ABSTRACT:
The inherent tendency of printed products, especially newspapers, to change their shape, for instance, because of residual stresses or a restoring action, is to be annihilated by subjecting the printed products to a pressing or compression action. By winding-up the printed products arranged in an imbricated formation and by rewinding the same in the opposite winding sense the products are initially curved in a first direction and then in another direction and pressed into a flat condition. Already during the time that the products are wound into a product package the products become more uniform, as such possibly would be otherwise attainable due to the action of pressure forces over longer periods of time with the utilization of a great amount of equipment expenditure. The winding and rewinding, but also the unwinding, as these terms are used herein, constitute operations accomplished with the aid of a separation or partition element which is under tension, the end of such separation element being connected with the related winding mandril and being wound into the wound package.
