Abstract: Strips containers are formed using two continuous webs in thermoformable and heat-sealable material facing each other. The webs are indexed along a feed line through different operating stations that transform the webs into a continuous strip of containers, each one of which is provided with a mouth. The containers are arranged according to two parallel rows that are opposed to a longitudinal median zone. The mouths of the containers of the upper row are arranged on the upper longitudinal edge of the strip and face upwards, whilst the mouths of the containers of the lower row are arranged on the lower longitudinal edge and face downwards. The method enables productivity to be increased and waste to be reduced.

Abstract: A forming apparatus for forming at least one continuous strip of containers comprises a feed line for the indexing along a preset route according to an advancing direction and with a preset advancing step two continuous webs in film material that face each other. The webs pass through a heat-sealing station provided with a separator the end of which is arranged to be inserted between two open longitudinal flaps of the webs. During the phase of heat-sealing of the webs the separator is kept in position to exert downward pressure against said flaps by means of an axial fluid actuator. The invention ensures that at the forming station, that is contiguous with and subsequent to the heat-sealing station the flaps are sufficiently separated to receive the nozzles that blow in the forming fluid.

Abstract: In a continuous strip of containers, the latter are distributed stepwise from one another according to a longitudinal axis of the strip, two adjacent containers being separated by a step. From one longitudinal edge zone traction pins protrude laterally that are intended in use to interact by contact with an advancing device for advancing the strip. For each traction pin a corresponding opposing projection is prearranged that protrudes from the opposite side of the longitudinal edge zone. The strip is designed to be conveyed along an advancing direction that is parallel to a longitudinal axis thereof. Each opposing projection is located slightly forward in relation to said advancing direction, compared with the relative traction pin, at an axial distance that is shorter than the step between the containers.

Abstract: A device for transversally cutting into portions a continuous strip of containers comprises a severing station arranged to receive the different containers of the strip in a preset severing position, one after another, intermittently. A dragging drum, that is commanded to rotate by a brushless motor provided with a controller, is peripherally provided with seats that are arranged around in a circumference and are coupled with the containers so as to make the strip to advance towards the severing station. A sensor, arranged upstream of the severing station, detects the position of each container and supplies to the controller a corresponding position signal used to correspondingly command the strip to advance so as to correctly position said container in the preset severing position. The device enables the different containers of the strip to be divided with great accuracy.

Abstract: In the process of the invention a strip of containers (5) made of a heat-formable material is guided through a deviated course in a transversal direction with the respect to a main horizontal line of advancement (F), in which the strip of containers undergoes, in sequence, a fist rotation of a quarter of a full turn about a vertical-axis first guide (6), a first twist by half a full turn, a second rotation, by half a full turn, about a second guide (7) having a winding axis which is parallel to the line of advancement (F).

Abstract: In the process and machine of the invention, two strips (A and B) of heat weldable material are supplied, reciprocally facing one another, in an advancement direction (F). The strips are welded at predetermined welding zones and give rise to cells (4) each having at least one opening (5). A part of the welding zone which surrounds the cell (4) is cut, folded and inserted, together with the cell (4), in a forming cavity (71). A forming fluid is injected into the opening to expand the cell internally of the forming cavity. The invention enables plastic containers to be made which are free of projections in the welding zone and which have a low risk of container leakage through the welding seams on the lateral walls and on the bottom of the container.

Abstract: The apparatus includes advancement clamps which move two mutually facing films along an advancement direction on which the following are arranged in sequence: two welding half-molds, which by mutually welding the two films in preset regions define cells which are open toward a longitudinal edge of the films; two half-molds for heating the welded films; a cell forming station. Air injection nozzles, inserted between the two flaps of the films on the side of the above mentioned longitudinal edge, and two forming half-molds, in which forming cavities are defined at the cells, operate in the forming station. Divaricators for divaricating the two flaps of the films are provided proximate to the forming station so as to facilitate the insertion of the air injection nozzles.
