Pirn winding machine for making large package to small package.
WORKING PRINCIPLE OF PIRN WINDING MACHINE
• In the weft winding machine, the Pirn is driven by a spindle.
In the weft winding process a parallel winding packages results.
• Also, instead of winding them back and forth, the weaver winds them a half-inch at a time.
• The pirn is mounted on the spindle driven by a mechanism that consists of gears and cam.
• The pirn rotates at a very high and constant speed.
• When the diameter of Pirn increases. The yarn winding tension increases up to a little extent due to the less amount of yarn on the Pirn.
• When it rotates, it drags the yarn and winds on it.
• In the pirn winding process parallel winding packages results.
• This package comprises one or more threads that are laid very nearly parallel to the layers already existing on the package.
• The yarn receives fro motion through the yarn traverse guide.
• This yarn guide performs the traversing motion of yarn.
• yarn traverse guide which makes nearly parallel coils of yarn on the Pirn
•Almost half-inch of pirn ( chasing length) gets wound at a time.
