No apparatus has been developed to measure a weight of running materials such as fabrics, sheets and others in dyeing and finishing processes.
Recently, the author has realized this apparatus for practical use, named “automatic sheet weigher”. The outline of the apparatus is as follows. The apparatus is able :
1) to detect, indicate and record automatically and continuously the weight of running fabrics in dyeing and finishing processes.
2) to indicate and record directly the percentage of water content in running fabrics, by pre-fixing the dry weight of the fabrics and by measuring the weight of fabrics.
3) to indicate and record the uniformity of weight and water content in width direction.
This apparatus can be used in the field of paper, plastic, metal and other industry in which manufacturing processes are controlled automatically.
