This machine includes a flap and a cover having a plurality of opposite-facing pairs of matching shapes comprising grooves and ribs capable of interlocking with each other after the cover has been closed. A strip of material is unwound between the flap and the internal wall of the cover without lateral deformation and projects from the matching shapes. The shapes are directly designed or have an additional element for reducing the space between certain portions of ribs and grooves in order to allow and encourage the separation of a piece of strip of material when it is pulled by the user. |
