Strapping machines, also often referred to as banding machines, are indispensable in various industries for a range of applications. For example, they are often used at the end of a production line for efficiency or to improve the presentation of a packaged product. Which production line you use or which product you want to strap also determines which machine is most suitable for achieving maximum production.
What is a strapping machine?
A strapping machine usually places a plastic (PP or PET) strapping band around an item or pallet of stacked goods so that it is secured for transport or handling. There are several methods of holding the belt in place such as heat, friction and ultrasonic welding. The plastic strapping band is available in various sizes and strengths, so that there is a suitable solution for every product that ensures that they are held together.
There is a great variety in the various strapping machines, from small semi-automatic or “table top” machines to automatic “bow” machines. Larger fully automatic strapping machines bundle pallet loads and stacked goods for transport and storage.
Types of Strapping Machines
With semi-automatic strapping machines or operator-operated machines, an employee must manually place the product on the machine table. He then loops a piece of band around the product and inserts it into a slot to start the strapping cycle. The machine then tensions the strapping band around the product and seals the ends of the strap. Finally, the machine cuts the strap. These types of machines lend themselves primarily to light, low-volume applications because they are practical and economical.
Automatic strapping machines have an arc or belt path that leads the strap around the product to be strapped, thus relieving the operator. Often the operator can start the cycle by means of a foot switch or push button, but often this is also done fully automatically with driven conveyors and package detection technology. It automatically detects the product and positions it in the strapping zone, after which the straps are applied without operator intervention. The fastest fully automatic Reisopack strapping machine can strap a pallet with 3 straps and 4 pallet corners in 52 seconds.
Some basics of strapping machines
Each manufacturer's equipment differs in details, but they all share standard functions and features, including:
- A strap dispenser where the strapping band is placed and where the strap is supplied to the sealing head.
- A sealing head that feeds the band around the package, tensions the band to a selected tension level, seals the ends of the band together and cuts the band. The strapping cycle is completed by pre-running the strap around the track in preparation for strapping the next package. Sealing heads can be placed below, on the side or above the product, depending on the specific application conditions.
- A belt path guides the belt around the packaging (in semi-automatic machines, the operator performs this function). The lanes are a fully enclosed tunnel on most strapping machines and provide a high level of control over the strap during insertion.
