Abstract
An apparatus for use in determining the approximate web tension setting necessary for providing a predetermined web width in a machine, such as a web printer, which is used to process a continuous plastic web of the type which is subject to significant stretching and shrinking in response to relatively small web tension variations, comprising a first web restraining device for holdingly engaging a first end of a length of web material to be tested; a second web restraining device for holdingly engaging a second end of the length of web material to be tested; a force application device for applying a controlled amount of longitudinal stretching force to the length of web material to be tested; and a measuring device for measuring the width of the length of web material to be tested in a mid-region thereof during application of the longitudinal stretching force thereto. The apparatus may also be used for determining web graphics distortion.
