Definitions

  • the present invention refers to an apparatus for feeding a material in the form of a continuous web, in particular a continuous ply of paper, tissue paper or non-woven fabric, to one or more operating machines.
  • the present invention is apt for use in the field of paper industry and industrial machines for the production and treatment of paper, tissue paper and the like, or of non-woven fabric and other types of paper.
  • tissue paper to operating machines is carried out by means of at least a feeding apparatus able to unwind a web of paper material from suitable feeding reels disposed on a fitting support structure.
  • the feeding of the web of paper material is normally operated until the respective feeding reel runs out of the same web. Afterwards, the feeding of the web is interrupted to allow the junction thereof with a further web of paper material carried by a replacing reel.
  • the web which is reeling off is then brought in contact with an adhesive region of the replacing reel's web so as to join the two webs and to provide a continuity to the operation of paper material feeding.
  • the Applicant has observed that the known feeding apparatuses are not without drawbacks and can be improved under many aspects, mainly in relation to the continuity of automation of paper material feeding.
  • the Applicant has found that the apparatuses do not ensure a continuous feeding of said paper material, and require a periodical interruption of their operation to allow the union of the reeling off web with a new web to be fed.
  • the object of the present invention is therefore to provide an apparatus for feeding paper material in the form of a continuous web to one or more operating machines, said apparatus being able to overcome the drawbacks of the prior art.
  • a further object of the present invention is to provide an apparatus ensuring a continual feeding of paper material without any interruption.
  • Yet another object of the present invention is to automate the operations of joining the reeling off web to a replacing web.

  • the first shaped seat 6 is connected to the portion of housing 4b of support structure 4 via an actuator 6a, preferably of fluid-dynamic type, able to borne, at least partially, the load of a feeding reel 5.
  • the actuator 6a allows the positioning of the respective first shaped seat 6 by adapting the latter to the support pivot 5a of the feeding reel 5 according to a position lined up with a respective rounded edge 4f of recess 4c.
  • the second shaped seat 7 is connected to the portion of housing 4b of support structure 4 via an actuator 7a, preferably of fluid-dynamic type which allows the positioning of the respective second shaped seat 6 by adapting the latter to the support pivot 8a of the first feed replacing reel 8 according to a second position lined up with a respective rounded edge 4f of recess 4c.
  • the apparatus 1 further comprises driving means 9 operatively associated with the support structure 4 to drive into rotation at least the feeding reel 5 about a respective axis of rotation "X" coincident with the longitudinal axis of the relevant support pivot 5a.
  • the rotation of the feeding reel 5 causes the unreeling of the respective web 3a along a feeding path "P" defined by one or more rollers 10 operatively disposed in proximity of the rest base 4a of support structure 4.
