Abstract
Abstract A container body maker including means for forming a completed cylindrical container body and a means for reshaping the cylindrical container body. The reshaping means includes angularly spaced posts arranged to support the cylindrical container and bending means disposed between the posts. The bending means serve to depress the portions of the cylindrical body spanning the posts to reshape the body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A container body maker apparatus for reshaping a tubular container body of substantially circular cross-section into rectilinear cross-section comprising a reshaping means including a plurality of spaced supporting means for supporting said tubular container body along longitudinally extending and angularly spaced lines parallel to each other, and bending means disposed between adjacent ones of said supporting means and having surfaces disposed below said spaced lines for depressing the portions of the tubular body extending between adjacent ones of said parallel supporting means so that the tubular container body is permanently bent along said lines into substantially rectangular cross-section when said container is removed from said supporting means and said depressed portions spring outwardly into flat walls.
Claim 2
Dependent Claim
116 words
A container body maker apparatus for reshaping a tubular container body of substantially circular cross-section into rectilinear cross-section comprising a reshaping means including a plurality of spaced supporting means for supporting said tubular container body along longitudinally extending and angularly spaced lines parallel to each other, and bending means disposed between adjacent ones of said supporting means and having surfaces disposed below said spaced lines for depressing the portions of the tubular body extending between adjacent ones of said parallel supporting means so that the tubular container body is permanently bent along said lines into substantially rectangular cross-section when said container is removed from said supporting means and said depressed portions spring outwardly into flat walls.
Claim 3
Dependent Claim
29 words
The invention as defined in claim 1 wherein said bending means comprises angularly spaced blades arranged substantially radially relative to the tubular container body supported on said supporting means.
Claim 4
Dependent Claim
17 words
The invention as defined in claim 2 wherein said blades are each fixed relative to each other.
Claim 5
Dependent Claim
25 words
The invention as defined in claim 3 wherein said blades each include a tapering leading edge defining said depressing surfaces for gradually depressing said portions.
Claim 6
Dependent Claim
42 words
The invention as defined in claim 1 wherein said bending means comprises rollers disposed for rotation in a plane normal to the plane extending between said supporting means and having the respective peripheries extending below a plane containing said adjacent supporting means.
Claim 7
Independent Claim
97 words
The method of forming a tubular can body comprising the steps of initially shaping a blank into a tubular body of substantially cylindrical cross-section, supporting said cylindrical can body along longitudinally extending and angularly spaced supports and depressing inwardly the portions of the body spanning adjacent ones of supports so that the can body is bent about the supports, and allowing the depressed portions of the body to spring back into flat walls spanning the bends so that the circular cross section body is reshaped into a body of rectangular cross section when removed from the supports.
Claim 8
Independent Claim
97 words
The method of forming a tubular can body comprising the steps of initially shaping a blank into a tubular body of substantially cylindrical cross-section, supporting said cylindrical can body along longitudinally extending and angularly spaced supports and depressing inwardly the portions of the body spanning adjacent ones of supports so that the can body is bent about the supports, and allowing the depressed portions of the body to spring back into flat walls spanning the bends so that the circular cross section body is reshaped into a body of rectangular cross section when removed from the supports.
Claim 9
Dependent Claim
29 words
The method as defined in claim 6 wherein the portions of the body spanning the adjacent ones of the supports depress the portions at a location between the supports.
Claim 10
Dependent Claim
26 words
The method as defined in claim 7 wherein the portions between the supports is depressed inwardly below the plane containing the adjacent ones of the supports.
