Basically slub is an effect as or a defect in yarn. Whenever yarn is over-drafted or under drafted or some foreign fibers mixed during spinning process then yarn is not suitable for making fabrics. This slub becomes valuable when we purposefully spin slub yarn with the help of SOG for making self created designs in fabric or Knitted Garments.
There are different types of Slub Yarn, like Ground Slub, Injected Slub, Multi Count Slub, BEACON Slub etc.
S.O.G. is an abbreviation of Slub-O-Generator which is used to produce slub yarn.
Normally it takes one day to install but for this Spinning machine will be stopped for few hours.
Production of Slub length depends on fiber length i.e. Minimum Slub length = 1.2 X Fiber length. There is no limit for maximum slub length.
Slub thickness can be maintained by electronic adjustment through touch screen.
In early days copper wire brush was used to transfer the current, which was costlier and having little life so copper wires are replaced with Carbon which is comparatively cheaper and having long life but still it is known as Carbon Brush similar to copper brush.
Too much hardness of spring will put excessive pressure on carbon brush which will adversely affects life of carbon brush and other parts.
It is used to make better contact and easy contact fixing.
Life of carbon brush depends on the sizes, shapes, quality, material grade, pressure on carbon brush etc. and application where it is used.
Clutch is used to control motion of the machine.
We can produce a Slub Yarn on any ring spinning machines or any open end spinning machines by accelerating back roller with the help of installing Slub-O-Generator.
Most popular models are DigitorQ™ OCGS TL-1, DigitorQ™ TCIS TL-1, DigitorQ™ MCMT TL-1, DigitorQ™ TIO TL-1, DigitorQ™ O.E. TL-1, DigitorQ™ BEACON SLUB TL-1.
DigitorQ is digital torque control technology specially developed for using with fancy yarn devices and it incorporates our in-house developed software. DigitorQ is our Trade Mark Brand.
The selling prices of slub yarn is higher than normal yarn hence payback period of S.O.G installation is very short and spinner will earn more profit by installation of Slub-O-Generator.
Yes, it is necessary to reduce the speed of the spinning machine related to different factors like, slub length, thickness, yarn count, no. of Slub, type of fiber etc.
It is used to transfer electric current from static contact to moving contact.
The spring is playing very important role to maintain proper pressure on carbon brush for making low electrical resistance contact.
Carbon brush are used in electrical machines i.e D.C Motor, A.C Slip Ring Motors, Overhead cranes, Clutch, Brakes, Automobile, Machine Tools etc.
No, Carbon brush are made as per requirement of application, hence it is having different size, shapes, hardness, material quality and grades etc. So it is required selecting carbon brushes carefully according to requirement of application.
If carbon Brush material is not good then it will reduce life of moving part (commutator) as well as Carbon Brush.
