Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
A method for the long-term pressing of printed products, especially newspapers, each of the products having a product spine, comprising the steps of: providing an imbricated arrangement of the products so as to define an imbricated product stream; feeding the printed products in the imbricated product stream so as to move in a first predetermined direction with the product spine leading; tightly winding the thus infed imbricated product stream while moving in said predetermined direction into a wound package; unwinding the wound package and rewinding the previously wound package while moving the unwound imbricated product stream in a direction opposite to said predetermined direction so that the product spine trails; tightly rewinding said imbricated product stream while moving in said other direction into a rewound package; and both the initial winding of the package and the rewinding of the unwound package into a rewound package is accomplished by infeeding the product stream from below into the package being wound.
Claim 2
Independent Claim
159 words
A method for the long-term pressing of printed products, especially newspapers, each of the products having a product spine, comprising the steps of: providing an imbricated arrangement of the products so as to define an imbricated product stream; feeding the printed products in the imbricated product stream so as to move in a first predetermined direction with the product spine leading; tightly winding the thus infed imbricated product stream while moving in said predetermined direction into a wound package; unwinding the wound package and rewinding the previously wound package while moving the unwound imbricated product stream in a direction opposite to said predetermined direction so that the product spine trails; tightly rewinding said imbricated product stream while moving in said other direction into a rewound package; and both the initial winding of the package and the rewinding of the unwound package into a rewound package is accomplished by infeeding the product stream from below into the package being wound.
Claim 3
Dependent Claim
46 words
The method as defined in claim 1, further including the steps of: winding into the wound package both during the initial winding thereof and during the rewinding thereof a separation layer which is under tension and which is incorporated between wound plies of the wound package.
Claim 4
Independent Claim
71 words
A method for the long-term pressing of printed products, especially newspapers, each of the products having a product spine, comprising the steps of: respectively winding an imbricated product arrangement initially with the product spine thereof leading and then in an opposite direction with the product spine trailing into respective wound packages; and infeeding to the package being formed the imbricated product arrangement from below to such package which is being formed.
Claim 5
Independent Claim
71 words
A method for the long-term pressing of printed products, especially newspapers, each of the products having a product spine, comprising the steps of: respectively winding an imbricated product arrangement initially with the product spine thereof leading and then in an opposite direction with the product spine trailing into respective wound packages; and infeeding to the package being formed the imbricated product arrangement from below to such package which is being formed.
Claim 6
Independent Claim
129 words
An apparatus for the long-term pressing of printed products, especially newspapers, comprising: means for winding printed products present in an imbricated product stream onto a winding mandril to form a wound package; means for rewinding the wound package onto a different winding mandril; means for supplying a separation element from below onto a related one of the winding mandrils which constitutes the winding mandril taking-up the wound package; said means for supplying the separation element comprises a brakable supply spool for the separation element; said separation element having an end thereof attached to the winding mandril which is in the process of taking-up the wound package; means for withdrawing the separation element wound into the package; and means for braking the winding mandril which is paying-off the wound package.
Claim 7
Independent Claim
129 words
An apparatus for the long-term pressing of printed products, especially newspapers, comprising: means for winding printed products present in an imbricated product stream onto a winding mandril to form a wound package; means for rewinding the wound package onto a different winding mandril; means for supplying a separation element from below onto a related one of the winding mandrils which constitutes the winding mandril taking-up the wound package; said means for supplying the separation element comprises a brakable supply spool for the separation element; said separation element having an end thereof attached to the winding mandril which is in the process of taking-up the wound package; means for withdrawing the separation element wound into the package; and means for braking the winding mandril which is paying-off the wound package.
Claim 8
Dependent Claim
60 words
The apparatus as defined in claim 4, further including: rocker means having a stationary end; said separation element being guided about said stationary end of said rocker means; said rocker means having a free end region; and pressing means for pressing the free end region of said rocker means in the direction of a related one of the winding mandrils.
Claim 9
Dependent Claim
119 words
The apparatus as defined in claim 5, wherein: said winding mandrils comprise two winding mandrils arranged in spaced relationship from one another to be driven in opposite rotational sense; said rocker means comprising at least two rockers, each rocker being associated with one of the winding mandrils; said rockers associated with the winding mandrils extending towards one another from their free rocker ends and forming a coherent guide means for the printed products; infeed means for infeeding the printed products in the direction of the free end of one of the rockers; said infeed means terminating in spaced relationship above said guide means; and the winding mandril operatively associated with said one rocker being provided with a disconnectable brake.
Claim 10
Dependent Claim
26 words
The apparatus as defined in claim 4, wherein: said means for winding-up the printed products and for rewinding the printed products comprise substantially the same structure.
Claim 11
Dependent Claim
26 words
The apparatus as defined in claim 4, wherein: said means for winding up the printed products and for rewinding the printed products comprise respectively different structure.
