Abstract
PURPOSE:To partially roll-form a sash-shaped long-sized material by making a table to fit a sash-shaped long-sized material and a direct-acting cam integrated with this table take a shape corresponding to the curvature of a sash-shaped long-sized material and raising and lowering a forming roll after a direct-acting cam when the table goes forward. CONSTITUTION:A clamp face 16 corresponding to the curved shape of the sash-shaped long-sized material W is provided on the table T and the direct-acting cam 18 is fitted at one end. In addition, a fitting protruding bar 22 fitting to a recess 20 formed on the back of a protruding part 14 of the sash-shaped long-sized material W is provided on the clamp face 16 in a longitudinal direction. The cam curved line of the direct-acting cam 18, too, takes a shape corresponding to the curved shape of the sash-shaped long-sized material W. Roll stands S1-S4 are mounted at a fixed interval on the way of a reciprocating linear motion course, form rolls R1-R4 respectively different in shape are rotatively fitted on a fixture 24, catchers H1-H4 different in shape are fitted to the fixture 24, the sash-shaped long-sized material W is roll- formed between this form roll and the catcher, the upper end of a raising part 12 is bent inward to form a bent part 28.
