The "D" Sealer is a front-action sealer that produces crimp joints. However, unlike the side-action sealer which fastens steel strap, these tools crimp the top and bottom of grit-coated seals, creating a frictional bond between the seal and the lubricated plastic strap surface.
There are three versions of the D-Sealer.
There are two plastic combination tool families: Seal-Feed Series and Tension-Weld Series.
Seal-Feed Combination Series - Seal-feed plastic combination tools are available in manual or pneumatic versions.
Seal-feed combination tools have a design which is similar to the A-Series steel tools. However, the plastic models crimp, rather than notch the seal. The series includes the AST and AMT.
Tension-weld tools join strap surfaces by rubbing them together very quickly while they are held under pressure. These tension-weld combination strapping tools do not use metal seals or buckles. The joint is very strong, however it can be easily removed from the load by turning the strapping over and unzipping the tab.
Signode pneumatic combination tension-weld tools produce two types of joints:
These designations refer to the joint's shape. The distortion in the "Z" weld provides a superior joint strength when welded at low tension.
In the chart below, the tool model, weld type, and pounds of tension at which each tool polls is listed.
|Model||Tension (lbs)||Strap||Size (in)||Weld Type|
|VXL2000Z||Up to 200||Signode Tenax Dymax||7/16" and 1/2"||Z-Weld|
|VXT-2-16||500||HS Tenax||5/8", 3/4"||Flat-Weld|
The letters "L", "M" and "H" in the tool model codes above signify that the tool is used for light, medium or high tension applications. The "Z" denotes a "Z" Weld, while the "T" indicates that the tool is used with polyester strapping (Signode Tenax Strapping).
Conventional Feedwheel Tensioners
These tools are similar to their steel cousins but the plastic version has been modified to include a second tensioning handle and a cutter.
While the plastic windlass pulls tension in the same manner as the steel version, it also cuts the strapping. Additionally, the plastic version works directly from a dispenser, eliminating costly precutting of strap.
The DLT is used with steel and plastic buckles for light duty tension applications.
Signode markets provide a number of hand strapping tools. Besides the differences already discussed above, there are other reasons for the many strapping tool options provided.
