Abstract: A method and apparatus for measuring the relaxed length of a moving web includes forming a plurality of detectable marks along the length of the web at a repeated length interval. First and second detectors positioned along the web path are separated by a known distance S. A first tensioning force is applied to the moving web, and a first tensioned repeat length of the web is measured by detecting a mark moving past the first detector and then detecting the next mark moving past the second detector. The time separating the detections is determined. A second tensioning force of a known proportional relationship with the first tensioning force is applied to the moving web. A second tensioned repeat length is measured. The speed of the moving web is measured, and a relaxed length is calculated from the first tensioned repeat length, the second tensioned repeat length, and the proportional relationship between the first and second tensioning forces.

Abstract: A measuring apparatus and method for measuring the length of elongated elastomeric articles, such as rubber hose, which has a slide table and one or two measuring wheels which contact the hose as it passes over the slide table. The wheels are connected to readout devices which visually display the measured length. The invention also comprises means for keeping the hose straight and means for controlling an arc effect in the hose as it is being measured. A method is described which explains a way to correct for stretch or shrinkage of the hose which tends to give false measurements. A method is offered on how to calibrate the apparatus.

Abstract: The invention provides a simple and efficient method and apparatus for carrying out a quantitative measurement of waviness in a sample of paper. This is done by stretching the paper sample to the point where all waviness is removed and measuring the elongation produced at that point. The observation of waviness and its removal is facilitated by illumination of the paper sample with low incidence light while the sample is being stretched.
