When sourcing equipment for net production, a common question among manufacturers is: what are the different models of a knotless net machine available on the market? A knotless net machine-most commonly based on Raschel warp knitting technology-comes in several configurations differentiated by needle-bar design, working width, gauge (E-number), and intended application such as fishing nets, shade nets, or safety nets. Choosing the right model of knotless net machine is critical to matching your product specifications with production efficiency.
The most prevalent type is the Single Needle Bar Raschel knotless net machine (e.g., models SRCA-135, SRCA-180, SRCA-260). These are designed for standard flat knotless netting including fishing nets, aquaculture nets, and agricultural shade nets. They typically feature gauges from E6 to E14 (needles per inch), 2–6 guide bars, and working widths ranging from 135" to 340" (approx. 3.4m–8.6m). This model of knotless net machine runs at 200–530 RPM and is the go-to choice for most commercial net makers.
For more complex or reinforced net structures-such as bale net wraps, double-layer nets, or spacer-type meshes-the Double Needle Bar Raschel knotless net machine (e.g., DRCA series) is used. This variant has two needle beds and can accommodate more guide bars (up to 8–9), allowing for patterned or denser constructions not possible on single-bar machines. Although less common for basic fishing nets, this knotless net machine model is valuable for specialized agricultural and industrial applications.
Machines are also categorized by gauge: E6/E7 for coarse mesh (heavy fishing or cargo nets), E9/E12 for medium mesh (standard knotless fishing nets), and E14/E16 for fine mesh (insect nets or lightweight safety barriers). The working width model-135", 150", 180", 220", 260", or 340"-determines how many net panels can be produced side-by side or the maximum width of a single sheet. Wider models of knotless net machine naturally have larger footprints and higher main motor power (3kW–11kW).
Some suppliers also offer Tubular Net Models for packaging/fruit nets and Electronic Pattern-controlled Models for custom mesh designs. While tricot warp knitters exist, they are rarely used for heavy knotless netting and pale in comparison to Raschel-type knotless net machine models in terms of versatility and output.
In summary, the main models of knotless net machine you'll encounter are single needle bar Raschel machines (most common for fishing/aquaculture/shade nets), double needle bar Raschel machines (for reinforced or specialty nets), and width/gauge variants (E6–E16, 135"–340"). Always match the model's gauge and width to your target mesh size and yarn type to ensure optimal performance from your knotless net machine.
