence no additional tension on yarn.
● Mechanical linkages & wear of moving parts as in Electromechanical stop motion levers are eliminated
● Increased reliability in detection & trouble free operations over long periods
● Unaffected by dirt, yarn colours, yarn material & finish
● Various optical sensors designed to suit different applications
● Compact & rugged design
● Improved sensing area permits sensing of finest of yarns with improved reliability under extreme conditions of dirt & oil
● Detection can be achieved on all types of moving yarns - Traversing, Ballooning or yarn moving in straight line
● On detection appropriate control signal can be generated through allied circuitry to suit specific requirements
● The control logic unit can be mounted in a convenient position & can be designed to suit specific requirements
● The unit is suitable for operating a wide range of devices including cutters, relays, solenoids, warning lamps, hooters etc.

Specifications :
● SUPPLY : Standard Sensors are suitable for 6VDC or 12-30 VDC. However they can be designed to suit any suitable supply at customers end.

   1] Transistor output either PNP or NPN, 100 mA Sinking.
   2] Logic Output
   3] Relay Output
       As specified by customer

Ambient Conditions : Designed to withstand vibrations & temperature ranging from -5 ºC to 50 ºC

   Optical Weft Feeler Type RTL :    

Specially developed to replace mechanical and electrical feelers, as weaving of filament yarn prohibits sensing of WEFT with physical contact, which causes filamentation and WEFT breakages.

Principle :
Reflective tape is a fixed over the pirn at specified position. the optical sensor is mounted on the slay cap. When the weft is about to runout, the reflective tape gets exposed. At this instance the light signal transmitted from the sensor is reflected back to the sensor. This signal is amplified by the control circuit to actuate the pirn changing mechanism or to stop the loom through a solenoid.

Advantages
● It only requires pirn preparation with reflective tape. No special shuttle or pirn is required.
● Sensing can be done from any direction, hence it has no limitation of a fixed location.
● It is also suitable for circular looms.

Technical Specification  :

   Optical Weft Feelers :    

Designed to stop the loom or to actuate the pirn changing mechanism before weft yarn the pirn runsout completely

● Provides contactless sensing of weft yarn.
● Eliminates defects like weft bars., double picks, cracks etc.
● Reduces weft wastage.
● Suitable for weaving quality fabrics in cotton, silk, art silk, spun yarns, woolen or worsted, filament yarns and
   their blends
● Increases productivity of loom
● Infrared light source and solid state circuitry gives trouble free service over long periods
● Almost negligible maintenance & repairs/ replacement cost
● Suitable design is available for every type of loom

   Optical Weft Feeler Type LPC / LPC IR :    

It requires a shuttle with a closed bottom and a slot. The pirn with a hole or a slot will align with the shuttle slot when fitted in the shuttle. Light from the transmitter (incandescent / infrred) monitors weft yarn condition over the pirn during weaving process. When the weft is about to runout, light passes through the slot of the pirn & the shuttle, to the feeler head embedded in the slay. Electrical signal thus produced is amplified  in the the feeler head embedded in the slay. Electrical signal thus produced is amplified in the control circuit to energize the solenoid through relay contact. this solenoid is suitably mounted on the loom to disengage the startling handle for stopping the loom

Salient Features
● Indispensable for Dobby and Jacquard design weaving.
● No bunch winding is required
● Suitable for non-automatic power looms and automatic shuttle changing looms.

Technical Specifications :

   Electrical Warp Stop Motion :    

Salient Design Features
● Designed to achieve cent percent efficiency
● Suitable for all types of shuttle looms and shuttleless looms.
● Universal application for weaving quality fabrics of cotton, silk, art silk, woolen or worsted, spun, filament and
   their blends
● Spark free positive detection of fallen dropper pin irrespective of fluff accumulation over the electrodes.
● Conversion of Mechanical Warp Stop Motion to electrical warp stop motion is possible with minimum modifications.
● All types of dropper pins can be used

The electrode strips provided in place of conventional serrated bars / insulated bars act as upper electrode. In addition a reciprocating Lower Electrode is provided below the dropper pins. No sooner a warp end breaks, the pin falls and makes contact with the reciprocating lower electrode. This actuates stoppage of loom. The drive for the lower electrode can wither be taken from the loom bottom shaft or from an independent motor mounted suitably.

Advantages
● Positive & quick detection of broken/slack warp end results in a better quality fabric
● Eliminations complex adjustments of Mechanical Warp Stop Motion and electrical contact area limitations of
   conventional electrical Warp Stop Motion
● The indicator is provided to attract the operator's attention for immediate rectification
● More number of looms can be allotted per weaver. This increases production per weaver
● Maintenance required is negligible

Technical Specifications :

   Optical Weft Feeler Type PT - 2 :    

● Specially developed to replace mechanical and electrical feelers to get contact less sensing of weft yarn over
   the pirns
● It does not require any pirn preparations like fixing of reflective tape on pirns or making a slot over it
● Suitable for single shuttle auto pirn changing looms

The sensing head comprise of a light transmitter, light receiver & an amplifier circuit. Modulated light falls on the pirn and is reflected. Receivers encased in the same module senses the reflected light. The control circuit differentiates the presence or absence of weft. In the case of absence of weft, it actuates pirn changing mechanism through a solenoid

Advantages :
●  The pirns do not require any preparations like fixing of reflective tape, perforation or a metallic sleeve
●  Installation is very easy
●  It is suitable as a substitute for imported feelers

Technical Specifications :

  Loom Control Panel :    

For shuttle looms to produce quality fabric at par with shuttle less loom

Salient Features : 1. Unique electronic braking is developed for induction motor. 3 phase 440 VAC / 220 VAC used for power loom 2. It stops the loom at desired loom position 3. It does not require any liner or linkages as on mechanical brake & electromagnetic brake 4. It does not require any modification in existing loom motor 5. Push button control results in easy & convenient operation to control the loom. Reduces tiredness to operator. 6. Increases efficiency of loom by reducing idle time. This is achieved by features such as,  ● Starting from one position only  ● Stopping at one position only  ● Forward & reverse inching  ● Single pick operation 7. Increases operator efficiency as each operator is able to handle more number of looms
