Abstract

A ribbon assembly including face-to-face bow ribbons attached together at spaced locations around a pull member attached to their ends that can be pulled to gather the bow ribbons into a bow. Upon such pulling an end portion of the assembly is pulled between the attachment locations to hold the bow ribbons together in the shape of a bow.

Claims8

Dependent claims

A ribbon assembly adapted to be formed into a bow, said ribbon assembly comprising:

a pull member of a first width and having a first end;
a pair of elongate bow ribbons having first ends generally aligned with the first end of said pull member, being attached to said pull member at a location adjacent said first ends, having a width wider than said first width, being disposed on opposite sides of said pull member with edge portions of said bow ribbons extending past the adjacent edges of said pull member on both sides, being attached together at spaced attachment locations along said edge portions including a first set of opposite attachment locations spaced a predetermined distance from said first ends and a second set of generally opposite attachment locations adjacent the ends of said bow ribbons opposite said first ends, and having end portions adjacent said first ends which end portions have edge surfaces with portions spaced at a distance corresponding to the spacing between said first set of attachment locations and parts projecting beyond said edge surface portions of a width adapted to move between said attachment locations so that when said bow ribbons are held adjacent said second set of attachment locations and said pull member is pulled to move said first ends toward and through said first set of attachment locations, said attachment locations will gather adjacent each other, portions of said bow ribbons between said attachment locations and between said attachment locations and said end portions will billow outwardly to form a bow, said edge surface portions on the end portions of said bow ribbons will engage and be stopped by said first set of attachment locations, and said parts of said end portions will pass and extend between said first attachment locations;
and
self-locking means adapted to be pulled to a position on the side of said second set of attachment locations opposite said first set of attachment locations upon formation of said bow, which self-locking means will resist movement back through said second set of attachment locations to hold said attachment locations adjacent each other and retain the shape of said bow.
