The automatic bale strapping mechanism can be an integral component or series of components to a conventional baling press. The bale strapping mechanism includes a draw and cutter assembly comprising a mobile draw carriage that draws strapping material a predetermined distance for cutting. The bale strapping mechanism can also include a dispensing mechanism which dispenses strapping material and an insertion assembly which carries strapping material through an extrusion chamber chute of a baling press. Methods of automatically drawing and cutting strapping material are also an aspect of the present invention. ## Claims ### Claim 1 An automatic bale strapping mechanism comprising: a strapping insertion assembly comprising at least one inserter shaft that carries strapping material through an extrusion chamber chute of a baling press; wherein said at least one inserter shaft comprises a carrying end that engages the strapping material and wherein said carrying end comprises a strapping material support that holds the strapping material in position at the carrying end during travel through said extrusion chamber chute; a draw and cutter assembly comprising a mobile draw carriage and a mobile draw carriage frame for supporting said mobile draw carriage; and wherein said mobile draw carriage comprises a main vertical support and wherein said mobile draw carriage frame comprises at least one track in motile engagement with said mobile draw carriage and establishing a horizontal plane along which said mobile draw carriage moves. ### Claim 2 (depends on 1) The automatic bale strapping mechanism of claim 1, wherein said strapping material support comprises a trench upon which said strapping material rests. ### Claim 3 (depends on 2) The automatic bale strapping mechanism of claim 2, wherein said strapping material support comprises two flanges flanking said trench. ### Claim 4 (depends on 1) The automatic bale strapping mechanism of claim 1, wherein said strapping material support comprises a notch that produces clearance between said strapping material and said strapping material support. ### Claim 5 (depends on 1) The automatic bale strapping mechanism of claim 1, wherein said mobile draw carriage comprises a strapping material transport. ### Claim 6 (depends on 5) The automatic bale strapping mechanism of claim 5, wherein said strapping material transport comprises a roller comprising a substantially non-abrasive surface. ### Claim 7 (depends on 5) The automatic bale strapping mechanism of claim 5, wherein said strapping material transport is mounted to a transport post. ### Claim 8 (depends on 7) The automatic bale strapping mechanism of claim 7, wherein the transport post is mounted to a slide bar slidably engaged to the main vertical support of said mobile draw carriage. ### Claim 9 (depends on 1) The automatic bale strapping mechanism of claim 1, wherein said mobile draw carriage comprises a cutter blade. ### Claim 10 (depends on 9) The automatic bale strapping mechanism of claim 9, wherein said cutter blade is fixedly mounted to a cutter block and wherein said cutter block is fixedly mounted to said main vertical support. ### Claim 11 (depends on 9) The automatic bale strapping mechanism of claim 9 further comprising a strap retaining block pivotably attached to said main vertical support. ### Claim 12 (depends on 11) The automatic bale strapping mechanism of claim 11 wherein said strap retaining block comprises a notch within which said cutter blade is positioned when said strap retaining block pivots and engages said cutter blade following transfer of strapping material to the cutter blade. ### Claim 13 (depends on 11) The automatic bale strapping mechanism of claim 11 wherein said strap retaining block is weighted. ### Claim 14 An automatic bale strapping mechanism comprising: a strapping insertion assembly comprising at least one inserter shaft that carries strapping material through an extrusion chamber chute from a first exterior side wall to a second exterior side wall of said extrusion chamber chute; wherein said at least one inserter shaft comprises a strapping material support that holds the strapping material in position during travel through said extrusion chamber chute and wherein said strapping material support comprises a trench which comprises a platform upon which said strapping material rests during travel through the extrusion chamber chute; a draw and cutter assembly comprising a mobile draw carriage wherein said mobile draw carriage comprises a kinetic transport post which comprises a strapping material transport mounted thereto, a cutter blade block which comprises a cutter blade mounted thereto, and a carriage frame which supports said mobile draw carriage wherein said carriage frame comprises one or more tracks in motile engagement with said mobile draw carriage for establishing a horizontal plane along which said mobile draw carriage moves. ### Claim 15 (depends on 14) The automatic bale strapping mechanism of claim 14, wherein said kinetic transport post is affixed to a slide bar which is slidably engaged to a main vertical support of said mobile draw carriage. ### Claim 16 (depends on 14) The automatic bale strapping mechanism of claim 14, wherein said strapping material transport comprises a first position and a second position along a vertical plane y. ### Claim 17 (depends on 16) The automatic bale strapping mechanism of claim 16, wherein said first position is slightly above the cutter blade and said second position is below said cutter blade in relation to the vertical plane y. ### Claim 18 (depends on 14) The automatic bale strapping mechanism of claim 14, wherein the distance between said strapping material transport and said cutter blade is about 0.25″ along the horizontal plane. ### Claim 19 A method of automatically cutting strapping material used to bind a bale comprising the steps of: (a) providing an automatic bale strapping mechanism integral to a baling press comprising an extrusion chamber chute, a strapping insertion assembly comprising at least one inserter shaft, and a draw and cutter assembly comprising a mobile draw carriage wherein said mobile draw carriage comprises a strapping material transport, a cutter blade, and a strap retaining block pivotably attached to said mobile draw carriage; (b) engaging said strapping material to said at least one inserter shaft; (c) by said at least one inserter shaft, transferring said strapping material through said extrusion chamber chute from a first side to a second side of said extrusion chamber chute and between two adjacent bales positioned within said extrusion chamber chute; (d) by said at least one inserter shaft, presenting said strapping material to the draw and cutter assembly on the second side of the extrusion chamber chute; (e) drawing said strapping material an adjustable predetermined draw distance (D) by said draw and cutter assembly; (f) transferring said strapping material from said strapping material transport to said cutter blade; and (g) cutting said strapping material by said cutter blade. ### Claim 20 (depends on 19) The method of automatically cutting strapping material of claim 19, further comprising the step of determining a length of said draw distance (D) based on a desired length of said bale prior to step (b). ### Claim 21 (depends on 19) The method of automatically cutting strapping material of claim 19, further comprising the steps of: pausing advancement of bales being formed within said extrusion chamber chute prior to step (b); advancing said bales being formed within said extrusion chamber chute prior to step (g); and wherein said step (g) is due to tension created in the strapping material by said advancement of bales within the extrusion chamber chute. ### Claim 22 (depends on 19) The method of automatically cutting strapping material of claim 19, further comprising the steps of: resting the strap retaining block upon said strapping material as the strapping material is drawn; dropping the strap retaining block to contact said cutter blade following transfer of strapping material to said cutter blade; wherein said strap retaining block comprises a notch within which said cutter blade is positioned upon contact and wherein contact with said notch maintains proper position of said strapping material upon said cutter blade.
