Document Type and Number:
Japanese Patent JP2594793
Kind Code:
B2
Abstract:
In a machine for forming, filling and closing brick-shaped containers for beverages or the like, a heat-sealable web (1) is supplied along a horizontal or inclined supply path and then deflected downward along a substantially vertical treatment path along which the web is formed into a tube, sealed to form a longitudinal seam (8), filled with the liquid contents and then transversely squeezed, sealed and severed to form individual rectangular container units (9). In order to place the longitudinal seam (8) out of the center of a side face of the container and preferably along the edge formed by two adjoining side faces, the vertical deflection of the web is combined with a twisting of the web so as to bring the web plane into an angle of less than 90 DEG to the vertical plane defined by the supply and treatment paths. This is obtained by two subsequent deflections of the web around two deflection rollers (3, 5) arranged one above the other and having their axes horizontal but at an angle to each other. Between these deflection rollers the web forms a loop around a slack absorbing or tensioning roller (4).
