THE MAKING OF PAPER CANS
The mechanical equipment necessary for a medium-size plant for making all kinds of paper cans, mailing tubes, cores for toilet paper, etc., is as follows: One slitter and rewinder, one spiral tube winder, one tube cutter, one moistener, one double-acting punch press with automatic feeder.
For the manufacture of paper cans with tin tops and bottoms, the following additional equipment would be essential: One single-acting press, one crimping machine.
All of these machines, and also accessories, tools, and extra parts, are manufactured by the Samuel M. Langston Company, of Camden, N. J., and other well-known concerns who make a specialty of paper can machinery. The Westchester Machine Sales Co., of New York City, is manufacturing a paper can seamer, used for attaching tin tops or bottoms to spiral or straight wound paper cans. The Max Ams Machine Company, of Bridgeport, Conn., is specializing in machines used for attaching ends to round, oval or oblong fibre containers.
THE SLITTER AND REWINDER
(Note: Every different diameter of a paper can requires a different diameter mandrel for both the tube winder and the tube cutter, also a different size die for the cover and bottom.)
The large paper manufacturers—those who specialize in coarse papers—supply various kinds of paper in large rolls which is suitable for the making of paper cans. The Langston slitter and rewinder will handle a roll of paper any width up to 48 inches (according to the width of the machine) and will cut this paper and rewind it into small rolls from one and one-half inches to six inches wide. These small rolls are then ready for the tube winder.
