Band saw blades and band knives slicers are a crucial piece of equipment in a variety of industries, including food processing, cutting paper, cardboard, metal, foam, etc. These are blades designed to ensure precise cuts, maintain efficiency, and increase productivity in whatever processing they are used in. However, the longevity and performance of a bandsaw blade is significantly affected by the way it is handled and stored, as well as the way it is tensioned on the machine’s pulleys. In fact, one of the essential skills every operator should have is precisely that of properly bending, opening and reversing a bandsaw. Incorrect handling can cause damage, reduce cutting efficiency and even pose safety risks.
ECOGEO guides you through the essential steps to properly handle blades and bandsaws to get the most out of your equipment.
Band saws and their main uses
Band knives slicers and band saws are versatile cutting tools that are used in various sectors and industries. They are, basically, a continuous band of smooth or toothed metal that is stretched between two wheels called pulleys. In industry, band saws are indispensable for performing tasks such as:
1. Food cutting, for optimal processing of meat and fish, bread and baked goods, whether fresh or frozen.
2. Packaging and recycling, for cutting plastic materials.
3. Metal cutting, for a variety of applications and uses.
4. Because of the versatility that band saws can offer, they can also be used for different types of cutting in a range of industries, such as bedding and foam cutting accessories.
Why bandsaw blades and band knives slicers need to be properly stored
While it is generally true that a bandsaw blade is unlikely to break if not properly bent, because it is made of strong and durable materials, it is certainly more likely that a blade that is not stored and maintained in the optimal way is more prone to breakage during use. Consider that this type of problem can result in the replacement of the entire machine, looming in not insignificant costs.
Proper storage of bandsaw blades is critical to prolonging their life and maintaining cutting performance. When band knives and band saw blades are not properly stored and handled, several problems can, in fact, arise:
– Damage to blades. Unprotected blades may bend erratically, resulting in unusability.
– Safety hazards. Exposed blade teeth can pose a serious risk of injury to personnel if blades are not properly bent and stored.
– Efficient space management. Unbent blades take up more space, making effective management of storage areas difficult.
Safety devices required for handling bandsaw blades
Handling blades and band saws requires strict adherence to safety protocols to avoid accidents. The sharp profile and tension of these blades mean that even a small mistake can lead to serious injury. Before you start bending, opening or flipping a bandsaw blade, make sure you have the following safety devices in place:
1. Cut-resistant gloves, which protect your hands from cuts and abrasions.
2. Safety glasses, protect your eyes from debris or sudden blade movement.
3. Closed, heavy shoes, to avoid injury from falling blades or tools.
4. Thick, long-sleeved clothing, but make sure it does not get caught in the blade.
Check that the work area is clean and free of obstacles before you start handling the blade. This will reduce the chances of accidents and easier workmanship.
How to properly bend a band saw: step-by-step guide
Bending a bandsaw blade correctly is essential to store it safely and to prevent damage. Follow these steps to properly bend your bandsaw blade.
Step 1: Lay the blade on a flat surface
Place the blade on a flat surface, such as a clean floor or workbench. Make sure the teeth of the blade are facing you to avoid accidental cuts.
Step 2: Hold the blade in place
With one hand, hold the top of the blade and use your foot to secure the bottom against the floor. Make sure the blade is positioned about an arm’s length away from your body.
Step 3: Create a circle
With both hands, carefully push the blade down so that it begins to bend in the center. As the blade begins to bend, twist your arm and rotate your wrists inward to create a loop. This movement will cause the blade to naturally roll in on itself.
Step 4: Secure the blade
Once the blade has been bent into a circular shape, secure it with a clamp. This will keep it in place and prevent it from unwinding during storage.

How to properly open a bandsaw blade: the tutorial
When it is time to change a bandsaw blade, it is essential to know how to open it once you have received the supply. Or more simply, the bandsaw should be opened after it had been stored for a period of disuse.
Step 1: Prepare the work area
Make sure the work area is clear of any obstacles and wear all necessary safety equipment.
Step 2: Cut the fastener
Using a pair of bolt cutters or scissors, carefully cut the clamp that closes the blade. Be careful, as the blade may open.
Step 3: Identify the lugs
Hold the blade by its loops with one hand on each loop. Make sure you have a firm grip on the blade to prevent it from unwinding too quickly.
Step 4: Slowly unwind the blade
The goal is to control the movement of the blade to prevent it from snapping open, causing injury or damage. First take one flap with one hand and hold the other two with the other. Create a cross, take the circle in the middle and then let go of the blade at the cross.
Step 5: Lay the blade down
If it is not a new blade, once it is fully open, lay it on the ground and inspect it for signs of damage or wear before installing it on the machine.

How to reverse a bandsaw blade: the complete guide
Reversing a bandsaw blade is a technique used to correct the orientation of the blade teeth, a procedure to be performed when there are new needs and requirements for the machinery that uses it. Follow these steps to reverse a bandsaw blade safely.
Step 1: Grasp the blade
Hold the blade with both hands, palms facing inward and thumbs on the outside of the blade. The teeth should be facing you and the smooth side of the saw facing outward.
Step 3: Rotate the blade
Hold the blade fixed to the ground on one side with one foot. With a firm grip, push down and rotate your wrists, causing the blade to tip inward, releasing the blade from your foot. This movement will reverse the direction of the teeth.
Step 4: Blade inspection
After reversing the blade, inspect it to make sure the teeth are oriented correctly for the cutting application.
Step 5: Installing the blade
Once the blade is oriented correctly, you can install it on the machine and begin cutting operations.
