Multiple yarn insertion device

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 tensionmeters 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.
