紙管の製造における熟練者と非熟練者の違い

Abstract

Many kinds of paper tubes are used as core of toilet paper craft tapes, print paper and film etc. Paper tubes are also used for subsidiary material, display and packing part, a part of an exhibition stand and its structure. In 1950s, the paper tubes were firstly produced in Japan. From then on, the technical innovation for machine structure to produce paper tubes is rarely seen except the NC control. Paper tubes are usually produced by expert workers who are trained for experience. The manufacture technology can also be developed by this empirical rule. Paperboards for paper tubes production are not stable and the paper tubes fabrication is different with the mass-produced goods that are produced in a certain size and shape, it belongs to the class of high-mix low-volume production. Even many orders are received with a short delivery time, it is also a career that the technology is inherited in the daily working. The so-called expert is non-expert person who is trained in the daily working and improve the technology by himself. It is a task for middle and small-sized enterprises in how to train the workers in a short time effectively. This is not only for paper tubes production, but also for a small factory on how to inherit its technology in a short time effectively. The objective of this is to analyze the motion for paper tubes fabricating by observe difference between expert and non-expert at work site as one of “Great master's work” in middle and small-sized enterprises.
