A method of and apparatus for the automated manufacture of a liner of a cargo container has a work area (35) over which tubular plastics material (15) may be drawn out, for forming the liner. A shuttle (39) is disposed between the layers (18, 19) of the material and is maintained stationary as the material is drawn out, until a portion of the liner (15) to carry an attachment is disposed over the shuttle (39). The shuttle provides a counter-force for the bonding of the attachment (23) (such as an access pipe) to the liner and also serves to hold apart the upper layer (18) of the material from the or each other layer during the bonding operation. The shuttle may have rollers (41) which run on an internal surface of the liner material and may be maintained stationary with respect to the work area by magnets (52, 53) on the work area (35) and the shuttle (39) respectively. Following the drawing of a sufficient length of material while holding the shuttle stationary, the drawn length may be welded across (FIG. 9) to form and end panel for the liner and severed from the remaining material, with the shuttle (39) disposed in the remaining material. |
