A method and apparatus for manufacturing a rubber sheet containing short fibers. The present invention employs an ester derived from 1,5-pentanediol having one alkyl side chain and saturated monovalent fatty acid having 5 to 8 carbon atoms as a base oil of a lubricant with which a gap between a shaft and a sleeve is filled. The first arc segment, also called the segment guide, is an arc of 160-330 degrees with a circular cross-section and a rounded edge. In response to the user actuation, the actuatable device prevents the processor from adjusting the operational parameter of the electronic system. The principal components pck are stored in a matrix Mpc. Particularly contemplated adhesion promoters may further comprise styrene-butadiene-vinylpyridine copolymer, and may advantageously be employed as a replacement for resorcinol-formaldehyde latex in the fabrication of a rubber containing tire.
