The document presents a study on beam dyeing machines, detailing their construction, working principles, and maintenance requirements. Beam dyeing is described as an economical method similar to package dyeing, utilizing a perforated beam for dyeing fabric in an open width. Maintenance guidelines emphasize regular cleaning, checking of components, and ensuring optimal operation to manage water and energy consumption.

3. Introduction
1. Beam dyeing is simply a much larger version of
package dyeing.
2. This method is similar to package dyeing but is
more economical.
3. Yarn is wound on to a perforated warp beam or
perforated cylinders

beam
3: Fabric
4: Sampling unit
5: Pressure gauge
6: Overflow expansion/add dye
vessel
7 Preparation tank
8 Heat exchanger
9: Centrifugal pump
10: Opening port with lid

5. Working Principle
1. The fabric or yarn in open width is rolled on to a
perforated beam.
2.The beam then subsequently inserted into a
dyeing vessel.
3.The machine is closed and pressurized.
4.The dye liquor is circulated in to out and out to in
directions , under pressure and temperature is
employed as per the process requirement.
5.The chemicals and auxiliary are injected as per
requirement of the process.

6. Maintenance
• Cleaning of the machine-Every batch unloaded
• Checking the water pipe-Everyday
• Checking the motor and electric connection-Weekly
• Checking the flow of water-Every hour
• Steam pressure regulator checking -Every hour
• centrifugal pump maintenance-Clean bearing,Check oil
drain plug,Lubricate the bearings
• Heat exchange-cleaning inner tubes and the outer side

7. Discussion
• Circulation of dye liquor through stationary beam of
fabric in open width.
• beam dyeing machines relatively consume more water
and energy both and increases cost of dyeings
• As the fabric is being dyed in open width, rope and
crease marks are not developed
