ABSTRACT:
A twist tie feed device is provided for twisting together the ends of a tie ribbon which encircles a product including a base plate. A twist head assembly can be mounted on a base plate and receives a first end of a tie ribbon which encircles the product and a second end of the encircling tie ribbon and will rotate about itself to twist the tie ribbon about the product. Positive drive wheels and idler working in conjuction feed the ribbon in one of a first direction towards the twist head assembly and a second direction away from the twist head assembly. The positive drive wheels can contact the ribbon at one side and the idler can contact the ribbon on the other side to apply a positive drive force to the drive the ribbon as it passes between the drive wheels and idler. The ribbon can be fed in the second direction away from the twist head assembly, thereby tightening the ribbon about the product. Once the ribbon attains a certain tension, a microprocessor can cease the ribbon feed, whereupon the ribbon can be tied and the twist head assembly can twist the ribbon about the article.
