After mixing, the raw materials are extruded in the form of a tape which is wound into a coil. The coil is then placed in an oven for initial curing. Following the initial curing operation, the coils are surface ground anchcut-to length on band-saws. .Depending on. customer^specifications, the.lining.may undergo another curing operation. Finally the linings are drilled with the proper holes, finish ground, inspected, and packaged for shipment. C. ABK Industrial Bearings ABK industrial-bearings are special wear and heat resistant bear ing made by the company. The bearings are made by first impregnating a'cloth with various resins and then winding this doth or hot pressihg'It to form the product.- These bearings are used quite extensively in-iron and steel'-foundries.---*----- -- - ---- -- -- - -- ---- SURVEY PROCEDURES The main purpose of-the asbestos dust survey conducted at the plant was to evaluate the asbestos sampling technique currently used by the U.S. * Public-Health Service. -To do this, simultaneous samples weretaken C85 pairs on the same side of the man and 23 sets on opposite sides) to check, the reproducibility of the asbestos sampling under field conditions withT-relatively low concentrations. The majority of the sampling was conducted at the same machines in the cutting, grinding and drilling of auto'-linings* for7 three consecutive* days'on-the7first and second shift* in order^to^also supply data-on-variations of-concentration of" asbestos with the shift-and day of-week.'-The' remainder of the samples came from the preforming and hot press areas. A special study was done to determine the-effect of heavy background on sample results. A preliminary industrial hygiene survey of the plant was also conducted to try to evaluate general housekeeping and ventilation systems.
