Abstract
Abstract An apparatus for detecting and regulating tension in a textile rope being pulled in a path from a source through a tension adjusting means by an advancing means includes a beam pivotally mounted for angular movement about an axis transverse to the beam and a guide arrangement to direct the rope through the beam pivot axis. One guide of the arrangement is carried by the beam at a location downstream of the pivot axis, the other being located upstream of the pivot axis. Passing the rope through the axis nullifies the effect of changes in frictional properties of the rope on tension induced deflection of the beam. Means are provided for detecting the amount of said angular movement of the beam and transducing it into a signal to actuate a control means for operating the tension adjusting means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
An apparatus for detecting and regulating tension in a flexible elongate structure moving in a path from a source through a tension adjusting means and a first guide means to an advancing means for the structure, said apparatus comprising: a beam pivotally mounted at a location between its ends for angular movement about an axis transverse to said beam, said beam carrying a second guide means spaced from said location, said beam being located between and mechanically separate from said first guide means and said advancing means, said first and said second guide means directing said structure through said axis whereby the tension in said structure upstream of said second guide exerts no torque on said beam, means for detecting the amount of said angular movement and transducing said amount into a signal; and a control means for actuating said tension adjusting means, said signal being fed to said control means for actuation thereof.
Claim 2
Independent Claim
154 words
An apparatus for detecting and regulating tension in a flexible elongate structure moving in a path from a source through a tension adjusting means and a first guide means to an advancing means for the structure, said apparatus comprising: a beam pivotally mounted at a location between its ends for angular movement about an axis transverse to said beam, said beam carrying a second guide means spaced from said location, said beam being located between and mechanically separate from said first guide means and said advancing means, said first and said second guide means directing said structure through said axis whereby the tension in said structure upstream of said second guide exerts no torque on said beam, means for detecting the amount of said angular movement and transducing said amount into a signal; and a control means for actuating said tension adjusting means, said signal being fed to said control means for actuation thereof.
Claim 3
Dependent Claim
36 words
The apparatus as defined in claim 1, said second guide means being an eyelet having an opening through which said structure passes, said opening having a central axis in a plane perpendicular to said transverse axis.
Claim 4
Dependent Claim
17 words
The apparatus as defined in claim 1, including means for limiting said angular movement of the beam.
Claim 5
Dependent Claim
14 words
The apparatus as defined in claim 1, said flexible structure being a textile rope.
