It is usually connected with the ironing machine to automatically fold the ironed sheets (or square tablecloths).
According to the number of folds, it can be divided into the following four types:
1. Two-folding machine: a machine that can only be used for longitudinal two-fold folding;
2. Four-folding machine: a machine that can perform two vertical and horizontal two-fold folding;
3. Five-folding machine: a machine that can be folded twice in the longitudinal direction and three times in the transverse direction.
4. Multi-folding machine: a machine that can perform longitudinal three-folding and horizontal three-folding or more.
According to the number of objects that can be folded at the same time each time, it can be divided into single-channel machines and multi-channel machines. The former can only fold one sheet or tablecloth at a time, and the latter can fold 2~4 small objects (such as small tablecloths, pillowcases, etc.) at the same time in addition to the single-channel function. Usually called two-channel machine or four-channel machine.
