  • Page 12: Introduction

    Like all jacquards, Jacq3G enables individual control over each thread, yielding the equivalent of an unlimited number of "harnesses". The design possibilities are endless. The Jacq3G uses the same frame as the A-series loom and has most of the same weaving options. Page | 4...
  • Page 13 The tension device allows you to advance the warp without a brake pedal. This is the standard setup for the Jacq3G loom. You will find that you can weave with less warp tension with a weight control than with the conventional ratchet system.
  • Page 14 Lift system The Jacq3G loom can come with an E-Lift, or an A-Lift. The E-Lift is an electrical motor, which replaces treadles on your loom and allows the shafts to be lifted easily and smoothly by pressing a pedal.

  • Page 15: About This Manual

    It is extremely important that you read this manual thoroughly and familiarize yourself with all parts of this manual prior to weaving. Each section has important information about the operation of your Jacq3G that you should be aware of, in order to prevent damage to your equipment and provide for many years of production.

    Using the Jacq3G Loom Jacq3G Loom User’s Manual ROCEDURE ARPING Jacquard Heddles are not rigid. This equipment will not tolerate significant distortion in the line of the warp yarns through the loom. For best results it is recommended that warp ends, when under tension, go from the warp beam, through the heddles, and through the reed with as little lateral distortion as possible.

    CAUTION: The Jacq3G hook module has both pinch and electrical shock hazards. The pinch hazards include: bearing surfaces, between knives and module frame, and between cables and stationary frame. The electrical shock hazards are anywhere on the printed circuit board, at the solenoid connectors and at the power entry connection.
  • Page 161 Jacq3G Loom User’s Manual Troubleshooting Test #1: Observe the solenoid plunger without power to the loom. Tap on the plunger. Does it spring out quickly and easily? Does it stick in or move sluggishly? If it does not spring out easily, then you have a misalignment issue.

  • Page 162: Equipment Fixes

    Troubleshooting Jacq3G Loom User’s Manual Test #7: Observe the misbehaving hook in action. Is it frequently crossing over/under with a neighboring hook? Does it have abnormal movement side to side or front to back as it slides up and down through the guides? If so, it or possibly the adjacent hook is bad.
  • Page 163 Jacq3G Loom User’s Manual Troubleshooting Upper guide alignment: If the hooks show any forward or rearward lean, adjust hex nuts for the upper guide until the hooks are vertical. Loosen the outer hex nuts, then cycle hooks up & down with null picks.
