Applications

Rollring Traverse Units are essential for applications requiring linear reciprocating motion with adjustable speed and stroke length, and automatic reversal for consistent unidirectional shaft rotation. These units are widely used across various industries to ensure efficient winding of materials, including:

  • Delicate fiber optic wires
  • Heavy-gauge cables
  • Wires, ropes, flat materials, strips, straps, hoses, filaments, tapes, foils
  • Solid materials such as steel, aluminum, copper, rubber, plastic, and fibe

Key Features

  • Precision Speed Control : Easily adjustable linear speed for precise operations.
  • Variable Speed Control : Fine-tune linear speed with a simple lever for optimal performance.
  • Flexible Stroke Length : Adjustable stroke lengths cater to diverse applications.
  • Smooth Operation : Engineered for reliable performance on a plain, round, hardened shaft with a finely ground finish.
  • Automatic Reversal : Instantaneous and automated motion reversal for seamless operation.
  • Low Torque Requirement : Efficient operation with minimal torque needed.
  • Consistent Rotation : Ensures constant-speed rotation of the shaft in a single direction.
  • Automatic Speed Synchronization : Ideal for winding applications, synchronizing speed automatically between bobbin and traverse.

Side Thrust

This term refers to the maximum force that can be safely applied in a lateral direction. If this force exceeds the specified maximum value, the traverse unit may slip on the shaft.

Pitch

Pitch denotes the linear movement of the traverse unit per one full rotation of the shaft. The pitch reaches its maximum value at a dial setting of 10. For precise adjustments, shift the pointer lever along the dial. For optimal accuracy and performance, it is recommended to operate the traverse unit at a setting above 1 on the dial.

Maximum Pitch

The maximum pitch is the linear movement achieved per one full rotation of the shaft, typically set at a dial setting of 10.
