Paper Cup Making . Starts with large rolls of paper board stock. Rolls can be various widths depending on cup making machine. Roll is fed thru machine where is is formed around a cylinder and glued along the edge. Next the cylinder goes along the machine where a paper board bottom is inserted and also glued into place.. The paper board stock can be either poly or wax coated to make it leakproof. The wax or poly coatings can be added as the cup is being formed, or it can be applied to the board stock before the cup is formed. If the cup is going to be printed the poly coating or wax coating is applied after the printing is done. Print is done on the roll stock before the cups are formed.. - . The manufacturing of the paper begins after the fibre from the trees or other sources is gathered. This starts with pulp making. Logs are first cleaned of impurities, then de-barked, and subsequently turned into wood chips.. These wood chips are converted into wood pulp. Separating cellulose from the lignin components of the wood produces wood pulp. Pulping can be done through mechanical or chemical processes.. In the mechanical method of pulping, wood is chopped or grinded. This is done to sift all the unneeded particles of the wood. The cellulose fibres will remain intact.
