Abstract:
A bending machine for flat material, comprising:a machine frame, a lower beam arranged on the machine frame, said lower beam having a lower clamping tool, an upper beam arranged on the machine frame, said upper beam having an upper clamping tool, said flat material being fixable in a clamping plane with said beams, a lower bending tool moving device associated with the lower beam for moving a lower bending tool carrier with a lower bending tool for bending the flat material about an upper bending edge relative to the clamping plane between a rest position and a plurality of bending positions, an upper bending tool moving device associated with the upper beam for moving an upper bending tool carrier with an upper bending tool for bending the flat material about a lower bending edge relative to the clamping plane between a rest position and a plurality of bending positions, and the bending tool not used for an operation on the flat material and its corresponding bending tool carrier being adapted to be brought from a starting bending position into a rest position where the bending tool carrier is located closer to a front surface of the respective beam in the rest position than in the starting position and where a bending space free from machine elements of the bending machine exists between the clamping plane and the bending tool located in the rest position and its bending tool carrier, said space extending over an angular area of at least 100Â° around the respectively operative bending edge.
