ABSTRACT:
An improved tension controller for a strand to achieve constant downstream tension regardless of tension variation in the upstream strand has a pair of tensioning plates (9, 10) between which the strand upstream (3), downstream (5) is compressed, generating frictional force for added tension. A selectable loading force is applied to the controller in the opposite direction to the movement of the strand. This loading force acts on a wedge between a movable tensioning plate and a fixed plate (9). The angle between the fixed plate (9) and the strand between the tensioning plates generates a compression force at a right angle toward the compressed strand for added tension. The incoming strand is deflected before it reaches its compressed stage between the tensioning plates. This strand deflection generates a force-component in the direction of the strand movement and reduces the loading force correspondingly. By proper selection of the wedge angle, the reduction of the loading force results in a reduction of the added tension by the same amount.
