  • the enclosure which encloses the rollers 2 comprises two sections 11, 12 forming an angle.
  • the feeder device 1 is articulated by the point 13 around a support 14 integral with the structure 15, so that an angular displacement in the exit zone 16 of the rollers is possible.
  • the first of the rollers 2 is gripped by two support fingers 17,18 which are articulated and allow the roll to exit when the feeder device 1 is in the low position.
  • the angular displacement of the feeder device 1 is carried out by means of the jack 19.
  • the arms the transport arms 3 comprise two bars 21,22 joined by a end at a revolving shaft 23 in the support structure 15.
