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.

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.

A hand held and operated set of fastener clip pliers is provided which is useful to secure together reinforcement steel members, for example, those used in concrete construction, upholstery and fencing. The fastener clip pliers are comprised of a lower handle and an upper handle. The lower handle has at least two first prongs that define at least one intermediate slot between. The upper handle is pivotally connected to the lower handle such that the upper handle and lower handle can pivot to an open position and to a closed position. The upper handle has at least one second prong dimension to fit within an intermediate slot in the closed position. A fastening clip is provided that has a small extension protruding therefrom for manipulating and properly placing the fastening clip around the steel members prior to securing the fastening clip to the steel members.

A clip that can be either permanently affixed to a tube or removable from a tube having foldable wings is folded about the tube allowing the user to fully extrude the product contained within the tube. In order to retain the folded shape of the tube, the clip has foldable wings, which are folded around the tube.

A twist tie made of two dissimilar polymers forming a composite tying material that may be twisted upon itself forming a closure for a bag, container or bundle. A flat elongated ribbon like thermoplastic substrate (20) has a thermoplastic monofilament (28) disposed generally in the middle of one side and is bonded in place forming a homogeneous joint (40). Another configuration of the monofilament utilizes a pre-formed irregular shape singly or in opposed pairs. A second embodiment utilizes a ribbon of paper (26) laminated underneath the substrate.

In U-shaped closing staples for bags and flexible tubes, which staples are made of strip material and consist of a crosspiece (7) and two legs (4) and in which the leg ends of the staple have been bent off outwardly to constitute a connecting web (2), by which the staple is severably included in a train (1), the severing of each staple from the train (1) will result at the severing location in the formation of burrs, which protrude beyond the strip width of the staple and may result in damage to the closed wrapper and to other wrappers. An apparatus for closing bags and flexible tubes by means of such closing staples comprises a closing punch (9), which acts on a die (8) and is formed in its active surface (29) with a groove (10), which has the same width as the closing staple and has a depth which is smaller than the total thickness in which the legs are subjected to the closing operation. During the closing operation the side wall faces of the groove (10) guide the leg ends (6) and ensure that the staple leg ends (6) firmly engaging the staple legs (4) on the outside will be embossed without a formation of a burr.

U-SHAPED CLIPS OF THE TYPE EMPLOYED FOR SEALING SAUSAGE CASINGS, PLASTIC BAGS AND THE LIKE ARE FORMED WITH ARCUATE SURFACES ON THE EXTREMITIES OF THE OPPOSED LEGS FOR THE PURPOSE OF ENHANCING THE SEALING OPERATION WHEN THE CLIP TO BE SEALED. A NOTCHING AND SWAGING PUNCH IS APPLIED TO THE WIRE FROM WHICH THE CLIPS ARE FORMED TO PROVIDE ARCUATE SURFACES ON THE WIRE PRIOR TO CUTTING THE WIRE INTO THE LENGTHS FROM WHICH THE CLIPS ARE FORMED.
