  • the conditioning of the roll paper causes that the cut sheets tend to roll up on themselves.
  • the phenomenon of winding, or "curl” is detrimental to the proper functioning of the processing devices using such packaging of the paper, and makes the subsequent manipulation of these sheets by the user not very easy.
  • the main problems posed by this phenomenon of natural winding of the sheets relate to the advance of the sheets and their stacking one on the other, avoiding possible jams.
  • the blade has a skew edge and is further mounted vertically movable in a guide, with the variation in diameter of the roller. It is carried by an articulated support having a terminal roller bearing on the periphery of the tape roll.
  • the blade is V-shaped and has against it a guide piece for guiding the strip.
  • This counter-piece has a concave face, V-shaped, on the inside of the strip, in which the blade bends the strip.
  • the object of the present invention is to avoid the above drawbacks by enabling quasi-flat sheets to be obtained.

  • the head 3 is mounted on a head support frame 11, with its control circuit 6 and its connector 5. It is applied against the drive roller 4 mounted on a machine frame 12.
  • the head support frame 11 is centered opposite the drive roller 4, around the shaft or mandrel 14 of this roller. The paper strip is thus held between the head and the drive roller which takes it from the roller as and when successive lines of information are printed.
  • the paper roll 2 is kept free to rotate in a tray 13.
  • This tray is simply formed by a substantially square profile on the machine frame 12. It retains the paper roll 2 held by the front flank of the tray.
  • This roller has a standardized band width, for example 210 or 216 mm. It is of given length, for example 100, 50 or 18 m. Its diameter is variable depending on the length of tape stored and as and when the tape samples.
  • this processing device is equipped with a leveling assembly.
  • the leveling assembly comprises a blade called bending blade 20 and a guide pin 30, which are mounted between the paper roll 2 and the drive roller 4 and receive against them the continuous strip 1.
  • the bending blade 20 is mounted on the side of the outside face of the strip coming from the paper roll 2.
  • the guide pin 30 is between the bending blade 20 and the paper roll, but receives against it the inside face of the strip from the paper roll.
  • the bending blade 20 has an edge 21, flat and substantially semi-circular and with a smooth surface. It comes to bear on the paper strip, to give the strip 1 an angle between 60 and 160 °, against its edge 21. The preferred value of this angle is of the order of 120 °.
  • its edge 21 has a radius of curvature less than 2 mm. It is preferably between 0.2 and 0.6 mm. A radius of curvature of 0.3, 0.4 or 0.5 mm is optimal.
  • This bending blade is metallic, for example aluminum, its edge has a perfectly smooth surface.
  • the guide axis 30, upstream of the bending blade for the driven strip, ensures the almost constant maintenance of the angle made by the strip against the edge 21 of the bending blade 20, whatever the diameter of the paper roll 2.
  • This guide axis 30 is fixed, preferably being free to rotate on itself. It is mounted on the machine frame 12.
  • the bending blade 20 is mounted directly on the head support chassis 11, between two flanges 11A of this chassis.
  • the flanges 11A have, for mounting the bending blade, a T-shaped groove 11B open on the lower edge of each flange.
  • Each groove receives one of the ends of the edge of the bending blade, opposite the edge 21 and designated by the reference 22.
  • This edge 22 is, at least at its ends, T-shaped corresponding to each groove 11B.
  • the bending blade also has two opposite shoulders 23, parallel to the branches of its T-shaped edge 22, serving as stops under the lower edge of each flange 11A.
  • the ends of the bending blade 20 are fixed on the flanges, so that the blade is positioned precisely against the strip of paper and that its edge 21 gives the angle defined above to the paper pressing against it.
  • the leveling assembly forces the strip to bend in the opposite direction from its natural winding direction, which its packaging in rolls gives it, to counter and cancel this natural winding.
  • the effectiveness of the leveling assembly depends on the radius of curvature of the edge, the positioning of the bending blade which gives the aforementioned angle to the paper, and the tension of the paper, for a given type of paper.
  • This leveling assembly is particularly satisfactory in operation for paper rolls of relatively small length, such as those of 18 m.
  • the bending blade 20 is given a prestress. Its edge 21, seen along its length, has an arrow corresponding to the action of a force F transverse to the bending blade received in its middle or to an initial shape which has been given to it. Its lower edge 21A has a convex profile coming into pressure against the outer face of the paper strip 1. This convex profile prevents the strip from having against the edge 21 a greater angle in its middle than on its edges as well as a lower contact pressure in the middle than on its edges. The tension of the paper and this convex profile of the edge impose a comparable bending on the upstream guide axis 30, as illustrated; the guide axis 30 tends to have the same arrow as that of the edge 21.
  • the resulting leveling assembly is then made as effective in the middle of the paper strip only on its edges by a balanced distribution of the loads over the width of the strip. This is not strictly the case when the longitudinal profile of the bending blade is linear: the leveling assembly then ensured obtaining sheets with the edges slightly more unwound than the middle.
  • the strip coming from the leveling assembly has its middle part having a slight tendency to wind in the opposite direction to the initial natural winding direction, while the edges retain a slight tendency to wind in this initial natural direction.
  • the leveling assembly then gives resistance to the resulting sheets.
  • the bending blade 20 is resiliently mounted on its own support 25, independently of the print head 3 carried by the head support chassis 11.
  • a spring 26 ensures the maintenance of the bending blade 20 and gives it elasticity.
  • the bending blade 20 remains mounted with the print head 3 on the head support frame 11, as shown, or can be mounted on its independent support, without being given an elasticity, but it is the guide axis 30 which is resiliently mounted, by a spring 31, on the machine frame 12.
  • the leveling assembly according to the variants of FIGS. 3 and 4 is perfectly indicated when using large rolls of paper, such as those of 100 m of strip.
  • the step-by-step driving of the strip gives rise to variations in the speed of travel of the strip under the print head, which cause variations in the tension of the paper at the level of the leveling set, because of the inertia of the roller.
  • the elasticity given to the bending blade 20 or to the guide pin 30 then makes it possible, under these conditions, to reduce the acceleration of the strip at the level of the paper roll, therefore to reduce the influence of the inertia of the paper roll and therefore to minimize variations in web tension.
  • the bending blade 20 is mounted resiliently or not on its own support 25, but, moreover, is positioned in an adjustable manner opposite the outside face of the paper strip 1, by a motor 40.
  • the motor 40 drives the support 25 along associated slides, not shown, for raising and lowering the bending blade 20.
  • the control of the motor 40 is itself ensured by an electronic servo-control circuit 41.
  • This electronic servo circuit 41 is coupled to the drive roller 4 or to its control. It allows in particular to control the rise of the bending blade 20 when the device is in standby state, so that the blade does not mark the paper. It also makes it possible to control the descent of the blade against the paper, depending on the speed of this drive roller.
  • the leveling assembly with the descent of its blade controlled as a function of the speed of movement of the paper under the print head makes it possible to avoid variations in the tension of the paper at the level of the bending blade, caused by the inertia of the roll of paper.
  • the control of the motor 40 is, moreover, directly controlled by the diameter of the paper roll permanently detected.
  • a lever 42 freely resting on the periphery of the paper roll, and an angular sensor 43, associated with the lever, make it possible to detect at any time the diameter of the paper roll.
  • the sensor is coupled to the servo circuit 41 to adjust the positioning of the edge of the blade as a function of the measurement of this diameter.
  • the angle of the paper against the edge of the bending blade is made variable with the diameter of the paper roll.
  • the control of the motor 40 is furthermore controlled by the state of curvature of the successive sheets taken from the strip 1, which is detected.
  • the servo circuit 41 is coupled to sensors for measuring the distance between them and the strip, such as the three sensors 45, 46 and 47 shown. These sensors are mounted one after the other, downstream of the print head 3 and the drive roller 4, on the paper path, with a distance between the extreme sensors 45 and 47 remaining less the length of the leaves. Comparative detection of the individual measurements given by the sensors makes it possible to detect the radius of curvature of each sheet, in order to adjust accordingly the position of the bending blade 20 and therefore the angle which the strip makes against the edge of the blade of bending, to remove this detected radius of curvature.
  • This detection of the radius of curvature of the sheets indirectly takes into account the diameter of the paper roll which gave rise to it. In addition, it also takes into account the nature of the paper and its variations in behavior with the external conditions of humidity and temperature, in particular.
  • FIGS. 8 to 10 preferred embodiments of the treatment device have been illustrated, with compensation for variations in the initial curvature of the strip during its unwinding of the roll and / or correction of a residual curvature after leveling.

