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 is mounted on the 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 article. Two positive drive wheels feed the ribbon in one of a first direction towards the twist head assembly and a second direction away from the twist head assembly so that the wheels contact the ribbon at its top and bottom to apply a positive drive force to the drive ribbon as it passes between the drive wheels. A drive assembly is operatively coupled to the twist head assembly and the drive wheels for driving the positive drive wheels and twist head assembly.
