摘要： A metal sheet is formed into an arcuate contour by rolling the sheet under high pressure on an elastomeric pad (24) supported by a rigid frame. A pair of laterally spaced rollers (30, 32) are used to form the arc. Each moves from the transverse edge of the sheet inwardly and crosses the center line of the sheet. Under the high pressure applied to the rolls the sheet yields to form the arc and the elastomeric material elastically deforms as the arc is formed. The rollers depend from vertical guides (34, 36) which follow a track extending transversely across the sheet. A guide track (38) is provided in a transverse beam located above the rolls and the guides. Hydraulic or pneumatic jacks (70) apply pressure to the beam which in turn applies pressure to the rolls.

摘要： A process and apparatus for continuously transforming a flat metal strip into an elongated pipe, in which the strip is fed through a forming tool along a curved forming path wherein the longitudinal edge portions are progressively turned up into cross-sectionally arcuate portions leaving between a substantially cross-sectionally rectilinear section, the width of which progressively decreases during travel of the strip through the forming tool. The curved forming path in the tool is such that it has a radius of curvature R(z) in its longitudinal direction, the arcuate portions each having a radius r.sub.o and the decreasing width of said rectilinear section being 2x(z) (wherein z is the distance of travel through the tool). The radius of curvature R(z) is controlled in sole dependence on r.sub.o and the differential quotient x'(z). In the resulting elongated tube, relative differences in travel distance between arbitrary areas in a transverse cross-section of the strip forming the pipe are substantially completely eliminated without plastic deformation in the longitudinal direction.
摘要翻译：一种用于将扁平金属带连续地转变成细长管的方法和装置，其中，条带沿着弯曲成形路径被输送通过成形工具，其中纵向边缘部分逐渐变成截面弧形部分，横截面直线部分，其宽度在带材穿过成型工具的行进期间逐渐减小。工具中的弯曲成形路径使得其在其纵向具有曲率半径R（z），弧形部分各自具有半径ro，并且所述直线段的减小宽度为2x（z）（其中z为通过工具的距离）。曲率半径R（z）仅依赖于ro和微分商x'（z）来控制。在所得的细长管中，形成管的条的横截面中的任意区域之间的行进距离的相对差异基本上完全消除，而在纵向方向上没有塑性变形。

摘要： A slitter attachment for roll former machines, which slits metal in a position forwardly of the feed table of the roll former machine and conveys it through the feed channels of the table to different laterally spaced portions of the rolls. Hinged by a lateral hinge pin to be raised out of position and lowered into engagement with the gear train of the roll former machine, the powered conveyor of the slitter has a laterally slidable support arm surrounded above and below by a cog belt. At the remote end of the arm are slitter rolls driven by the cog belt, whose lower run moves over one of the feed channels toward the rolls of the machine. A magnet, positioned just above this part of the cog belt, lifts the slit workpiece against its under surface and conveys it into the rolls of the machine.
