Abstract (en)
[origin: EP1880963A2] Thread-guide device (14) with modulated traversing with an individual thread-guide (12) with a back-and-forth movement fixed to a cord (15) open at the two ends and moved between two pulleys (16a,16b) in an alternating clockwise/anticlockwise movement, each activated with its own electric motor (17a,17b), both motors being piloted in frequency. The pulleys (16a,16b) are connected to springs (18a,18b) which pull the thread-guide (12) towards the centre of its run and which alternatingly accumulate and release energy with every run of the thread-guide.
