B to provide a central area of parallelly disposed strings, then following an outwardly spirallike path B 1 , B 2 , B 3 , B 4 . . .

The strings 2 are interwoven and, as shown, are passed through and anchored by turns of a wire coil 3 embracing the frame 1, the strings forming the central area passing round two adjacent turns of the coil.
