CARDING
CYLINDER, TYPES AND FEATURES, SPECIFICATIONS
What is cylinders?
The Carding cylinder is usually manufacturer form cost iron, but is now some
time made of steel, most cylinder have a diameter of 1280-1300mm and rotate at
speed between 250-500 rpm.
Specifications
Diameter : 50 (120mm)
Speed : 250 – 500 rpm
Surface speed : 500 – 650
Wire point per inch :
Total wire point : 30lac
Fire point direction : Anti clock wise
Objective of cylinder
1. Back plate
To hold the fiber
To prevent the development of undesirable air current.
2. Top feather edge sheet
It control the weight & thickness of the flat strips
3. Cylinder stripping door
This door is used to strip the wire point of cylinder
4. Bottom sheet
To hold the fiber
To prevent the development of undesirable air current
5. Cylinder under casing
Remove dust
To maintain constant airflow
Types of cylinder
1. Single cylinder
2. Double cylinder
2. Single cylinder carding machine
Specifications
Cylinder diameter : 700mm
Output : 100-120 kg/h
Power : 18.5kw
Application
This machine can open various baled fiber and send to next procedure via fan.
It open fiber with pin plate high production and good quality.
A brief features of single cylinder
1. Single cylinder carding machine up to 1.5 m in diameter and up to 2.5 m
in width are produce as normal standard.
2. Cover all type of fibers from very fine too very course fiber dinner fiber
length up to 120 mm can be processed both synthetic and natural fibre of
all types can be processed.
3. Cylinder up to 1.5 m in diameter and up to 2.5 m in width are produce as
normal standard caring machine outside this size range can be discussed
dependent on card most main cylinder are balance to a surface speed of
1500 meters per minute.
4. All type of carding machine both single and double duper can be fitted
with randomizer roller or not dependent on customer needs.
5. Card wire can be supplied as surface wound or interlocking as required.
6. Card capacity is depending upon cot type fibre dinner type of fibre but
can be excess of 800 kgs per hour.
7. Other detail and variables dependent on customer needs can be discuss.
3. Double cylinder carding machine
Specifications
Middle cylinder diameter : 800mm,635mm
Big cylinder diameter :1230mm,1020mm
Power : 35kw
Application
Double doffer used for carding & mixing opened chemical fiber and blending
material.
Various kinds of fiber such as polyester, viscose, nylon, pp, fiberglass etc.
Cylinder speed
Higher cylinder speed helps fiber transfer. Higher the Production higher should
be the cylinder speed.
Higher cylinder speed improve carding action, thererby imperfections are
reduced.
Action between T-in and Cylinder
The Mtl get stripping action
The Mtl is also drafted here
4. Individualization of fibers is also achieved
Action between Cylinder – Flats
The Mtl get carding action
Max individualization of fiber is achieve in the region
Removal of Neps, short fibers, dirt and dust
Action between cylinder and doffer
Transfer of fiber from cylinder to doffer
Condensation of fiber takes place in between the doffer and cylinder
The Mtl gets doffing action.
