Technical Field

[0001] The utility model relates to the technical field of disposable slippers, in particular to a forming mechanism for a slipper upper. Background Art

[0002] Disposable slippers are mainly used in hotels, beauty salons, dust-free workshops, etc. because of their low price, convenience, and sanitation. Disposable slippers are mainly composed of a sole and an upper. At present, the production of disposable slippers has developed from traditional manual and semi-automatic to automated production. The automated production equipment of disposable slippers is also in a continuous development process. In the production process of existing disposable slippers, the sole fabric is generally processed, and then it is combined with the processed upper on the other side and welded or bonded to complete the overall processing of the slippers.
