Abstract
Abstract The invention relates to a conveyor belt with wire members hinged to one another by means of bars. The members consist of individual chain links which are arranged in succession, transversally to the longitudinal (conveying) direction of the belt, with their longitudinal extension in the longitudinal direction of the belt parallel to and at a distance from one another which is somewhat greater than the thickness of a chain link, and are connected to one another by at least one continuous welded seam.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
Conveyor belt formed from individual chain links which are arranged with their longitudinal extension in the longitudinal direction of the belt to form members parallel to and at a distance from one another, said chain links are formed from a piece of wire bent such that one end of the wire is adjacent to the other end of the wire with a gap between each end, the chain links of the adjacent members being inserted partially into one another and being hinged to one another by means of bars inserted through the aligned orifices, wherein the chain links forming the belt members are arranged in succession, transversally to the longitudinal direction of the belt, at a parallel distance from one another, which is somewhat greater than the thickness of a chain link, and are connected to one another by at least one continuous welded seam laid so that it closes the gap of the wire forming the chain link.
Claim 2
Dependent Claim
159 words

Claim 3
Dependent Claim
14 words
A conveyor belt according to claim 1, wherein said wire has a round profile.
Claim 4
Dependent Claim
25 words
A conveyor belt according to claim 1, wherein each bar is widened at its ends so that the bar cannot slip out from the links.
