Abstract
Abstract An apparatus for conveying and turning articles is provided by the combination of a through belt which extends along the path of the articles parallel to a conveyor belt and cooperates therewith for the purpose of conveying the articles in a line, and a control roller and a pair of pressing rollers which trap the article therebetween and turn it at least one complete revolution in place.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
234 words
Apparatus for conveying articles proceeding on a line conveying device to a testing station and for rotating the articles at the testing station, comprising: a conveyor belt disposed laterally of the line conveying device; means for driving said conveyor belt; a through belt disposed laterally of the line conveying device and spaced from said conveyor belt and cooperating therewith to define a track for conveying the articles at spaced intervals from one another to the testing station; means for driving said through belt; a control roller disposed on one side of said track, said control roller being displaceable between an operating position in which a portion of its periphery extends over said through belt and into said track, and a rest position in which its periphery lies outside said track; a first pressing roller disposed adjacent the side of said track opposite that of said control roller, said first pressing roller being pivotable transversely with respect to said track; and a second pressing roller disposed adjacent the side of said track opposite that of said control roller and downstream of said first pressing roller, said second pressing roller being rotatably disposed on a fixed shaft, said control roller and said first and second pressing rollers cooperating to interrupt the passage of articles proceeding through said track and to rotate each article at least one about the axis of the article at the testing station.

Apparatus for conveying articles proceeding on a line conveying device to a testing station and for rotating the articles at the testing station, comprising: a conveyor belt disposed laterally of the line conveying device; means for driving said conveyor belt; a through belt disposed laterally of the line conveying device and spaced from said conveyor belt and cooperating therewith to define a track for conveying the articles at spaced intervals from one another to the testing station; means for driving said through belt; a control roller disposed on one side of said track, said control roller being displaceable between an operating position in which a portion of its periphery extends over said through belt and into said track, and a rest position in which its periphery lies outside said track; a first pressing roller disposed adjacent the side of said track opposite that of said control roller, said first pressing roller being pivotable transversely with respect to said track; and a second pressing roller disposed adjacent the side of said track opposite that of said control roller and downstream of said first pressing roller, said second pressing roller being rotatably disposed on a fixed shaft, said control roller and said first and second pressing rollers cooperating to interrupt the passage of articles proceeding through said track and to rotate each article at least one about the axis of the article at the testing station.
Claim 3
Dependent Claim
32 words
Apparatus for conveying and turning articles as defined in claim 1, wherein said means for driving said through belt are adjustable to vary the speed at which said through belt is driven.
Claim 4
Dependent Claim
26 words
Apparatus for conveying and turning articles as defined in claim 1, wherein said control roller is displaceable along a path which is inclined to said track.
Claim 5
Dependent Claim
60 words
Apparatus for conveying and turning articles as defined in claim 1, wherein said control roller is rotatably disposed on a pivoting arm whereby the point on the periphery of the control roller which is farthest from the pivot of said pivoting arm describes an arc of a circle during displacement of said control roller between the rest and operating positions.
Claim 6
Dependent Claim
48 words
Apparatus for conveying and turning articles as defined in claim 1, wherein said first and second pressing rollers bear against the side of said conveyor belt opposite from said track whereby said conveyor belt partially surrounds and bears against an article which is being rotated about its axis.
Claim 7
Dependent Claim
48 words
Apparatus for conveying and turning articles as defined in claim 1, wherein said first pressing roller is rotatably disposed on a pivotable arm, said arm being biased towards a rest position and pivotable out of the rest position by the entry of an article into the testing station.
