What is strapping machine and how does it work?

A strapping machine is an electro-mechanical device that applies and secures straps around parcels or bundles to keep them together. There are numerous varieties of strapping machines available, but they all work in the same way.

Please visit our website for more information on this topic.

Here’s a quick rundown of how a strapping machine works:

• The strapped item or bundle is placed on a conveyor belt or other platform.
• A roll of strapping material (such as plastic or paper) is fed through a series of guides and tensioners by the strapping machine.
• The strapping material is trimmed to the proper length before being fed through a sealing device such as a heat sealer, a friction sealer, or a mechanical sealer.
• The sealing device connects the strapping material’s ends, creating a secure loop around the package.
• A tensioning mechanism, which tightens the strapping material to ensure that the product is secured firmly, may be included with the strapping machine.

The package is ready to ship or go to the next stage of the production or distribution process once the strapping operation is completed. Manufacturing, transportation and logistics, and retail are all industries that use strapping equipment. They are intended to be efficient, dependable, and simple to operate, and they can be operated by a single person or connected to a larger automated system.

How strapping machine works?

A strapping machine works by feeding a roll of strapping material through the machine and positioning it around the package or bundle. The machine then applies tension to the strapping material and secures it in place using a variety of methods, such as heat sealing, crimping, or knotting.

Manual strapping machines typically require the operator to feed the strapping material and manually secure it in place using a hand-held tool. Semi-automatic and fully automatic strapping machines, on the other hand, use motors and sensors to automatically feed and secure the strapping material, often at high speeds. Some strapping machines are designed for use with specific types of strapping materials, such as polypropylene, polyester, or steel, while others are capable of working with multiple types of strapping. The type of strapping material used will depend on the specific requirements of the package or bundle being secured, as well as the intended use and environment in which the package will be transported or stored.

How to use Strapping Machine?

A strapping machine is used to secure packages or bundles using straps made of plastic. Here are the general steps for using a strapping machine:

• Place the package or bundle on the strapping table of the machine.
• Make sure the package is centered and aligned with the strapping guides.
• Choose the strap material and, if applicable, the strap size.
• Turn on the machine and, if required, wait for it to warm up.
• Wrap the strap around the package, with the end of the strap reaching beyond the package’s edge.
• In order to feed the strap around the package and through the tensioner, turn on the machine.
• The tensioner will make the strap tighter around the container.
• The machine will then either heat or mechanically seal the end of the strap.
• If desired, repeat the process on the reverse side of the package.

Conclusion:- Remember to follow these specific instructions for the particular strapping machine you are using, as different machines may have different operating procedures. It is also very important to use caution when operating the machine and to follow proper safe

Strapping Machines 101: What is a Strapping Machine, and How Does it Work?

What is Strapping in Manufacturing?

Sometimes known as banders, strapping machines are a staple in various industries for a range of applications as an end-of-line system to improve efficiency and the overall presentation of a packaged product. The type of production line and product to be strapped determines what machine should be used for maximum production.

What is a Strapping Machine?

Mastek supply professional and honest service.

A strapping machine secures one or more items for handling and product transport by placing a flat strap around the perimeter. The strap is held in place by various methods, including heat, friction, and ultrasonic welds. A plastic strapping machine uses multiple sizes of thin plastic strap to ensure products stay together.

Strapping machines range from small semi-automatic or “table top” units to automatic “arch” machines, sometimes called bundlers. Larger, fully automatic machine systems secure pallet loads and shipping units for transport and storage

 

What are the Different Types of Strapping?

The main three types of strapping machines are semi-automatic or operator cycled machines, automatic or arch machines, and larger strapping machines, sometimes called unitizers. 

Semi-automatic Strapping Machines

Semi-automatic or operator cycled machines require an operator to manually place the product on the machine table, loop a length of strap around it, and insert the strap end into a slot to initiate the machine cycle. The machine then tightens the strap on the product, seals the strap ends, and cuts the strap off. These machines are economical and practical for light-duty, low volume requirements.

Go To Semi-Automatic Machines

Automatic / Arch Strapping Machines

Automatic or arch machines include an arch or strap track through which the machine feeds the strap around the product, relieving the operator of that task. These units range from operator cycled via footswitch or pushbutton, to fully automatic with powered conveyors and package sensing technology that automatically positions the product in the strapping zone and applies straps without operator intervention. Throughput speeds for fully automatic EAM-Mosca equipment may approach the 60 packages per minute range depending on a variety of product and process factors.

Large Strapping Machines / Unitizers

Larger strapping machines or systems, sometimes called unitizers, because of their function of tying multi-item product groups into secure shipping units, have similar features to the automatic machines referred to above, in a larger size, utilizing somewhat different technology. They may integrate transport and handling functions upstream or downstream of the strapper as needed. Throughput speeds reflect the pace of shipping departments, typically in the 2 to 10 unit per minute range.

How do you Operate Strapping Machines? 

Every manufacturer’s equipment is different in detail, but all share standard functions and features. Some of these features include:

• A strap dispenser where the strap coil is mounted and where the strapping is supplied to the sealing head.
• A sealing head that feeds the strapping around the package, tensions the strap to a selected tension level, seals the strap ends together, and cuts the strap, freeing the package for movement out of the machine. The strap cycle is completed by pre-feeding the strap around the track in preparation for strapping the next package. Sealing heads may be positioned beneath, on the side, or above the product, depending on specific application conditions.
• A strap track guides the strap around the package (with semi-automatic machines, the operator performs this function). Tracks are a fully enclosed tunnel in most high-speed bundlers providing a high level of control of the strap during feeding for high cycle efficiency. Larger systems typically utilize a “spring-gate” style of track which provides good but somewhat less strict control of strap feeding but is a practical solution in larger tracks using heavier, stiffer straps that need less guidance to feed efficiently.
• Fully automatic machines include a powered conveyor that moves product into and out of the machine. These machines are paired with control systems with sensors that detect product position to determine the correct strap placement position.
• The most sophisticated systems can include web-based data transfer capability to control the strapping operation and provide an information conduit as required by the user’s overall production process.

Options for Sealing the Strap Ends

There are three types of seals used in strapping machines:

• Hot blade heat seals insert a heated tongue between the overlapping leading and trailing ends of the strap loop around the package, melt the interface and press them together to form a seal. This system is very common in smaller bundlers and is a reliable means of sealing Polypropylene (PP) strapping. The smoke given off from hot blade seals when sealing polyester strap is irritating to humans, making it a rarely used technique on Polyester (PET).
• Friction welding is a tried and true method of sealing both PP and PET straps and is widely used on larger systems. The overlapping strap ends are gripped independently, with the contacting surfaces rubbing against each other, melting and ultimately fusing the ends together. Because friction systems are mechanical, they are subject to wear over time.
• Ultrasonic sealing applies a high frequency, low amplitude vibration to the strap ends, melting the interface and generating a strong seal. Ultra-sonics eliminates the smoke issue inherent in a hot blade system and simplifies the mechanics of friction systems. It is highly effective with both PP and PET strap.

Mosca manufactures sealing heads that use all three technologies and is currently the technology leader and significant practitioner of ultrasonic sealing with its SoniXs® system. SoniXs® technology has been used in Mosca strapping machines for more than ten years and is continually refined for the highest performance. Mosca’s ultrasonic technology automatically monitors and adjusts for sealing conditions and parameters on every strap cycle, providing consistently strong seals for both PP and PET straps. SoniXs® machines come with a two-year warranty on the SoniXs® components, and the systems have a demonstrated life of up to 10 million operating cycles over thousands of machines sold worldwide.
