  • the tension cam 116 is in fact configured to cooperate with the drive member 115 and pivot between a relaxation position ( Figure 13 ) and a tension position ( Figure 14 ) when the drive member 115 is moved in translation between the initial state and the final state.
  • the movement of the drive member 115 allows the movement of the cutting means 19 and the pivoting of the tension cam 116 concomitantly.
  • the drive member 115 passes from the initial state to the final state, it causes the movement of the cutting means 19 from the rest position and the cutting position, at the same time as the pivoting of the cam tension 116 between the relaxation position and the tension position for tensioning the strip 7.
  • the figures 15 and 16 illustrate a longitudinal extension 120 of the device 1 according to the present invention.
  • the device 1 comprises a profile 111 extending along the extension axis A and configured for gripping the device 1 by a user.
  • the extension 120 is configured to fit reversibly with an end portion 121 of the profile 111 allowing its extension.
  • the longitudinal extension 120 comprises a latching means 122 and the end portion of the profile 111 comprises a complementary latching means (not visible in the figures) configured for latching with the latching means 122 of extends it 120.
  • the longitudinal extension 120 also includes a means for adjusting its length by the user.
  • the longitudinal extension 120 comprises a first tubular part 123 and a second complementary tubular part 124 and configured for sliding in the first tubular part 123 so as to reach the desired length of the longitudinal extension 120.
  • a system of immobilization 125 is also designed to immobilize the sliding of the second tubular part 124 in the first tubular part 123, so as to fix the length of the longitudinal extension 120.
  • the operation of the present invention is explained.
  • the areas of the plasterboards to which the strip 7 is to be applied are coated.
  • a reel 6 of paper strip is inserted into the storage means 5 and the strip is unrolled until it is placed on the sheet 32 so as to pass between the rollers 30 and the humidifying means 24A and 24B and on the guides 31 as well as the movable guide 36.
  • the tank 18 is filled with water, through the plug 72. Once filled with water, the tank is clipped onto the casing 29.
  • the user also decides the position of the rollers 30 relative to the humidification means 24A and 24B according to the humidification needs of the strip 7 to be applied. Indeed, depending on the position of the rollers 30, the strip 7 will be more or less compressed against the humidification means 24A and 24B and therefore the strip will be more or less moistened.
  • These humidification requirements of band 7 may vary depending on the environmental conditions in which the room is located, for example the humidity level of the room or the temperature of the room.
  • a user takes the device 1 in hand by the first gripping element 2 and the second gripping element 4 in order to orient the removal means 13, for example, towards a wall 20 for which two plasterboards must be attached.
  • the user can decide to apply strip 7 from bottom to top or top to bottom. Indeed, two humidification means 24A and 24B being present on each end of the reservoir 19, the strip 7 will be permanently moistened.
  • the toothed wheels 14A and 14B will rotate around the axis of rotation corresponding to the pivot axis 15, in the counterclockwise direction until the wheels notched discs 14A and 14B abut, both against the wall 20 and against the ceiling 21.
  • the notched discs 14A and 14B abut both against the wall 20 and the ceiling 21, the entire length of the necessary strip at the joint of the two plasterboards is ensured.
  • the user can then activate the trigger 26 making it possible to move, in a translational movement, the cutting means 19 from the rest position to the cutting position.
  • the traction cable 22 moves the cutting means 19 from the rest position to the cutting position by the pulley system 23.
  • the movement of the cutting means 19 causes the movement of the means connection 34, for example a pin, connecting the blade support 46 to the movable guide 36 supporting the strip 7.
  • the movable guide 36 will slide in the groove 39 and therefore no longer support the strip 7, thus making it possible to tension the strip 7 so that the central blade 60 and the side blades 64A and 64B, or the sharpened end of the second and third parts 58A and 58B of the blade support 46, can easily cut the strip 7.
  • the cutting means 19 are returned to their rest position by a tension spring 77, also returning the movable guide 36 to its initial position of support and guide of the strip 7.
  • the user activates the actuation trigger 76 of the caster 16 allowing the deployment cable 52 connecting the actuation trigger 76 to the arm 17 and passing a system pulley 51 to move the caster 16 from a retracted position to an deployed position allowing the caster 16 to press on the strip 7, which thus takes the shape of the corner.
  • the caster 16 Once the caster 16 is no longer necessary, it can be returned to its retracted position by a tension spring.
