Abstract
Abstract The separation of a small multiplicity of sheets from a bale of pulp is carried out by shearing the sheets from the body of the bale and feeding the separated sheets from the equipment. The separating equipment in a preferred embodiment includes a pulp sheet separator in the general form of a blade which penetrates the bale in a zone adjacent an upper side of the bale while the bale itself is moving upwardly. The separator is hingedly mounted to protect it against breakage and to permit jogging of the blade. The separator blade is, in operation, capable of being jogged in a plane perpendicular to its own plane while inserted in the bale to aid in breaking pulp sheets from the body of the bale. The action of the separator and bale moving mechanism may be substantially continuous until the last sheets of the bale have been severed and moved from the separator equipment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, a mounting for the said carrier means, other means pivotally supporting the pulp sheet separator with respect to said carrier means so that said pulp sheet separator may be jogged in a direction transverse to the plane of the pulp sheet separator to break pulp sheets loose from a pulp bale into which the separator has penetrated, and fourth means for jogging the pulp sheet separator when the pulp sheet separator is over the elevator, said fourth means being upwardly inclined cam means on the mounting positioned to be traversed by the carrier means in said movement of the carrier means.
Claim 2
Dependent Claim
173 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, a mounting for the said carrier means, other means pivotally supporting the pulp sheet separator with respect to said carrier means so that said pulp sheet separator may be jogged in a direction transverse to the plane of the pulp sheet separator to break pulp sheets loose from a pulp bale into which the separator has penetrated, and fourth means for jogging the pulp sheet separator when the pulp sheet separator is over the elevator, said fourth means being upwardly inclined cam means on the mounting positioned to be traversed by the carrier means in said movement of the carrier means.
Claim 3
Dependent Claim
173 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, a mounting for the said carrier means, other means pivotally supporting the pulp sheet separator with respect to said carrier means so that said pulp sheet separator may be jogged in a direction transverse to the plane of the pulp sheet separator to break pulp sheets loose from a pulp bale into which the separator has penetrated, and fourth means for jogging the pulp sheet separator when the pulp sheet separator is over the elevator, said fourth means being upwardly inclined cam means on the mounting positioned to be traversed by the carrier means in said movement of the carrier means.
Claim 4
Dependent Claim
173 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, a mounting for the said carrier means, other means pivotally supporting the pulp sheet separator with respect to said carrier means so that said pulp sheet separator may be jogged in a direction transverse to the plane of the pulp sheet separator to break pulp sheets loose from a pulp bale into which the separator has penetrated, and fourth means for jogging the pulp sheet separator when the pulp sheet separator is over the elevator, said fourth means being upwardly inclined cam means on the mounting positioned to be traversed by the carrier means in said movement of the carrier means.
Claim 5
Dependent Claim
126 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, said elevator having a platform for the bale and a plurality of supports in spaced relation forming the platform, finger means between some of said supports and normally positioned below the platform level, and means for urging the finger means upwardly above the platform level to urge a pulp bale on the platform upwardly.
Claim 6
Dependent Claim
126 words
In apparatus for separating sheets of pulp from a pulp bale, an elevator for raising a bale of pulp, lateral support means for a bale of pulp carried on the elevator, a pulp sheet separator, carrier means supporting the pulp sheet separator for movement transversely across and above the elevator in the direction of the said lateral support means and through a bale on the elevator to remove sheets from the bale, said elevator having a platform for the bale and a plurality of supports in spaced relation forming the platform, finger means between some of said supports and normally positioned below the platform level, and means for urging the finger means upwardly above the platform level to urge a pulp bale on the platform upwardly.
Claim 7
Dependent Claim
22 words
In apparatus for separating sheets of pulp from a pulp bale as claimed in claim 2 in which the supports are rollers.
Claim 8
Dependent Claim
106 words
In apparatus for separating sheets of pulp from a pulp bale as claimed in claim 2 wherein the means for urging the finger means upwardly include lever means operatively associated with the finger means for moving the finger means upwardly above the platform level, said lever means projecting laterally of the elevator, and a contactor abutment fixedly positioned in the path of the projecting lever means arranged to engage the lever means at the upper end of the elevator movement to raise the finger means upwardly and lift the lowermost sheets of a bale on the elevator platform for movement of the pulp sheet separator thereunder.
Claim 9
Independent Claim
120 words
The method of separating a plurality of pulp sheets from a bale of pulp sheets comprising the steps of moving a bale of the pulp continuously upwardly, penetrating the bale with a relatively wide pulp separator by urging the separator substantially horizontally into the bale, and then when the separator is within the bale jogging the separator in a vertical direction to break the upper pulp sheets loose from the bale, and then removing the loosened sheets from the bale, the said method including that the lowermost sheets of the bale, following removal of the upper sheets, are raised on an edge facing the pulp separator to permit the pulp separator to pass beneath the lowermost sheets of the bale
Claim 10
Independent Claim
120 words
