摘要
Apparatus for forming, from a flat metal strip, a contoured section having a constant profile which prevails throughout the length of the section and is progressively applied to the strip by advancing the strip longitudinally into and through the working ambit of complementary first and second forming dies; said apparatus comprising, a machine frame, a pair of carriers which have said forming dies respectively mounted thereon, means for mounting one of said carriers on said frame so that the die carried thereby is able to move relative to said frame with a first component of reciprocatory motion normal to the second of said dies and with a second component of reciprocatory motion in the direction of strip advancement between said dies, means for mounting the second of said carriers on said frame so that the die carried by it is movable relative to said frame at least in the said direction of strip advancement, and drive mechanism whereby at least said first die is driven in exercise of its movability as aforesaid, and so that at all times of operation said dies remain spaced apart at least by a pre-selected minimum distance.
