<p>In a weaving machine (1), a control is kept, during ongoing weaving, of the thread tension (F), which is dependent upon position and/or rotation of one or more beams (7, 8, 9) forming part of the weaving machine. At least one beam (7) of the beams is suspended in a positionally mobile manner and is arranged so as to be detected by a force detection mechanism (13). The latter generates an electrical signal (il), the value, pulse number, etc. of which is dependent upon one or more forces, provoked by the thread tension, upon the beam(s). Each signal is utilised as a control signal in an activation system (14) effectuating the said thread tension control, which activation system incorporates a drive source (11) which operates with a feedback function and which preferably has the form of, or includes, an alternating-current servo motor.</p> |
