1.7.3.3 Problem of Load Support
It is stated in Para. 1.7.2, "Study of Maximum Plies for Troughin" that the belt must be adaptable to the carrier angle. If the belt is too soft, it may be deformed and caught in the gap between 3-roll troughing idlers because the carriers are angular. In such a case it is feared that the belt will cause ply separation. Table 1.27 shows the study of mini- mum number of ply in such a case.
Table 1.23 Weight of Lump (kg) When the actual weight of the lump is known (or can be calculated), its value is to be used. As an expedient please use the following Table. -Please note, however, that in this Table cubic materials are used for the sizes up to 150 mlm, and rectan- gular or plate like materials are used for the sizes of more than 150 mm.
