The invention provides a device for receiving an overload in a spine
processing station of a book binding
machine. In order that the back of the body which inserts into a clamp and is conveyed at the back
processing station may process it, show around through between a support roller of
position fixing, and press rollers in the state where it was inserted, and the press roller, linear movement is possible and so that thickness of the back which should be processed may be adjusted via a linear guide and a spindle driving device the spindle driving device, with an adjusting driving device, a spindle with a
screw thread pivotable at a motor ceremony, It has a slidable internal thread mountain element to a spindle with the
screw thread accommodated in rotation impossible, a spring
elastic component connected with the spindle driving device is provided, and this spring
elastic component, it is set up by an interval between the press roller and the support roller, which can be grasped by a sensor in order that displacement of a spindle with the
screw thread may be enabled and the displacement may specify page number of the body, when target thickness of the back guided in between the press roller and the support rollers is exceeded in equipment which absorbs an overload. A driving shaft of the adjusting driving device, and an end by the side of an adjusting driving device of a spindle with the screw thread, it is slidably connected mutually impossible along a rotating shaft line of a spindle with the screw thread via a length compensation element, the spring
elastic component is the inside of a hollow chamber provided in a housing of a spindle with the screw thread, equipment which having extended in same axis to a rotating shaft line of a spindle with the screw thread, and being supported by the driving shaft at the first end, and supporting inside a housing of a spindle with the screw thread at the second end and which absorbs an overload.
