摘要:
It is an object of the present invention to provide a method of and an apparatus for manufacturing a resin coated metal sheet, in which it is possible to reduce bubbles included between a laminated resin film and a metal sheet even when a thermoplastic resin film is laminated onto a web-shaped metal sheet even at high speed, and the laminated resin film is excellent in formable adhesion. The method of manufacturing a resin coated metal sheet comprises the steps of heating a web-shaped metal sheet (1), which advances continuously, supplying a thermoplastic resin film (5), which is heated to below a softening temperature of the thermoplastic resin film and to at least a surface temperature of a lamination roll (7), to a nip of the lamination rolls while maintaining the thermoplastic resin film at a higher temperature than the surface temperature of the lamination roll (7), and pressure-welding the metal sheet (1) and the thermoplastic resin film (5) against each other to laminate them.
摘要:
A resin laminated metallic sheet having excellent adhesion during forming, corrosion resistance, and impact resistance is continuously manufactured at high speed with consistent properties is constantly kept at a selected and variable traveling speed of the metallic sheet by controlling the orientation of resin film after lamination, heating the continuously traveling metallic sheet, laminating resin films on both sides of the heated metal sheet using laminating rolls, and thereafter deflecting the traveling direction of the resin laminated metallic sheet using a deflector roll disposed movably in a direction perpendicular to the direction at a right angle from traveling direction of the metallic sheet, and further, differentiating a contacting period of time in which each surface of the resin laminated metallic sheet is contacting each of the laminating rolls, or differentiating an amount of the heat of each surface portion of the resin laminated metallic sheet lost by the cooling effect due to the contact of the resin laminated metallic sheet with the laminating roll.

It is an object of the present invention to provide equipment for manufacturing a laminated metal sheet, which eliminates bubbles even in high speed lamination of 200 m/min or more and is excellent in productivity. In the equipment for manufacturing a laminated metal sheet according to the present invention, a metal sheet (1) is laminated with a resin film (3) on one or both side of it by lamination rolls (2), and a support roll (5) is disposed on projected beyond a straight line between the lamination roll (2) and a film roll (6) so as to impart tension to the film (3) when the film (3) is fed to the lamination rolls (2) from the film roll (6). Further, the support roll (5) is provided directly before the lamination roll (2) so as to satisfy the relation of L.times.V.ltoreq.600 when the lamination speed is V (m/min) and the length of the resin film between the lamination rolls and the support roll is L (m).

A method of producing a laminate board (10) involves the steps of heating a continuous belt-like metallic sheet (2) by a heating furnace (1), laminating a thermoplastic resin film (3) on at least one of the surfaces of the metallic sheet, pressing and passing both of them between a pair of laminate rolls (4 and 5), and thermally bonding the film (3) to the metallic sheet (2), wherein the laminate sheet (10) coming out from between the pair of laminate rolls (4 and 5) is pushed by a deflector roll (6) in a transverse direction so as to bias the travelling direction towards the laminate roll (4) in contact with the film (3). The invention also discloses an apparatus (A) used for his method.
摘要:
A laminate of an oriented resin film and a metal sheet substrate is used in the manufacture of can stock, the intensity of orientation of the resin film being greater along the bottom of the can and lesser along the can side wall. This construction is obtained by locally cooling, during lamination, that part of the heated metal substrate which will become the bottom wall of the resultant can.
摘要:
A bolt fastening method enabling the same effect as when reducing the coefficient of friction of a thread surface without changing the coefficient of friction of the thread surface so as to realize an increase in a bolt axial force generated when fastening the bolt and a bolt fastening device realizing the bolt fastening method are provided.The bolt fastening method of the present invention is a bolt fastening method for when using a bolt having a bolt head and a bolt shank provided with an external thread to fasten fastened members, characterized by intentionally biasing surface pressures of a thread surface and a bolt bearing surface generated when fastening the bolt by imparting a lateral load parallel to the bolt bearing surface to the bolt head and, in that state, imparting a rotational torque rotating the external thread to the bolt head so as to fasten the bolt.

摘要:
A liquid mixture containing a liquid polymeric material and a granular filler is injected into a mold (11) for centrifugal molding and subjected to centrifugal molding, thereby preparing a cylindrical body including a homogeneous dispersion layer (2) having the filler homogeneously dispersed in the polymeric material and a high-density packed bed (1), formed on the outer peripheral surface side or on the inner peripheral surface side of the homogeneous dispersion layer (2), containing the aforementioned polymeric material more densely filled with the aforementioned filler. The high-density packed bed (1) is removed for exposing the surface of the homogeneous dispersion layer (2). According to this structure, the yield of the elastic cylindrical body can be improved.
