Abstract: Method for manufacturing a hollow item made of glass, involving receiving a glass item associated with a moil (cap) at a temperature in excess of 100° C., setting the glass item in motion in a direction of conveying and in rotation on itself about an axis of the glass item, moving mobile equipment at a substantially constant distance from the glass item, identifying a relative position of the mobile equipment with respect to an edge of the glass item, regulating the distance between the mobile equipment and an edge of the glass item as the glass item is rotating and as the mobile equipment and the glass item are jointly moving along, firing a laser beam from optics supported by the mobile equipment toward said edge of the glass item in order to make holes and to part the glass item from the moil.
