Certain-teed Products Corporation' ^ 6 FOR Paoli Laboratory DATE July 24, 1957 .FROM Fort Dodge OFFICE ATTENTION OF Mr. J. R. Watt ANSWERING YOURS SUBJECT ACCOUSnCAL PIASTER FOR MACHINE APPLICATION DICTATED BY L. 7. Rodenborn - jl cc: Mr. H. J. Zelms- Acme Mr, C. E. Abbey- Ardmore Mr, Myron Read- Fort Dodge With reference to the bags to be used for above product. As ve were requested to bag this material on the open mouth machine, ve vere of the opinion this would be the specified method as it has been in the past on Kalite* Tne open mouth Kalite bags are sewn on the one end and as material is not heavy enough toform a butt for the bag to stand on, we felt a pasted end bag which normally has a butt of about 6 inches would work much better. If it is decided to fill on the Bates packer either type will be satisfactory. With reference to mixing we obtained a practically free from asbestos "bundld* mixture as follows: Hix paddle speed 117, RPM Amount of asbestos is added and mixed for 3 minutes, balance of materials are added and mixed for an additional 3 minutes or a total of six minutes. As there vere a few very small nbundles0 present at above mix we did not try and out mixing time. If the Acme machine has a greater speed they could try cutting time. SGP 0018670
