A vacuum gripping element and device hold a component to be transported when subjected to a vacuum. The device includes a carrying device and at least one vacuum gripping element connected releasably to the carrying device as needed. The element includes a base body with at least one vacuum supply channel and an elastic, form-flexible sealing element. A locking coupling forms a first fastener for positively connecting and releasing the gripping element relative to the carrying device as required. Alternatively, the base body includes first and second base body parts, the first part positively connecting and releasing relative to the carrying device as required by the first fastener, and the second part being connected to the elastic, form-flexible sealing element. A locking coupling forms a second fastener for positively connecting and releasing the first base body part relative to the second base body part as required.

A bending machine with a bending information display apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam. The longitudinal expanse and the press beam movement direction define a working plane. An insertion plane essentially normal to the working plane is defined by an upper machine table flat side or a lower tool disposed thereon. The working plane establishes a front working and manipulation space and a closed rear machine space. A projector disposed above the insertion plane in the rear machine space has a light beam path directed away from the insertion plane. A reflector disposed in the working and manipulation space has a first reflective surface pivotable by an angle to the horizontal so that a light beam incident from the projector beam path leaves the first reflective surface as a departing light beam toward the insertion plane.

A back gauge for a back gauge positioning system of a bending machine includes a stop finger on which at least one stop surface is configured, and a base unit that is configured for coupling with the back gauge positioning system. The stop finger is coupled with the base unit by a linear guide, and the stop finger can be displaced relative to the base unit between a pushed-forward working position and a retracted position. The stop finger and the base unit are coupled with a first spring element, by which the stop finger is pre-loaded into its working position, and a locking device is configured, by which the stop finger can optionally be locked in the working position or is released into its retracted position for displacement counter to the spring force of the first spring element.
