Needling Machines TRIZ Cases

A circular conveyor with a radial slot unwinds fibrous webs onto a straight chute, preventing deformation from conical rollers during automatic supply.

Compressed air jets replace needling to create z-fibers in carbon fiber preforms, preventing breakage and preserving in-plane strength.

Pin tooling creates z-channels through fibrous preforms, reducing voids and enabling even matrix infiltration in ceramic composites.

Intermediate storage buffers material to resolve speed mismatches between continuous sheet formation and periodic needling cycles.

Segmenting water jets with movable blocking members creates discrete patterns in nonwovens without expensive supports.

A needle loom uses a tilted guide pot to house drive means within a sealed casing for elliptical needling motion.

Segmented conveyor belt with guide fingers prevents mechanical deformation of voluminous nonwoven webs during textile processing transport.
