Abstract
Abstract Herein disclosed is a sheet binding apparatus wherein sheets such as bank notes are wound by tape and bound into a bundle of sheets by fusing and cutting the tape. The apparatus is provided with a pair of holding plates, each formed with a notch groove through which the tape is passed. The holding plates which hold the sheets therebetween are horizontally moved to a binding section while a tape is passed through one of the notch groove of one holding plate. At the binding section, a tape push-down member pushes down the tape through the other notch groove of the other holding plate to wind the sheets. The tape push-down member is formed at the lower end thereof with a forked portion for providing a recess. A heating member having a convex surface for engaging with the tape is disposed below the recess of the tape push-down member. The tape is heated and cut off while it is sandwiched between the tape push-down member and the heating member. A tension imparting mechanism is provided for imparting a tension to the tape. A plurality of position detecting sensors are provided for detecting the various positions of the tape push-down member and issuing signals for commanding various operations.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
318 words
An apparatus for binding sheets by a tape which comprises: a supporting plate for supporting thereon sheets to be bound; a pair of confronting holding plates disposed above the supporting plate and horizontally movable between one position where the sheets are set between said holding plates and another position where the sheets are bound, each holding plate being formed on the inner surface thereof with a notch groove; means for supplying the tape to said holding plates; means for horizontally moving the holding plates to clamp the sheets therebetween while the tape is received in one notch groove of one holding plate between said one holding plate and the sheets to cover the sheets at top and bottom edges thereof with the tape; a tape push-down member disposed above the pair of holding plates and movable vertically to push the tape into the groove of the other holding plate between said other holding plate and the sheets whereby the sheets are wrapped with the tape, the tape push-down member being formed at its lower end with a forked portion in which a recess is formed; a heating member for bonding the ends of the wrapped tape and cutting the tape to separate the end of the wrapped tape from the supplied end of the tape, the heating member being disposed below the recess of the tape push-down member and having a convex surface for engaging with the tape to bond and cut the tape; and means for limiting the movement of said tape push-down member when said tape push-down member is engaged with the tape under tension and is imparted a great amount of reaction by the tape, said limting means comprising a friction plate and a pair of gears for frictionally engaging the friction plate therebetween, one of the gears being driven by a driving source and the other of the gears driving the tape push-down member.
