Abstract
Abstract A method of producing bales of agricultural products includes wrapping a bale with a wrapping material, discharging the fully wrapped bale from the press, and forming a new bale, with an intermediate storage of the product in the press retained as short as possible by overlapping of some of the method steps, so that the time required from the beginning of wrapping of a finished bale to the beginning of forming a new bale is very short.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
An improved method of producing round bales of agricultural products wrapped by a wrapping material, with the steps of continuously supplying a product into a press; transporting the product into pressing chamber for forming a bale; wrapping the bale with a wrapping material; intermediately storing the product and interrupting the supply of the product into the pressing chamber during the wrapping step; separating the wrapping material after wrapping of the bale; opening the pressing chamber; discharging the wrapped finished bale out of the pressing chamber; closing the pressing chamber; further transporting the intermediately stored product and the continuously supplied products into the pressing chamber so as to form a new bale wherein the improvement comprises: starting the opening of the pressing chamber before separating the wrapping material; and starting of the closing of the pressing chamber in response to sensing of the discharged bale during said discharging step by a sensor, and transporting the intermediately stored product and the continuously supplied product into the pressing chamber before the chamber is fully closed.
Claim 2
Dependent Claim
