Abstract
In a machine for twist tying a bundle of product, the tie ribbon is fed, for looping about the product to a twist head, by a feed roller. The leading end of the tie ribbon is then clamped to the twist head by a first gripper and, rearward of the feed roller, by a staking clamp and the feed roller is allowed to free wheel. The tie ribbon in the path between the feed roller and the staking clamp is then displaced laterally out of the path. The tension in the tie ribbon around the bundle is controlled by regulating the force applied in displacing the tie ribbon. While the tie ribbon is being tightened on the bundle, tie ribbon needed for looping about the next bundle is placed in an accumulator.
