The Edge Banding Machine's Wood Has A Small Longitudinal Shrinkage, Which Is About 0.1%.

Thermal transfer edge banding machine uses wood to dry and wet the wet material in the air, and its moisture will gradually evaporate, causing the size and volume to shrink. This phenomenon is called sub-shrinking, thermal transfer edge banding machine dry material in humid air. It will absorb moisture and cause swelling of size and volume. This phenomenon is called swelling.

The shrinkage of various woods is different. Even the same piece of wood has the difference between vertical and horizontal expansion and contraction, while the horizontal direction has radial and chordwise points. The edge banding machine's wood has a small longitudinal shrinkage, which is about 0.1%. It can be omitted. The edge banding machine's wood has a large lateral expansion, especially the string-to-dry shrinkage is 6- 12%, the diameter of the meat is reduced to 3-6%. The rate of swelling of the wood is uneven, and it gradually slows down and then gradually slows down.

After the wood of the edge banding machine is dried, it causes uneven shrinkage. Due to the difference in radial and chordwise shrinkage, the wood changes its original shape, causing warpage, local bending, twisting, anti-wing, and vertical cracks.
