    摘要: A method for producing a cylinder tube (2), which is closed at the end so as to be fluid-tight, from a tubular blank (30). The blank (30) is formed into the cylinder tube (2) with the aid of a cold forming method in such a way that on an end region (6) of the cylinder tube (2) an opening (8) remains in the cylinder tube (30), a mounting region (12) is produced in the radially outer edge region (10) of the end region (6) and the cylinder tube (2) is closed by fluid-tight attachment on the mounting region (12) of an end piece (14) which closes the opening (8). A cylinder tube (2) comprises the cylinder tube (2) cold formed from the blank (30) having an opening (8) at the end, the mounting region (12) and an end piece (14) attached to the mounting region (12) so as to be fluid-tight.

    摘要: A method and apparatus in a hot multi-stand tube mill for producing a thin metallic tube having end portions which corresponds to the wall thickness and diameter of the rest of the rolled tube or alternately, tapered ends. Each stand is provided with a set of three cooperating rolls arranged to form a roll pass opening. According to the tube's positioning in the mill, an appropriate additional adjustment of the rolls to decrease or enlarge the roll pass diameter is made in one or all of the last three stands. Both an initial roll setting varying means and an additional roll setting varying means cause movement of wedges abutting the roll chocks thereby causing movement of the rolls.
