The document summarizes the features and operation of a winch dyeing machine. The winch dyeing machine uses a stationary dye liquor and moves fabric in rope form through the bath using a winch reel. Key features include operating at temperatures up to 98C, using high liquor ratios from 1:20 to 1:40, and processing 1 to 40 ropes of fabric at speeds up to 40m/min. The machine body and components are made of stainless steel for durability and corrosion resistance during dyeing.

2. • This machine is the oldest form of piece
dyeing machine, the construction is very simple , easy to operate
and having economical cost.
• In Winch Dyeing Machine the Substrate is moving but the Liquor is
in Stationary form, and we can only process over fabric in rope
form but in Jig Dyeing machine we can also process over fabric
into open width and in rope form.
• This machine is versatile machine and it can be used for those type
of fabric which can withstand Creasing specially for light weight
fabrics.
• In single machine we can use different Dyeing positions.

4. 1)The Winch Machine can operate at maximum temperature
between 95-98C.
2)Generally the liquor ratio is high (1:20-1:40)
3)This machine is used for the fabric in rope form with stationary
liquor and moving material.
4) A number of 1-40 endless loops of fabric of equal length , can
process.
5)Rope passes from the dye bath over two elevated reels ,the first
roller is free running and second is winch reel.
6)The winch reel controls the rate of movement of the fabric and
also the configuration of the rope in dye bath.
7)Winch reel can not grip the fabric positively but by the weight of
the wet fabric and the friction between the reel and fabric

5. 8)In these days the stainless with corrugated and broken surface for
increase frictional forces are used.
9)The maximum speed of fabric must be approximately 40m/min.
10) This method is suitable for all fabrics, expects those which tend
to originate permanent creases or which could easily distort under
the winch stretching action.
Features:
1)Water inlet and out let valve
2)Direct steam coil made of perforated pipe
3)Machine body made of SS sheets 304 quality
4)Complete nipple with electric motor standard company
5)Big Roller made of SS or pipe and small roller made of SS pipe
