Tension and velocity of fundamental belt-roller system under load operation(1)The sum or the difference of tensions of belt tight and loose ide equals twice of initial tension or a load weight respectively.(2)The slip between the belt and rollers increases with the load weight and then velocities of belt and driven roller decrease.(3)A simple analytical model is proposed for calculating the belt tension, friction force and belt velocity. When reaction forces acting on the belt and rollers are given, the tension, strain and velocity of belt can be evaluated.Flexible media transfer by pinching belts(4)The slip between the drive belt and driven belt increases with belt pressing force, friction coefficients and belt initial tension.(5)The slip of a media against the driven belt increases with the belt pressing force and belt initial tension, while it is not affected with the effects of the media thickness and friction force. The media moves a little bit faster than the driven belt.
