Abstract
Abstract A band-removing apparatus for taking off a band wound about a paper sheet bundle. One end portion of a paper sheet bundle brought to a band-removing section by transport means is clamped in a vertical direction by a pair of clamping members, thereby causing the paper sheet bundle to be bent downward. Part of a band is stretched over the concave portion of the bent paper sheet bundle in the form of a chord. A hooking member catches said chord portion of the band. When the hooking member holding said chord portion of the band is rotated crosswise of the transport passage, then the band is pulled off from the paper sheet bundle. The removed band is let to fall into a receptacle disposed on one lateral side of the transport passage.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
84 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section; means provided in the band-removing section to bend said paper sheet bundle around one axis thereof; means for taking off the band from the bent paper sheet bundle; and means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 2
Dependent Claim
84 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section; means provided in the band-removing section to bend said paper sheet bundle around one axis thereof; means for taking off the band from the bent paper sheet bundle; and means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 3
Dependent Claim
116 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle crosswise of one axis thereof comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section; means provided in the band-removing section which bends said paper sheet bundle around one axis thereof, thereby causing part of the wound band to be stretched over the concave portion of the bent paper sheet bundle in the form of a chord; means for taking off the band from the bent paper sheet bundle; and discharge means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 4
Dependent Claim
116 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle crosswise of one axis thereof comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section; means provided in the band-removing section which bends said paper sheet bundle around one axis thereof, thereby causing part of the wound band to be stretched over the concave portion of the bent paper sheet bundle in the form of a chord; means for taking off the band from the bent paper sheet bundle; and discharge means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 5
Dependent Claim
163 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle crosswise of one axis thereof comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section with the axis of said transported paper sheet bundle set substantially at right angles to a transport direction; bending means which is provided in the band-removing section to clamp one end portion of the paper sheet bundle and bend said bundle around said one axis, thereby causing part of the wound band to be stretched over the concave portion of the bent paper sheet bundle in the form of a chord; means for taking off the band from the bent paper sheet bundle by engaging with said part of the wound band to be stretched in the form of a chord; and discharge means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 6
Dependent Claim
163 words
A band-removing apparatus for taking off a band wound about a paper sheet bundle crosswise of one axis thereof comprising: transport means for conducting a paper sheet bundle fastened by a band through a transport passage to a band-removing section with the axis of said transported paper sheet bundle set substantially at right angles to a transport direction; bending means which is provided in the band-removing section to clamp one end portion of the paper sheet bundle and bend said bundle around said one axis, thereby causing part of the wound band to be stretched over the concave portion of the bent paper sheet bundle in the form of a chord; means for taking off the band from the bent paper sheet bundle by engaging with said part of the wound band to be stretched in the form of a chord; and discharge means for carrying the paper sheet bundle from which the band has been taken off away from the band-removing section.
Claim 7
Dependent Claim
50 words
The band-removing apparatus according to claim 1, 2 or 3, wherein the paper sheet bundle-bending means is disposed on one lateral side of the transport passage; and the band-removing means is set on the opposite lateral side of the transport passage in a state facing the paper sheet bundle-bending means.
Claim 8
Dependent Claim
32 words
The band-removing apparatus according to claim 4, further comprising a receptacle disposed on said opposite lateral side of the transport passage to receive a band taken off from the paper sheet bundle.
Claim 9
Dependent Claim
64 words
The band-removing apparatus according to claim 3, wherein the paper sheet bundle-bending means comprises a pair of clamping members which are made relatively movable in a vertical direction; one of said paired clamping members is provided with a pair of spatially arranged projections; and the other clamping member is constructed in the form of a bar, which is disposed intermediate between said paired projections.
Claim 10
Dependent Claim
49 words
The band-removing apparatus according to claim 1, 2 or 3, wherein the band-removing means comprises a hooking member which is made movable crosswise of the transport direction and whose free end portion constitutes a hook for pulling the band from the paper sheet bundle by engagement with said band.
Claim 11
Dependent Claim
33 words
The band-removing apparatus according to claim 1, 2 or 3, wherein the band-removing means comprises a knifing member whose free end portion constitutes a knifing edge for cutting the band by engagement therewith.
Claim 12
Dependent Claim

The band-removing apparatus according to claim 6, wherein the paper sheet bundle-bending means further comprises an eccentric cam for effecting the relative movement of the paired clamping members.
Claim 13
Dependent Claim
57 words
The band-removing apparatus according to claim 9, further comprising means for jointly rotating the paired clamping members of the paper sheet bundle-bending means around one vertical axis through a prescribed angle, thereby causing the paper sheet bundle to be transferred from the band-removing section to the discharge means in a state held by the paired clamping members.
Claim 14
Dependent Claim
24 words
The band-removing apparatus according to claim 8, wherein the band-removing means further comprises suction means for sucking the band cut by the knifing member.
Claim 15
Dependent Claim
