Swedged Bag Tie Patents (Class 24/30.5W)
  • Patent number: 8122571
    Abstract: Closure clips and a process for the production of closure clips of strip-form or wire-form material for the closure of tubular or bag-like packagings. In the process, a substantially wave-form profile with successive first and second apex points is stamped along the strip-form or wire-form material, the first apex point forming a clip bottom, flanks respectively adjoining the first apex point on each side thereof form clip limbs that are bent over in a U-shape and the second apex point forms limb ends that are bent over outwardly with respect to the U-shape at which two adjacent closure clips are separably connected. The strip-form or wire-form closure clip material is pierced inwardly with respect to the U-shape so that a raised material portion is formed at the limb inside.

  • Patent number: 6718598
    Abstract: A two-part clip construction includes a U-shaped clip made from a plastic material with the legs of the clip spaced so as to fit over and then be deformed through a through passage in a leg locking member. The construction is especially designed to permit utilization of polymerics for forming the clips.
