The folding method of the conventional paper pallet support member discloses: a method of integrally folding and forming a paperboard material, which is to fold the two sides of the paper sheet to the middle first, and then to use the paper sheet center line to the entire paper sheet. In the opposite direction, the end of the cardboard is bent to the sides to form a T-shaped cross-sectional structure with a thickened top.

However, referring to FIG. 1, the folding method of the existing paper pallet support member 5 can only fold a single cardboard into a T-section structure with a thickened top portion, and can no longer be folded into a top portion and the bottom portion is thickened. The I-section structure causes the strength of the portion 51 of the top portion 51 of the support member 5 to be sufficient, and the strength of the bottom portion 52 is insufficient, resulting in the height of the socket 521 provided at the bottom portion 52 for the insertion of the stacker arm of the stacker, due to the strength of the bottom portion 52. Insufficient to set high enough, when it is assembled into a mesh paper pallet base (not shown), the two arms of the stacker are easy to collide to the bottom 52 due to insufficient height of the bottom 52 jack 521 The side wall 522 causes the side wall 522 to be damaged to cause the entire paper pallet base to be unusable; and the folding method of the existing paper pallet support 5 is to fold the two sides of the paper sheet to the middle first, so that The bottom central cardboard has only a downwardly folded portion, and has only one side of the cardboard supporting force, and the supporting force is relatively poor to carry a heavier article, and is easily deformed by heavy pressure.

Moreover, the structure of the support member 5 which is folded by the conventional folding method has a top surface 53 which generates a crease depression 531 which will cause a gap between the top surface 53 of the support member 5 and When the mesh paper pallet base composed of the support member 5 is embedded, the finished pallet of the paper pallet base after being glued to a carrier plate is caused by the top of the support member 5 The unevenness of the surface and the relationship of the creases IHJ 531 cause the adhesive carrier sheet to be in close contact with the support member 5, so that the carrier plate and the mesh paper pallet base are easily loosened and damaged after a period of use.

Moreover, the support member 5 which is folded by the folding method of the conventional paper pallet support member 5, and the paper sheet with strong cardboard strength cannot be completely exposed outside the support member 5 (that is, the strong-strength paper sheet and The weaker backing paper mixes, causing the support 5 to fail to achieve optimum strength to carry heavier loads. It can be seen that there are still many shortcomings in the above existing folding methods, which is not a good design and needs to be improved. Summary of the invention
