Abstract
Abstract A refolding and stacking receptacle for segmented sheet material, particularly computer printout paper. The receptacle has a support for supporting a stack of the material in flat, folded condition, a guideway positioned centrally of the support for receiving the leading end of a moving web of the material fed to the receptacle in an unfolded condition, and a stop in the guideway for arresting the motion of the material on contact. This results in zig-zag folding of the web and its stacking within the receptacle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
A refolding and stacking receptacle for receiving a web of linearly-moving, reversely-foldable, segmented sheet material comprising: (a) a base member having a bottom support end and a substantially horizontal sheet support top end for supporting a stack of the material in flat-folded condition, (b) a substantially vertical guideway positioned centrally of the sheet support top end and extending downwardly therefrom for receiving the leading end of the moving web fed to the receptacle in unfolded condition, the upper end portion of the guideway being flared outwardly at its interception with the horizontal top end while retaining a major portion of the horizontal top end for supporting sheet material thereon, (c) stop means in the guideway below the sheet support top end for arresting the downward linear movement of the web, and (d) side walls extending upwardly from the outer ends of the sheet support top end substantially parallel to the plane of the guideway, (e) the linear distance from the stop means to one side wall being slightly greater than the length of one of the sheet material segments and the distance between the side walls being slightly greater than the length of one of the sheet material segments, to insure accommodation of the sheet material in flat-folded condition on the sheet support top end within the side walls.
Claim 2
Dependent Claim
219 words
A refolding and stacking receptacle for receiving a web of linearly-moving, reversely-foldable, segmented sheet material comprising: (a) a base member having a bottom support end and a substantially horizontal sheet support top end for supporting a stack of the material in flat-folded condition, (b) a substantially vertical guideway positioned centrally of the sheet support top end and extending downwardly therefrom for receiving the leading end of the moving web fed to the receptacle in unfolded condition, the upper end portion of the guideway being flared outwardly at its interception with the horizontal top end while retaining a major portion of the horizontal top end for supporting sheet material thereon, (c) stop means in the guideway below the sheet support top end for arresting the downward linear movement of the web, and (d) side walls extending upwardly from the outer ends of the sheet support top end substantially parallel to the plane of the guideway, (e) the linear distance from the stop means to one side wall being slightly greater than the length of one of the sheet material segments and the distance between the side walls being slightly greater than the length of one of the sheet material segments, to insure accommodation of the sheet material in flat-folded condition on the sheet support top end within the side walls.
Claim 3
Dependent Claim
184 words
A refolding and stacking receptacle for receiving the web of linearly-moving, reversely-foldable, segmented sheet material comprising: (a) a base member having a bottom support end and a substantially horizontal sheet support top end for supporting a stack of the material in flat-folded condition, (b) a substantially vertical guideway positioned centrally of the sheet support top end and extending downwardly therefrom for receiving the leading end of the moving web fed to the receptacle in unfolded condition, (c) stop means in the guideway below the sheet support top end for arresting the downward linear movement of the web, (d) side walls extending upwardly from the outer ends of the sheet support top end substantially parallel to the plane of the guideway, (e) the linear distance from the stop means to one side wall being slightly greater than the length of one of the sheet material segments to insure accommodation of the sheet material in flat-folded condition on the sheet support top end within the side walls, and (f) an upper web-receiving guideway positioned a spaced distance above and substantially aligned vertically with the lower guideway.
Claim 4
Dependent Claim
184 words
A refolding and stacking receptacle for receiving the web of linearly-moving, reversely-foldable, segmented sheet material comprising: (a) a base member having a bottom support end and a substantially horizontal sheet support top end for supporting a stack of the material in flat-folded condition, (b) a substantially vertical guideway positioned centrally of the sheet support top end and extending downwardly therefrom for receiving the leading end of the moving web fed to the receptacle in unfolded condition, (c) stop means in the guideway below the sheet support top end for arresting the downward linear movement of the web, (d) side walls extending upwardly from the outer ends of the sheet support top end substantially parallel to the plane of the guideway, (e) the linear distance from the stop means to one side wall being slightly greater than the length of one of the sheet material segments to insure accommodation of the sheet material in flat-folded condition on the sheet support top end within the side walls, and (f) an upper web-receiving guideway positioned a spaced distance above and substantially aligned vertically with the lower guideway.
Claim 5
Dependent Claim
16 words
The receptacle of claim 2 wherein the upper guideway comprises an aperture V-shaped in cross section.
Claim 6
Dependent Claim
47 words
The receptacle of claim 2 wherein the upper guideway comprises an aperture V-shaped in cross section, the guiding surfaces of the upper guideway including a plurality of spaced ribs positioned in the direction of material flow to reduce development of static electricity during filling of the receptacle.
Claim 7
Dependent Claim
31 words
The receptacle of claim 2 wherein the upper guideway comprises an upper base supported by the side walls and defining a web-receiving aperture therethrough substantially aligned vertically with the lower guideway.
