The invention relates to a cable drum in the sidewalls of which-made of sheet metal-radial waves are formed; the dimensions of the wave increase as they advance from the center towards the flange. The corrugated side of the cable drums can be manufactured in different sizes by using one single tool. The cable drum can be produced either in a rigid, or in a collapsible form. In a folded state the width amounts about 1/8 of the rigid cable drum. For the transport and storage of the folded cable drum a container may be used with an enclosing dimension corresponding to a full cable drum, in which 7-8 folded drums can be transported and stored, respectively. |
