Abstract (en)
[origin: EP0722791A2] The lubricating appts. is intended for an expandable strip winder mandrel with an inner shaft carrying several expander segments mounted on wedge surfaces rising in the longitudinal direction of the shaft. All lubricating points (5) are centrally lubricated by means of a single or multi-part cartridge (6a, 6b, 6c) provided with a number of longitudinal bores corresponding to the number of lubricating points. Each longitudinal bore is connected to a central lubricant distributer (12) and to annular grooves (9) leading-via bores (11) - to the lubrication points.
