and twistability the hooks 16 must be dimensioned appropriately relative to adjacent hooks 16 the rivets 13 must also be dimensioned appropriately relative to the aperture 26 in which it is inserted although the meaning of the terms stretchability bendability and twistability is generally appreciated reference to fig9 11 and 12 are helpful to understand the unique means by which this fabric 11 is able to achieve these requirements and the importance of the dimensions of the hooks and the rivets in relation to the aperture fig9 a illustrates a line of platelets 12 connected in accordance with the invention fig9 a shows the platelets 12 in a configuration of maximum separation fig9 b illustrates the platelets in a configuration of minimum separation fig9 c is a cross section taken along line a a of fig9 a fig9 c illustrates how the hooks 16 can be pulled to their outer extremities and yet not separate due to the positive engagement of the hooks 16 the hook 16 of each platelet 12 slides along the bottom of its matingly engaged platelet 12 until the maximum stretch or length of the string of platelets 12 is achieved fig9 d is a cross section taken along line a a of fig9 b fig9 d illustrates how the hooks 16 can slide towards the center of each platelet 12 to arrive at the point of least stretch or length bendability of the fabric 11 is illustrated in fig1 a and b where each block denotes one platelet 12 fig1 a shows the fabric 11 as a flat array of platelets fig1 b shows the fabric 11 bent in a curve.
