Abstract: A deforming machine (1) with a machine frame (2), on which an upper tool (4) and a lower tool (5) are arranged, which form a working gap (8) of variable size, with a first optical safety light barrier (20) for securing a first safety space (28) adjacent to the working gap (8) and with a second optical safety light barrier (30) for securing a second safety space (31), which is located in front of a largest surface (18) of the upper tool (4). The second optical safety light barrier (30) is designed for monitoring a third safety space (51) which extends downwards beyond the end face (6) of the upper tool (4) facing the lower tool (5) along the movement path (14) in the direction of the lower tool (5), so that a projection of the third safety space (51) onto the working gap (8) covers at least a section of the working gap (8).

Abstract: A forming apparatus comprises: a machine bed; a tool holder mounted movably relative to the machine bed; a drive unit connected to the tool holder; a disconnector unit; a machine control for operating the drive unit; and a monitoring device to monitor movements of the tool holder and to activate the disconnector unit. The monitoring unit includes two distance measuring systems that respectively generate first and second position signals at different rates for determining a position of the tool holder relative to the machine bed. At least one radiation beam detector is deactivated in response to a different between the first and second position signals undershooting a predetermined value.

Abstract: A forming device comprising a machine bed, a tool carrier supported on the machine bed in a manner capable of relative movement for mounting a tool, a drive device coupled to the tool carrier, a machine control unit and a monitoring device designed for monitoring movements of the tool carrier and for providing a shutdown signal to a disconnecting device located upstream of the drive device on the occurrence of a pre-settable monitoring case. It is provided that the machine control unit is designed in accordance with a first safety category of a safety standard, and that the monitoring device and the disconnecting device form a safe operating system designed in accordance with a second safety category of the safety standard, the second safety category being at a higher level than the first safety category within the safety standard.
