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
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.

The invention claimed is: 1. Continuous strip of containers comprising: a plurality of containers extending stepwise one after another along longitudinal direction of the strip, so that corresponding points of two adjacent containers are separated by a step; said strip of containers having at least one longitudinal edge zone having a side from which traction pins protrude laterally, said pins being intended to interact in use by contact with an advancing device for advancing the strip; said strip comprising, for each of said traction pins, at least one corresponding opposing projection that protrudes from a further side of said at least one longitudinal edge zone, said further side being opposite to said side; wherein each said at least one corresponding opposing projection is arranged at a distance from its relative traction pin along said longitudinal direction, said distance being shorter than said step. 2. Strip according to claim 1, wherein said distance is shorter than half said step between the containers. 3. Strip according to claim 1, wherein said strip comprises, for each container, said at least one traction pin and said at least one corresponding opposing projection. 4. Strip according to claim 1, wherein both said traction pins and said opposing projections, are distributed with a step that is equal to said step between the containers. 5. Strip according to claim 1, wherein said at least one longitudinal edge zone of said strip is configured in a sinuous manner so as to alternate, with a step that is equal to said step between the containers, a full zone occupied by the material of said strip and an empty zone that is free of the material of said strip. 6. Strip according to claim 5, wherein each traction pin, and each relative opposing projection are both situated in the same full zone. 7. Strip according to claim 5 wherein each full zone has a traction pin and its relative opposing projection. 8. Method of advancing by means of an advancing device a strip of containers, said strip comprising a plurality of containers arranged one after another so that corresponding points of two adjacent containers are separated by a step, said strip having at least one longitudinal edge zone having a side from which traction pins protrude laterally at least one opposing projection being provided for each of said traction pins, each said at least one opposing projection protruding from a further side of said at least one longitudinal edge zone that is opposite to said side, said traction pins being intended to interact in use by contact with said advancing device, wherein said advancing device comprises: an advancing guide for advancing said strip in an advancing direction that is parallel to a longitudinal direction of said strip, said advancing guide being defined laterally by two running surfaces that are parallel to each other and are provided to contain said at least one longitudinal edge zone of said strip; at least one dragging member prearranged to push the strip of the containers in said advancing direction, said at least one dragging member being movable in a direction parallel to the advancing direction and having at least one thrust elements prearranged to interact by contact with the traction pins; wherein when one said traction pin contacts said at least one thrust element, the opposing projection associated with the one said traction pin contacts a running surface of said two running surfaces, that flexure of the strip of containers due to the action of the thrust element. 9. Method according to claim 8, wherein each opposing projection is located slightly forward, in relation to said advancing direction, compared with its relative traction pin, at a distance that is not shorter than the width of said advancing guide. 10. Method according to claim 8, wherein the width of said advancing guide defined by the distance between said two running surfaces, is substantially equal or slightly greater than the distance, considered in a direction that is perpendicular to the advancing direction, between the side ends of a traction pin and of the relative opposing projection.
