摘要:
The invention relates to a method for the production of photopolymerisable cylindrical jointless flexographic printing elements, by application of a layer of photopolymerisable material to the external surface of a hollow cylinder and joining the edges by calendering. The invention further relates to a corresponding device for carrying out said method.

A tire component is fabricated by the steps of forming a narrow belt by arranging a plurality of cords and embedding the cords in a rubber layer, cutting the belt into strips of a predetermined length, and successively arranging and joining a necessary number of the strips such that edge parts of adjacent strips overlap each other with the outermost cord in the edge part of one of the adjacent strips overlying the outermost cord in the edge part of the other strip. The strips can be surely joined without requiring advanced techniques, without wasting materials and without increasing weight. Thus a desired annular tire component can be accurately formed in a desired circumference. The cords are arranged in each strip in a width equal to a length shorter than a length equal to an integral division of the predetermined circumference of a tire by a length corresponding to an increase in the diameter of the tire component. A tire component of a predetermined circumference can be accurately formed by increasing the diameter of an annular ply fabricated by successively joining an integral number of the strips such that the edge parts of the adjacent strips overlap each other with the outermost cord in the edge part of one of the adjacent strips superposed on the outermost cord in the edge part of the other strip. A pneumatic tire including the thus formed carcass ply thus fabricated has an improved quality.

Disclosed is a method of joining at least two linoleum sheets (2, 3). The method includes creating a seam (8) between the linoleum sheets (2, 3) and forming a bead of non-epoxy adhesive (6) on a seam edge (10, 12) or injecting the non-epoxy adhesive (6) into a closed seam. The seam (8) formed by the edges (10, 12) of the linoleum sheets (2, 3) is joined and filled with the adhesive (6). Excess adhesive (6) is removed and the seam is rolled and the seam adhesive (6) is limited to the area between the linoleum sheets (2, 3) and the substrate within one linoleum sheet thickness of the seam (8).

Surface structured decorative boards (1) having a first and a second opposite edge (1?I and 1II¿ respectively). The board (1) include an upper side decorative surface (2) an upper side surface structure and a base layer. The structure is comprised by at least two surface grades (10) forming a decorative surface pattern on said upper side, said pattern being applied in predetermined fixed positions (P) on the first and the second edges (1?I and 1II¿ respectively). The first edge pattern positions (PL) and the second edge pattern positions (PR) are matched so that the pattern continues over the first and second edges (1?I and 1II¿ respectively) of adjacent boards (1).

The present invention provides a studless tire excellent in performance on ice and snow in which digging friction is improved without losing adhesion friction. The studless tire has a tread comprising specific short fiber or plate-like material dispersed in diene rubber so as to be oriented in the tread thickness direction, wherein when measured at 25°C the tread has a complex elastic modulus E1 in the tread thickness direction, and the sheet has a complex elastic modulus Eα in the extrusion direction and a complex elastic modulus Eβ in a 90° direction from the extrusion direction, when the rubber composition is made into 2 mm sheets with a roller and these moduli fulfill the following equation, 60 ≤ (E1-Eβ)/(Eα-Eβ) × 100 ≤ 100 and the tread has a specific tread rubber hardness. The tire is obtained using a tread prepared by extruding a rubber composition containing diene rubber and specific short fiber or plate-type material in a tube shape, thereby orienting the short fiber in the circumferential direction of the tube shaped rubber, then cutting the obtained rubber sheet parallel to the extrusion direction, rotating each piece 90° and laminating.
