Definitions
- the invention relates to a method and a device for manufacturing cardboard angles provided with a coating.
- the invention also relates to the angles made according to the method and / or by means of the device according to the invention.
- angles To protect certain edges of angles, in particular in packages surrounded by strips, it is known to use angles.
- the inventor imagined an original structure.
- the inventor has devised a method of manufacturing such angles and has developed a device for its implementation.
- the method according to the invention for the manufacture of cardboard angles from at least one strip of cardboard and at least two strips of covering of another material is remarkable in that it consists in: a) bringing and gluing the cardboard strip (s) in superposition on a first covering strip which is wider than said strip of cardboard; b) fold the longitudinal edges of the covering strip until they come back, forming folds on the free face of the last superimposed cardboard strip; c) gluing a second covering strip of a width substantially equal to that of the cardboard strips on the folds of the first covering strip and the free face of the last superposed cardboard strip; d) fold the assembly thus formed longitudinally at right angles to form an angle.
- the strips are formed by a complex based on aluminum and / or polyethylene. To ensure better bonding in this case, the interior face of at least the second covering strip and / or the face of the cardboard strip to which it is applied is previously heated before being applied and glued by pressure.
- the longitudinal folding can be carried out either so that the second covering strip forms the inside surface of the angle iron, or in opposite directions so that the second covering strip forms the outside surface of the angle iron.
- the invention also relates to a device for implementing the method and which is remarkable in that it comprises a supply and gluing system in superposition of at least one strip of cardboard on a first strip of coating, a wrapper to fold the first coating strip, an applicator downstream of the wrapper to apply the second coating strip and a folder to fold the assembly longitudinally.
- applicator comprises a heating device and at least one pressure roller.
- the wrapper has two lateral wings each provided with an inward fold to form a passage so that the cross section of said passage is decreasing both in width and in height over at least part the length of said wrapper in the direction of travel of the strips.
- the wings of the wrapper are mounted so that their reciprocal spacing is adjustable, in order to be able to easily adapt said wrapper to the different strip widths.
- the invention also relates to corniè ⁇ res manufactured according to the method and / or by means of the above-mentioned device.
- an angle iron according to the invention is remarkable in that it comprises at least one strip of cardboard thus forming two sides of a complex which is caught between two covering strips, one of which, more as wide as the said cardboard strip (s), is glued to one side of the complex and folded over to the other side of the complex while the other covering strip, of a width equivalent to that of the strip (s) of cardboard, is applied to said other face of the complex and to the folds of the first covering strip.
- FIG. 1 schematically shows an overall view of a device according to the invention
- FIGS. 2 to 7 show in schematic transverse views the manufacturing phases according to lines II to VII of FIG. 1,
- FIGS. 8 and 9 respectively show in plan and at the end a wrapper according to the invention
- FIG. 10 and 11 show in perspective from two separate angles the wings of a wrapper according to the invention.
- Figures 2 to 7 show the manufacturing line of Figure 1 at various stages. It is clear that Figures 2 to 7 are not sections but representations of principle.
- a supply device (not shown) comprising for example several reels.
- the strips are brought to one another with the interposition of a layer of glue by means, for example, of glueers (not shown). If the figures show 3 strips of cardboard, there can of course be more, or less.
- the thicknesses shown are completely arbitrary.
- the three strips 1a to 1c arrive above a first covering strip 2a slightly wider than said cardboard strips and also covered on top with a layer of glue.
- the strip 2a is for example based on polyethylene and / or aluminum.
- This first manufacturing phase is shown diagrammatically in FIG. 2.
- the assembly formed by the covering strip 2a and by the cardboard strips 1a to 1c then enters a wrapper 3 (phase shown diagrammatically in FIG. 3).
- the wrapper 3 which will be described in more detail below, is intended to fold the edges of the strip 2a on the sides of the cardboard strips (FIG. 3) until it forms folds above the free face of the last strip of cardboard 1c (FIG. 4), the complex (1a, 1b, 1c, 2a) thus formed leaving the wrapper 3 as shown in FIG. 5.
- a second covering strip 2b of the same kind as the strip 2a but of a width similar to that of the cardboard strips 1a to 1c is brought as shown in FIGS. 1 to 5, downstream of 1 * enro ⁇ beuse 3 to be applied to the above complex.
- the bands 2a and 2b are shown in the drawings in solid lines.
- the folder B comprises two chains Ba, Bb each formed of a plurality of chevron-shaped links in FIG. 7, fitting into each other over a certain length so as to fold the complex (1a, 1b, 1c, 2a, 2b) longitudinally by enclosing it to form an angle 7 ( Figures 1 and 7).
- the wrapper 3 has two symmetrical lateral wings 3a, 3b ( Figures 8 * to 11), the spacing of which is preferably adjustable by means of, for example, knobs 8a, 8b ( Figures 1, 8 and 9) intended to actuate screws. spacing.
- the wings 8a, 8b of the wrapper 3 have inward folds and a particular shape as the perspectives of Figures 10 and 11 clearly show, such that the cross section of the passage thus created decreases in width and height over part of the length of said wrapper in the direction of travel of the strips. It is clear that the wrapper is provided as already explained for partially coating the cardboard strips with the strip 2a, by folding the edges of the latter.
- the angle 7 thus produced is particularly resistant and waterproof depending on the nature of the covering strips 2a, 2b.
- easy continuous manufacturing is possible with a device according to the invention.
