subject: Collar Machine Required: Offset Fei Daji About This Theory (i) [print this page] Any surface air in the air pressure in the general case the pressure of air in a atmospheric pressure, the pressure of feeding the surface of the heap for an atmospheric pressure, causing gas suction nozzle in the above reduction, thereby make the paper less than an air pressure above atmospheric pressure. Paper the following general less than one atmosphere pressure (mainly due to two pieces of paper caused by uneven air gap between), fill it blowing mouthpiece, volume increasing, the top paper on the "top edge" growing. When following the top edge is greater than the pressure above, the paper will have the possibility of separation. Theoretically, if the following top edge (p2) is equal to the pressure of the above (p1) and paper weights (w) s and that p2 = p1 + w, the paper can be separated. However, due to the actual process, paper weight, heterogeneity and the acceleration of separation of paper exist, the above formula be changed to p2-p1> w, the p2-p1, that is below the top edge and the pressure above the pressure difference is called , denoted by p. Then there are p = p2-p1> w. So pressure is to drive forward the essence of the paper the reasons for separation. No pressure, paper will not separate, not together with the forward movement of the nozzle. So the paper was the top up, not being sucked up.
