SPUN TWISTER

The Spun Twister MST Series is an advanced ring twisting machine engineered for high productivity, energy efficiency, and flexible configuration. Its modular design and independent spindle operation allow precise control over a wide range of yarn types and twist parameters. The machine supports both single and double deck configurations and is suitable for multiple applications, including apparel, carpet, and technical textiles.

Energy-saving family of spindles
Balloon limiter

LOW CONSUMPTION

Innovative Spindle Design

Spindles are the most important part of any twisting machine. The main objective of the innovative spindle design is to optimize yarn quality, productivity and energy consumption.

Lowest spindle height is adopted to greatly reduce the balloon size
Right selection of bearing and good engineering design help reduce energy consumption
Spindle and reserve disk with high-grade wear-resistant surface finish for smoother yarn path
Spindle vibration optimized with the help of advanced pot mounting system

Variety of spindle options to choose for various count and package size
Large feed packages can be used due to optimized spindle pot design
Optimized spindle spacing allows low space requirement
Low power consumption due to application-specific spindle sizes

Drive Concepts

For different market needs, Spun Twister offers two types of advanced driving systems.

ST Series addresses futuristic and advanced market needs in terms of high speed, flexibility and better control.
Where as ST Series is optimized for simple yet robust driving systems.

ST Series

(Mechanical Gear Box)

Mechanical setting of TPM, crossing angle, package build-up, twist direction
Delivery speed up to 70 m/min
6" fixed mechanical traverse guide cam drive
RPM changes via inverter
Lubrication: oil
Mechanically controlled anti-patterning device
Low-maintenance construction

ST Series Features

Delivery speed up to 120 m/min
Continuously adjustable spindle speed and twist amount
Spindle speed, twist per meter, take-up package shapes, traverse length, traverse crossing angles – all adjustable through servo-driven control panel (ideal for users needing frequent setting changes)
Electronically controlled anti-patterning device
Advanced friction reduction during machine startup and stop for perfect yarn twist
Oil-free, low-maintenance construction

TAKE-UP PACKAGES

The ST Series take-up is designed for a uniform and homogeneous package building while optimising quality of the twisted yarn. It Uses high quality materials for overfeed discs, transfer tail rod, traversing guide, friction roller for a high quality yarns.

The cradle design is adjustable for tapered and cylindrical tubes for cross-wound delivery packages of size 6", 7, 8" up to a diameter of 300 mm in formats of 3°30', 4°20' and 5°57'. The die-cast cradle helps in attaining higher take-up speeds.

WAXING DEVICE

Thanks to magnetic compensation waxing device grants a constant wax distribution over the yarn.

HANDLING YARN BREAKAGE

There is a dropper system which constantly monitor the yarn balloon tension. In case the yarn balloon tension drops due to yarn breakage or once the feed package has been unwound. It automatically triggers the spindle stop action and auto lift up of the cradle to prevent further yarn take-up.

BALL YARN BRAKE TENSIONER & DEFLECTION TENSIONER

The new, self-cleaning ball yarn brake tensioner offers a single ceramic ball, adjustable by simply turning of the yarn inlet tube, covers a large braking range and replaces the time-consuming replacement of tension capsules. The tensioner come with interchangeable spring pistons for different counts and materials.

Tension can be adjusted with 8 different positions.

Deflection tensioner comes as an additional tensioner. Addition deflection tensioner comes handy for added tension management with uniform tension in each position.

TOUCH PANEL

Touch Panel for Easy to adjust parameters

1.⁠ ⁠Spindle Speed

2.⁠ ⁠Twist levels, twist direction and crossing angles

3.⁠ ⁠Machine automatic stop when yarn length &/or running times have been reached (Optional)

4.⁠ ⁠Parameters for take-up package shape and package density

5.⁠ ⁠Yarn material details

The production parameters entered can be stored in an Article library and called up whenever required. Advance Reporting available like, delivery speed, operating hours, Spindle wise breakage report, production, operator efficiency etc. The computer is equipped with a USB Connection.

BUNCHING FOR TRANSFER TAIL (OPTIONAL)

Bunching device facilitates the winding of transfer tail. The groves on the bunching device act as an automatic length counting for transfer tail. This adds to uniform length of transfer tail. This short length of yarn may be used later to join packages together.

CREELS AND CONVEYOR BELT (OPTIONAL)

In order to improve the ergonomics, the package conveyor belt has been designed so that Final Twisted packages can be removed laterally at exit point. This measure allows for a further reduction in operating time when handling large volumes of yarn.

Creels for packages and empty tubes. Creel and storage facilities for Finished packages and empty tubes to reduce handling time.

PACKAGE LIFT - OFF FEATURE

Following a time delay, the pneumatic package liftoff device takes the completed package off the drive drum, avoiding any unnecessary rubbing of the package surface.
