C. Lewinsohn CONFIDENTIAL Copy of .eanuficrli.i report by Mr, W. J. Ellison dated 10th January I DC 8_____________ S.A. Blue - Former Production nt Rociidolo Bctwcon the wars, there was a section, situated at the North end of 'E' Elock which produced bluo yarn, singly doubled and "metallic'*. There wore about 8 double cards capable, on singlo shift, of producing about IS, 000 lbs. of sliver weekly. Also spinning and doubling framos to deal with this. TIxjoo yams were chiefly for Quaoi-arc and their use was for covering the metal core of welding rods. The yarns were sent out on cardboard tubes, non-returnable and this eliminated cheese winding. TIm section was Isolated (Its own dust collection etc.) in order to avoid the contamination of white by bluo in the waato treatment etc. A small amount of contamination white Into blue didn't matter but blue into white was not permissible for electrical reasons. Tilts electrode trade was a profitable one and persisted for many years. During periods of low demand wo built up large stocks of yam In casco and tlsm kept production at uniform level. Bluo fibre rope at Rochdale you know about. Bluo cloth was woven at Rochdale for various purposes. Mostly for insulation. Bluo cloth was nover proofod for packings because blue isfar too abrasive to be in contact with moving parts. For the same reason it was not used for platted packings. hi tbo early days* beforo w took over Roberts* wo processed bluo filter fibre for Hawaii's* Washington. There was a considerable trade in this. The mass of fibro was not all blue* there was some white with it. 1 am not quits sure whether wo at Rochdale mods all tbo cloth for mattress making at Armloy. Certainly the yam was spun at Armlcy bin for tl lifo of me I cannot recall doth looms tboro. I could chock on this lf it is important for you to know. continued.... * -2- Perhaps the ono important point you wished to establish boa boon provided in those r-'ton, i.o. that there was substantial opening, carding and spinning of blue fibre at Rochdale between the wars end that thoro eras a section sot apart for this processing. There were many comings and goings between oursolvos and J.W.R., Leeds (transfers of cards, spinning frames, etc.). If you wish to have details of these 1 shall need to do come "digging". Perhaps a special medical note re Amoslte may be of interost. In splto of the virtues of Amoslte as on insulator I steadfastly refused to process it at Rochdale. I warn convinced that it was lethal when released to the atmosphere. (There were many reasons for this and 1 will enumerate them If you wish John Knose know my views). Sir Samuel and I had a battle royal and to his groat credit bo eventually issued on edict "no dry processing of Amoslte"- W. J. Ellison (signed)
