Abstract: The sheet metal brake with side loading rollers (10) includes a plurality of stations (11, 12, 13, 14, 15, 16), each having a lower beam (20) and an upper beam (22). Each of the lower and upper beams (20, 22) has a workpiece clamping element (24, 26) extending therefrom. Each station (11, 12, 13, 14, 15, 16) includes at least one bending tool carrier (42, 44) having a bending tool (46, 48). The at least one tool carrier (42, 44) is movable relative to a corresponding one of the lower and upper beams (20, 22). A plurality of supports (30, 32, 34, 36, 38, 40) selectively carry a workpiece (18) between selected ones of the plurality of stations (11, 12, 13, 14, 15, 16). Each support (30, 32, 34, 36, 38, 40) is selectively vertically adjustable, and may be a set of driven rollers or the like.
