Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 292 words
A baling press for agricultural products, comprising means forming a pressing chamber of a predetermined width; a plurality of spaced winding rollers limiting said pressing chamber; and means for wrapping a finished product bale including a supply container for a wrapping material, a pair of drawing rollers for drawing the wrapping material, an inlet gap formed by two of said winding rollers rotating in the same direction to introduce the wrapping material into said pressing chamber, said drawing rollers being located above said two winding rollers so that a portion of the wrapping material drawn by said drawing rollers hangs vertically downwardly in direction towards said inlet gap, a separating device for separating a portion of the wrapping material and including a separating cutter movable in the region between said drawing rollers and said two winding rollers along a predetermined path, and two guiding elements located between said drawing rollers and said inlet gap formed by said winding rollers, said guiding elements being spaced from one another and extending the width of said pressing chamber, said guiding elements having different length including a first guiding element which is located closer to said separting cutter and is shorter, and a second guiding element which is located farther from said separating cutter and is longer, said second guiding element having a recess into which said separating cutter is inserted during cutting, said second guiding element also having a guiding projection extending downwardly into said inlet gap so as to allow said portion of the wrapping material to contact only one of said two winding rollers and prevent its contact with the other of said two winding rollers to thereby feed the portion of the wrapping material through said inlet gap into said pressing chamber.
Claim 2
Dependent Claim 292 words
A baling press for agricultural products, comprising means forming a pressing chamber of a predetermined width; a plurality of spaced winding rollers limiting said pressing chamber; and means for wrapping a finished product bale including a supply container for a wrapping material, a pair of drawing rollers for drawing the wrapping material, an inlet gap formed by two of said winding rollers rotating in the same direction to introduce the wrapping material into said pressing chamber, said drawing rollers being located above said two winding rollers so that a portion of the wrapping material drawn by said drawing rollers hangs vertically downwardly in direction towards said inlet gap, a separating device for separating a portion of the wrapping material and including a separating cutter movable in the region between said drawing rollers and said two winding rollers along a predetermined path, and two guiding elements located between said drawing rollers and said inlet gap formed by said winding rollers, said guiding elements being spaced from one another and extending the width of said pressing chamber, said guiding elements having different length including a first guiding element which is located closer to said separting cutter and is shorter, and a second guiding element which is located farther from said separating cutter and is longer, said second guiding element having a recess into which said separating cutter is inserted during cutting, said second guiding element also having a guiding projection extending downwardly into said inlet gap so as to allow said portion of the wrapping material to contact only one of said two winding rollers and prevent its contact with the other of said two winding rollers to thereby feed the portion of the wrapping material through said inlet gap into said pressing chamber.
Claim 3
Dependent Claim 26 words
A baling press as defined in claim 1, wherein said recess of said second guiding element is provided with an upper edge forming a counter cutter.
Claim 4
Dependent Claim 18 words
A baling press as defined in claim 1, wherein said guiding sheets are composed of an antimagnetic material.
Claim 5
Dependent Claim 17 words

Claim 6
Dependent Claim 26 words
A baling press as defined in claim 1, wherein one of said drawing rollers is driven and has an outer surface with a high friction value.
Claim 7
Dependent Claim 38 words
A baling press as defined in claim 1, wherein said drawing rollers include a first drawing roller which is driven; and further comprising means for increasing an angle with which the wrapping material surrounds said first drawing roller.
