Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
106 words
Apparatus for changing the conveying direction of bendable paper products or the like brought up continuously in formation, in particular shingled at least two-layer paper products lying on each other, characterized in that the paper products are clamped fixed in formation in a constraining guide, comprising conveying belts having a first direction of travel; a fixed support aligned in a direction different from said first direction of travel, said support carrying a plurality of rollers sequentially mounted along a helical line about said support; and means for guiding said conveying belts over said plurality of rollers, said conveying belts thereby adopting a second direction of travel.
Claim 2
Dependent Claim
106 words
Apparatus for changing the conveying direction of bendable paper products or the like brought up continuously in formation, in particular shingled at least two-layer paper products lying on each other, characterized in that the paper products are clamped fixed in formation in a constraining guide, comprising conveying belts having a first direction of travel; a fixed support aligned in a direction different from said first direction of travel, said support carrying a plurality of rollers sequentially mounted along a helical line about said support; and means for guiding said conveying belts over said plurality of rollers, said conveying belts thereby adopting a second direction of travel.
Claim 3
Dependent Claim
29 words
Apparatus according to claim 1, characterized in that at least one conveyor belt is provided at its product-remote side with projections, and the means for guiding is corresponding formed.
Claim 4
Dependent Claim
16 words
Apparatus according to claim 2, characterized in that each of said rollers is circular in cross-section.
Claim 5
Dependent Claim
19 words
Apparatus according to claim 3, characterized in that the support is stationarily mounted in the form of a cylinder.
Claim 6
Dependent Claim
36 words
Apparatus according to claim 4, characterized in that the support has holes along a helical line, and further comprising a plurality of roller holders mounted in said holes, said roller holders each rotatably supporting a roller.
Claim 7
Dependent Claim
21 words
Apparatus according to any claim 5, characterized in that the conveyor belt and the rollers are less than 15 cm wide.
Claim 8
Dependent Claim
17 words

Claim 12
Dependent Claim
30 words
The apparatus of claim 10, wherein said means for creating a third direction of travel further comprises at least two conveyor belts extending parallel with said second direction of travel.
Claim 13
Dependent Claim
22 words
The apparatus of claim 11, further comprising at least three rollers aligned for guiding each of said at least two conveyor belts.
Claim 14
Dependent Claim
21 words
