Traverse the metal roller (4.1), at a rate of approximately 200 mds along the tapes in one direction then immediately reverse and traverse in the other direction then turn the mating tapes over. Repeat the procedure until the roller has traversed the mating tapes five times

24、in each direction i.e. a total of ten times. Take care that the centre of gravity of the roller does not deviate from the centre line of the tapes during this operation. Take care that the roller covers the entire width of the mating tapes NOTE: The tapes are turned over to minimise curvature. 8 Tes
