Abstract
Abstract A compact and lightweight paper refolding apparatus which fits over the top of a computer printer so as to refold the paper into a neat stack with a minimum of desk space. The refolding apparatus is designed so that the computer printout exiting web of paper can be read and refolded in the same pattern as it had been folded in the stack on the supply side of the printer. This is accomplished by use of an L-shaped member (4) having a curved guide means (14) with a receiving edge (15), receiving the leading edge of the web of paper (3) exiting from the printer (1) and guiding it upwardly through a curved path and then downwardly onto a refolding surface. Since the base of the L-shaped member (4) forms the refolding surface, which is designed to fit directly over the printer (1), additional space for the refolding apparatus is not required and the computer printout is neatly stacked in the same fold pattern as had existed in the box or stack on the supply side of the printer.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
179 words
A compact and light weight paper refolding apparatus for use with a computer type printer for refolding transversely folded webs of paper fed to said printer from a folded bundle on its supply side and exiting from said printer, which comprises: A. a horizontally disposed base; and B. a vertically projecting back portion; 1. said base of said L-shaped member fitting over the top of said printer; 2. a curved guide means suspended from said back support member and having a receiving edge for receipt of the leading edge of the paper web exiting from said printer and exiting edge curving downwardly toward the upper surface of the base of said L-shaped member; 3. a stop member at the proximal end of the upper surface of said base; 4. a receiving and refolding surface on said base extending from said stop member to the distal end of said base and of sufficient length and width to stack folds of transversely folded lengths of paper in the same fold pattern as said web of paper had in the folded stack.
Claim 2
Dependent Claim
179 words
A compact and light weight paper refolding apparatus for use with a computer type printer for refolding transversely folded webs of paper fed to said printer from a folded bundle on its supply side and exiting from said printer, which comprises: A. a horizontally disposed base; and B. a vertically projecting back portion; 1. said base of said L-shaped member fitting over the top of said printer; 2. a curved guide means suspended from said back support member and having a receiving edge for receipt of the leading edge of the paper web exiting from said printer and exiting edge curving downwardly toward the upper surface of the base of said L-shaped member; 3. a stop member at the proximal end of the upper surface of said base; 4. a receiving and refolding surface on said base extending from said stop member to the distal end of said base and of sufficient length and width to stack folds of transversely folded lengths of paper in the same fold pattern as said web of paper had in the folded stack.
Claim 3
Dependent Claim
24 words
A paper refolding apparatus, as defined in Claim 1, in which said base has a depending flange which fits over the computer type printer.
Claim 4
Dependent Claim
41 words
A paper refolding apparatus, as defined in Claim 2, in which the medial portion of said depending flange is cut away at its proximal end to allow for the web of paper to feed into and to exit from said printer.
Claim 5
Dependent Claim
34 words
A paper refolding apparatus, as defined in Claim 1, in which said base of said L-shaped member has a centrally located spline extending from said stop member to the distal end of said base.
Claim 6
Dependent Claim
30 words
A paper refolding apparatus, as defined in Claim 4, in which the centrally located spline is inclined from the proximal end upwardly to the distal end of said base member.
Claim 7
Dependent Claim
34 words
A paper refolding apparatus, as defined in Claim 1, in which said stop member is inclined from the bottom surface of the L-shaped member upwardly to the top of said vertically projecting back support.
Claim 8
Dependent Claim
45 words
A paper refolding apparatus, as defined in Claim 1, in which said vertically projecting support member contains: A. a centrally cut away portion at the top forming laterally disposed posts and B. inwardly projecting pins from said post for support of said curved guide means.
Claim 9
Dependent Claim
26 words
A paper stacking apparatus, as defined in Claim 1, which includes: A. a swinging flap pivotably mounted on said exiting edge of said curved guide means.
Claim 10
Dependent Claim
28 words
A paper refolding apparatus, as defined in Claim 6, in which the angle defined by the stop and the inclined spline of the base is an obtuse angle.
Claim 11
Dependent Claim
59 words
A paper refolding apparatus, as defined in Claim 1, in which said stop member is triangular in shape, having a base portion extending distally from the back support member and a hypotenuse inclined proximally toward the top of said support member so as to serve both as a stop member and as a guide means for said paper web.
Claim 12
Dependent Claim
42 words
A paper refolding apparatus as defined in Claim 1, fn which said base has a ledge forming a planar surface at the distal portion of said base at a lower level than the planar surface at the proximal end of said base.
Claim 13
Dependent Claim
31 words
A paper refolding apparatus, as defined in Claim 11, in which the lower planar surface includes a centrally located spline projecting from said ledge to the distal end of said base.
Claim 14
Dependent Claim
25 words
A paper refolding apparatus, as defined in Claim 12, in which the centrally located spline is inclined upwardly toward the distal end of said base.

Dependent Claim
31 words
A paper refolding apparatus, as defined in Claim 12, in which the proximal end of said spline is level with the upper planar surface at the proximal end of said base.
Claim 16
Dependent Claim
150 words
A process for refolding a paper web exiting from a computer printer upon preformed spaced fold lines in alternate directions on the base of an L-shaped refolding apparatus so as to conform with the fold lines of the stack on the supply side of said computer printer, which comprises the steps of: A. engaging the leading edge of the paper web exiting from said computer printer; B. directing said leading edge vertically and upwardly in a curved path defined by a curved member suspended from a vertical support of said L shaped refolding apparatus; C. manually manipulating said web so as to maintain the integrity of the fold lines in the web being folded in the same fold pattern as had existed in the folded stack on the supply side; and D. thereafter automatically folding the exiting web onto the stack along the preformed fold lines without further manual manipulation.
