Abstract
Multi-sheet products (D), particularly printed products, are opened, for example for the insertion of supplements. For this purpose, according to the method of the invention sheet edges, which in the closed product lie one on the other, are in a first step separated from each other so as to fan out by means of a gas current directed onto these edges, and in a second step an opener (71) is pushed between two of the fanned-out sheet edges, the edges being held stable in a separated position through the continuous action of the gas current until at least a part of the opener has been pushed between the sheets.
Claims22
An apparatus for inserting insertion objects between the sheets of multi-sheet products, comprising
- means for supporting and sequentially advancing the multi-sheet products along a path of travel with the products being in a closed state and so that the products each define an end face,
- nozzle means positioned along the path of travel for directing a gas current (LS) in a direction substantially parallel to the surfaces of the sheets and against the end face of each product, so as to separate at least two neighboring sheets from each other in at least one location, and
- means for relatively moving at least one insertion object and each of the advancing products so that the insertion object is pushed between the separated sheets of each product.
A method for inserting insertion objects between the sheets of multi-sheet products (D), comprising a first method step in which at least two sheet edges, lying one on the other when the product is in the closed state, of two neighboring sheets are separated from one another at least in one or more places, and a second method step in which the insertion object is pushed between the separated sheet edges, characterized in that said first method step includes directing a gas current (LS) substantially parallel to the main planes of the sheets, towards an end face,, formed by separable sheet edges lying one on the other, of the closed product, and said second method step includes introducing an insertion object between two sheet edges which are held separated by the gas current.
