A method of securing ears to a chassis web, the method comprising: providing first and second infeeding ear webs; cutting the first infeeding ear web to provide a nested pattern of first and second left ears (12A, 12B), each of the first and second left ears having parallel edges of different lengths, the first left ears in a correct facing orientation in which the shorter parallel edges of the ears face in a first direction and the second left ears in a reversed orientation relative to the correct facing orientation such that the shorter parallel edges of the second left ears face in a second direction opposite to the first direction; cutting the second infeeding ear web to provide a nested pattern of first and second right ears (12A, 12B), each of the first and second right ears having parallel edges of different lengths, the second right ears in a correct facing orientation in which the shorter parallel edges of the ears face in a third direction and the first right ears in a reversed orientation relative to the correct facing orientation such that the shorter parallel edges of the first right ears face in a fourth direction opposite to the third direction; retaining the first and second left ears and the first and second right ears by vacuum; reorienting the second left ears into the left correct facing orientation using an ear turner assembly that expands to a pitch large enough for the ears to be unnested and allow clearance for every other ear to be rotated; reorienting the first right ears into the right correct facing orientation using an ear turner assembly that expands to a pitch large enough for the ears to be unnested and allow clearance for every other ear to be rotated; coupling the first left ears and the first right ears onto an infeeding chassis web to create a first chassis and ear assembly; coupling the second left ears and the second right ears onto the infeeding chassis web to create a second chassis and ear assembly, such that for each pair of first left and first right ears on said first chassis and ear assembly and for each pair of second left and second right ears on said chassis and ear assembly, one of the two ears is rotated through 180°. providing first and second infeeding ear webs; cutting the first infeeding ear web to provide a nested pattern of first and second left ears (12A, 12B), each of the first and second left ears having parallel edges of different lengths, the first left ears in a correct facing orientation in which the shorter parallel edges of the ears face in a first direction and the second left ears in a reversed orientation relative to the correct facing orientation such that the shorter parallel edges of the second left ears face in a second direction opposite to the first direction; cutting the second infeeding ear web to provide a nested pattern of first and second right ears (12A, 12B), each of the first and second right ears having parallel edges of different lengths, the second right ears in a correct facing orientation in which the shorter parallel edges of the ears face in a third direction and the first right ears in a reversed orientation relative to the correct facing orientation such that the shorter parallel edges of the first right ears face in a fourth direction opposite to the third direction; retaining the first and second left ears and the first and second right ears by vacuum; reorienting the second left ears into the left correct facing orientation using an ear turner assembly that expands to a pitch large enough for the ears to be unnested and allow clearance for every other ear to be rotated; reorienting the first right ears into the right correct facing orientation using an ear turner assembly that expands to a pitch large enough for the ears to be unnested and allow clearance for every other ear to be rotated; coupling the first left ears and the first right ears onto an infeeding chassis web to create a first chassis and ear assembly; coupling the second left ears and the second right ears onto the infeeding chassis web to create a second chassis and ear assembly, such that for each pair of first left and first right ears on said first chassis and ear assembly and for each pair of second left and second right ears on said chassis and ear assembly, one of the two ears is rotated through 180°.
