Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
274 words
Container forming apparatus comprising: a frame adapted to receive a generally cylindrical hollow side member and a generally circular end member having a flanged edge and to hold such members so that said end member is inside and adjacent the end of said side member; first and second crimping rolls positioned adjacent one another; means to move said frame relative to said crimping rolls so that the end of a side member and the flanged edge of an end member on said frame enter the region between said rolls; bending means adapted to receive a strip of material and bend same to transform the strip of material into a channel member; cutting means; guide means positioned between said cutting means and said crimping rolls, said guide means comprising a first guide member positioned to lift one edge of the channel member over the end of a side member and the flanged edge of an end member on said frame when said frame is adjacent said crimping rolls, and a second guide member positioned to locate the channel member over said end of a side member and said flanged edge of an end member when said frame is adjacent said crimping rolls; means to pass a strip of material through said bending means and said cutting means to said guide means, whereby a resulting channel member is positioned over the end of a side member and the flanged edge of an end member on said frame when said frame is adjacent said crimping rolls; and means to rotate said crimping rolls to rotate the side and end members and to crimp the channel member thereon.
