Device for monitoring the lubrication status of a circulating belt loaded with a lubricant

The invention relates to a device for monitoring the lubrication status of a circulating belt (4) loaded with a lubricant for the transport of press material， in particular in a continuously operating press (1)， with at least one first detection device (4) arranged in the area of ????the belt (4). D1) of a first type and with at least one second detection device (D2) of a second type arranged in the region of the belt (4). The monitoring device is characterized in that the first detection device (D1) is set up to generate a quantity signal that is dependent on the amount of material on the belt (4) and that to differentiate a lubricant on the belt (4) from on the Band (4) located dirt particles or a lubricant contaminated with dirt particles， the second detection device (D2) is set up， to generate a material signal (S2) which is dependent on the type of material on the belt (4).
