AI Technical Summary
In existing technology, fitted sheets tend to loosen and bulge during the secondary folding process, affecting the folding effect after multiple folds.
The fitted sheet is equipped with a double-folding flattening device, which includes a belt conveyor, a top pressing mechanism, and a folding mechanism. The top pressing mechanism presses the top of the fitted sheet, and the folding mechanism folds it up. At the same time, the downward venting mechanism removes air to ensure that the fitted sheet is flat.
This effectively prevents the fitted sheet from becoming loose during multiple folds, ensuring a smooth folding effect and achieving a flat and easy fold.
