Traverse Units

Selection of Traverse Unit

Required model for an application is selected considering the winding tension , weight of the guide assemblies to be traversed , linear speed, stroke length ,shaft sag , Frictional force on the separately mounted guide assemblies if any etc.
Extensively Used in Spooler / Take up stand of Wire drawing, Stranding, Armoring, Braiding, Extruder and other Wire Processing Machines and , Rewinding machine etc.
Separate load carrier recommended in applications , where heavy Guide assemblies or Guide assemblies having Overhang are to be used or when large twisting forces and winding tension is present in the wire to be wound.
Pre-Selection: For calculation a model is pre-selected by estimating approximately total force required considering the weight of guide assemblies, Linear speed , Winding tension , Twisting Forces, Frictional force , Distance between capstan / pay off to traverse ,Max traverse stroke length etc. and verified as calculated below

Side thrust

1. F = Calculated required Side Thrust in Kg ,
2. m = Total weight to Be Traversed (Includes the weight of the traverse unit, and parts mounted on the unit)
3. V = Max linear speed .
4. t = Reversal Time. Select from fig (4) against model .
5. Fr = Frictional Force on the guide assemblies ( Relevant only when separate load carrier is used )
5. g = Acceleration due to gravity (9.81 m/sec2)
6. Fw = Force Acting on the Traverse due to winding tension ( Ref Fig 3)

C = Max Traverse stroke length
T = Winding Tension . Approximately 5 to 10% of tensile strength of material
B. = Distance to traverse from capstan / payoff
7. Fz= Additional estimated Forces if any If the required side thrust F calculated as above is higher than the rated max side thrust of the model pre-selected , higher size model is selected rechecked as per above calculation.
We can help in selecting suitable model . Please provide following details.

A. For Winding applications.
1. Maximum Stroke length or Max Bobbin Width.
2. Maximum dia or Max size of the material to be traversed and material.
3. Max line speed or bobbin RPM .
4. Winding tension or Tensile Strength of the material.
5. Application.
6. Traverse Pitch Range.
7. Distance from capstan / payoff.

B. For any Other applications.
1. Max Weight of the material to be traversed.
2. Max Linear speed.
3. Details of application.
