Abstract
Abstract A scalloped stream of paper sheets is intermittently transported from a feeding unit to a reservoir wherein one portion of a flexible elastic band convolutes the sheets around a core. The sheets are then transported over a switchover device and onto another portion of the band which convolutes the sheets around a hub while the core pays out the one portion of the band. If the sheets are needed at one or more consuming stations, the hub pays out the other portion of the band and the switchover device directs successive sheets from the other portion of the band to a removing unit. The switchover device and the one portion of the band define a first station where the sheets arriving from the feeding unit reach the one portion of the band and where the sheets leave the one portion of the band on their way to the other portion of the band. The other portion of the band and the switchover device define a second transfer station. The elasticity of the band is such that its length is increased by at least 0.1% in response to the application of a tensional stress of at least 0.25 kg/mm 2 .

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
In an apparatus for manipulating paper sheets and the like, sheet feeding means; and sheet stacking means including a rotary hub, an elongated elastic flexible element arranged to receive sheets from said feeding means and having an end portion secured to said hub, and means for rotating said hub at least in a direction to convolute the flexible element around the hub so that the sheets which are supplied by said feeding means are confined between the resulting convolutions of said flexible element, the elasticity of said flexible element being such that its length is increased by at least one-tenth of one percent in response to the application of a tensional stress of at least 0.5 kg/mm 2 .
Claim 2
Dependent Claim
119 words

Claim 3
Dependent Claim
45 words
The structure of claim 1, wherein the elasticity of said flexible element is such that its length is increased by between 0.5 and 1 percent in response to the application of a tensional stress in the order of between 0.5 and 1.5 kg/mm 2 .
Claim 4
Dependent Claim
41 words
The structure of claim 1, wherein the elasticity of said flexible element is such that its length is increased by at least one-tenth of one percent in response to the application of a tensional stress of approximately 1 kg/mm 2 .
Claim 5
Dependent Claim
20 words
The structure of claim 1, wherein said sheet feeding means includes means for continuously feeding sheets to said flexible element.
Claim 6
Independent Claim
113 words
A method of manipulating paper sheets and the like, comprising the steps of feeding a succession of sheets along a first path; conveying an elastic flexible element along a second path a portion of which is closely adjacent a portion of said first path so that the sheets of said succession are transferred onto the flexible element, the elasticity of the flexible element being such that its length is increased by at least one percent in response to the application of a tensional stress of at least 0.5 kg/mm 2 ; and convoluting the flexible element around a core so that the sheets are confined between the resulting convolutions of the flexible element.
Claim 7
Independent Claim
113 words
A method of manipulating paper sheets and the like, comprising the steps of feeding a succession of sheets along a first path; conveying an elastic flexible element along a second path a portion of which is closely adjacent a portion of said first path so that the sheets of said succession are transferred onto the flexible element, the elasticity of the flexible element being such that its length is increased by at least one percent in response to the application of a tensional stress of at least 0.5 kg/mm 2 ; and convoluting the flexible element around a core so that the sheets are confined between the resulting convolutions of the flexible element.
Claim 8
Dependent Claim
45 words
The method of claim 5, wherein the elasticity of the flexible element is such that its length is increased by between 0.5 and 1 percent in response to the application of a tensional stress in the order of between 0.5 and 1.5 kg/mm 2 .
Claim 9
Dependent Claim
33 words
The method of claim 5, wherein the tensional stress at which the lengthh of the elastic flexible element is increased by at least one-tenth of one percent is approximately 1 kg/mm 2 .
Claim 10
Dependent Claim
25 words
The method of claim 5, wherein said feeding step includes continuously feeding sheets of said succession along said first path and onto the flexible element.
Claim 11
Dependent Claim
14 words
The method of claim 5, wherein said convoluting step includes tensioning the flexible element.
