After carding, the fibre web is very thin and narrow. A cross lapper takes that web and folds it back and forth to build a wide, thick and even batt — the foundation of a quality needle-punched fabric. This article explains how it works and what to watch when specifying one.
The lapper receives the carded web on a conveyor, then layers it cross-machine-direction (perpendicular to the line) to reach the target width and gram weight. Even laying is the single biggest factor in fabric uniformity. [Fill in: how Huakai lappers control draft and tension.]
Huakai offers feeding and cross-lapping models (e.g. YBG101–YBG104 for feeding, YBG301 for cross lapping) for different widths and capacities. [Fill in: which model suits which product — geotextile vs. filtration vs. automotive.]
High-speed lapping must keep layer alignment stable. Servo-controlled carriages reduce drift and improve edge-to-edge evenness. [Fill in: typical line speeds and width ranges.]
The lapper must match your carding output, final width and GSM. Tell us your specs and we size the feeding + cross-lapping combination. See our lapper models.
