摘要： A rolling process for long solid-section products includes the steps of rolling stock through a plurality of rolling mill stands, the rolled stock being subjected to a tensile load, between the plurality of stands, that generates a single-axial deformation greater than 0.1 in the rolling direction, and is also deformed by compression between the rolls of at least one of the rolling mill stands, thereby achieving a reduction in the cross section area of at least 5%, preferably of between 5 and 50%. A rolling mill, in which a plurality of stands is connected by spacer elements designed to offset the tensile load; a rolling mill, in which a plurality of stands is connected by elements designed to offset the overturning moment generated by the tensile load; and a rolling mill, in which the aforesaid rolling stands maintain a non-slip condition.

摘要： The invention relates to a sealing device for installation in a roll arrangement between the roll journals of a roll and chock. The sealing device has an annular main body having sealing rims that extend radially outwards. Furthermore, the sealing device has an annular reinforcement element having a strip-like section which coaxially surrounds the main body on the outer side thereof. In order to ensure the dimensional stability and thus also the function of the sealing device even after the installation thereof in the roll arrangement, that is to say after said sealing device has been pushed onto the frustroconical roll journals, the reinforcement element according to the invention has, in addition to the coaxial strip-like section, at least one flange which is connected thereto and is connected to the sealing rim. Furthermore, the invention relates to said roll arrangement.

摘要： Provided are a bending method and a bending apparatus for bending a medical suturing needle into different curved shapes by using one bending top. The bending apparatus comprises a reciprocally rotatable bending top, and a belt having such a flexibility as can be wound on the outer circumference of the bending top. The bending method curves a medical suturing needle by sandwiching and constricting a material for the medical suturing needle between the bending top and the belt and by rotating the bending top reciprocally in the winding direction and in the rewinding direction. In the bending method, the curved shape of the material is changed by changing the winding angle of the belt to be wound on the outer circumference of the bending top thereby to change the area for constricting the material. The bending apparatus (B) comprises a reciprocally rotatable bending top (11), and a belt (12) having such a flexibility as can be wound on the outer circumference of the bending top (11), and is constituted such that a winding angle (θ) for the belt (12) to be wound on the outer circumference of the bending top (11) is changed.
