The Correct Lubrication of TEXTILE MACHINERY: PART TWO PREPARATION MACHINERY Available to Purchase

Drawing Frames, Combers and Roving Frames. Drawing Frames (Fig. 3) are simple in construction, yet they must be in good mechanical condition and carefully maintained in order to produce uniform, strong, high‐quality yarn. Roll bearings present an important lubrication problem. The weighting of the top rolls is distributed both to top‐roll and bottom‐roll bearings. Microscopic tenacious persistent films of lubricating oil must prevent metallic contact with the roll necks inorder to minimise friction, wear and power consumption. This must be accomplished with sparing application of correct oil if throw and spotting are to be prevented. It is the practice in some mills to use a fluid grease in order to minimise the possibility of oil creeping from the bearings and staining the slivers.
