Raschel Knitting Machine: Width, Gauge and Guide Bars Compared
A raschel knitting machine is chosen on four numbers: working width, gauge, guide bar count and warp beam positions. Across the five raschel platforms we build, width runs from 3454 mm to 8636 mm and gauge from E18 to E32, and the table below puts all four numbers side by side so you can shortlist on specification.
The four numbers that fix a raschel knitting machine
Working width caps the fabric you can sell off the machine. Gauge sets how dense the loop structure can be. Guide bar count sets how much pattern you can build. Beam positions and flange diameter set how long you run before the machine stops for a beam change.
Controls, monitoring and drives improve how well you hit those four, but they cannot move them. A machine quoted at 3454 mm will not make a 5 m net, whatever the control system does.
Five raschel platforms compared on published specifications
| Platform | Working width | Gauge | Guide bar and needle bar setup | Beams and let-off |
|---|---|---|---|---|
| Raschel machine for elastic and 3D spacer fabric | Up to 8636 mm (340 in) | E28, E32 | Four ground guide bars; individual needle and tongue bars; stitch comb bar and knockover comb bar | Three positions standard for sectional beams with 32 in flange; optional four positions for 21 in or 30 in flange |
| Double Raschel platform | 3505 mm (138 in), 5334 mm (210 in) or 7112 mm (280 in) | E18, E22, E24 | Two needle bars with latch needle units; two knock-over comb bars; two movable stitch comb bars; seven bars available for spacer work | Electronically controlled yarn let-off; take-up by geared motor with four rollers |
| Double Jacquard warp knitting machine | 3454 mm (136 in) | E18, E22, E24, E28 | Six ground guide bars; piezo-jacquard guide bar with split execution; dual latch needle bars | Six 812 mm warp beams, free-standing frame |
| Double Jacquard Raschel RJPC 4/2F | 4318 mm (170 in) | E18, E24 | Electronic control over both ground and jacquard guide bars | Three electronically controlled let-off devices for the ground guide bars |
| Raschel Jacquard RJPC 4F | 6300 mm (248 in) | E18, E24 | Pattern Device EL with fully electronic guide bar control for ground and jacquard bars | Three electronically controlled let-off units with multi-speed control; custom creel built for jacquard feeding |
Read the table by column, not by row. If your fabric needs E28 or finer, three of the five platforms drop out at once. If you sell 3 m wide goods, the 8636 mm machine is capacity you will pay to own and never use.
Guide bar drives: where pattern capability lives
Bar count alone is a weak signal; what the bars can do matters more. On the Double Raschel platform the EN-drive powers seven electronic guide bar drives, and an optional EL-drive extends guide bar shog distance up to 150 mm. The Double Jacquard machine quotes the same 150 mm for its electronic guide bar drive. That distance is the practical ceiling on how far a lapping can travel, which decides whether an advanced pattern or a spacer channel is reachable at all.
The other number to ask about is the knock-over comb bar distance, adjustable between 2 mm and 12 mm on a central trick plate on both double needle bar platforms. It is what you move when you chase a thickness target on spacer fabric, and it is the setting most often left wherever the commissioning engineer put it.
Which raschel knitting machine, given what you sell
If you sell 3D spacer, elastic mesh or cushioned structures for sports, automotive interiors or medical use, then the elastic and spacer platform fits: four ground guide bars, individual needle and tongue bars, E28 or E32, and a width scaled to your finishing line. Our elastic raschel machine page covers that configuration.
If you sell pile, plush, tubular goods or spacer with tuned compression, then the double needle bar route applies, with seven bars available for spacer and the 2-12 mm comb bar window to hit thickness. That family has its own guide: double raschel knitting machine.
If you sell patterned jacquard goods such as curtains, bed linen, upholstery or lace-effect apparel panels, then the jacquard platforms apply, and the deciding numbers become gauge (E18 or E24 on RJPC machines, up to E28 on the double jacquard machine) and working width.
This conclusion does not hold in two cases. If your customer has already fixed a pattern needing a shog beyond the drive range you are quoted, the drive decides before the class does. And if you are extending an existing line, the beams and creels on your floor can outweigh the whole comparison; flange diameter in particular is not something you want to run in two sizes.
Still deciding between classes and not between configurations? Start with raschel machine selection by needle bars, guide bars and gauge, then come back to this table.
Site requirements buyers check last and should check first
The RJPC 4F specification sheet is unusually explicit about the room the machine goes into. It lists a speed-regulated drive with a 7.5 kW total load on a 380 V three-phase supply with a 10 percent tolerance. Working conditions are 25 °C with a 3 degree band, 65 percent humidity with a 10 percent band, and floor pressure of 2000 to 4000 kg per square metre.
Floor loading is the one that catches people. A mezzanine or thin slab that was fine for a weft knitting line is not automatically fine for a 6300 mm raschel, and finding out after the crate lands is expensive. Batching on that platform winds to a maximum diameter of 685 mm (27 in), which also sets how much clear floor you need at the take-up end for roll handling.
Control, monitoring and after-delivery support
Across these platforms the operator works from the GrandStar Command System, which handles recipe setup, guide bar coordination, yarn let-off speeds, pattern sequence and production diagnostics from one console. Quality monitoring combines Laserstop with a high definition camera unit, so a fault is caught and traceable instead of discovered at inspection. Take-up on the jacquard platforms uses four rollers with black grip tape driven by a geared motor, a detail that shows up later as even roll build and fewer edge problems in dyeing and coating.
Machines are CE certified and carry a one-year warranty. After-sales teams are on the ground in Turkey, India, Vietnam, Indonesia and the United States, and engineers visit every one to two months to keep settings aligned as yarn lots and product mixes shift. Replacement elements for these lines are listed on the group warp knitting spare parts pages.
What to send before you request a quotation
Send the finished fabric width you actually sell, the structure or a sample, your target gauge, the pattern shog you need, your floor loading in kg per square metre and your supply voltage. Those six items narrow five platforms to one or two in a single exchange through our contact page, and they are all things you already know.
Frequently Asked Questions
What working widths does a raschel knitting machine come in?
Across our platforms the published figures are 3454 mm (136 in) on the double jacquard model, then 3505, 4318, 5334, 6300 and 7112 mm, up to 8636 mm (340 in) on the elastic and 3D spacer model. Choose against the finished fabric you sell, not the largest number on offer.
What gauge should I order for spacer or jacquard fabric?
The elastic and 3D spacer platform is listed at E28 and E32. Double raschel is listed at E18, E22 and E24. The double jacquard model covers E18 to E28, while RJPC jacquard models are E18 and E24. Match it to the fabric density you already sell and confirm in writing.
How far can the guide bars move on a raschel machine?
The optional EL-drive on the double raschel platform extends shog distance up to 150 mm, and the double jacquard model quotes the same figure for its electronic drive. That is the practical limit on how far a lapping can travel, so it decides whether a pattern is reachable.
What floor and power requirements should I plan for?
The RJPC 4F sheet gives a 7.5 kW total load on a 380 V three-phase supply with 10 percent tolerance, a room at 25 degrees C and 65 percent humidity, and floor pressure of 2000 to 4000 kg per square metre. Check the slab before the crate ships.
What support comes with the machine after installation?
Installation and training are delivered through manuals, online video guidance and on-site sessions. Local after-sales teams work in Turkey, India, Vietnam, Indonesia and the United States, with engineer visits every one to two months. Each unit is CE certified with a one-year warranty.
