ABSTRACT:
A device is provided for packing in supple bags articles billed individually at a check-out desk of a self-service store. The device includes: two slightly inclined rods; a reserve of supple bags suspended vertically from said rods via handles; means for evacuating these bags once filled; wherein the terminal part of each of the suspension rods, towards the free end thereof, presents a surface state different from the preceding part of the rod and such that the coefficient of friction of this terminal part is greater than that of the preceding part of the rod, with the result that the resistance to slide of the handles on this terminal part of the rods becomes greater than the previous resistance to slide, thus allowing, by the force of retention thus employed, the rupture of the separable point of connection between the rear face of the evacuated filled bag and the front face of the following empty bag pulled towards its position for filling.
