摘要： Upon roll-forming an end plate of hemispherical and other cup-like or dish-like configurations, a raw material disc is placed between outer die means consisting of a top outer forming die that can be vertically moved by a drive source and can be freely rotated and at least a pair of left and right outer forming rolls adapted to move along predetermined moving paths and inner die means consisting of a top inner forming die held at a predetermined position that can be driven in rotation by a drive source, and a middle inner forming roll a bottom inner roll both of which are freely rotatable, the outer die means is depressed against the inner die means, and said pair of outer forming rolls are moved along said moving paths so as to press said raw material disc against the middle inner forming roll and the bottom inner forming roll, respectively, one of said outer forming rolls being moved within an effective forming range of the middle inner forming roll, while the other being moved within an effective forming range of the bottom inner forming roll. The effective forming ranges of the middle and bottom inner forming rolls, respectively, are partly overlapped with each other. In an apparatus for effecting the above-described roll-forming operation, an effective forming angle of the bottom inner forming roll is chosen larger than an effective forming angle of the middle inner forming roll.

摘要： An improved method and apparatus for grinding a rotary body, in which a rotatably supported grindstone is positioned in such manner that an extension of a rotary axis of the grindstone does not intersect a rotary axis of the rotary body and the rotary axis of the grindstone is inclined with respect to a plane perpendicular to the rotary axis of the rotary body to be ground. The rotary body to be ground is rotatably driven, and the grindstone is pressed against the outer circumferential surface of the rotary body to be ground in order that the outer circumferential surface of the rotary body to be ground can be ground by a relative slip produced at a contact point between the outer circumferential surface of the rotary body to be ground and the grindstone.

摘要： In a method of rolling a strip between work rolls with small and large diameters, while tensioning and bending the strip, the diameter ratio of the small and large work rolls is chosen from the range of 1/1.5 to 1/10, at least one of the work rolls or of rolls in a group backing up the work rolls is driven, and the strip is rolled as it is forced through the work rolls while being bent toward or around either the small or large work roll at a strip entry-exit angle between 5.degree. and 30.degree..
