Abstract
A number of circulatory elements arranged one behind the other are driven in a direction of circulation and have a suction element and a supporting element in each case on the first side and on the second side. The circulatory elements receive a supplementary product at the pick-up location and transfer the same, in a first mode of operation, to the respectively preceding circulatory element. In a second mode of operation, no transfer takes place. This results in it being possible for the supplementary products received in the same manner to be brought into abutment optionally against the leading side or trailing side of the printed products and pressed on there.
Claims16
An apparatus for supplying supplementary products to printed products and pressing them onto the latter, having a number of circulatory elements which are driven in a direction of circulation along a continuous circulatory path, are arranged one behind the other and have a suction element at least on one side and a supporting element at least on the other side, and having a control arrangement for the location-dependent control of the circulatory elements, it being the case that the circulatory elements are intended for picking up a supplementary product by means of the suction element at a pick-up location and pressing it onto a printed product at a press-on location, for which purpose the circulatory elements, during their movement from the pick-up location to the press-on location, are moved in between printed products, which are conveyed at a distance apart from one another, and are moved toward one another, with the result that one circulatory element positions itself, by way of the retained supplementary product, on one side of the printed products in each case and an adjacent circulatory element positions itself, by way of the supporting element, on the other side, wherein the circulatory elements have a suction element and a supporting element on both sides in each case, and each suction element, for the purpose of controlling its connection to a negative-pressure source, is assigned a suction valve.
