A Simple Device for Making Paper Pots

A simple hand-operated machine for making pots from common roofing paper was devised at the U. S. Southern Great Plains Field Station in 1936. Its principal parts are a wooden block to force a previously cut strip of roofing paper (Figs. 1 & 2) into a mold and makes it U-shaped. The parts of the strip protruding above the block in the mold are then creased by folding them over the block (Fig. 3). The device is built permanently into a rough table and has a foot treadle with a spring release for raising the block out of the mold (Fig. 4). After the paper-wrapped block is raised from the mold, the creased paper is slipped off and the overlapping parts are fastened together with a common hand stapler such as can be bought at any stationery store.
