Abstract (en)
A process for producing rolls or bobbins of film material by unwounding the film from a parent bobbin of industrial diameter, and winding the same on a support, comprises the steps of: winding said film on an expansion spindle, with the latter being in its open position, until a bobbin having the desired commercial diameter is obtained; closing said spindle and sliding the coreless bobbin formed in that way out of it. <IMAGE>
