Step 1: Comprehend the operational principle. The system consists of two plates: a stationary baseplate and a mobile weighing plate. Yarn passes between them. The weighing plate exerts force on the yarn, thus creating tension.
Step 2: Evaluate tensioner classifications.
- Multiplicative tensioner (disc tensioner): This type regulates tension by compressing the yarn between two surfaces (discs or plates). The tension is pressure-dependent. The described baseplate and weighing plate configuration aligns with this type. Tension is derived from incoming tension, modified by a factor influenced by friction and wrap angle.
- Additive tensioner: This type increases tension by altering the yarn path with weighted pulleys or arms.
- Electronic tensioner: This encompasses various mechanical designs, electronically controlled for constant tension.
- Roller tensioner: This uses rollers to control tension, often through specific yarn paths or roller braking.
The described plate system exemplifies a multiplicative or disc-type tensioner design.
