Apparatus for measuring yarn tension

Apparatus for use on a weaving machine for weaving yarn into a fabric, the apparatus comprising a measurement unit including a signal transmitter and a force responsive surface operatively coupled with the transmitter for generating signals as a function of a force applied to the surface, a layer of an elastomeric material connected with the surface, and a yarn guiding member connected to a side of the layer opposite the surface for guiding the yarn past the measurement unit and arranged so that tension in the yarn generates a force which is applied to the surface via the yarn guidance member and the resilient layer, whereby the signal transmitter generates a signal indicative of the tension in the yarn.

A weaving machine for weaving yarn into a fabric, the weaving machine comprising a yarn guidance surface for guiding the yarn that is to be woven, a measurement unit including a signal transmitter and a force sensing surface, and a resilient member connected to the yarn guiding surface and the force sensing surface for transmitting a force generated by the yarn and applied against the yarn guidance surface to the force sensing surface, whereby the signal transmitter emits a signal responsive to the force applied to the force sensing surface and thereby a signal representative of the tension in the yarn engaging the yarn guidance surface.

Apparatus measuring yarn tension including at least one measurement unit having a signal transmitter, a yarn guidance member defining a surface for guiding the yarn, and a layer of an elastomeric material mounted on the signal transmitter and connected to the yarn guiding surface and directly transmitting forces resulting from the yarn tension from the yarn guiding surface to the signal transmitter.
