Abstract : A circular loom which holds multiple longitudinal threads is able to weave them into a three-dimensional fabric using a filament insertion device which supplies it with multiple circumferential threads and a supply of weaver thread. One version of the filament insertion device uses two spools of circumferential thread which each have feed tubes and tension-meters which supply two lines of circumferential thread to a filament insertion device tip so that it may dispense two circumferential threads with adjustable tensions simultaneously to said circular loom. A weaver spool and weaver feed tube supply the filament insertion device tip with a tensionless supply of weaver thread so that it may dispense weaver thread when required. Patents. (jes)
