[Ergonomic studies in a spinning mill--case study].

The effects of unfavorably assembled machinery on the workers was analyzed in a spinning-mill. Simple ergonomical methods were used such as: evaluation of the working process, of the movements, measurement of working heights, grasping space, dislocated weights, resistance to operating elements, length of lifting way. The workers were interrogated on their subjective feelings of tiredness and pains, their heart rate was measured. The physical strain and the ailments seem to be in connection with the cervicobrachial syndrome. Possibilities to introduce the proposed improvements were examined.
