Definitions

  • the slitting group is normally constituted by one or more fixed knives, the blade of which is arranged in a plane parallel to the course of unwinding of the ribbon and perpendicular to its surface, while crossing this same course, the slitting being carried out quite simply by moving the ribbon itself.
  • the ribbons are separated immediately after being split by sending them alternately on two separate and divergent rewinding paths. Consequently, two independent coils must be provided, or two series of independent rewinding coils on two spindles with parallel but spaced axes.
  • the object of the present invention is to provide an improved slitting group, which can in particular make it possible to simplify the structure of the machine by making it possible to use a single group for rewinding and changing the spindles.
  • a rewinding machine comprising a roll of wide feed tape and a fixed slitting knife capable of separating said feed tape into at least two tapes of smaller width intended to be rewound
  • this result is obtained by the fact that downstream of the cutting position have been provided means for spacing the ribbons to be rewound which is followed in close proximity by a common guide roller.
  • said spacing means consist of a roller whose surface is formed by two truncated cones joined by their largest bases, the plane of union of said truncated cones coinciding with the plane axial of the cutting blade.
  • the adhesive tape 2 for supply unwinds from a reel 3 passes through a printing group 4, passes through the slitting group 5, object of the present invention, to get back then roll, in several separate ribbons, on a rewinding group 6.
  • the slitting group comprises, as can be clearly seen in Figures 2 and 3, two cylindrical guide rollers 30 and 31 between which the tape 2 completes a relatively short path.
  • the drawing represents an embodiment with a single knife which shares the ribbon supplying two ribbons to be rewound, but it is obvious that the slitting device may include any number of knives, naturally with the necessary structural modifications.
  • a second oscillating arm 35 on the free end of which is mounted an axis 36 for supporting a spacer roller 37.
  • the surface of the roller 37 is made up by two truncated cones joined by their largest bases, the line of union of these same largest bases being situated on a plane which coincides with that of the blade 32.
  • roller 37 Since the roller 37 bears with a slight pressure on the path of the ribbon between the rollers 30 and 31 - each of the two frustoconical surfaces providing support for one of the two slit ribbons - there is a slight effect d 'spacing of the same two split ribbons. The latter therefore come into contact with the surface of the guide roller 31 - arranged after and in the immediate vicinity of the roller 37 - separated from each other by a small space, for example some tenths of a millimeter.
  • roller 38 simply exercises an additional guiding function, without determining any spacing effect. In fact, if the spacer roller 37 is removed, the slit ribbons immediately approach and glue together in the path between the roller 31 and the rewinding reels, despite the presence of the ring spacer 39 of the roller 38 between these same ribbons.
  • FIG. 3 shows that the extent of the frustoconical surfaces of the roller 37 in the axial direction corresponds substantially to the width of a slit ribbon.
