Seaming is the most demanding part of dryer fabric making. It requires a lot of handwork, thus it is the most expensive and time-consuming phase. Seaming doubles the value of fabric so it is essential that the heatsetted fabric is perfect. In seaming the seam area is rebuilt for many centimeters length to retain the high tensile strength of the dryer fabric. The seam must also be as similar as possible with the weave pattern to avoid the seam marking. The picture below shows a common warp loop seam.

       

In second heatsetting the length of fabric is checked and seam is inspected. Also edge reinforcement is applied in this production phase. As paper web does not cover the edges of a dryer fabric, the edges are subjected to greater strain than the paper web area. Therefore the edge reinforcement is applied to the edges to improve long term heat resistance and abrasion resistance.

Packing is it encompasses a lot more, not just putting the polyester mesh inside a box. Final inspections are made to verity the air permeability, length and width. Fabric is also inspected throughout visually and a trial seaming is made for the seam to assure the reliable seaming at the customer’s site. Edges of the polyester mesh are also checked and the ordered seaming assists are added into box. Some customers have special requests concerning the package and markings, so they also have to be taken into account.

In packing phase fabric has gone through all processing points and it has reached its maximum value. It is essential that everything in this phase goes as designed; this is the last point to make final inspections before customer. The most frustrating mistakes can be made in packing if a high quality product cannot be installed due to a packing error. This matter comes out particular with new customers having special wishes regarding packing and the package. When a product enters to the packing stage, there has to be well-designed up-to-date packing instructions available.
