Abstract:
1. A brake assembly for applying pressure to a covering material that is automatically fed over a product chute of a packaging system having a clipper, comprising: a pair of spaced apart arms, each having respective gripping members, the arms configured to move toward each other a distance sufficient to cause the gripping members to contact an outer surface of an intermediately positioned product chute with an interior cavity and to move away from each other a distance sufficient to cause the gripping members to avoid contact with the outer surface of the product chute to thereby controllably selectively apply a braking force onto covering material held between the outer surface of the product chute and the gripping members, wherein the arms have opposing upper and lower portions and are each pivotably attached to a stationary common center frame member at the lower portion of each arm; and an actuation cylinder that is attached to each arm above the lower portion of each of the arms and extends between the arms so that the arms are configured to automatically controllably pivot in concert toward and away from each other; wherein the actuation cylinder is located between the gripping members and the stationary common center frame member.
