out all of them individually solve certain problems but none of them meets the above objectives in a sacrosanct manner there is always some problem or the other the present invention brings all the above changes in a way never been done before the blade elements in the present invention are carried on a flexible member such as but not limited to a wire or a chain to keep the blades in contact with the belt throughout the same flexible member supports at least two series of blades aligned on both the sides to provide twin blade cleaning moreover all the blades have a flexible tip member which cleans the belt in normal condition but bends when it encounters a mechanical fastener or similar for understanding the invention better reference will now be made to the following preferred embodiment of the invention which is illustrated in the accompanying drawings turning first to fig1 a there is illustrated the blade scraper assembly of three blade holder assembly pairs 1 2 connected to either side of a flexible chain 3 the fig1 a shows three such pairs 1 2 on either side of the chain 3 there can be more minimum there should be one pair i e one each of a blade tip assembly 1 and a hinge assembly 2 on either side of the chain 3 since there are at least two such blade assemblies connected to both the sides of the flexible member such as chain this arrangement provides two layers of belt cleaning using a single member to carry the blades this was hitherto not achieved the fig1 b shows a back view of the assembly while fig1 c being an isometric view thereof shows in greater detail the disposition of the elements of the assembly it shows.
