Abstract
Abstract Method and apparatus for indexing a predetermined number of flat articles which form a group within a continuous series of such articles being conveyed by counting the articles, with means provided therefor, as they are conveyed until the predetermined number in the group is reached and then displacing, with means provided therefor, one of the articles, either the first or the last in the group, a short distance transverse to the direction of conveyance so that it extends laterally beyond one side of the series of articles.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
Apparatus for indexing a predetermined number of flat articles which form a group within a continuous series of such articles being conveyed, comprising, in combination: a. means for individually conveying along a predetermined conveying path a continuous series of flat articles which are in spaced relationship with one another, said individual conveying means having at least a first portion and a second portion, said second portion being dimensioned in the direction of the said conveying path to substantially correspond to the dimension of the articles in the same direction and being arranged along said conveying path and in the same horizontal plane as said first portion; b. means arranged downstream of said second portion for receiving said articles therefrom and conveying them in an overlapping fashion; and c. means mounted on said individual conveying means for alternatingly moving said second portion in opposite directions transverse to said conveying path for alternatingly displacing a selected one of said articles a predetermined lateral distance from said conveying path in one direction and displacing another selected article a predetermined lateral distance from said conveying path in the opposite direction from the first article, so as to indicate successive groups of a predetermined number of the articles.
Claim 2
Dependent Claim
203 words
Apparatus for indexing a predetermined number of flat articles which form a group within a continuous series of such articles being conveyed, comprising, in combination: a. means for individually conveying along a predetermined conveying path a continuous series of flat articles which are in spaced relationship with one another, said individual conveying means having at least a first portion and a second portion, said second portion being dimensioned in the direction of the said conveying path to substantially correspond to the dimension of the articles in the same direction and being arranged along said conveying path and in the same horizontal plane as said first portion; b. means arranged downstream of said second portion for receiving said articles therefrom and conveying them in an overlapping fashion; and c. means mounted on said individual conveying means for alternatingly moving said second portion in opposite directions transverse to said conveying path for alternatingly displacing a selected one of said articles a predetermined lateral distance from said conveying path in one direction and displacing another selected article a predetermined lateral distance from said conveying path in the opposite direction from the first article, so as to indicate successive groups of a predetermined number of the articles.
Claim 3
Dependent Claim
50 words
Apparatus as defined in claim 1, wherein said second portion is mounted for movement in opposite directions between two opposed end positions along a path transverse to said conveying path and said moving means moves it from one said end position to the other only when displacing a selected article.
Claim 4
Dependent Claim
49 words
Apparatus as defined in claim 1 wherein said second portion includes two coacting pairs of relatively short endless conveyor belts; and said moving means includes a pair of transversely moveable frames, each of said pairs of conveyor belts being disposed in one of said frames for transverse movement therewith.
Claim 5
Dependent Claim
79 words
Apparatus as defined in claim 3 wherein said first portion includes two assemblies, said assemblies being adjustable and arranged parallel with respect to each other in order that the distance between them can be varied; and one of said two pairs of endless belts being arranged at each of said assemblies for receiving said articles, respectively therefrom, said two pairs of conveyor belts being disposed in a common plane transverse to the direction in which said articles are conveyed.
Claim 6
Dependent Claim
38 words
Apparatus as defined in claim 4 wherein said moving means further includes two hydraulic actuators, one of said hydraulic actuators being connected to each of said movable frames, respectively, whereby said pairs of conveyor belts are transversely moved.
Claim 7
Dependent Claim
62 words
Apparatus as defined in claim 5 further comprising a counting means, said counting means including a sensor at said conveying means for signaling the presence of an article, said counting means being connected to said hydraulic actuators whereby, upon the predetermined number of articles being registered by thE counting means, a signal is emitted to the hydraulic actuators to move said frames.
