<p>Arrangement for the attachment of bendable suction tubes (2) along the side of packing containers (8), whereby the suction tubes (2) which are enclosed in an envelope (3) of flexible plastic material consist of two straight parts (5, 6) divided by a crimped flexible part (7). The suction straws (2) are brought into contact with the packing containers (8) by means of a rotatable drum (13), the axis of which is parallel to the diagonal of the containers (8). One straight part (5) of the suction tube (2) being aligned with the diagonal of a container (8) and transferred to the container side where the envelope (3) of the suction tube will adhere to deposits (16) of heat-activated adhesive material applied on the package side by a die (11) while the other straight part (6) of the suction tube (2) will project from the container side. Said other projection part (6) of suction tube (2) being folded down along the flexible part (7) by means of a plurality of rollers (17, 18, 19) to a position within the contour of the side wall of the container (8) and parallel to the upper side edge of the container (8) and that the folded down part (6) of the suction tube (2) is fixed in the folded down position by means of further rollers (21) which will press the envelope (3) of the suction tube (2) against deposits (16) of adhesive material.</p> |
