Definitions

  • the present description refers to a reel made entirely of cardboard or paper, for winding a flexible linear material such as fibers, yarns, fabrics, cords, tubes, among others. It also concerns a machine for producing the respective cardboard or paper reel and production method.
  • the reels comprise a tubular body where the flexible linear material will wind, and two flanges to prevent the flexible linear material from axially shifting off the tubular body.
  • Each of the flanges are arranged on each of the ends of the respective tubular body.
  • Document EP2205515B1 describes a collapsible reel or spool.
  • the collapsible reel comprises a core, around which a flexible material is wound, and flanges.
  • the core is formed by a first and second pieces that, before assembly have hub portions and a plurality of spaced tabs that project from the hub portions.
  • To form the core the tabs of each piece are folded and the tabs of the first blank are secured to the corresponding tabs of the second blank.
  • the flanges are then adhered to the outer surface of the hub portions.
  • Document CN107709204 describes a reel made of cardboard.
  • the body of the reel is composed of a plurality of parts that extend in radial directions that, when folded form the body.
  • the parts of the body comprise locking sections that are inserted into flange openings and bent to fix the body to the flanges.
  • None of the identified solutions present a solution composed only of paper or cardboard and that is easy to assemble.
  • the present description refers to a reel to receive a flexible linear material which comprises:
  • the first flange and the second flange can also be named first disc or second disc, respectively.
  • tubular body and the first and second flange are of the same material.
  • tubular body and the first and second flanges are made of paper or cardboard.
  • the reel (or spool) is made of a single material, preferably a biodegradable material. Preferably it is obtained in a single step, without being necessary any plastic element or other material required to join the flanges to the tubular body. Surprisingly, the tubular body is deformed to secure the flanges and mount the reel, thus avoiding the use of adhesives or other materials to join the different parts of the reel.
  • the reel has good resistance and durability, and can receive any type of winded flexible linear material.
  • the ends of the tubular body are projected outwards in a ring shape.
  • the tubular body has a thickness of 1 to 20 mm, preferably 1.5 to 15 mm, more preferably 2 to 5 mm, more preferably 2.5 to 3 mm.
  • the tubular body is a tube with a circular cross section.
  • the circular cross section has a diameter between 10 and 50 mm, preferably between 20 to 30 mm, more preferably 25 mm.
  • the first and second flanges have a thickness of 1.5 to 20 mm, preferably 2 to 10 mm, more preferably, more preferably from 2.5 to 5 mm, even more preferably 3 mm.
  • the central opening of the flange is circular.
  • the present description also concerns a machine for producing the reel which comprises:
  • the circular recess has a triangular shaped cross section ended in a rounded shape.
  • the machine comprises a first actuator to move the first riveting matrix and/or the second riveting matrix.
  • the machine comprises a second actuator to rotate the first riveting matrix and/or the second riveting matrix.
  • the machine comprises a motor to rotate the first riveting matrix and/or the second riveting matrix.
  • the support comprises an upper support and a bottom support configured to receive the tubular body between them.
  • the upper support is movable between an opening position and a closing position.
  • the first riveting matrix and the second riveting matrix are movable between a stationary or resting position and a riveting position.
  • the matrix comprises along an external surface a plurality of protrusions to dissipate the heat resulting from riveting.
  • the first actuator and the second actuator are motors.
  • the matrix comprises a detector for detecting the length of the tubular body.
  • the machine comprises a plurality of elements for the displacement of the matrix, in particular the elements are a plurality of wheels or casters.
  • the present description further describes a method of obtaining the reel described, which comprises the following steps:
  • the present description refers to a reel (or spool) for flexible linear material, a machine to produce reels and to its respective production method.
  • the reel has a high resistance and durability, being able to receive any type of winded flexible linear material.
  • the flexible linear material is a yarn, cord, rope, fibers, textiles, among others.
  • the present description refers to a reel to receive a flexible linear material which comprises:
  • the material of the reel is paper or cardboard.
  • the ends of the tubular body when riveting, form a rim on the outer surface of the flanges, particularly in the circular central opening of the flanges, to fix the flanges and thus prevent the axial displacement of the flexible material along the tubular body.
  • the tubular body and the first and second flange are of the same material.
  • they are selected between paper or cardboard.
  • the paper shall have a grammage of 5 to 300 g/m 2 , preferably 5.5 to 200 g/m 2 ; preferably from 6.5 to 160 g/m 2 , more preferably from 20 to 110 g/m 2 , more preferably from 80 to 105 g/m 2 .
  • the surface of the tubular body has a thickness of 1 to 20 mm, preferably from 1.5 to 15 mm, more preferably from 2 to 5 mm, more preferably 2.5 to 3 mm.
  • the tubular body is a tube with a circular cross section.
  • the first and second flanges have a thickness of 1.5 to 20 mm, preferably 2 to 10 mm, more preferably, more preferably from 2.5 to 5 mm, even more preferably 3 mm.
  • the diameter of the flanges is from 20 to 300mm, preferably between 50 to 200 mm, preferably between 70 to 100 mm.
  • the machine for producing the reel comprises:
  • Figure 1 represents the reel of paper or cardboard.
  • Figure 16 represents the machine, more specifically the removal step of the reel from the machine.
  • the final step is visible, the upper support is in the opening position and the matrix is in the initial position, in the resting or stationary position.
  • Figure 18 and Figure 19 represent section views of the machine.
  • the machine comprises a plurality of elements to move the matrix, in particular the elements are a plurality of wheels or casters.
  • the method of producing the reel comprises the following steps:
