Abstract: A coater and drier system for uniformly depositing a film on a substrate or backing member. A vacuum bar positioned under the substrate is utilized to smooth out and make the substrate uniform as it passes beneath a spreader bar member or roller member in order to provide a layer of film forming liquid material on a substrate of a prespecified thickness.

Abstract: This invention relates to a conveyor means for simultaneously advancing and twisting a plurality of strands into a rope and the process for utilizing these means. The conveyor includes an elongated trough with two walls which are joined to define the linear path. The first wall includes the plurality of aligned rollers having access of rotating with a predetermined angular relationship relative to horizontal and vertical planes as well as a power means for driving the rollers in unison and means for feeding the strands into the trough and in frictional contact with the rollers.
