Abstract: A feeder for flat objects, particularly a supplement feeder for supplements, having a stack compartment for receiving objects in the form of a stack and a takeoff device for taking individual objects off the stack along a takeoff direction, wherein the takeoff device includes a conveying element and a gate, through which the objects taken off the stack are led individually by the conveying element. In order to be able to process different objects with properties differing from one another, particularly objects of different type and thickness, with the feeder in continuous operation without problems and without congestion and to provide a feeder for different objects that is as flexible as possible and that is capable of processing both thick and thin objects without lasting deformations while largely avoiding takeoff errors, the gate has a first gate device and a second gate device.

Abstract: A control device for paint spraying systems and application systems which are used, in particular, for the quick-change application of paint in batch productions, with a piping system (1) carrying fluids, such as paint, lacquer, coating particles, and solvents of different cleanliness classes, with individual separating elements, such as pigs (15), enabling a fluid separation inside the piping system (1), is characterized in that individual control blocks (19, 21, 63) of the control device are composed of a plurality of actuatable switching valves (23, 25, 45, 47, 86, 87, 89, 90, 91), which enable, on the one hand, the input and/or output of pigs and/or, on the other hand, for this purpose, the simultaneous conveying of fluids in the piping system (1).

Abstract: The present invention pertains to a collecting device for sheets 3 for forming stacks of sheets 6 from individual sheets 3 fed in at a stop 26, as well as with a removing device 28 for the stacks 6 formed. To remove the stacks of sheets 6 with a high reliability of operation, the present invention provides for a movable stop 26 and a driven roller arrangement 29, 30, 31, which is mounted such that it can be fed to the stack of sheets 6. On the other hand, the present invention discloses a special, elastic conveying means 8, 11, which guides the sheets 3 onto the stack of sheets 6 along a transport path 7 and over a deflector 16. Both measures can be embodied both as a combination and separately.
