Abstract
Abstract Apparatus for opening folded newspapers which arrive from a printing press in imbricated succession and are separated into single copies, comprises conveyor means to carry the folded copies along in spaced relation. Opposite gripping jaws are provided to grip the two folded halves of the newspapers and cause a sliding movement of the two halves relative to each other in a direction at right angles to the fold to expose one edge portion of the folded newspaper while further gripping jaws grip the exposed edge portion and the edge portion of the other half of the folded newspaper. The gripping jaws are attached to endless conveyor means to move along with the moving newspapers and are controlled to open the two halves of the newspapers, while further conveyor means supply enclosures or supplemental sheets to be slipped laterally into the opened newspapers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
235 words
Apparatus for opening folded articles, such as newspapers, comprising a plurality of first grippers each adapted for receiving a folded article and each including a pair of gripping jaws provided with means for gripping both halves of a folded article at a zone remote from the fold of the article, one of said gripping jaws having means for moving said jaw relative to the other jaw in a plane parallel to the plane of the folded article such that one half of the folded article will be offset with respect to the other half, and a plurality of second grippers each adapted to grip the edge portion of the half of the article exposed by relative movement of said halves, each said second gripper including a pair of jaws adapted to grip the opposed faces of said exposed edge portion of said exposed half of the respective folded article, one of said second gripper jaws having a wedge-shaped back arranged to allow the edge portion of the second of said halves of the folded article to ride up said back when said edge portion of the second of said halves has been released by the associated first gripper and is shifted back to overlie the exposed portion of said one of the halves of the folded article, and endless circulating conveyor elements connected to the first and second grippers to operate the same in synchronism.

Claim 3
Dependent Claim
57 words
Apparatus as claimed in claim 1 comprising a plurality of third grippers each associated with a second gripper and each including a pair of gripping jaws adapted to grip the edge portion of the second half of a respective folded article after movement thereof up said wedge-shaped back of said one jaw of an associated second gripper.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claim 1, wherein the gripping jaws on said first grippers comprise points projecting towards the folded article.
Claim 5
Dependent Claim
33 words
Apparatus as claimed in claim 1, wherein said first grippers are adapted to be moved relatively to one another in the article gripping position, at right-angles to the fold in the folded article.
Claim 6
Dependent Claim
34 words
Apparatus as claimed in claim 1, wherein said first grippers are so arranged that their gripping areas engage the folded article in the region of one of the two corners remote from the fold.
Claim 7
Dependent Claim
38 words
Apparatus as claim in claim 1, in which one gripping jaw of said first grippers and the other gripping jaw of said first grippers respectively are attached to two distinct endless conveyor elements circulating in substantially parallel direction.
