A device and method for dispensing and measuring a plurality of strands from a single spool of stranded material is disclosed. The device is comprised of a mobile portion on which a plurality of pulleys is mounted. The mobile portion includes a frame mounted on an axle to which tires are attached so that the mobile portion may be wheeled about readily. A stationary portion includes a plurality of pulleys and a supply spool of wire. Stranded material from the supply spool is routed back and forth between the mobile portion and the stationary portion, over the pulleys attached to each, until the number of strands between the mobile portion and the stationary portion corresponds with the desired number. Next the mobile portion is displaced away from the stationary portion a distance equal to the length of strands desired. A distance measurement device is mounted on the mobile portion to aid the user in ascertaining the distance that the mobile portion has moved, thereby indicating the wire length. Another embodiment of the invention includes open-faced pulleys that facilitate more rapid routing of the wires over the pulleys during use thereof.

Machine as claimed in claim 6, further comprising a rolling surface defining, together with said first winding roller, said insertion path for said spindles. 8. Machine as claimed in claim 6, wherein said winding cradle comprises a second winding roller defining, together with said first winding roller, a nip through which said spindles pass during winding. 9. Machine as claimed in claim 6, wherein said at least one suction nozzle is mounted on a rotating unit rotating about the axis of said first winding roller, and further comprising a movement device for controlling movement of said rotating unit about said axis in synchronism with movement of said insertion device. 10. Machine as claimed in claim 9, wherein said movement device causes a first rotary movement of said at least one suction nozzle in the direction of feeding of the spindles along said insertion path so as to follow each of said spindles from an insertion position to an intermediate position along said insertion path, followed by a movement in an opposite direction so as to bring back said at least one suction nozzle from the intermediate position into the insertion position. 11. Machine as claimed in claim 9, wherein said movement device comprises a motor and a gear wheel transmission. 12. Machine as claimed in claim 9, wherein said movement device comprises a wheel mounted idle on a shaft perpendicular to the axis of rotation of said first winding roller and supported by said rotating unit, and means which oblige said wheel to roll on a surface not rotating with respect to the axis of rotation of said first winding roller and on an annular surface of said first winding roller, perpendicular to its axis of rotation. 13. Machine as claimed in claim 12, wherein said means which oblige said wheel to perform a rolling movement comprises a pressing element movable in a direction parallel to the axis of rotation of said first winding roller. 14. Machine as claimed in claim 13, wherein said pressing element defines said non-rotating surface. 15. Machine as claimed in claim 14, wherein said pressing element extends over a portion of a circumferential extension of said first winding roller. 16. Machine as claimed in claim 12, wherein said rotating unit is associated with resilient recall members. 17. Machine as claimed in claim 3, wherein said at least one suction nozzle is movable along said insertion path with an alternating movement between an initial position and an end position. 18. Machine as claimed in claim 3, wherein said at least one suction nozzle is formed by a fixed suction duct and by a movable obturator arranged between the fixed suction duct and the spindles, the obturator following said spindles along said at least one portion of the insertion path. 19. Machine as claimed in claim 18, wherein said fixed suction duct has a curved shape. 20. Machine as claimed in claim 18, wherein said obturator consists of a movable wall adjacent to said fixed suction duct and has an opening with dimensions smaller that said fixed suction duct. 21. Machine as claimed in claim 1, further comprising downstream of said winding cradle, an extractor for extracting the winding spindles from each roll formed in said winding cradle; and a recycling path for conveying said spindles back towards said insertion device. 22. A method for producing rolls of wound web material, without a winding core, comprising the steps of: winding with a surface winding action a portion of web material of predetermined length around a winding spindle for forming a roll; and extracting said winding spindle from said roll, characterized by: providing suction holes on said spindle; providing at least one suction means cooperating with said spindle so as to produce a vacuum inside said spindle;
