Abstract

Abstract A method and apparatus for controlling the movement of crop material in a roll forming machine utilizes a direction means mounted to the rear portion of the floor of a material rolling machine. The direction means operates to compress the material as well as directing the material during the roll forming operation. The direction means further provides a method by which a semicontinuous mode of operation can be obtained.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 189 words
Method for forming a roll of crop material in a roll forming machine having a floor and upper apron assembly between which the roll is formed, said method comprising: a. delivering a swath of crop material from a field to the floor of the roll forming machine, b. moving the material longitudinally across the floor, c. directing said material away from said floor and into contact with the upper apron under conditions where the apron is positioned in a lowered bale forming position, d. rotating said material between said upper apron and said floor, e. discontinuing delivery of said swath of crop material, f. raising said upper apron from contact with the roll of material and into a raised bale discharging position, g. conveying said roll from said floor, h. delivering a swath of crop material from the field to said floor and then directing said material away from a discharge end of said floor to thereby initiate the formation of another roll of material prior to the lowering of said upper apron to its bale forming position, and i. lowering said upper apron to its bale forming position.
Claim 2
Dependent Claim 189 words
Method for forming a roll of crop material in a roll forming machine having a floor and upper apron assembly between which the roll is formed, said method comprising: a. delivering a swath of crop material from a field to the floor of the roll forming machine, b. moving the material longitudinally across the floor, c. directing said material away from said floor and into contact with the upper apron under conditions where the apron is positioned in a lowered bale forming position, d. rotating said material between said upper apron and said floor, e. discontinuing delivery of said swath of crop material, f. raising said upper apron from contact with the roll of material and into a raised bale discharging position, g. conveying said roll from said floor, h. delivering a swath of crop material from the field to said floor and then directing said material away from a discharge end of said floor to thereby initiate the formation of another roll of material prior to the lowering of said upper apron to its bale forming position, and i. lowering said upper apron to its bale forming position.
Claim 3
Dependent Claim 208 words
Method for forming a roll of crop material in a roll forming machine having a floor and an upper apron assembly between which the roll is formed, said method comprising: a. delivering a swath of crop material from a field to the floor of the roll forming machine, b. moving the material longitudinally across the floor, c. directing said material away from an end of said floor and into contact with the upper apron under conditions where the apron is positioned in its lowered bale forming position, d. rotating said material between said upper apron and said floor, e. compressing said material during rotation between said upper apron and said floor, f. discontinuing delivery of said material to said floor of said machine, g. raising said upper apron from contact with the roll of material and into a bale discharging position, h. conveying said roll from said floor, i. delivering a swath of crop material from the field to said floor and then directing said material away from a discharge end of said floor to thereby initiate the formation of another roll of material prior to the lowering of said upper aprOn to its bale forming position, and j. lowering said upper apron to its bale forming position.
Claim 4
Dependent Claim 208 words
Method for forming a roll of crop material in a roll forming machine having a floor and an upper apron assembly between which the roll is formed, said method comprising: a. delivering a swath of crop material from a field to the floor of the roll forming machine, b. moving the material longitudinally across the floor, c. directing said material away from an end of said floor and into contact with the upper apron under conditions where the apron is positioned in its lowered bale forming position, d. rotating said material between said upper apron and said floor, e. compressing said material during rotation between said upper apron and said floor, f. discontinuing delivery of said material to said floor of said machine, g. raising said upper apron from contact with the roll of material and into a bale discharging position, h. conveying said roll from said floor, i. delivering a swath of crop material from the field to said floor and then directing said material away from a discharge end of said floor to thereby initiate the formation of another roll of material prior to the lowering of said upper aprOn to its bale forming position, and j. lowering said upper apron to its bale forming position.
