Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
A reshaping apparatus for reshaping a cylindrical container body having a soldered side seam, said reshaping apparatus comprising a plurality of angularly spaced pairs of vertical posts between which the cylindrical body is adapted to be disposed, said pairs of posts including a pair of posts movable relatively to each for clamping said cylindrical body along the lEngth of said side seam, said remaining ones of said pairs of vertical posts being movable relative to each other to displace said cylindrical container body into a generally rectangular cross-section prior to stretching said container body when said can is held clamped at said side seam thereby to reshape said cylindrical container body.
Claim 2
Dependent Claim
111 words
A reshaping apparatus for reshaping a cylindrical container body having a soldered side seam, said reshaping apparatus comprising a plurality of angularly spaced pairs of vertical posts between which the cylindrical body is adapted to be disposed, said pairs of posts including a pair of posts movable relatively to each for clamping said cylindrical body along the lEngth of said side seam, said remaining ones of said pairs of vertical posts being movable relative to each other to displace said cylindrical container body into a generally rectangular cross-section prior to stretching said container body when said can is held clamped at said side seam thereby to reshape said cylindrical container body.
Claim 3
Dependent Claim
36 words
The invention as defined in claim 1 wherein said remaining ones of said vertical posts grip said container body so that said can body is free to slip therebetween as said reshaping means stretch said body.
Claim 4
Dependent Claim
