Slitting machines are key equipment in paper and packaging plants. They cut wide rolls of paper or film into many narrow strips. Keeping the material tension steady is very important. It makes sure the cuts are clean and the widths are exact. Old slitting machines often use magnetic particle clutches to control tension. These clutches work well for small tensions at slow speeds. But they cause problems at high speeds. The friction creates a lot of heat. This heat shortens the clutch life and limits how fast the machine can run.

• Tough Environment: The air is full of dust. Temperatures get hot. These conditions are hard on electrical parts.

• Need for Precision Control: Sometimes three motors work together on one machine. They must run at exactly the right speeds. If they don't, the cut material won't be straight or the same width.

How V&T Drives Help

1. They Handle Heavy Shocks: V&T drives manage the big load spikes during start, stop, and roll changes. They keep the machine running. Other drives often trip and cause shutdowns.

2. They Work in Tough Conditions: V&T drives are sealed against dust. Their cooling works well, even when it's hot. We know this works. These drives have run reliably in printing factories for 12 years. Dust and heat haven't caused major breakdowns.

3. They Control Speed Precisely: V&T drives control motor speed and power very accurately. When multiple motors need to work together smoothly, these drives make it happen. This keeps the material tension steady. The result? Material is cut cleanly and evenly, every time.

The Benefits

• More Machine Uptime: Fewer stops from load shocks or environment problems mean the machine runs longer.

• Better Quality Cuts: Precise speed and tension control ensure accurate sizes and clean edges.

• Built for the Job: These drives handle common pressroom dust and heat, lasting longer.

• Potential for Faster Speeds: They provide the stable power needed to try running slitters faster than older clutches allowed.
