Abstract: An optoelectronic sensor for safeguarding a hazardous area, such as a light grid, has a first and a second sensor part. The two sensor parts are arranged at a spatial distance from one another. Each sensor part has a plurality of transmitting elements for generating transmitted beams and a plurality of receiving elements for receiving the transmitted beams. In this way, a plurality of transmitted beams in opposite directions are formed between the sensor parts. Each sensor part has at least one evaluation circuit, which is coupled to the receiving elements of the respective sensor part. Each evaluation circuit is designed to generate a switch-off signal in a manner dependent on the respectively coupled receiving elements. In a preferred configuration, each sensor part has a plurality of evaluation circuits which are coupled to one another to form a series arrangement of evaluation circuits, and which are additionally coupled to a common data bus connection.

Abstract: A rolling device for rolling up a sheet onto roll formers or spools: a roll former is inserted between and supported on two supporting rollers and a sheet is wound on it; the finished wound roll on its roll former is lifted off one of the supporting rollers looping the sheet, and the slack loop section is stapled to the next roll former; the sheet is cut off at the new roll former.
