Abstract: A crimping tool for applying a deformable crimp seal onto overlapping layers of strap material includes a head and pairs of jaws disposed in the tool head and operably mounted thereto. Each pair includes opposingly oriented jaw elements. A shear extends between and is operably connected to the jaw elements. The jaw elements have an inwardly oriented crimping portion with a tip having a tapered portion terminating at a free end. A pair of handles are operably connected to the jaw elements and to one another. A side plate is operably connected to the jaw elements and shears and includes a centrally disposed slotted opening. When the tool is in a closed position the jaw elements of each pair align with one another and the free ends of the opposingly oriented jaw element tips overlap in a direction transverse to the jaw elements.
Abstract: A crimping device for securing a seal member onto overlapped end portions of a strap material includes at least a tool head, operating and stationary handles, two rows of crimping elements having at least a pair of shears and oppositely situated pair of jaws extended between the pair of shears. The crimping elements may be disposed in the tool head and connected with the handles so that at least one row of crimping elements crimps a seal while at least one row is idle when the handles move away from each other. In an embodiment, the handles can make an inward stroke only when a full jaw-closing outward crimping stroke is completed. At least one row of crimping elements crimps the seal with an inward movement of the handles while at least one previously actuated row of crimping elements is not involved in closing the seal.
Abstract: A tensioner is disclosed for applying a non-metallic strap around a load. The tensioner includes a base and a lever that can pivot. A drive gear is mounted to the lever and rotates clockwise. A tension gear engages the drive gear and rotates counter-clockwise. A feed wheel is coupled to the tension gear and rotates counter-clockwise. A gripper is attached to the base. The strap is held stationary by the gripper, wrapped around the load, is fed underneath and is in contact with the feed wheel. When the lever is rotated down, the feed wheel rotates counter-clockwise. The strap is pulled toward a distal end of the tensioner and is tensioned in a clockwise direction around the load.

Abstract: A crimping tool for installing a metal crimp seal onto overlapping layers of plastic strap material includes a tool head, at least three pairs of jaws disposed in the tool head and operably mounted thereto, each pair including opposingly oriented jaw elements and each pair being spaced from its adjacent pair, and at least two crimpers, one crimper disposed between adjacent pairs of jaw elements, the crimper extending between the jaw elements.

Abstract: A crimping device constructed with a plurality of shares bent in a middle section with offset pairs of jaws mounted thereon. The bent shape of the shares allows offsetting the opposing rows of jaws so that they overlap without interference. This means that each of the jaws can be identical in conformation. When closed on a seal, the crimping device creates a staggered pattern of multiple crimps so that a maximum interior surface area of the seal is pressed into the band being sealed. The working surface of the shares is shaped as an arch so that when used in conjunction with the uniquely shaped working surfaces of the jaws, the device causes the seal to be arched upward during the crimping operation. This arching further increases the rigidity and holding strength of the seal to be formed.
Abstract: A band tightening tool is provided having a pair of stamped members, each of which has the same structural configuration. The two stamped members are fixedly joined together by a welding process. When connected together, the two stamped members define a channel, a pair of cross holes and an open area. The two cross holes receive a band tightening mandrel having a mandrel slot. The cross holes and mandrel include cooperating retaining elements to prevent unwanted separation of the mandrel from the cross holes. To tighten a band about an object, the end portion of the band is inserted through the channel defined by the two stamped members so that the band end portion can be attached to the band tightening tool. Rotational movement of the band tightening mandrel causes the band to be tightened about the object. In so doing, the open area between the channel and the cross holes acts to accommodate the band portions being wrapped around the mandrel.
