Patent ID: 7090630

Claim:
A machine for forming containers, comprising: a first conveying mechanism comprising at least a first wheel comprising a central hub rotatable about a respective axis, with a plurality of supporting elements projecting radially from the hub and each presenting a first end anchored to the hub and a second end remote from the first end; wherein said first wheel is rotatable in a first feed direction along a first circular sealing path passing through a feed station supplying a single file of tubular elements which are fitted over the respective supporting element, first sealing means positioned downstream of the feed station, relative to the first feed direction, operating on a first open end of each tubular element in such a way as to enclose the selfsame first end; a feed device, placed upstream of the feed station considered in relation to the first feed direction, supplying necks for the containers by placing them on the second end of each supporting element; wherein said first conveying mechanism is movable between a position in which the tubular elements are taken up from the feed station, and a position in which the selfsame tubular elements are offered to the first sealing means; and a second conveying mechanism operating in conjunction with the first conveying mechanism, downstream of the first sealing means considered in relation to the first feed direction, and comprising a second wheel, similar to the first wheel and rotatable in a second feed direction, along a second circular sealing path tangential to the first sealing path; wherein the second conveying mechanism is movable between a position in which the tubular elements are taken up from the first conveying mechanism, and a position in which the selfsame tubular elements are offered to second sealing means operating on a second open end of each tubular element opposite to the first end open, in such a way as to enclose the selfsame second end and complete the container.
