Abstract
Abstract A conveyor comprising an endless band which constitutes a moving track and a plurality of adjacent open-topped foldable transporting members secured with their respective bottom portions to the endless band. The transporting members are arranged so that adjoining wall sections of adjacent transporting members are secured to each other and extend at least in the region of these adjoining wall sections at an acute angle relative to the endless band and in direction of movement thereof.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
137 words
A conveyor comprising, in combination, an elongated endless band constituting a moving track; and a plurality of individual, adjacent open-topped, pocket-shaped transporting members having each a pair of opposite walls extending transverse to the elongation of said band and having spaced from said band free transverse edges, a pair of opposite sidewalls integrally connecting said transverse walls at opposite sides to each other, and a bottom wall secured to said endless band and integrally connecting said transverse and sidewalls to each other, adjacent transporting members being directly connected to each other only at said free transverse edges of said transverse walls, and said transverse walls of said transporting members extending at least in the region adjacent to said free transverse edges at an acute angle relative to said endless band and in the direction of movement thereof.
Claim 2
Dependent Claim
137 words
A conveyor comprising, in combination, an elongated endless band constituting a moving track; and a plurality of individual, adjacent open-topped, pocket-shaped transporting members having each a pair of opposite walls extending transverse to the elongation of said band and having spaced from said band free transverse edges, a pair of opposite sidewalls integrally connecting said transverse walls at opposite sides to each other, and a bottom wall secured to said endless band and integrally connecting said transverse and sidewalls to each other, adjacent transporting members being directly connected to each other only at said free transverse edges of said transverse walls, and said transverse walls of said transporting members extending at least in the region adjacent to said free transverse edges at an acute angle relative to said endless band and in the direction of movement thereof.
Claim 3
Dependent Claim
29 words
A conveyor as defined in claim 1, wherein said sidewalls are provided with folds inclined substantially in the same direction relative to said endless band as said transverse wall.
Claim 4
Dependent Claim
21 words
A conveyor as defined in claim 1, wherein said transporting members are substantially rectangular and have a substantially U-shaped cross section.
Claim 5
Dependent Claim
31 words
A conveyor as defined in claim 1, wherein said opposite sidewalls extend in a planes coincident with the elongation of said endless band and foldable in the direction of movement thereof.
Claim 6
Dependent Claim
17 words
A conveyor as defined in claim 1, wherein said transporting members are made of an elastomeric material.
Claim 7
Dependent Claim
26 words
A conveyor as defined in claim 1, wherein said bottom walls of said transporting members are secured to said endless band by means of screw members.
Claim 8
Dependent Claim
47 words
A conveyor as defined in claim 1, wherein said bottom walls of said transporting members are secured to said endless band by means of screw members, and wherein said bottom walls at axially opposite ends thereof have bores defined therethrough for the passage of said screw members.
Claim 9
Dependent Claim
21 words
A conveyor as defined in claim 1, wherein said bottom walls of said transporting members are vulcanized to said endless band.
Claim 10
Dependent Claim
26 words
A conveyor as defined in claim 1, wherein said bottom walls of said transporting members are connected to said endless band by means of an adhesive.
Claim 11
Dependent Claim
25 words
A conveyor as defined in claim 1, wherein said transverse free edges of said transverse walls of adjacent transporting members are bonded to each other.
Claim 12
Dependent Claim
29 words
A conveyor as defined claim 1, wherein said transverse free edges of said transverse walls of adjacent transporting members are secured to each other by means of an adhesive.
Claim 13
Dependent Claim
