Abstract
Abstract In a conveyor incorporating a flexible track (4) being guiding and supported on at least two beams (2, 3), which are angularly adjustable relative to each other, the two beams (2, 3) are arranged in a row after each other with an interspace between them and interconnected to each other by means of a joint. The track is guided by two sliding ledges (15, 16, 17, 18) which are jointed (19, 20) adjacent the interspace. A portion (21, 22) of each sliding ledge overlaps the interspace between the beams and is slidably arranged on a supporting edge of the beam on which the joint of the sliding ledge is situated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A conveyor incorporating a flexible conveyor track (4), guided and supported by at least two beams obliquely adjustable relative to each other and in a row one after the other with an interspace therebetween and interconnected by a pivotal link means, characterized therein, that the conveyor track is guided and supported by sliding ledges (15, 16, 17, 18) of generally U-shaped cross section arranged in two substantially parallel tracks along supporting edges of the beam, each of said sliding ledges being split and provided with gap (19, 20) situated one on each side of the interspace between two beams, whereby one sliding ledge portion of the two longitudinally gapped portions has a flexible portion, which always entirely overlaps the interspace between the beams, and the part (21, 22) of the sliding ledge, which extends from the interspace to the gap is slidably arranged on a supporting edge of the beam on which the gap between the ledge portions is located and is fixedly arranged on a supporting edge of the other beam.
Claim 2
Dependent Claim

A conveyor incorporating a flexible conveyor track (4), guided and supported by at least two beams obliquely adjustable relative to each other and in a row one after the other with an interspace therebetween and interconnected by a pivotal link means, characterized therein, that the conveyor track is guided and supported by sliding ledges (15, 16, 17, 18) of generally U-shaped cross section arranged in two substantially parallel tracks along supporting edges of the beam, each of said sliding ledges being split and provided with gap (19, 20) situated one on each side of the interspace between two beams, whereby one sliding ledge portion of the two longitudinally gapped portions has a flexible portion, which always entirely overlaps the interspace between the beams, and the part (21, 22) of the sliding ledge, which extends from the interspace to the gap is slidably arranged on a supporting edge of the beam on which the gap between the ledge portions is located and is fixedly arranged on a supporting edge of the other beam.
Claim 3
Dependent Claim
32 words
A conveyor according to claim 1, characterized therein, that the joints (19, 20) of the sliding ledges are cut at oblique angles relative to the direction of movement for the conveyor track.
Claim 4
Dependent Claim
27 words
A conveyor according to claim 2, characterized therein, that the extension of the gaps (19, 20) converge in the normal direction of movement of the conveyor track.
