Abstract

Abstract A system for assisting in removing broke from a paper or board making machine includes an elongated cylindrical member mounted on an obstruction extending transversely beneath the paper or board making machine. The elongated member can be rotated to move the broke, hung up on the obstruction, off the obstruction in order to clear the machine.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 163 words
A system for removing broke from an obstruction member extending across a paper or board machine and located beneath the path of travel of a web through the machine, said system including at lEast one elongated cylindrical member for moving the broke, and shaft means extending axially from said elongated cylindrical member to rotatably mount said elongated cylindrical means, the outer surface of said elongated cylindrical member comprising a row of spaced-apart spikes, means for rotatably mounting said elongated cylindrical member on the obstruction member so that the cylindrical member extends transversely substantially across the width of the machine, said means for rotatably mounting said elongated cylindrical member comprising brackets on the obstruction member for receiving the shaft means extending from the elongated cylindrical member, the shaft means extending from said elongated cylindrical member extending substantially parallel to the longitudinal axis of the obstruction, whereby the elongated cylindrical member is adapted to move broke draped thereover as the elongated cylindrical member is rotated.
Claim 2
Independent Claim 163 words
A system for removing broke from an obstruction member extending across a paper or board machine and located beneath the path of travel of a web through the machine, said system including at lEast one elongated cylindrical member for moving the broke, and shaft means extending axially from said elongated cylindrical member to rotatably mount said elongated cylindrical means, the outer surface of said elongated cylindrical member comprising a row of spaced-apart spikes, means for rotatably mounting said elongated cylindrical member on the obstruction member so that the cylindrical member extends transversely substantially across the width of the machine, said means for rotatably mounting said elongated cylindrical member comprising brackets on the obstruction member for receiving the shaft means extending from the elongated cylindrical member, the shaft means extending from said elongated cylindrical member extending substantially parallel to the longitudinal axis of the obstruction, whereby the elongated cylindrical member is adapted to move broke draped thereover as the elongated cylindrical member is rotated.
Claim 3
Dependent Claim 27 words
A system as defined in claim 1, wherein said obstruction member comprises a web conditioning nozzle, and wherein said brackets are mounted on said web conditioning nozzle.
Claim 4
Dependent Claim 16 words
A system as defined in claim 1, wherein the outer surface comprises two rows of spikes.
Claim 5
Dependent Claim 43 words
A system as claimed in claim 1, wherein the means for rotating said cylindrical member comprises a motor, drive means connecting the motor to the shaft extending from the cylindrical member and means for operating the motor to selectively rotate the cylindrical member.
