Abstract: In a filter press having filter frames arranged parallel to each other so that they may be opened and closed, a liquid-feed metallic member, positioned at a side portion of the filter frame for feeding liquid to be processed to each filter chamber formed between adjacent filter frames, is fixedly secured to one of two links pivotably mounted with pins onto the respective adjacent filter frames in such manner that in response to opening and closing of the filter frames the liquid-feed metallic member may be automatically engaged with and disengaged from recessed portions of the filter frames. These recessed portions communicate with said filter chamber via filter cloths.

Abstract: An improved forming apparatus for a breaker layer to be used in a radial tire is described herein. The apparatus essentially comprises a drum device (D), a press contact device (A), first and second breaker material folding-wrapping devices (B) and (C), means for rotating said drum device (D), and means for moving said respective devices (A), (B) and (C) in the axial direction relative to said drum device (D) and for fixing them at predetermined positions. The drum device (D) includes a plurality of segments which have a width of their outer circumferential surfaces approximately equal to the width of the breaker layer to be formed, which can form a substantially cylindrical press contact surface with their outer circumferential surfaces, and which can expand and contract the diameter of said cylindrical contact surface.
