Abstract
Abstract A paper web forming apparatus essentially comprising two wires adapted to move together with stock material which is held therebetween and wire supporting members for supporting the wires, each of the wire supporting members including a wedge-shaped space as defined between the wire surface and the wire supporting member. wherein the wedge-shaped space is so designed that the width as measured therebetween decreases as seen in the direction of movement of the wires.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
72 words
A paper web forming apparatus essentially comprising two wires adapted to move together with stock material which is held therebetween and wire supporting members for supporting said wires, each of said wire supporting members including a wedge-shaned space as defined between the wire surface and the wire supporting member, said wedge-shaped snace being so formed that the width as measured therebetween decreases as seen in the direction of movement of the wires.
Claim 2
Dependent Claim
72 words
A paper web forming apparatus essentially comprising two wires adapted to move together with stock material which is held therebetween and wire supporting members for supporting said wires, each of said wire supporting members including a wedge-shaned space as defined between the wire surface and the wire supporting member, said wedge-shaped snace being so formed that the width as measured therebetween decreases as seen in the direction of movement of the wires.
Claim 3
Dependent Claim
26 words
A paper web forming apparatus as defined in claim 1, wherein the wire supporting members are alternately arranged on both the sides of the two wires.
Claim 4
Dependent Claim
42 words
A paper web forming apparatus as defined in claims 1 and 2, wherein the rear end of each of the wire supporting members is pushed in relative to the wire line of each of the two wires by a very short distance.
Claim 5
Dependent Claim
70 words
A paper web forming apparatus as defined in claims 1 to 3, wherein each of the wire supporting members comprises a formation foil which is fixedly disposed at a predetermined inclination angle relative to the moving wires, the rear end of said formation foil coming in contact with the wires to support the latter,whereby a wedge-shaped space having an apex at the contact point is formed on the wire surface.
