Windings, warp length:
mm / meter inch / yard
windings = warp length (m) x 2000 windings = warp length (yd) x 72
(Ul + UA)* (Ul + UA)**
warp length (m) = (Ul + UA)* x windings warp length (yd) = (Ul + UA)** x windings
2000 72
*m = meter yd = yard
*Ul = inner circumference in mm **UI = inner circumference in inch
*UA = outer circumference in mm **UA = outer circumference in inch
Actual windings
actual windings (UA actual ‑ Ul)* x full windings *Ul = inner circumference in mm
(UA full ‑ Ul)* *UA = outter circumference in mm
Maximum yarn feed ‑ FZ:
FZ (mm/Rack) = 3000 x Ul* x 480
nH x i
Explanation of symbols:
m = meter
2000 = refers to Ul/UA and conversion from meter to millimeter
Ul= inner circumference in millimeter
UA= outer circumference in millimeter
3000=max. speed of beam motor
480 = rack
nH = speed of main shaft reduction ratio of the beam motor: warp beam
72=refers to Ul/UA and conversion from yard to inch

Dear Author www.warpknitting4u.com !
I can not recollect, where I about it read.
Thanks for ur comment,however I don't really understand what u meant....pls let me know more detail.
Thanks a lot for your contribution. Your blog is really helpful for me. I'm newbie in the warp knitting industry and there is no training or learning materials provided for me from my boss. :(
Dear Auther you are providing realy useful informations for warknitting thanks for that
i have one request if can provide informations on the standerd set-up of the knitting elements
such as needle hieght we set it at zero degree that is required hieght from the needle bed.
but i want to knwow about the toung position how to determine the exact position, again i know the lower knock over to be set when the needle is in zero degree. but how to determine the exact position of the upper knck over
@deepak:
the basic setting of knitting elements (standard setting) for each type of warp knitting machine could be different,depend of its motion. The basic setting of warp knitting machine mention on working instruction of machine called gang table.
Does anyone can help me with the formula to find the gauge that was manufactured a sample?
