Model JV250
2 Preset Counter Controlled
Toroidal Winding Machine
our Low-Cost Winding Machine

By eliminating some options not needed for the winding of certain applications, Jovil has developed a low-cost machine while retaining the same quality construction as in our microprocessor controlled JV100BE-2

The two main features eliminated are:

1. The Microprocessor
2. The ability to rotate the core in the CW direction.

The JV250 is available with one of two different counters:

  • The JV57 a dual preset counter with no deceleration. (Standard)
  • The LGM a four preset counter with deceleration. (Optional)

The JV250 base will accept all winding heads, core rotators, taping heads and shuttles currently used on the model JV100BE.
