A method of forming a random fiber web using pneumatic fiber feeding system is disclosed. The method includes providing a plurality of moveable apparatuses including a lickerin and a feeder, the lickerin configured to remove a plurality of fibers from a fibrous mat delivered to adjacent the lickerin by the feeder. The method also includes doffing the plurality of fibers from the lickerin at a doffing location within the system. The method also includes communicating an air supply to entrain the plurality of fibers with the air supply after the doffing. The method also includes controlling the air supply within a flow path between the lickerin and a collector. The method also includes collecting the plurality of fibers from the air supply on a collector to form the random fiber web.

Methods apparatuses and systems of forming a random fiber web using pneumatic fiber feeding system are disclosed. In one embodiment, a method can optionally comprise: providing a plurality of moveable apparatuses including a lickerin and a feeder, the lickerin configured to remove a plurality of fibers from a fibrous mat delivered to adjacent the lickerin by the feeder; doffing the plurality of fibers from the lickerin at a doffing location within the system; communicating an air supply to entrain the plurality of fibers with the air supply after the doffing; and collecting the plurality of fibers from the air supply to form the random fiber web.

A card wire has consecutive teeth spaced apart in the longitudinal direction by a pitch. The teeth are bounded in the longitudinal direction by a tooth face on a first side and by a tooth back on a second side. Looking downwards in the height direction of the card wire, the tooth face and the tooth back of consecutive teeth merge in a tooth base and, looking upwards in the height direction, form a tooth tip. The tooth depth is defined by the greatest distance, in the height direction of the card wire, from the tooth tip to the tooth base. The ratio of pitch to tooth depth is less than 1.1. An interspace, measured at right angles to a tangent to an inflection point between tooth back and tooth base, between this inflection point and the opposite tooth face is greater than a quarter of the pitch.

Described is a carding machine designed preferably to operate in a system for producing padding, which has a particular variability in the type of air processing which may be performed by the machine on the fibres, together with a greater simplicity of management of the configuration of the machine compared with prior art systems.
