Blown Film Equipment - Dies, Towers, Take-Offs, Winders and Complete Mono and up to 5 Layer Coextrusion Systems

Price Reduced!- Reconditioned Laboratory Blown Film System - Click for details!

Wayne Yellow Jacket® Blown Film Tower & Take-off units are ideal for making blown film for laboratory testing and small production. They can be used with mono-layer and co-extruded blown film dies. Wayne take off systems are suitable for all types of flexible thermoplastics and some other types of materials. Since they are robust units, they are suited for emulation and testing for scale up on larger blown film lines. They are ideal for use with standard height 42" centerline extruders, or can be specified for use with low-boy designs. They easily accommodate up to three extruders for co-extrusion situations. Wayne Yellow Jacket® Blown Film Tower & Take-off units have some unique features that make them easy to work with:

Integrated system components are all on one base including the tower, controls, upper nip, lower nip and surface winder. There is no difficulty in aligning the different parts because they are all on one base!
Lower nip rolls and drive are included to assist in maintaining tension and stability in the film as it is taken-off. This is superior to crude lab systems that do not have a lower nip roll and simply use idler rolls which feed directly from the upper nip to the winder. Use of lower nips also helps to prevent the winder from "pulling through" the upper nip and causing additional unwanted tension on the blown film bubble. It is also impossible to use those other systems to emulate larger lines and scale up, because all large lines have lower nips! Wayne Yellow Jacket Blown Film Systems have a open / close pneumatic cylinder control of the upper and lower nips for quick and easy threading of the film.

Dual drive tach follower system is standard for continuously variable adjustment of tension. Most small blown film lines have no lower nip and a separate winder. The unique Wayne tension control system gives maximum flexibility since a pot adjustment changes the speed ratio of the upper nip rolls and the lower nip rolls to give you exactly the amount of tension you want. Optional torque control on the lower nip allows the torque of the lower nip to be adjusted easily with a pot. The Wayne system leaves these crude 'stone age' lab film take-off systems far behind!
Rolls open for easy thread through and quick release in an emergency. With one press of the emergency stop, both the upper nip and the lower nip rolls open and the drive stops for operator safety.
Surface winder is an integral part of the unit which avoids the necessity of another piece of equipment. Universally available low cost cardboard cores are used to wind samples. The winder is always there when you need it! Optional Torque Winder is available with the same speed ratio control described above, and an additional pot to adjust the torque limit of the motor for tension control.
Rotating or Oscillating Top Nip is available to assist in the prevention of uneven film which results in uneven winding. This is a major feature which is typically not found on other laboratory or small production blown film systems. This unique Wayne feature is available because of the robust construction and flexible engineering of Wayne systems.
