Abstract
Abstract Disclosed is an apparatus for holding a stack of papers such as paper money in a compressed state before and during the winding of a binder tape around the stack to form a bound paper bundle. The apparatus comprises first and second bases or platforms longitudinally aligned to each other with a gap interposed therebetween. Each of the platforms is in the upper surface thereof formed with an arcuately concaved longitudinal recess which is adapted to be covered by resilient plate for receiving thereon the stack of papers to be bound. Disposed above the first and second platforms is a vertically movable pressing pad plate which has an arcuately convexed lower surface. The stack of papers placed on the resilient plate can thus be clamped between the platforms and the lowered pressing pad and held in the arcuately compressed state.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
A compressing device for use in an apparatus for binding stacks of paper sheets with a binder tape, said compressing device comprising: a first platform, at least a portion of the upper surface of said first platform being arcuately concaved; a second platform longitudinally aligned with said first platform in the same plane and separated from said first platform by a gap, said second platform having at least a portion of the upper surface thereof arcuately concaved; a resilient receiving plate means connected to said second platform and extending over said concave surface portions of both of said platforms and across said gap for receiving said paper sheets thereon; and a pressure pad plate above said receiving plate means reciprocally movable toward and away from said receiving plate means, said pressure pad plate having a lower surface which is arcuately convexed.
Claim 2
Dependent Claim
