ABSTRACT:
In a machine for forming a continuous tube which is then cut up into sections, for example to make containers, a plurality of bands of fibrous, cellulosic, metallic, plastic or other material are drawn from supply reels and pass through a gluing and labelling section where adhesive is applied to one side of the bands and labels are applied to the outer face of the center band. After application of the adhesive and labels, the bands, while continuing to move forwardly, are assembled in superposed relation with the bands laterally displaced relative to one another so that the edges of the assembly of bands are stepped. The bands are pressed together in a narrow central width only so as to bond central portions together while leaving side portions unbonded. The band assembly is then progressively formed into tubular profile, thereby bringing opposite side edges together, and subjected to pressure to bond the bands together throughout their width, bond side edges together and impart the finished shape, which may be circular or polygonal. The tubular profile thus formed is cut into sections while it continues to move forwardly and the sections are discharged from the machine.
