Abstract
Abstract A combined document bundling and banding machine is described in which documents are fed one by one into a banding station to form a stack or bundle of documents, the bundle of documents are urged across the path of a continuous banding strip extending across the banding station such that a portion of the strip is deflected out of its path around the front of the bundle, and the strip is reunited along the path at the rear of the bundle so that the resulting overlapped portions of the strip can be bonded to one another.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
A document banding machine for banding a sequence of documents comprising a rotatable vacuum drum for feeding the documents one by one into a banding station to form a stack or bundle of documents, a continuous banding strip extending across the banding station, a device movable from a first position in which the device peels documents away from the periphery of the vacuum drum to a second position in which the device holds the bundle of documents against a rigid backing member, an acutator for moving the device from its first position to its second position after a predetermined number of documents have been stripped from the drum, the movement of the device urging the bundle of documents across the path of the continuous banding strip such that a portion Of the strip is deflected out of its path around the front of the bundle, a reciprocating guide member movable from a first position to a second position to guide the strip around the back of the bundle and to reunite the strip along the path, and a bonding device for bonding the resulting overlapped portions of the strip to one another.
Claim 2
Dependent Claim
192 words
A document banding machine for banding a sequence of documents comprising a rotatable vacuum drum for feeding the documents one by one into a banding station to form a stack or bundle of documents, a continuous banding strip extending across the banding station, a device movable from a first position in which the device peels documents away from the periphery of the vacuum drum to a second position in which the device holds the bundle of documents against a rigid backing member, an acutator for moving the device from its first position to its second position after a predetermined number of documents have been stripped from the drum, the movement of the device urging the bundle of documents across the path of the continuous banding strip such that a portion Of the strip is deflected out of its path around the front of the bundle, a reciprocating guide member movable from a first position to a second position to guide the strip around the back of the bundle and to reunite the strip along the path, and a bonding device for bonding the resulting overlapped portions of the strip to one another.
Claim 3
Dependent Claim
52 words
A document banding machine according to claim 1, in which the rigid backing member includes a straight centre section, the device including means for curving the bundle about the centre section of the backing member prior to the movement of the reciprocating guide member from its first position to its second position.
Claim 4
Dependent Claim
60 words
A document banding machine according to claim 1, in which the bonding device includes a pair of RF electrodes one of which is carried by the guide member such that movement of the guide from its first position to its second position simultaneously compresses the overlapped portions of the banding strip between the two electrodes to permit RF welding thereof.
Claim 5
Dependent Claim
66 words
A document banding machine according to claim 1, in which the continuous banding strip is elastic and in which the banding machine includes a continuous pull-down mechanism such that the banding strip is stretched across the banding station during the banding operation whereby the subsequent relaxation of the banding strip after the overlap portions have been bonded to one another tightens the strip around the bundle.
Claim 6
Dependent Claim
37 words
A document banding machine according to claim 3, in which one of the electrodes includes a blade such that the joint between the over lapped portions is at least partially severed during welding to form a tear-seal.
