Abstract
In order to form an improved junction which is less liable to tear under shock loads, a diamond pattern of holes (or depressions) is formed in plastics material sheet. The holes are then in two sets of parallel lines each making an angle to the subsequent stretching direction and the holes are also in parallel rows at right angles to the stretching direction. The sheet is stretched so that the zones between adjacent holes in each line form orientated strands and the zones between adjacent holes in each row form junctions which have their lateral zones orientated but have a central zone which is unorientated or less orientated, i.e. which is thicker. The central zone can extend into two opposite crotches or be completely surrounded by highly orientated lateral zones.
