Abstract: A cutting device for use in cutting a cylindrical material around a mandrel into annular bodies of the desired width. This device has a first moving table to move in the axial direction of the mandrel, a second moving table to move on the first moving table in the radial direction of the mandrel, a cutter support carrying a first cutter adjustable in position in the radial direction of the mandrel and/or a second cutter adjustable in the axial direction of the mandrel, and a control unit with a device for detecting the position of each moving table, a device for receiving output signals from the detecting device and comparing the position with position data set beforehand and a driving circuit to move each moving table according to output signals from the comparing device.

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.
