Abstract
Abstract An apparatus for selecting and separating articles, such as blanks, comprising article selection means intended to bear upon the edge of essentially vertically arranged articles in such a manner that during displacement of a stream of such articles in such a manner that during displacement of a stream of such articles the article selection means successively follows or moves over each article edge. A separator or knife is located transverse to the articles with respect to the direction of flow of the stream of articles. This separator or knife is intended to bear upon the selection means and serves to penetrate between two successive articles without coming into contact with both of these articles at the beginning of its penetration between two such articles. There is also provided means for adjusting the pressure exerted by the selection means upon the edge of the articles.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
An apparatus for selecting and separating articles, especially blanks, comprising means for conveying the articles in a predetermined direction of travel, a flexible thin resilient blade biased against the stack at all times and having a downwardly inclined portion mounted so that one end bears upon the edges of the moving articles which are essentially vertically arranged in such a manner that said blade follows the article edges during displacement of a stream of said articles, a separator mounted for movement in a plane substantially perpendicular to the direction of flow of said articles and movable to a position engageable with said one end of said flexible blade to cause said flexible blade to move between two successive articles without injuring either of said articles at initiation and during penetration bEtween said two articles and so as to create a temporary gap in the stack which allows the separator to penetrate between two successive articles without injury to their edges, and means for adjusting the pressure exerted by said flexible blade upon the edges of said articles.
Claim 2
Independent Claim
177 words
An apparatus for selecting and separating articles, especially blanks, comprising means for conveying the articles in a predetermined direction of travel, a flexible thin resilient blade biased against the stack at all times and having a downwardly inclined portion mounted so that one end bears upon the edges of the moving articles which are essentially vertically arranged in such a manner that said blade follows the article edges during displacement of a stream of said articles, a separator mounted for movement in a plane substantially perpendicular to the direction of flow of said articles and movable to a position engageable with said one end of said flexible blade to cause said flexible blade to move between two successive articles without injuring either of said articles at initiation and during penetration bEtween said two articles and so as to create a temporary gap in the stack which allows the separator to penetrate between two successive articles without injury to their edges, and means for adjusting the pressure exerted by said flexible blade upon the edges of said articles.
Claim 3
Dependent Claim
31 words
The apparatus as defined in claim 1, wherein said end of said flexible blade makes an angle of less than 90* with a plane defined by the tops of said articles.
Claim 4
Dependent Claim
40 words
The apparatus of claim 1, wherein said separator comprises a generally flat body member and a thin flexible member attached to said body member and extending downwardly therefrom so as to engage said downwardly inclined portion of said flexible blade.
Claim 5
Dependent Claim
16 words
The apparatus of claim 3, wherein the lower end of said thin flexible member is blunt.
Claim 6
Dependent Claim
61 words
The apparatus as defined in claim 4, wherein said flexible blade has an inclined end portion, said downwardly inclined end portion of said blade and said lower end portion of said thin flexible member are substantially parallel, and wherein said lower end of said thin flexible member engages said one end of said flexible blade to force it between successive articles.
