Method and machine for the manufacture of pom-pom bows
Abstract
Abstract AN APPARATUS AND METHOD FOR PRODUCING ATTRACTIVE POMPOM BOWS AUTOMATICALLY FROM A CONTINUOUS STRIP OF RIBBON MATERIAL IS DISCLOSED. THE BOWS ARE FORMED BY FEEDING SUCCESSIVE RIBBON PORTIONS ALONG THE CONTINUOUS RIBBON LENGTH TO A RIBBON-HOLDING MANDREL. A PLURALITY OF SUCCESSIVE TUFTED LOOPS ARE FORMED DISPOSED RADIALLY ABOUT THE MANDREL. IN THE FORMATION OF EACH LOOP THE RIBBON IS TWISTED 180* ON ITS LONGITUDINAL AXIS PROXIMATE TO EACH POINT OF ATTACHMENT OF THE RIBBON TO THE MANDREL. IN ORDER TO ACCOMPLISH THE TWISTING, THE RIBBON IS PROVIDED WITH REDUCED WIDTH AREAS. THE REDUCED WIDTH AREAS ENHANCE THE TWISTABILITY OF THE RIBBON AND ENABLE PROPER PLACEMENT OF THE LOOPS WITHOUT HAND MANIPULATION. IN THE DISCLOSED EMBODIMENT THE TWISTING OF THE RIBBON AND THE PLACEMENT OF THE SUCCESSIVE LOOPS IS ACCOMPLISHED BY ROTARY INDEXING OF THE MANDREL RELATIVE TO THE RIBBON-FEEDING MECHANISM AS THE RIBBON IS FED TO THE MANDREL.
