ABSTRACT OF THE DISCLOSURE A spool for winding thereon a flexible elongate material includes a hollow cylindrical body having an elongate radial opening defined axially in the annular peripheral wall of the spool body for providing a passage of a holding means for automatically holding a leading end of the elongate material on the spool body. A winding apparatus includes a pair of oppositely disposed first and second drive shafts for holding the spool therebetween. The holding means is associated with the first drive shaft and cooperative with the radial opening in the spool body in effecting the holding of the leading end. The holding means is either the pneumatic type or the mechanical type. The pneumatic holder means produces a negative pressure in the axial hole in the spool body to create a suction force acting around the radial opening in the spool body. Due to the negative pressure thus produced, the leading end of the elongate material is sucked toward the radial opening and then adhered to the annular wall of the spool body. The mechanical holding means includes a row of locking needles movably mounted in an end portion of the first drive shaft so as to selectively project outwardly beyond the annular wall through the radial opening of the spool body.
