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: A measuring device which has a tape connected at one end to one end of a shaft and the tape is scrolled around the shaft. The visible surface of the tape includes a scale having a set of marks which defines a system of measuring units. The tape is inserted into a tube and allowed to spring open against the inner wall of the tube. A measurement can then be obtained for the internal circumference of the tube or the internal diameter of the tube.
