Tension measuring device and method for filamentary material

摘要

The tension of filamentary material under tension in a process can be measured with improved accuracy. The measurement is effected by the tension measuring device having an elongated, externally insulated housing which substantially surrounds and encompasses a solid, continuous beam cantilever-mounted coaxially with the housing. The beam extends beyond the housing through an opening at the other end of the housing from its mounting to an engagement means for the filamentary material. The beam has at its distal end within the housing two or more target means located in a relationship to each other along different axes in the same plane where the target means are in sensing engagement with a sensing means which extend into the housing from a point of attachment on the housing. The opening of the housing is substantially covered by a shield through which the beam passes and to which there is mounted a strand contacting means. The housing has a gas supply means supplying gas from a source into the housing to move freely and exit through the opening between the shield means and the housing. The sensing means are connected to a conducting means to convey signals to an indicating means. The method of measuring tension during the formation of a plurality of fibers involves forming fibers, gathering fibers on a gathering means which is the engaging means of the tension measuring device, and off-centered winding of the gathered strands.
