Abstract
Abstract To insert a plurality of insert sheets (2') simultaneously into multi-sheet products (2), for example folded inserts into already folded newspapers, a first carrier structure (3,3') retains the multi-sheet products in essentially open V-shaped position. A second carrier structure, located above the first carrier structure, retains the insert sheets. In accordance with the invention, for insertion, an auxiliary holder (19-26) grips insert sheets from the second carrier structure and, upon spreading apart of the first carrier structure, and downward movement of the auxiliary holder, transfers the inserts into the multi-sheet products. If the first carrier structure does not retain any multi-sheet products, the arrangement can also be used for transfer from one carrier structure to another and also to remove defective sheets from the second carrier structure by gripping them and depositing them on a defective-sheet transport belt (54).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
184 words
Sheet insertion apparatus to place insert sheets (2') into a first carrier structure (3, 3'), particularly into folded sheet products (2) supported on the first carrier structure, wherein the first carrier structure (3, 3') is adapted to retain a plurality of folded sheets in essentially V-shaped open position, said carrier structure defining V-shaped open pocket-like elements; a second carrier structure (4, 4') is provided, located at a predetermined position at least approximately parallel to said first carrier structure, and retaining a plurality of said insert sheets (2') for transfer of each of the respective insert sheets to said first carrier structure and into said open pocket-like elements, and comprising an auxiliary holder system (19-26) operatively associated with second carrier structure (4, 4'), including means for individually holding each of said plurality of insert sheets (2') and means for moving second carrier structure (44') away from said predetermined position after said individual holding means are holding said insert sheets to permit insertion of the insert sheets (2') into said first carrier structure (3, 3') upon release of the insert sheets (2') by said holder means.
Claim 2
Dependent Claim
184 words
Sheet insertion apparatus to place insert sheets (2') into a first carrier structure (3, 3'), particularly into folded sheet products (2) supported on the first carrier structure, wherein the first carrier structure (3, 3') is adapted to retain a plurality of folded sheets in essentially V-shaped open position, said carrier structure defining V-shaped open pocket-like elements; a second carrier structure (4, 4') is provided, located at a predetermined position at least approximately parallel to said first carrier structure, and retaining a plurality of said insert sheets (2') for transfer of each of the respective insert sheets to said first carrier structure and into said open pocket-like elements, and comprising an auxiliary holder system (19-26) operatively associated with second carrier structure (4, 4'), including means for individually holding each of said plurality of insert sheets (2') and means for moving second carrier structure (44') away from said predetermined position after said individual holding means are holding said insert sheets to permit insertion of the insert sheets (2') into said first carrier structure (3, 3') upon release of the insert sheets (2') by said holder means.
Claim 3
Dependent Claim
84 words
The apparatus of claim 1, wherein each of said carrier structures comprise zig-zag or accordion-shape connected elements adapted to be collapsed against each other or drawn out or expanded to form said V-shaped open pocket-like elements; rails (29, 29'; 37, 37') positioning said pocket-like elements and permitting, respectively, compression or expansion thereof; and drive means (8, 8'; 9, 9') engageable with said pocket-like elements and, respectively, moving said pocket-like elements longitudinally of said rails and maintaining said pocket-like elements in expanded V-shaped open position.
Claim 4
Dependent Claim
74 words
The apparatus of claim 1, wherein said auxiliary holder means (19-26) comprises holder arms (19, 19') engageable between said pocket-like elements of the second carrier structure and triangular elements (26) engageable from above into said pocket-like structure and adjacent an insert sheet (2'), said triangular elements (26) and said holder arms (19, 19') being relatively movable in a direction transverse to the major plane of said insert sheets for gripping said insert sheets therebetween.
Claim 5
Dependent Claim
151 words
The apparatus of claim 2, wherein said auxiliary holding means (19-26) comprises holder arms (19, 19') engageable between said pocket-like elements of the second carrier structure and triangular elements (26) engageable from above into said pocket-like structure and adjacent an insert sheet (2'), said triangular elements (26) and said holder arms (19, 19') being relatively movable in a direction transverse to the major plane of said insert sheets for gripping said insert sheets therebetween; and wherein the rails (4, 4') of the second carrier structure are laterally movable, the auxiliary holder system being vertically movable for introducing said insert sheets into said first carrier structure (3, 3'), the first carrier structure, upon such introduction, being laterally movable to permit placement of said insert sheets (2') up to a folded edge thereof into said first carrier structure and into folded sheet products (2) retained therein under guidance of the auxiliary holder systems.
Claim 6
Dependent Claim
95 words
The apparatus of claim 4, wherein said first carrier structure retains folded sheet products (2) in at least some of said open pocket-like elements; and, after insertion of the insert sheets (2') into the respective folded sheet products in the first carrier structure, the open pocket-like elements of the first carrier structure being movable towards each other; and wherein said open pocket-like elements include V-shaped fingers (5, 5') engageable between insert sheets (2') introduced by said auxiliary holder system for retaining said insert sheets adjacent the folded sheet products retained in the first carrier structure.
Claim 7
Dependent Claim
52 words
The apparatus of claim 1, further including a first drive means (8, 8') engageable with said pocket-like elements of the first carrier structure; and a second drive means, which second drive means is an endless drive means (9, 9') engageable with respective open pocket-like elements of the second carrier structure (4, 4').
Claim 8
Dependent Claim
66 words
The apparatus of claim 1, further including a guide element (40) located beneath the first carrier structure (3, 3') and positioned for engagement with a folded back of folded sheet products retained on said first carrier structure; and removal transport means located beneath said first carrier structure and positioned for reception of folded sheet products upon passage of said folded sheet products over said guide element.
Claim 9
Dependent Claim
