Description

The PRV-BT-V-500 Vertical Back Twist Buncher is a specialized solution for producing high-quality back twisted pairs, primarily used in LAN cables and data transmission lines. Vertical Back Twist Buncher Equipped with dual bobbin operation, a stable tension control system, and an integrated take-up unit, this machine ensures exceptional control over twist uniformity and wire tension.

The 90% stepless adjustable back twist ratio, 3.7kW main motor, and precision tension wheel system make it ideal for tight-pitch, consistent bunching. Its in-line tension sensor works in tandem with the pay-off motor to guarantee consistent output even at high speeds.

With robust construction, smart automation, and a compact footprint, the PRV-BT-V-500 is a reliable workhorse for modern LAN cable production.

Key Features:

  • Vertical double bobbin configuration for efficient back twisting

  • Stepless back twist ratio adjustment (up to 90%)

  • In-line tension sensor ensures constant wire tension

  • Dual head back-twist tension stand with precision potentiometer

  • Compact footprint with integrated take-up and pay-off systems

  • Ideal for LAN, CAT5e, and CAT6 pair bunching applications
