Flat knitting is a method for producing knitted fabrics in
which the work is turned periodically, i.e., the fabric is
worked with alternating sides facing the knitter. A "Flat"
or Vee Bed knitting machine consists of 2 flat needle
beds arranged in an upside-down "V" formation.
SHIMA SHEIKI
Features of flat:
Flat knitting machine has two stationary needle beds.
Latch needles are used.
Angular cams of a bi-directional cam system is used.
The cam system is attached to the underside of a carriage, which with its selected yarn carriers.
The carriage traverses in a reciprocating manner across the machine width.
There is a separate cam system for each needle bed.
The two cam systems are linked together by a bridge, which passes across from one needle bed to the other.
Normally machine gauge is 3 to 18 needles per inch and machine width up to 79 inches.

YARN FEEDING MECHANISM:
4 Parts are taking part in Yarn changing mechanism
• Feeder
• Solinoid
• Hook
• Spring
FEEDER:
YARN FEEDING MECHANISM:
Hook:
Hook is the parts through which comes in contact of feeder. This really works by spring & solenoid .
Solenoid:
Solenoid is the main things to give selection to the feeder. When solenoid gets magnetize then the spring goes up, hooks comes down & feeder gets the selection
Spring:
When spring get in upper position then the hook comes down & Feeder is selected

CAM OF TERROT FLEECE MACHINE
SPECIAL CARE FOR FLEECE
1. Polyester Floating problem
2. Brush pilling problem
3. Sinker and needle mark problem in case of Sueding and Brush .
POLYESTER FABRIC
1. Patta problem for different in Texturisation.
2. Tension adjust of all feeder.
3. Loop / Picking problem.
4. Sharp edge of Metal causes the floating of Filament 75D/72 F .
5. Same date polyester use at a time in a machine.
