Application of ergonomics principles of burdening of the worker in the process of clothes cutting.

In the technological procedure of clothes cutting, lifting, transferring and putting of textile bundles on the machine for laying of cutting layers are considered to be the most difficult physical tasks. Upon standing position of the worker, centre of the mass is relatively high and hydrostatic pressure of blood column is increased influencing relatively increased blood circulation at the end of extremities. High incidence of muscle-bone and other health problems occur although this job has been classified as an easy one according to the criteria of energy consumption. These are ever growing cause of degenerative diseases of the vertebral column, absence from the work and early invalidity. Distortion of vertebral column towards right and left as well as forward in cervical and lumbar part of the body have been investigated upon monitoring of the work, as well as rotation of dorsal part of the body on the workers in the technological process of clothes cutting. Corresponding mathematical formulation has been shown for this investigation. Size of the distortion and rotation angles were investigated on four workers who perform various technological clothes cutting operations on two variously formed working places. Based on the monitoring of the workers values of vertebral column during working time were established, and also maximum distortion and rotation angles at the beginning and at the end of carrying out of cutting technological procedure, were established.
