Fixed knives used under the licker-in and waste zones to control fibre rejection timing, airflow behaviour, and waste separation in carding machines.
Select your machine model to jump to its details below.
Mote knives and suction hood knives are critical waste separation interfaces in the carding process. They govern the clean release of short fibres, neps, and contamination without disturbing the primary fibre stream. Proper execution ensures waste exits predictably while preserving sliver quality and downstream consistency.
These knives work at the boundary between wanted fibre and waste. The mote knife separates waste from the cylinder or doffer surface, while suction hood knives control extraction geometry under airflow. Both must maintain stable clearance and angle — variation causes either incomplete waste removal or good fibre loss.
When mote or suction knives degrade:
Knife performance is machine-specific. The same knife geometry behaves differently on different card models due to wire speed, suction pressure, and interface positioning. We supply based on:
If you are working from a drawing, we can execute it exactly. For behavior-critical applications, OEM specification remains the safest reference — deviations are supplied as customer-defined execution.
