Traditional way of making dumplings is to first manu

27、ally put a proper amount of stuffings on a piece of dough sheet, then cut the sheet into a suitable size or shape, and finally fold the sheet up to form a dumpling. Dumplings produced in this way may undesirably become too large or too small because the amount of stuffings to be put in is difficult

28、to control, and the thickness of the dough sheets is not constant. Furthermore, the traditional way of making dumplings by hands is unsanitary and inefficient. It may take, for instance, half an hour or so to complete dumplings for a serving of two. With the fast growing demand for dumplings, an aut

29、omatic dumpling making machine is indeed in great need. SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide an automatic dumpling making machine wherein a series of operations required to complete a dumpling such as dough sheets delivery, stuffings feeding, dough sheets

30、 cutting and folding, and dumpling product removing etc. are performed automatically.Another object of the present invention is to provide an automatic dumpling making machine wherein the thickness of dough sheets and the amount of stuffings to be fed in can be readily controlled.Still another objec

31、t of the present invention is to provide a compact automatic dumpling making machine which is efficient and sanitary in making dumplings and consumes very little power.Other objects and advantages will become apparant from the following detailed description of the present invention with reference to
