Film extrusion lines and metalizers present a special set of challenges to roll cover manufacturers. Homogeneous surface finishes, high release properties and tight dimensional tolerances require compounding and manufacturing expertise.
Engineered compounds from Stowe Woodward address the needs of the film extruder with a family of cover compounds that deliver good surface finishes absent of voids or occlusions and with the necessary release properties for smooth film processing.
High abrasion and temperature resistance ensure that the performance properties remain viable for the life of the cover.
For spreading in cross-over direction to get an even web without creases, or to separate parallel running webs, Stowe Woodward offers spreader rolls for various applications.
Draw or Deflate
The draw, or deflate roll is used to collapse the air column from the blown film.
Excellent abrasion resistance is required to retard web path wear on the roll surface that reduces deflation capability.
Pull or Tower Nip
The pull, or tower nip rolls are used to collapse the air column from the blown film.
Excellent abrasion resistance is required to retard web path wear on the roll surface that reduces deflation capacity.
