NO-THREAD® 20" or 30" carriage Retrofits

Get your money back by getting the proper Pre-Stretch level.

To Retrofit a Stretch Wrapper, with a NO-THREAD® 20″ or 30″ CARRIAGE. The carriage works with an analog sensor that interacts with the dancer bar to adjust the motor speed for corner compensation and equal tension all around the product.

Please refer to the drawing for mounting (plate). It is the distributor’s responsibility to fit the mounting plate or to have an adaptor plate fabricated for the retrofit carriage so that it can be mounted properly to the existing machine.

It is, also, the distributor’s responsibility to install and determine the feasibility of the retrofit on a competitor’s machine
