【発明の名称】たて糸の張力を制御する方法およびたて糸張力調節要素を有する織機
Document Type and Number:
Japanese Patent JP2902669
Kind Code:
B2
Abstract:
To operate the loom, one or more warp-tensioning elements is or are actuated by separate drives on an individual pick basis with free triggering and at loom speed. The warp tension can therefore be so modulated as to obviate deleterious tension peaks and warp breakages and overflow tensions. The loom has at least one servomotor. A servomotor, which is triggered by a control and adjustment circuit arrangement, drives the warp-tensioning element by way of a reduction transmission and transmission elements. The servomotor can be commutated preferably brushlessly and electronically and have a low mass inertia rotor and high-field-strength permanent magnets.
