Needle Punch Nonwoven Machine and Line Planning
Dry-laid web preparation and mechanical bonding, selected around the finished fabric.
KSG's catalogue and flow charts show a dry-laid needle punch route: prepare staple fiber, form a card web, cross lap it, then consolidate the batt through needle looms. A loom specification alone is not enough to choose a line; the feedstock, upstream web, and finished-fabric requirements must be considered together.
A documented dry-laid needle punch route
The polyester-geotextile chart shows fiber preparation, carding, cross lapping, and three needle-punch positions before cutting and winding. This is a process example, not a universal capacity or width specification.
-
1
Fiber preparation
Scale hopper, cylinder opener, spray equipment, magnet duct, mixing tank, and fine opener are shown first.
-
2
Web and batt formation
A vertical hopper feeds carding, followed by cross lapping and web feeding.
-
3
Staged needle punching
Pre-needling is followed by second and third needle-punch positions.
-
4
Finishing
The chart shows an accumulator, then cross cutting and winding. A waste picker is labeled separately below the finished-product box.

What sits in a needle punch line
Opening and feeding prepare the fiber for carding. The card forms a web, and the cross lapper builds the layered batt before needle punching. KSG's geotextile flow chart then shows pre-needling and two further needle-punch stages, followed by an accumulator and cutting and winding.
That chart is a polyester-geotextile example, not the specification for every needle punch project. The opening equipment, loom arrangement, and finishing stages should be selected for the actual fiber and product.
Agree the connections between machines as carefully as the machines themselves: feed stability, web width, controls, transfer sections, and stop and restart behavior all belong in the line review.
Needle looms and the velour option
Needle punching mechanically entangles fibers. Needle selection, penetration, stroke settings, and material advance affect consolidation and should be established through product trials.
The catalogue lists a velour needle loom separately. If a structured surface is required, include a reference sample and ask which loom and upstream preparation are needed.
Drying or thermal bonding may be a separate finishing requirement. Do not assume that a mechanically bonded fabric and a heat-bonded fabric can be made with the same equipment or settings.
The questions buyers should resolve
State the target weight, thickness, width, strength, and surface finish for each product. An unqualified weight range or top speed is not a reliable basis for choosing the line.
Ask how output will be measured, on which fiber, and against which quality limits. Define the trial duration, sampling method, and acceptance criteria with the supplier.
For multiple products, discuss changeovers and wear parts. Ask which settings can change through controls and which require needles, clothing, tooling, or other mechanical changes.
Define the project boundary
KSG's materials cover individual machines and connected line layouts. Ask for the offered machine list, interface responsibilities, utility requirements, and installation scope in writing.
Commissioning, training, spare parts, and support terms need a project-specific agreement. A catalogue diagram is not a commitment to a start-up date or a finished-product performance level.
Send KSG your fiber information, product sample, target fabric properties, output needs, and site drawing. These give a practical basis for discussing a needle punch line and an agreed trial and acceptance plan.
