Abstract
Abstract Apparatus for mechanically fabricating prefabricated bow forms from two strips of decorative ribbon material and including a drawstring partially bonded to the ribbon, said apparatus comprising a ribbon and drawstring supply, motor means, a ribbon bonding assembly for bonding said ribbon materials together at spaced points, a ribbon advancing means and a ribbon cutoff means. A simple method of forming decorative bows from the prefabricated bow forms is also disclosed, said method comprising accumulating the bonded areas of said prefabricated bow forms one upon another, simultaneously forming loops of ribbon on either side of said bonded areas, by means of the drawstring.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A prefabricated bow form for a formal bow formed from two lengths of ribbon and a drawstring, said ribbons being in superimposed back to back relationship with said drawstring centrally interposed therebetween, said ribbons and drawstring being firmly bonded together at a first bonded narrow elongate rectangular area at one end of said bow form, said ribbons being bonded together in a narrow elongate segmented rectangular bond at at least two other spaced points along the length of the composite of ribbon and drawstring, said drawstring being unbonded to said ribbons but being constrained by said at least two other segmented bonds, said at least two other spaced points being progressively increasingly removed from said first bonded area and being intermediate the other end of said bow form such that a length of the composite of ribbon and drawstring extends from the last of said at least two other bonds.
