Abstract
Abstract A method of, and apparatus for, opening folded, multi-sheet paper products, especially folded newspapers, specifically for the purpose of introducing an insert into the thus opened paper product, wherein a pressure is exerted at the region of the fold of the paper product, this pressure extending transverse to the plane of the product itself. As a result the sheets of the product located to one side of the fold are raised from the sheets located at the other side of the fold. In accordance with a preferred constructional embodiment of the invention there is provided a clamping member equipped with a pressure element and a counterelement, the printed product is introduced between these elements in order to carry out the product opening activity.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
82 words
A method of opening folded, multi-sheet paper products, especially for introducing an insert into the opened paper product, comprising the steps of exerting a pressure at the region of a fold of the folded multi-sheet paper product, which pressure is directed transverse to the plane containing the product, and by means of the exerted pressure lifting the sheets of the product disposed to one side of the fold from the sheets of the product disposed to the other side of such folds.
Claim 2
Independent Claim
82 words
A method of opening folded, multi-sheet paper products, especially for introducing an insert into the opened paper product, comprising the steps of exerting a pressure at the region of a fold of the folded multi-sheet paper product, which pressure is directed transverse to the plane containing the product, and by means of the exerted pressure lifting the sheets of the product disposed to one side of the fold from the sheets of the product disposed to the other side of such folds.
Claim 3
Dependent Claim
32 words
The method as defined in claim 1, including the step of exerting the pressure closer to one side edge merging with the fold than another side edge also merging with the fold.
Claim 4
Dependent Claim
35 words
The method as defined in claim 2, especially for opening paper products which have been twice folded, including the step of exerting the pressure at the corner between the main fold and a side fold.
Claim 5
Dependent Claim
43 words
The method as defined in claim 1, further including the step of lifting the paper product into an inclined position with the fold of the paper product being located lowermost and extending approximately horizontally, and thereafter exerting the pressure upon the paper product.
Claim 6
Dependent Claim
39 words
The method as defined in claim 4, including the step of conveying the paper product in a direction extending substantially parallel to the fold of the paper product, and exerting the pressure during such conveying of the paper product.
Claim 7
Dependent Claim
52 words
The method as defined in claim 1, including the step of additionally bending the section of the paper product disposed between the fold and the point of application of the pressure about a bending axis which is parallel to the fold and in the same direction as the effect of the pressure.
Claim 8
Dependent Claim
33 words
The method as defined in claim 1, including the stp of exerting the pressure at a locally limited region of the paper product, and wherein the paper product is kinked at this region.
Claim 9
Independent Claim
81 words
An apparatus for opening folded multi-sheet Paper products, especially for the introduction of an insert into the opened paper products, comprising means providing a contact surface for guiding the fold of each paper product, clamping means provided along the path of guiding of the paper products which comprises at least one pressure element and a counterelement, each paper product being insertable between said pressure element and counterelement, and conveying means for introducing such paper products between said pressure element and counterelement.
Claim 10
Independent Claim
81 words
An apparatus for opening folded multi-sheet Paper products, especially for the introduction of an insert into the opened paper products, comprising means providing a contact surface for guiding the fold of each paper product, clamping means provided along the path of guiding of the paper products which comprises at least one pressure element and a counterelement, each paper product being insertable between said pressure element and counterelement, and conveying means for introducing such paper products between said pressure element and counterelement.
Claim 11
Dependent Claim
36 words
The apparatus as defined in claim 8, further including an endless revolving chain, said pressure element being secured to said endless revolving chain, said counterelement comprising a conveyor band driven for synchronous movement with said chain.
Claim 12
Dependent Claim
20 words
The apparatus as defined in claim 8, wherein each said pressure element is in the form of a press roll.
Claim 13
Dependent Claim
36 words
The apparatus as defined in claim 8, wherein said pressure element is provided with a sharpened edge at the side thereof which is effective for exerting the pressure in order to simultaneously kink the paper product.
Claim 14
Dependent Claim
103 words
The apparatus as defined in claim 8, wherein said counterelements comprises a conveyor band having a substantially horizontally disposed conveying surface for the purpose of conveying the paper products with its fold freely laterally protruding, an endless revolving chain moving in the same direction as said conveyor band, said pressure element comprising a press roll secured to said endless revolving chain and cooperating with said freely laterally protruding fold, a bending device arranged laterally of said conveyor band by means of which said freely laterally protruding fold of the paper product is flexed until extending beneath the conveying surface of the conveyor band.
