SGD2012 · Yarn winding

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.

Sanfang prints two package options for this rewinder. Each capacity belongs to one tube entry, so read across a row and keep that pair together when you write the enquiry.

Several things are left open: the units of each dimension, the tube bore and material, whether the diameter means the body or the flange, and whether the capacity counts yarn alone. Settle them on a tube drawing before the heavier package tempts you. A bigger package saves changeovers only when your feeder holds it and it unwinds cleanly to the end. [1]

Sanfang names rapier, water-jet and air-jet looms as the destination for these packages. Each type feeds weft in its own manner, so say which one you run and send the holder drawing from its feeder. A physical tube helps where you can spare one.

State the withdrawal direction, the working orientation, the yarn mass you expect to draw from each package and any limits in transport or storage. Describe the yarn by linear density, construction and finish.

Agree what a good package looks like on your yarn: shoulder build, firm edges, no loose coils and a clean surface. Keep one package that ran well on your looms as the reference for later deliveries. [1]

An individual brushless motor drives each spindle directly. According to Sanfang, the spindles ramp gently to the set speed and then hold the line speed constant. The traverse is computer controlled, finely adjustable and moved by a ball screw.

The listed line speed of less than 750 m/min is an upper bound for the machine. Your working speed depends on the yarn, the package quality you accept and what the loom needs, so fix it during a trial with your own yarn.

The YS6324 motor rated at 0.09 kW drives the traverse. No total machine load is printed. For energy comparisons, ask for the supply and phase, the total connected load and a metered reading taken while the trial runs. [1]

The SGD2012 is listed with an automatic stop when the yarn breaks and another when the package is full. Ask to see both on your yarn, run by the operating procedure that ships with the machine, and ask how the full-package point is sensed and set.

If package length or net weight is written into your contract, ask which device measures it and agree a cross-check with a separate scale or counter. The words full package on their own name no measuring method.

Find out which settings the controller saves and which are mechanical. Have the technician change the yarn or package, call back an approved recipe and wind again, then inspect that first package closely. [1]

No output or quality figures are published for the SGD2012. Build acceptance around a short programme that finishes on your own weaving floor. [1]

1. Choose one lot

   Use a single yarn lot for the whole test and note its count, structure, finish and incoming package.

2. Lock the drawing

   Sign off the A or B option, tube drawing, net mass, finished size and holder fit before winding starts.

3. Label every sample

   Mark each package with its spindle, speed, traverse and tension settings and any stops. Take packages from more than one spindle.

4. Inspect at the winder

   Measure mass and size against the agreed tolerances, and look at build, edges, handling and surface.

5. Weave from them

   Put packages on your looms at full, partly used and near-empty stages. Log stops, sloughing and damaged yarn.

6. Count good output

   Record accepted packages over a whole cycle, including doffing, stops and rework, and file the settings and samples.

The weight of 2,350 kg is printed for the 48-spindle build. A shorter machine keeps its end drives, controls and access space, so ask Sanfang for the length, weight and power of the exact configuration it quotes.

The table gives 15,600 long, 1,200 wide and 1,600 high, without a unit. Ask for a current installation and handling drawing that shows loading and doffing space, service clearance, floor needs and the power connection.

Write into the order the yarn for commissioning, operator training, upkeep of the traverse, a starter set of spare parts and the warranty period. Price is not published, and neither is a full utility schedule. [1]
