Seam types for Rosin press filter bags
This method employs frictional heat caused by high frequency mechanical oscillations.This method employs frictional heat caused by high frequency mechanical oscillations. This creates the heat required for welding and the material is plasticised. This type of seam should eliminate gaps for material to escape through and could be applied to any micron fabric.
Weakness: This seam was by far the weakest of all the seams.It did not hold up even under light pressure. Material easily escaped through the seams.
A process by which materials to be joined are heated causing the thermoplastic materials to melt. They are then compressed by applying pressure, which causes an intermingling of polymers. A seam is formed as the material cools and solidifies. This seam should create an impermeable seam. Disadvantages are seam stiffness and fiber degradation caused by excessive heat.
Weakness: This seam was stronger than ultrasonic seaming. But not as strong as sewing. We saw some promise in this method for hash processing, but due to the high heat used to make the seam, it can’t be used on smaller micron fabrics.
The advantage of traditional sewing is strength. The disadvantage is the stitch leaves gaps in the seam that can allow material to pass through the seam.
Conclusion: This seam was by far the strongest. The mesh fabric will tear before the seam blows out.
