Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A blade guide for saw blades, comprising a number of small cemented carbide plates (2) which are moulded at intervals onto a base plate (1) of steel or the like by means of a metal (3) which is considerably softer than the carbide in the plates (2), said base plate having an upturned peripheral edge extending for substantially the thickness of the carbide plate thereby forming a dish-like structure, and said small cemented carbide plates being adjacent said base plate on the interior of the dished configuration.
Claim 2
Dependent Claim
87 words
A blade guide for saw blades, comprising a number of small cemented carbide plates (2) which are moulded at intervals onto a base plate (1) of steel or the like by means of a metal (3) which is considerably softer than the carbide in the plates (2), said base plate having an upturned peripheral edge extending for substantially the thickness of the carbide plate thereby forming a dish-like structure, and said small cemented carbide plates being adjacent said base plate on the interior of the dished configuration.
Claim 3
Dependent Claim
65 words
A blade guide for saw blades, comprising a number of small cemented carbide plates (2) which are moulded at intervals onto a base plate (1) of steel or the like by means of a metal (3) which is considerably softer than the carbide in the plates (2), the carbide plates 2 each comprising a frustoconical cross-section having a base thereof facing the base plate (1).
Claim 4
Dependent Claim
65 words
A blade guide for saw blades, comprising a number of small cemented carbide plates (2) which are moulded at intervals onto a base plate (1) of steel or the like by means of a metal (3) which is considerably softer than the carbide in the plates (2), the carbide plates 2 each comprising a frustoconical cross-section having a base thereof facing the base plate (1).
Claim 5
Dependent Claim
31 words
A blade guide as claimed in claim 1 or 2, wherein the base plate (1) is round, the carbide plates (2) being disposed along the periphery of the base plate (1).
Claim 6
Dependent Claim
23 words
A blade guide as claimed in claim 1 or 2, wherein said metal is selected from the group consisting of brass and bronze.
Claim 7
Dependent Claim
23 words
A blade guide as claimed in claim 3 having an annular configuration thereby defining a central hole (4) serving as a water-cooling channel.
Claim 8
Dependent Claim
27 words
A blade guide as claimed in claim 1 or 2, wherein the surface area of the soft metal exceeds the surface area of the cemented carbide plates.
