LZ-8400 7G/10G · Glove overlocking

Published specifications

Values below come from the maintained catalogue record. The guide review date does not renew an earlier specification: read the dated source notes and confirm a current, matched configuration before comparing products.

Swipe the table sideways to see every column.

Both the catalogue title and the illustrated sheet name this machine as the 7G/10G ordinary version. Lizhu also sells an ordinary 13G/15G build, a 7G/10G double-layer or thickened label build, a 13G/15G/18G label build and several label versions for particular materials. All of them carry the LZ-8400 name.

Write the complete version title into your enquiry and onto the order. If one supplier quotes plain LZ-8400, ask which version the price covers before you set it against another offer. The Lizhu maker page shows the whole family. [1] [2] [3]

These values come from Lizhu's illustrated sheet for the ordinary 7G/10G version, which matches the web entry. The right-hand column gives the follow-up question for each one. [1] [2]

• For labelled cuffs, ask Lizhu to quote a label version as well as the ordinary build, then judge both on your samples.

The web table for the ordinary version includes a label-size row, up to 50 mm wide and 65 mm long. The illustrated sheet for the same version has no such row. Since Lizhu also offers dedicated label builds, the label row may belong to another version.

If your gloves carry labels, send Lizhu the label together with the glove and ask which version it recommends and what label tooling comes with it. Get a written answer on whether the ordinary 7G/10G machine handles labels at all, and see a labelled sample sewn on the machine you are buying. [1] [2] [3]

Choose 7G and 10G gloves in the yarns and sizes you actually sell, including any thick or unusual cuff. Gauge alone will not tell you how a given cuff behaves, so a trial on your own gloves is the fair test. Let Lizhu pick and record the setup for those gloves.

1. Describe the glove

   Note the gauge, yarn, number of cuff layers, cuff size, the hem you need and a reference glove you both sign. Mark labelled styles separately.

2. Agree the pass marks

   Decide how you will judge edge coverage, seam gaps, puckering, loose ends, and how far the finished cuff opens and stretches. Fix the measuring method first.

3. Watch the setup

   Note the version, guides, fixtures, thread and settings Lizhu uses. Watch how the operator loads, presents and unloads each glove and how long a size change takes.

4. Count on one basis

   Log run time, operators, actual rpm, stops, rejects and rework. Write down whether you counted single gloves or pairs and use that unit for every quote.

5. Lock in the result

   Keep the passed gloves and settings, note any faults, and check that the tooling and training delivered can repeat the result. Test again if the yarn or cuff changes.

Running the motor at 4,500–5,000 rpm is one thing. Producing 60 dozens of passed gloves in an hour is another, and Lizhu publishes no test method behind the figure. Time a run on your agreed gloves with normal loading and inspection, and plan from that count.

The 13G/15G/18G label version lists 50 dozens/hour and its own weights and packing size. That gap reflects a different job, finer gauge plus a label, so it says little about which machine is faster on the same glove. Compare outputs only for matching gauge, cuff build, label need and quality marks.

For mixed orders, add size changes, yarn changes and setup time to the plan. Count rejected and reworked cuffs on their own line. Ask how many operators the quoted output assumes, since the sheet describes an operator-fed machine and says nothing about unattended running. [1] [2] [4]

Ask for an itemised list for the ordinary 7G/10G build: guides and fixtures, controls, table, consumables and first spares. Some brochure photos show more than one machine, so state the quantity on the order and attach the equipment list.

Have Lizhu confirm voltage and phase, the full electrical load, air use and air quality, and send an installation layout with handling and safe-operation instructions. Decide who handles installation, commissioning and operator training. Plan the floor from the working area, not from the crate size.

Settle the price, delivery time, warranty, spare parts and support in writing. If your market needs model-specific conformity papers, ask Lizhu to name this version on them, because the CE wording on its company pages is general. Compare this build against other knitting and glove equipment before deciding. [1] [2] [3]
