Abstract

Procedure with its device for the continuous, mechanical and waste-free preparation of frusto-conical containers of heat-sealable material starting from a rectangular film, characterized by the fact that in the transverse strips of the aforesaid film pairs of trapezoids are combined that have in common , along the longitudinal central axis of the same, the minor base and alternatively the larger base, whereby two pairs of contiguous trapezoids will have in common also the four adjacent sides (in addition to a larger base and a base smaller than long of the central axis); then, the film is folded to reduce its width by half, therefore an initial central axis becomes a new external edge, while the original outer edges are placed one below the other; the film is cut longitudinally along the new outer edge coincident with the old longitudinal axis, only a series of overlapping trapezoids are soldered with a single weld and with a truncated cone welder and, simultaneously, pairs are cut along parallel sides of containers obtained with this welding and, at last, the two containers of the above-mentioned pairs are separated with single cut of large groups of pairs.