  • the bending blade remains identical with regard to its fundamental characteristic defined by its edge, but is mounted differently on the head support chassis 11, opposite the strip 1. It is therefore designated under the reference overall 20 ′, with its edge designated under the same reference 21 as above.
  • This bending blade 20 ′ is mounted free to rotate about an axis 50 carried by the head support frame 11.
  • This axis 50 is formed on a spacer support 11E at the end of the head support chassis 11. It crosses, in its middle, the upper part 26 of the blade 20 ′, opposite its edge 21.
  • This mounting method is simpler.
  • it above all makes the edge 21 free to rotate about this axis 50, as symbolized by the arrow 50A, by letting it orient itself, in response to a possible variation in tension that may present. between them the two longitudinal edges of the strip under its ends.
  • This degree of freedom of orientation of the edge makes it possible to at least partially compensate for a different strip tension along the edge.

These two cones 52 are biased towards each other to hold the roller 2 between them, while leaving it to rotate.
  • two pressing members 52 such as two cones or two stepped cylinders
  • the two cones are urged towards each other to exert a constant braking torque on the mandrel 2A of the roller 2. They are carried by two spring blades 53 mounted in the machine frame 12, which allow setting in easy place of the roller, by a simple spacing by hand of these blades.
  • two spring blades 53 mounted in the machine frame 12, which allow setting in easy place of the roller, by a simple spacing by hand of these blades.
  • only one of these spring blades is elastic and the other is rigid.
  • the constant braking torque generates a tensile force on the strip strand up to the edge 21 of the blade 20 ′ which is increasing, as the diameter of the roller decreases and therefore that the curvature of the rolled strip increases.
  • This increase in strip tension under the edge 21 with the decrease in the roll diameter allows at least partial compensation for the initial variation in curvature of the strip with the roll diameter, accentuating the correction carried out as the initial curvature increases.
  • the device can also comprise a detector 55 for the state of curvature of the sheets delivered.
  • This detector 55 is shown in dotted lines because it is optionally used, in the preferred embodiments described below, to control a correction of detected residual curvature.
  • the detector 55 is advantageously constituted by a photoelectric source of transmission / reception, with transmitting cell 55A and receiving cell 55B.

  • the paper roll 2 is always mounted between two pressing cones or the like, partially engaged in the mandrel 2A of the roller, but one of the cones denoted 52A is fixed, while the other denoted 52B and said cone mobile is controlled in translation.

  • the stepper motor is a programmed command triggered by the operator, from a push button, for putting this movable cone in a retracted position for loading or unloading the roller and then in an initial position for retaining the roller. .
  • This programmed command is ensured by detection of a defined number of motor steps from the retracted position, to which corresponds a defined minimum braking torque exerted by the two cones on the roller 2 after its loading.
  • the rotation of the stepping motor is controlled in number of steps and in direction, from the detector 55.
