The respective edges of the support layers (31, 39) are transversely offset to result in a pair of edge regions and some cords (36) are sandwiched between the support layers while at least one cord (32, 33, 40) and (37, 38, 41) is secured to one of the edge regions. Preferably the two edge regions have corresponding cord arrangements (32, 33, 40) and (37, 38, 41) provided such that the cords (32, 33, 40) of one edge region may be caused to interlock with those (37, 38, 41) at the other edge region. |
