Abstract: System for releasably attaching a shell segment to a core section of a drum useful in the manufacture of vehicle tires. The system includes an outwardly opening longitudinal groove in the outer surface of the core section and a like groove in inner surface of the shell segment. These grooves are designed to overlie one another and cooperatively define a channel when the segment is positioned in overlying relationship to the core section.

Abstract: Improved B and C backing bearing assemblies and second intermediate idler rolls, characterized by greatly reduced transverse rigidity, for use in 20-high cluster mills having a 1-2-3-4 roll arrangement. On each of the B and C backing assemblies, spacers are used to provide narrow gaps between the roller bearings and the shaft eccentrics so that they do not form a rigid tube about the shafts of the B and C backing bearing assemblies. Segmented bridge elements are provided to transfer the load from the middle to each side of each roller bearing. Tie means, tying all the parts together axially (including the roller bearings the eccentrics, the bridge means and the spacing means), are provided in a form which is flexible in transverse bending. The idler roll of the second intermediate rolls constitutes a solid, rod-like, transversely flexible core, mounting a series of slightly spaced rings to form the roll body.

Abstract: A guide roller for a printing press is designed to prevent foreign matters, such as ink or so forth from adhering on the peripheral surface thereof and to sweep up the peripheral surface by a traveling web. The guide roller comprises a roller body having a peripheral surface to contact with a traveling web. The roller body incorporates a first peripheral surface for converting the traveling speed of the web into a first rotational speed and a second peripheral surface having a different geometry to the first peripheral surface for converting the traveling speed of the web into a second rotational speed, the second peripheral surface being cooperative with the first peripheral surface for interacting the second rotational speed with the first rotational speed for determining a rotational speed of the guide roller so that the peripheral speed of the guide roller is differentiated from the traveling speed of the web.

Abstract: A method for manufacturing a cylindrical mantle of rolls or cylinders of a paper machine out of a corrosion-proof metal or alloy material, particularly refined steel, in which oblong plate blanks are cut to a length equal to the total length of the roll mantle to be manufactured. The plate blanks are machined or bent to mantle portions of a cross-sectional shape equal to a part of a circular ring. Out of the mantle portions, the cylindrical mantle of a roll or cylinder is assembled by joining the mantle portions together by means of axial welding joints prepared by electron-beam welding performed in the vacuum chamber of an electron-beam apparatus by using a number of mantle portions per one roll mantle. A roll or cylinder manufactured by the method is also described.

Abstract: A roll stamper used in a process of continuously forming a uniform sheet of a resin from which information recording medium bases are obtained. This roll stamper has a stamper member having in its surface a pattern corresponding to a pre-format pattern of an information recording medium, fixing members fixed on opposite end portions of a reverse surface of the stamper member so as to be integral with the stamper member, and a specular roll base having an engagement groove formed in its circumferential surface parallel to its axis. The stamper member is fixed on the specular roll base by fitting the fixing members in the engagement groove. A recess formed in a circumferential surface of the roll stamper as a gap between the fixing members is filled with a filler so that the roll stamper circumferential surface is substantially smooth. Side surfaces of the fixing members and/or the engagement groove are shaped as to suitably retain the filler.

Abstract: The invention relates to a machine for compacting and/or crushing bulk material, in which two rollers which can be pressed together at high pressure each consist of a main roller body and a roller shell which is releasably connected to the main roller body and is composed of individual segments. Each of the individual segments has one single lug projecting in the circumferential direction on the front long side in the direction of rotation of the roller and one single complementary recess on the rear long side in the direction of rotation of the roller. The generatrices of the outer surfaces of the segments point in the circumferential direction and run radially with respect to the roller axis. This results in a simple construction of the segments and a high degree of security against tilting.
