There are many products classified in this section of Automatic Paper Attaching. They are focused on folding all kinds of garments with Automatic Paper Attaching. Attention: The following garment are applied to this auto folding packing machine. Like, garment designed with many accesories, too thick coat,suits t shirts.
All machine include the following function:
1.Within the allowable value range, the folded length and width can be adjusted as you want.
2.The machine can automatically detect the length of garment, when the garment size is different, machine can intelligently identify and automatically fold according to the first folding length, so as to ensure the uniform folding length without changing the polybag. Clothes of different sizes can be folded into uniform sizes and packed into bags.
3.Machine will calculate the number of completed pieces automatically, and the alarm function for multiple
garments can be set up.
