Main Components and Working Principle
Needle Bar System
The needle bar system is the heart of a tricot knitting machine. It consists of compound or bearded needles arranged in rows. The needles move vertically to form loops, with the sinkers controlling fabric tension throughout the knitting cycle.
Guide Bar System
Guide bars are crucial for yarn feeding. Modern tricot machines can have 2-4 guide bars, each serving specific functions:
– Ground fabric construction
– Pattern application
– Yarn tension control
– Fabric width adjustment
Fabric Formation Process
The knitting action involves a precise sequence:
1. Yarn feeding through guide bars
2. Loop formation by needles
3. Fabric take-down
4. Pattern formation
5. Edge finishing
