Analysis of Operator‘s Work on Conventional and Modern Machines in Mechanical Processing of Textiles

Abstract

Work and time study constitutes the basis for planning production, manufacturing costs and calculating real operator‘s wages. Direct indicators of properly exploited operator‘s working time are product quantities in a given time unit and defined final product quality. The paper presents a detailed analysis of the operator‘s work at workplaces on conventional and modem machines in mechanical processing of textiles. Systematic machine development has resulted in considerable changes in the character of operator‘s work. Certain operations that constituted small or insignificant part of the operator‘s work on conventional machines have turned out to occupy most of his time on modem ones, e.g. inspection and control of the machines. In most cases the operator deals with the machine only when and if it has not succeeded in performing an operation upon repeated tries. The more modem machine the content of inspection and control is higher. However, safe machine operation of high quality is still not possible without interference of an operator. Higher degree of automation asks for higher responsibility and sophisticated knowledge, such as ability to operate industrial computers and higher professional knowledge of technology.
