  • the distance between the two projections 85 of the shoulder of the rear edge 54 of the shell 50 of the sliding element 48 is equal to the diameter of the shaft 88 of the rotating element 86.
  • the projections 85 make it possible to tow the sheet 106 rolled during the translation of the sliding element 48 towards the open position of the main housing 12 until the expulsion of the sheet 106 from the rolling device 10.
  • the diameter of the shoulder 83 of the rear edge 54 of the shell 50 of the sliding element 48 is equal to the diameter of the shaft 88 of the rotating element 86.
  • the sheet 106 rolled is directly pulled by the shoulder 83 during the translation of the sliding element 48.
  • the peripheral wall 84 of the shoulder is smooth and does not have projections 85.
  • the rotating element 86 includes an arrow 103 represented on the wheel 100 to indicate to the user the direction of rotation of the wheel 100.
  • the third receiving slot 94 of the rotating element 86 is aligned with the first and second receiving slots 24, 60 along the same plane vertical P.
  • the alignment of the three receiving slots 24, 60 and 94 is required to introduce the sheet 106 inside the rolling device 10.
  • the free end 66 of the elastic blade 64 of the shell 50 of the sliding element 48 is aligned with the chamfer 96 of the third receiving slot 94 of the rotating element 86 according to the same angular distance D, D1 relative to the vertical plane P.
  • This angle formed by the free end 66 and the chamfer 96 facilitates the folding of the sheet 106 during rolling.
  • the unrolled sheet 106 shown in Figure 6 extends between a first and a second end 108, 110 defining its length.
  • the interior partition 112 is configured to reinforce the rolled sheet 106 so as to limit its crushing and also to improve the filtering capacity of the rolled sheet 106.
  • the folded zone 114 rests against an internal section 116 of the rolled sheet 106.
  • the folded zone 114 is previously glued so that the folded zone 114 is fixed by gluing against the internal section 116 to maintain the sheet 106 in the rolled position.
  • the folded zone 114 called pre-glued of the sheet 106 includes a layer of glue deposited before rolling the sheet 106.
  • the third receiving slot 94 passes through radially and the support 30 of the main housing 12 has a continuous stopping surface 104.
  • the geometry of the support 30 of this embodiment is simplified due to the absence of retaining groove 32.
  • the third slot for receiving the rotating element extends only along a portion of the diameter of the shaft 88 of the rotating element 86 and includes the stopping surface 104.
  • the geometry of the support 30 of this embodiment is simplified due to the absence of retaining groove 32.
  • the main housing 12 After carrying out steps 1 and 2, the main housing 12 is in a closed position and the first and second receiving slots 24, 60 are aligned along the vertical plane P. Following step 3, the third slot of reception 94 is aligned with the first and second receiving slots 24, 60 of the rolling device 10.
  • the rotation of the wheel 100 is carried out until the second end 110 of the sheet 106 is inserted into the rolling device 10 then rotation of the wheel 100 by making at least one additional revolution to ensure complete rolling of the sheet 106 around the shaft 88 of the rotating element 86.
  • step 7A or 7B of rotating the wheel 100 of the rotating element 86 the third receiving slot 94 of the rotating element 86 drives the sheet 106 guided by the convex shape of the support 30 of the main housing 12 and held in support against the shaft 88 of the rotating element 86 by the free end 66 of the elastic blade 64 of the shell 50 of the sliding element 48.
  • step 8 of translation of the sliding element is carried out by the user by applying pressure to each of the two gripping zones 82 of the sliding element 48 while maintaining the main housing 12.
  • step 8 of translation of the sliding element 48 the shoulder 83 of the rear edge 54 of the shell 50 of the sliding element 48 tows the rolled sheet 106 until it is expelled from the rolling device 10 by the portion lower open 56 of the shell 50 of the sliding element 48.
  • step 6 of introducing the first end 108 of the sheet 106 is carried out as far as the holding groove 32 comprising the stopping surface 104. Consequently, at the beginning of step 7A or 7B of rotating the wheel 100 of the rotating element 86, the first end 108 of the sheet 106 is held in the holding groove 32 to form the folded area 114 of the rolled sheet 106.
  • step 6 of introducing the first end 108 of the sheet 106 is carried out up to the support 30 comprising the stopping surface 104.
  • the sheet 106 rolled according to this mode embodiment does not include a folded zone 114.
  • step 6 of introducing the first end 108 of the sheet 106 is carried out up to the third receiving slot 94 comprising the stopping surface 104.
  • the sheet 106 rolled according to this mode of embodiment does not include a folded zone 114 and the internal partition 112 extends only along a portion of the diameter of the cylinder of the rolled sheet 106.
  • a rolling device 10 in the form of a pocket device having a small footprint offers an alternative to manually rolling the sheet 106.
  • Such a device is configured for individual training of filters and making it possible to obtain filters for rolling cigarettes all having a similar geometry and more particularly a substantially identical diameter determined by the size of the diameter of the shaft 88 of the rotating element.
  • the presence of a third receiving slot 94 of the rotating element 86 firstly allows the driving of the sheet 106 during the rotation of the wheel 100 of the rotating element 86, but also the formation of the internal partition 112 which stiffens the structure of the rolled sheet 106 and which improves the filtering capacity of the rolled sheet 106 when used in a rolling cigarette.
