    • A roller tool having material-deforming rollers the axis of rotation of which extends lengthwise of and forms an angle with the longitudinal axis of a tube to be secured, is inserted into that portion of the tube which is located within the confines of a passage of the support. The roller tool is then rotated in contact of its rollers with the inner circumferential surface of the tube, so as to form at one axial location of the tube a corresponding outward face deformation of the tube in the passage. During this time, axial displacement of the roller tool relative to the tube is prevented until the outward deformation has reached a desired dimension in direction radially outward of the tube. When this dimension is reached, the rotation of the roller tool is continued but the roller tool is now also permitted to advance axially of the tube so as to form a second outward deformation in the latter axially adjacent the first one. An apparatus for carrying out the method is also disclosed.
    • 一种滚子工具,其具有材料变形辊,其旋转轴线纵向延伸并与待固定的管的纵向轴线形成一角度,插入到管的该部分内,该管的该部分位于 支撑。 然后,滚子工具随着其辊与管的内圆周表面接触而旋转,以便在管的一个轴向位置处形成管在通道中的对应的外表面变形。 在此期间,防止辊工具相对于管的轴向位移,直到向外的变形在管的径向外侧的方向上达到期望的尺寸。 当达到这个尺寸时,滚轮工具的旋转是继续的,但是滚筒工具现在也被允许在管的轴向前进,以便在轴向相邻于第一个方向上形成第二向外的变形。 还公开了一种用于执行该方法的装置。
