RING FRAME
DescriptionSpecification
DRAFTING: Attenuate the roving until the required size is obtained.
TWISTING: Making the fiber to spiral around each other about a central axis and bind themselves together to get desired strength.
WINDING : Coiling the twisted yarn around the bobbin as rapidly delivered by the drafting rollers.
BUILDING : To achieve round bottom cop by using building mechanism in ring frame.

FANCY RING DOUBLUER
DescriptionSpecification
Fancy Yarns and their production There are many varieties of fancy yarns. These yarns are produced by applying 3 types of special motions to either middle or back roller of the fancy doubling machine. They are

  1. Cam motion
  2. Rack and Box motion

Ball disc motion: The Cam motion and Rack and box motion can be applied in two different ways. i.e. as an intermittent motion, to set the rollers intermittently from rest or as an accelerating motion to accelerate the roller speed, periodically when it is already moving. The ball disc motion can be used as an accelerating motion to the back line of rollers. But it can also be used as an intermittent motion to the second line of rollers.
