ABSTRACT:
An end wall 1 is composed of a plate 11 which forms, on the front side, a flat surface with an annular attachment 35, whereas the reverse side is reinforced by radial ribs 5 and annular ribs 14. The radial ribs 5 are stiffened by webs 32 which run perpendicular to the plate 11. Further webs 33 reinforce rounded webs 17 of locking lugs 4. On the front side of the plate 11 is disposed a central plug-in peg 2 which is surrounded by the annular attachment. Three sides walls 13 of the plate 11 are provided with stacking lugs 9, 19 which delimit stacking pockets 8, 18 which are designed in a manner complementary to the stacking lugs. The fourth side wall 30 of the end wall has a corrugation 31 and, in the case of a wound roll packaged with the end walls, lies on a pallet. The annular attachment prevents contact between the edge region of the wound roll and the end wall thereby avoiding compressions in the edge region of the wound roll.
