Abstract
Abstract The apparatus has two generally parallel transport means in the form of chains guided within tracks. Double armed levers are attached to the chains which carry clamping rollers, whose surfaces are of elastically yielding material. Folded printed matter is supplied to the clamping rollers of both transport means in a shingled stream. Every two printed items are folded within each other but displaced laterally by a distance A. The clamping rollers grasp the edges of the printed items and transport them. After grasping the printed matter, the transport means diverge, whereby the printed items which are folded within each other are also automatically drawn apart.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
Apparatus for transporting and separating folded printed items, which are supplied from a rotary machine on a conveyor in a shingled stream, and in which every two printed items are folded within each other but displaced laterally from each other, and in which the apparatus has as its grasping means rollers attached to an endless transport means guided within tracks, each roller bearing resiliently against at least one adjoining roller and grasping the printed items at their edge between the rollers and transporting them, characterized in that an endless transport means with rollers is positioned laterally on both sides of the shingled stream, the guidance tracks of both transport means being turned within a horizontal region shortly after grasping of the printed items by the rollers longitudinally by a predetermined angle, in such manner that the two transport means diverge in V configuration after being turned by about 90° into a vertical region and draw apart the printed items folded within each other.
Claim 2
Dependent Claim

Apparatus for transporting and separating folded printed items, which are supplied from a rotary machine on a conveyor in a shingled stream, and in which every two printed items are folded within each other but displaced laterally from each other, and in which the apparatus has as its grasping means rollers attached to an endless transport means guided within tracks, each roller bearing resiliently against at least one adjoining roller and grasping the printed items at their edge between the rollers and transporting them, characterized in that an endless transport means with rollers is positioned laterally on both sides of the shingled stream, the guidance tracks of both transport means being turned within a horizontal region shortly after grasping of the printed items by the rollers longitudinally by a predetermined angle, in such manner that the two transport means diverge in V configuration after being turned by about 90° into a vertical region and draw apart the printed items folded within each other.
Claim 3
Dependent Claim
42 words
The apparatus of claim 1 characterized in that the endless transport means whose rollers grasp the edge of the outer one of the two printed items folded within each other moves about 1 to 10% more rapidly than the other transport means.
Claim 4
Dependent Claim
17 words
Apparatus according to claim 1 characterized in that the spacing between the two transport means is adjustable.
