Abstract:
A method of rectifying cylindrical articles, each having an outside surface, by abrasive action of a working grind wheel on the outside surface of each article, for producing rectification dust; said articles being moved continuously in translation by the action of a driving grind wheel along the entire width of said working grind wheel along an alignment strip positioned between said working grind wheel and said driving grind wheel; said working and driving grind wheels being rotated in the same direction, which direction is such that the action of said working grind wheel on said articles acts downwards, the method being implemented in an open protection device with the rectification dust that is generated being sucked away; the method comprising:statically and dynamically confining the generated rectification dust very close to the surfaces of said working and driving grind wheels; entraining practically all of said generated dust as confined beside the working grind wheel and beside the driving grind wheel towards the bottom of said working grind wheel in a flow of gas set up by said working grind wheel rotating and by implementing forced suction; and taking away practically all of said generated, confined, and entrained dust via said forced suction.
