1. The Original System: Ball Bearing Reciprocating Mechanism

This is a purely mechanical solution for oscillation, known as a "traverse mechanism."

How it Works:

A rotating cam or a "wobble plate" with a slanted face is connected to the main spindle.

A lever arm, equipped with ball bearings at its end, is pressed against this rotating cam.

As the cam rotates, the slanted face pushes the ball bearings side-to-side.

This converts the rotary motion of the spindle into a precise, repeating reciprocating (back-and-forth) motion of the lever.

The lever is directly connected to the "base seat" or guide that directs the steel strap back and forth across the coil.

Disadvantages (The problems you are solving):

Fixed Ratio: The oscillation rate is mechanically tied to the spindle speed. You cannot change the "winds per traverse" without physically changing gears or the cam.

Inflexible Pattern: The winding pattern (e.g., precise layering, step-over) is fixed and cannot be easily optimized for different strap widths or tensions.

Maintenance: Mechanical wear on the cam, lever, and bearings leads to increasing slack and loss of precision over time.

Shock and Vibration: The sudden reversal at the end of each traverse can cause jerks in the strap, especially with heavy steel.

2. The Improved System: Inverter Motor-Controlled Oscillating Rewinder

This is an electromechanical or mechatronic solution. It decouples the winding motion from the oscillating motion, allowing for independent and sophisticated control of each.

Here is a conceptual diagram illustrating the core components and control flow of this improved system:

As the diagram shows, the system's intelligence comes from the PLC, which independently controls the two motors based on sensor feedback. Let's look at the key components and their benefits:

Key Components:

Spindle Inverter & Motor: Controls the main rewinding torque and speed.

Oscillating Inverter & Motor: Replaces the cam and lever. This is likely a servo motor or a high-precision inverter-driven AC motor connected to a ball screw or a belt drive for linear motion.

Programmable Logic Controller (PLC): The brain. It runs a program that coordinates the two inverters.

Encoders/Position Sensors: Provide real-time feedback on the spindle's rotation and the oscillator's linear position to the PLC, enabling closed-loop control.

How It Works & Major Advantages:

Independent Control: The PLC can move the oscillator at any speed and pattern, completely independent of the spindle speed. This allows for perfect, gapless winding and optimized patterns.

Soft Reversals: The inverter can precisely control the oscillator motor to decelerate, stop, and accelerate smoothly at the ends of the traverse. This eliminates jerking, reduces stress on the strap, and minimizes machine vibration.

Digital Precision: The system can be programmed via an HMI (Human-Machine Interface) for different strap widths. The oscillator's travel distance and speed are set digitally, with no mechanical parts to change.

Advanced Patterns: You can implement sophisticated winding patterns like:

Precursive Wind: Slightly increasing the oscillation frequency as the coil diameter grows to maintain a tight pattern.

Step-Back Wind: Making small shifts at the coil edges to build a perfectly square, stable coil.

Tension Control Integration: The system can easily integrate with a tension measurement system (e.g., a load cell or dancer arm), allowing the PLC to dynamically adjust both winding torque and oscillation speed to maintain perfect, consistent tension from the core to the full coil.

Summary of the Improvement

You are moving from a mechanically linked, fixed-ratio system to a software-defined, flexible, and precise motion control system. This results in a superior quality coil, less wear and tear, greater operational flexibility, and likely higher production speeds for your steel strap rewinding application.
