Picking up in a positive manner from a feeding hopper in individual sequence horizontally positioned tubes, feeding them by gravity and delivering them, always positively held, to an element that from the horizontal pick-up position inserts them positively in a vertical plane with their open ends upwards in clamping elements on a processing line along which, advancing in increments, they are filled and closed and sealed in a conventional manner along the end thereof. Thereafter, synchronized with the incremental advance along the processing line, the tubes thus filled and end sealed, are successively gripped by transfer elements that insert them in preassembled boxes having their introduction opening facing upwards, at a packaging station, and there the tubes are packed inside the appropriate boxes with the introduction opening of the box being then closed.

A method for processing and packaging in boxes squeezable preformed open-ended tubular containers for substantially viscous paste products, comprising the steps of: (a) feeding said containers successively in a horizontal position from a hopper along a transport path traversed by each of said containers in turn to a first transfer device located along said path; (b) positioning each of said containers vertically at said transfer device with the open end thereof facing upwardly; (c) inserting each of said containers vertically into a respective flexible gripping device with the open end of said containers facing upwardly; (d) advancing said gripping devices with said containers along said path in increments into registration with at least one filling station located along said path for injecting said paste in turn into each of said containers through the open ends thereof; (e) further advancing said gripping devices with said filled containers along said path in increments into registration with a folding and crimping station located along said path for closing and sealing in turn the open ends of said filled containers; (f) forming said boxes from packaging blanks and positioning in turn each box along said path with an introduction opening thereof facing upwardly; (g) advancing said sealed containers in increments along said path into registration with a second transfer device located along said path for inserting in turn each of said sealed containers into a respective box through the introduction opening thereof; and (h) closing in turn the respective introduction opening of each of said boxes after the insertion therein of a sealed container.
