Abstract

An apparatus and method for automatically wrapping at least one eating utensil in a napkin includes a receiving area for at least one utensil and at least one napkin, and a mechanism for automatically wrapping. The mechanism for automatically wrapping includes a frame, a flexible belt disposed in the frame, and a belt manipulation device. The belt has a first surface adapted for frictional contact with the napkin. At least a portion of the belt is movable to form a trough in which the napkin and utensil are manipulated and urged by frictional contact with the belt to fold and roll, automatically wrapping the utensil.

Claims

1. A method for automatically wrapping a plurality of differently shaped, substantially rigid utensils with a napkin into a non-airtight bundle, said napkin having one surface including first and second side portions and a central portion therebetween, said method comprising the steps of:

positioning a plurality of differently shaped, substantially rigid utensils and at least one napkin in a receiving area wherein said step of positioning includes positioning said utensils in at least one of said portions of said napkins;

manipulating said at least one napkin and said plurality of utensils with an automatic wrapping mechanism, wherein said step of manipulating automatically includes;

generally surrounding said plurality of utensils with said at least one napkin wherein said step of generally surrounding includes automatically folding at least part of one of said portions over said utensils so as to be positioned opposite to and in contact with a part of another of said portions;

forming a variably shaped, non-airtight bundle of substantially rigid utensils of different shapes, said bundle including an open central structure retained by said at least one napkin;

whereby said utensils are prepared for use generally surrounded by at least one napkin.

2. The method of claim 1 wherein:

said step of automatically folding includes folding parts of said side portions into generally opposing relationship, and positioning said utensils generally within said central portion; and

said step of forming comprises wrapping said opposing side portions in unison generally around said central portion and utensils therein.

3. The method of claim 1 wherein:

said step of positioning includes positioning said utensils in one of said side portions of said napkin; and

said step of forming includes automatically wrapping said napkin generally around said utensils, beginning approximately at a first side portion and continuing to the other side portion.

4. The method of claim 1 wherein one surface of said napkin includes first and second side portions and a central portion therebetween, and wherein said step of manipulating includes tucking inward an edge of said central portion of said napkin.

5. The method of claim 1 wherein said automatic wrapping mechanism includes at least one flexible belt having a movable portion, and wherein:

said step of positioning is performed on a portion of at least one flexible belt which portion is defined as said receiving area; and

said step of manipulating is performed automatically by;

frictionally engaging at least a portion of said napkin with a movable portion of said belt; and

thereafter, performing said steps of generally surrounding and forming a non-airtight bundle by moving said movable portion of said belt.

6. The method of claim 5 wherein:

said step of manipulating is performed automatically by

initially restraining a portion of said napkin in said receiving area.

7. The method of claim 1 further including the step of automatically securing said napkin with a band around the outer surface of said bundle.
