Selection of Traverse unit

Traverse unit model can be selected considering the total force acting on the traverse unit as applicable including the winding tension and twisting forces in the material to be traversed, Weight of guide assembly and traverse unit, Linear speed and Stroke length, Frictional load, Distance between traverse assembly and capstan (the more the distance force required will be less) and any other forces applicable. For calculation, a Model need to be preselected by approximately estimating the force required as above.

Force F (Kg ) = 0.25 (M X V / T ) + Fr +Fz + 0.12(MXG ) + Fw

M (Kg) = Total weight to be traversed
V = Max Linear speed (Meters per second)
T = Reversal time (Second). Refer Fig 73.
Fr = Kg, Friction load.
G = 9.8 m/s2 (Gravitational Force)
Fz = Additional force if applicable (Kg)
F w = Force related to winding tension. Refer Fig 6


C = Stroke length (mm)
T Kg = Winding Tension Kg (Approximately 5 to 10 % of maximum Tensile strength)
B mm = Distance between Traverse and let off point
