The term ´SLUB´ is described as ´Thick Place´ in a yarn. In slub yarn, ´slubs´ are deliberately created to produce a desired pattern in the yarn. By altering the slub yarn parameters such as slub diameter, slub length and yarn length or slub interval, one can produce more varieties of slub yarn with different styles.
Long ring frame is nothing but a ring frame having Duoflex drive at ´OFF end´ (like LR6 series up to 1,200 spindles). For Duoflex drive ring frame, ´DS2L´ model is designed for slub. In this model, middle and back bottom fluted roller of the ring frame must be split at the middle to provide separate drives for both the ends.
Instead of machine drive, two servo motors are used to drive the middle and back bottom fluted roller (one at ´Gear end´ and another at ´Off end´). Two sets of specially designed servo drive, Servo motor and a sturdy SKAAT variator gear box are used to drive both ´Gear end´ and ´Off end´ of the ring frame independently without slippage. Drive transmission by means of ´mechanical coupling´ at Gear end and ´wheel drive´ at off-end. Both the servo motors are synchronized to produce uniform quality of slub yarn.
Gear end of the machine is entirely covered by a special panel. All the drive, motor and electrical components are placed inside this panel. Touch industrial computer with 15´ wide screen is provided on the panel for easy view and hassle free programming.
DS3L: This machine is specially designed for very long ring frames with more than 1632 spindles. In this model three servomotors are used to drive the rollers.
DS2L: This machine is designed for long ring frames, i.e. ring frames with 1,200 spindles. Two servo motors are used to drive the split rollers.
DS2: this model is designed for medium ring frames, i.e. ring frames with 1,008 spindles. Entire frame is driven by a single servo.
SKATT DIGI 300 slub attachment is designed for any old make of short frames up to 600 spindles. The entire drive units and control panel is to be placed on gear end and a 15´ touch industrial computer will be kept near by the machine for programming. One sero meter is used to drive the middle and back bottom roller through a specially designed SKAAT variator gear box. Drive transmission from servo motor to middle and back bottom fluted roller by means of gear to avoid slippage and unwanted jerks on the machine.
In all the models, two advanced digital encoders are used to monitor the speed of front roller and back roller separately which ensures that this speed ratio is always matching with servo speed to produce uniform quality of slub yarn, while the machine is running in variable spindle speed. Back roller encoders also act as ´slub missing stop motion´ which is used to stop the machine immediately whenever the slub action has not taken place.
