IMPROVEMENT ENGINEERING SOLUTIONS FORMING PARTS OF A CARDBOARD MACHINE

The process of forming a cardboard canvas is described. The recommendations on the selection of actual designs of forming parts of cardboard machines, including for the production of multilayer cardboard, are given. To reduce the probability of formation of fiber bundles in the formed cardboard canvas, an engineering solution is proposed. It is to improve the channels of paper mass in the mass startup device by installing flow turbulators. The comparison of the predicted productivity of the cardboard machine before and after its improvement is given. It also shows the estimated performance of the cardboard machine before and after its modernization at different speeds of the cardboard web and their growth.
