Peripheral rewinding machine for producing rolls of wound web material and corresponding method of winding

A method for producing rolls of web material, comprising:

• inserting a winding spindle into a winding area;
• winding a predetermined quantity of web material on said winding spindle to form a roll around said winding spindle;
• discharging said roll from said winding area;
• and thereafter extracting said winding spindle from the roll;
• wherein said spindle is present in two portions, said two portions are connected before introducing said spindle into said winding area, and the two portions of a spindle are extracted separately from opposite ends of the roll after the roll has been discharged from the winding area.

A peripheral rewinding machine for producing rolls of wound web material, comprising an insertion device for sequentially inserting winding spindles into a winding area;

• winding means in said winding area, which wind predetermined quantities of web material onto said spindles to form said rolls;
• downstream of said winding area, an extractor for extracting said spindles from the rolls of web material formed thereon;
• a recirculation path for returning the spindles extracted from said rolls toward said insertion device;
• wherein each of said spindles is present in two portions which can be connected and disconnected, said extractor extracts each of said two portions from a corresponding end of a corresponding wound roll, and means are provided for reconnecting said two portions to each other before said spindles are reinserted into said winding area, wherein said means for reconnecting the two portions of each spindle to each other comprise longitudinal guide members for the two portions to be connected and axial pushing members which push said two portions toward each other and wherein said axial pushing members comprise an intermediate rotating distributor on which said two portions are connected together, the distributor discharging the connected spindles toward the insertion device.
