The devices according to the invention comprise two pluralities of hide presence sensors (17, 19) arranged so as to monitor the hide that enters and exits from the conveyor and processing rollers (10, 14, 15) of resetting/retaining and drying machines. A programmable control reverses the motion of the rollers and therefore the processing when a set number of sensors (17, 19) ascertains the absence of the hide while the remaining ones ascertain that the hide continues to be present in their respective monitoring regions. In this manner, the processing cycle is automated.
