Product catalog summary
Overview of the Davis-Standard Stretch Hood Manufacturing System
The Davis-Standard Stretch Hood manufacturing system is designed to produce high-quality stretch hoods using a 3-layer Vertex IBC die in combination with a Triple Lip Air Ring. This setup allows for high production rates and excellent gauge control. The system includes features such as automatic profile control and an elevator system, which work with a high-volume IBC stack on the die. The oscillating haul-off uses gussets with auto adjustment, and the SLC winder is used for producing large diameter rolls. The line is versatile and can be configured to run other FFS films and products.

Key Features
  • DSB screws ensure superior processing of resin mix, providing excellent melt homogeneity.
  • MAC 30:1 smooth bore extruders offer dependability.
  • The Vertex die provides high IBC air volume exchange for increased outputs.
  • The Triple Lip Air Ring offers a high cooling rate.
  • Easily changeable die lips allow for exact BuR control for different size markets.
  • AutoProfile control ensures the highest tolerances are achieved.
  • The oscillating nip includes a shallow gusset assembly and extra-long collapsing for improved bubble collapsing and wrinkle reduction.
  • SLC surface winder is included.

Line Configuration
  • Material Handling: Blending system with vacuum loading.
  • Extrusion: MAC 30:1 smooth bore extruders and DSB barrier screws.
  • Die & Air Ring: Vertex multi-layer stationary IBC die with Triple Lip Air Ring and Auto profile package with oscillating gauge.
