Coater Design, ProCone die and SLC winder

A range of technologies

A range of technologies to support a variety of processes has Davis-Standard, LLC in Pawcatuck/USA developed for example the coater design. The features of the system incorporate a floor mounted docking station and independent coater modules. Each module is capable of a different process setup, but can also be programmed the same and swapped out to simplify cleaning and reduce downtime. Mechanical drives are included and only require air and electrical connections. This coater is primarily designed for narrow web applications.

The ProCone Die is engineered for blown film structures from five to nine layers for the production of barrier films. It has a stackable mandrel arrangement allowing vertical movement of mandrels within the stack. The design allows for angular movement of the mandrels relative to each other, which provides flexibility to change the layer ratios without changing extruder position. The modules, consisting of one cone and one ring, can be rotated to share an extruder or uncoupled and moved within the stack for use with another extruder. This die is available in sizes from 2 to 12 inches (50 to 300 mm).

The SLC (Sliding Lay-on Carriage) Series winders employ pneumatics instead of hydraulics for controlling the winding force. The systems are capable of wound roll diameters up to 60 inches (1,500 mm). The winder is available in widths from 44 to 134 inches (1,118 to 3,400 mm) and capable of winding rolls on 3-inch (75 mm) or 6 inch (150 mm) cores.
