MEASUREMENT APPARATUS FOR FOAMED AND CONTRACTED VOLUME OF FOAM MATERIAL AND THEIR MEATUREMENT METHODS

摘要

The present invention provides a device for measuring the foamed and contracted volume of a foam material comprising a lower plate; an upper plate arranged above the lower plate and having one end fixed on the lower plate; and a sensing device for measuring the deflection of the other end of the upper plate. The device is to measure the foamed or contracted volume of a foam material by measuring the displacement of the other end of the upper plate according to the foaming or contraction of the foam material when the foam material is attached to a predetermined section between the lower and upper plates Also, the present invention provides a method for measuring the foamed and contracted volume of a foam material comprising a step of attaching the foam material in the predetermined section between the lower plate and the upper plate arranged above the lower plate and having one end fixed on the lower plate; and a step of measuring the deflection of the other end of the upper plate according to the foaming or contraction of the foam material.
