Abstract

A width folder is configured for width-folding an article of laundry, and especially lateral excess portions thereof. The width folder includes male and female members stacked along a vertical direction. The male member includes two opposite first folding edges which extend along a laundry article motion direction perpendicular to the vertical direction and further includes opposite male top and bottom surfaces each of which extends between the first folding edges. The female member being located at least partially beneath the male member and includes two opposite second folding edges which converge in the motion direction. The female member further includes opposite female top and bottom surfaces. The female member further includes opposite folding protrusions which extend outwardly therefrom in a direction away from the female top surface.

First claim

The invention claimed is:

1. A width-folding system, or width folder ( 20 ), configured for width-folding an article of laundry ( 58 ), and especially excess portions thereof, the width folder ( 20 ) comprising male and female members ( 26 , 28 ) stacked along a vertical direction (VD);
the male member ( 26 ) comprising two opposite first folding edges ( 34 ) extending at least partially along a laundry article motion direction (MD) perpendicular to the vertical direction (VD) and comprising opposite male top and bottom surfaces ( 30 , 32 ) each extending between the first folding edges ( 34 ); and
the female member ( 28 ) being located at least partially beneath the male member ( 26 ) and comprising two opposite second folding edges ( 48 ) converging inwards along the motion direction (MD); the female member ( 28 ) further comprising opposite female top and bottom surfaces ( 42 , 44 ); in a plan view of the width folder ( 20 ) along the vertical direction (VD), each second folding edge ( 48 ) intersecting a respective adjacent first folding edge ( 34 );

wherein
the female member ( 28 ) further comprises opposite folding protrusions ( 54 ) which extend outwardly therefrom in a direction away from the female top surface ( 42 ) and configured to urge inwards, in the width-direction (WD), excess fabric, or extremities, of the laundry article ( 58 ) while it proceeds across the male top surface ( 30 ); and

wherein the male member ( 26 ) further comprises a sloping portion extending downwards, beneath the male top surface ( 30 ), along the vertical direction (VD), and in a direction opposite the motion direction (MD).

2. The width folder ( 20 ) according to claim 1 , wherein the female and male members are permanently and rigidly connected to one another.

3. The width folder ( 20 ) according to claim 1 , wherein the folding protrusions ( 54 ) have a rectilinear blade shape in a view along a width direction (WD) which is perpendicular to the motion direction (MD) and the vertical direction (VD).

4. The width folder ( 20 ) according to claim 1 , wherein the folding protrusions ( 54 ) have a thin shape which extends parallel to the vertical direction (VD).

5. The width folder ( 20 ) according to claim 1 , wherein the folding protrusions ( 54 ) extend beyond the male member in the vertical direction (VD) away from the female top surface ( 42 ).

6. The width folder ( 20 ) according to claim 1 , wherein the folding protrusions ( 54 ) extend from the female top surface ( 42 ).

7. The width folder ( 20 ) according to claim 1 , wherein each folding protrusion ( 54 ) extends from a respective end of the respective second folding edges ( 48 ).

8. The width folder ( 20 ) according to claim 1 , wherein the width-folder comprises exactly two folding protrusions ( 54 ).

9. The width folder ( 20 ) according to claim 1 , wherein the male top surface ( 30 ) comprises two opposite parallel grooves ( 24 ) which open out thereto.

10. The width folder ( 20 ) according to claim 1 , wherein in a top view of the width folder ( 20 ), tangent lines to each of the first folding edges ( 34 ) converge in a direction opposite the motion direction (MD).

11. The width folder ( 20 ) according to claim 1 , wherein in a bottom view of the width folder ( 20 ), tangent lines to each of the second folding edges ( 48 ) converge in the motion direction (MD).

12. The width folder ( 20 ) according to claim 1 , wherein each second folding edge ( 48 ) has a folding edge recess ( 56 ) which is configured to improve fold formation, locating the fold and for repeatability for long extremities, and especially long sleeves.

13. A method of width-folding excess portions of an article of laundry ( 58 ) comprising the following steps:
a. providing the width folder ( 20 ) according to claim 1 ;
b. pulling the article ( 58 ) across male top surface ( 30 ) in the motion direction (MD) while excess extremities of the article ( 58 ) hang respectively over the first folding edges ( 34 );
c. pulling the article ( 58 ) further while the excess extremities of the article ( 58 ) climb on the folding protrusions ( 54 ) and urged inwardly in the width direction (WD).
